Ядерна енергія?

Я хочу знати, що думають про використання ядерної енергії в якості основного джерела енергії в нас, чому люди так проти нього? я знаю, що відходи можуть бути використані для створення зброї, а ядерна енергетика є в даний час настільки ефективно, що навряд чи є відходи. Це чисте джерело, і повноваження по крайней мере 2/3 у Франції, а також багатьох інших країн. Нарешті, я знаю, що були випадки, такі як 3-Майл-Айленд і в Чорнобилі, які створили масу кількість радіації і загублених життів, але вони технологія змінилася, і зараз атомні електростанції безпечні. Отже, чому люди так проти?

Експерт відповідей:

Якщо ми повинні зробити це масовий перехід від газів автомобілів повністю електричних плагінів, як родстер Tesla, те, що електрику має звідкись приходити. Ми повинні мати набагато більше атомних станцій, якщо ми очікуємо, що електричний автомобіль, щоб бути основний вид транспорту в майбутньому.

ядерною державою?

Якщо ви можете відповісти на будь-який з них, що було б здорово! :)
Мені потрібна одна для АЕС
(Не копалин підживлюється) і Сонця.
Я так плутати з цього!

1. Які джерела палива?

2. Як паливо використовується для виробництва / вивільнення енергії?

3. Що спільного в тому, як вони виробляють енергію?

4. Чи є небезпека для здоров'я пов'язана з тим, як вони виробляють енергію?

5. Чому енергії, що виділяється при ядерних реакціях відбувається? Говорити про це з допомогою дослідження по силам, які тримають ядра атома разом.

Експерт відповідей:

Мій тато знає АЕС. Я запитаю в нього ...

Edit: 1. Атомні електростанції: уран 236. Його керамічний кулька 1.5 "довжиною близько 3/8ths. Сонце: Водень зливається з іншими атомами водню для створення гелію.

2. Викликає ланцюгову реакцію, сповільнюючи реакцію з модератором якого є легкій воді. Тоді це стає важкої води. Вона має велику кількість водню в ньому. Рух атомів викликає тепло, нагріває воду, створює пар і пар перетворюється в турбіну.

3. Атомні електростанції використовувати ділення ядер (атомів летить ізотопу), сонце використовує ядерного синтезу.

4. І те й інше небезпечно для вашого здоров'я! АЕС: радіаційна передозування може зробити вас хворим. L50/30: якщо населення отримує смертельну дозу, нічого більше 650 Rankins, 50% населення загине протягом 30 днів. Такого ніколи не було. Навіть не Чорнобиль. Сонце є набагато більш потужним. Ми як і раніше одержує величезну кількість сонячного випромінювання, яке руйнує наші супутники і стільникові телефони, між іншим. Життя засмаги може вбити вас задовго до атомної електростанції.

5. Атоми сповільнюються тому вони повинні послідовно ланцюгової реакції. Без води, атоми літатимуть все більш і вивільнення енергії були б несумісні. З більшої узгодженості, ви отримуєте більше енергії на надійні ставки. Вода є основним елементом безпеки атомних електростанцій. Ви не можете підтримувати ланцюгову реакцію і без нього. Має справу з іонами.

Менді запитує ...

Ядерна енергія?

Наскільки я розумію, ядерна енергетика завжди була проблема з відпрацьованим ядерним паливом та ядерними відходами. Я знаю, що маловідходних випромінювання може зберігатися до п'ятдесяти років, і сміливо disgarded регулярно сміття. Але тоді у вас є висока радіоактивного матеріалу (Plutomium, уран і все), які мають період напіврозпаду більше 100000 років.
Чи є якийсь там пояснити, якщо трансмутації працює?
І те, що деякі з основи за цим стоїть?
Основне, що робить його безпечним проводити атомної енергетики?

Дженні запитує ...

Це ядерна енергетика є життєздатним варіантом для Сінгапуру? Які ваші проблеми, якщо такі є?

Потужного державного планування комітет рекомендує використання ядерної енергії для задоволення довгострокових потреб в енергії в Сінгапурі. Що ви думаєте? Це ядерна енергетика є життєздатним варіантом для Сінгапуру? Які ваші проблеми, якщо такі є?

Експерт відповідей:

Я впевнений, що один відомий випадок в історії, виявиться, що наявність атомної енергетики так само добре, як з бомбою уповільненої дії в Сінгапурі. Аварія на Чорнобильській АЕС потужністю від 26 квітня 1986 року: http://en.wikipedia.org/wiki/Chernobyl_disaster_effects, небезпека радіоактивного аварії є те, що вона буде мати довгострокові негативні побічні ефекти і може навіть Spead в таких країнах, як Індонезія , Малайзії і навіть Таїланд і т.д., і ми можемо піддаватися рак, пухлини і генетичні порушення, щоб назвати декілька.

Насправді, Сінгапур ще страждав серйозним промислових аварій раз: грецький танкер, Спірос, вибухнув в Джуронг суднобудівний завод в 1978 році. Вона залишається найбільш промислової аварії в Сінгапурі, убивши 76.So якщо ви сказали, Сінгапур дуже ефективним місцем для АЕС, подумайте ще раз.

Шарон просить ...

Скільки атомних електростанцій повинні бути в США, щоб бути основним джерелом електрики?

Франція отримує майже 80% своєї електроенергії від атомних електростанцій, але це невелика країна, тому, скільки б електростанцій США повинні отримати близько 80-90% своєї електроенергії на АЕС.

Експерт відповідей:

Використовуючи дані за 2007 рік від www.eia.doe.gov, загальною електричною потужністю в США,

4156745 [тисяч Megawatthours]

806425 [тисяч Megawatthours] передбачено 104 атомних електростанцій (19,4%)

Тепер ми зробимо такі припущення,

Припустимо, що заводи будуються миттєво (б / с енергоємність зростає з кожним роком, а потім ви повинні грати з геометричними обліку серії і т.д., скільки часу це займає завод буде побудований і т.д.)

Всі рослини зробити той же висновок (це залежить багато що і нові рослини стають більш ефективними).

Таким чином,

Визначив вихід енергії на атомних станціях (85%)

3533233 [тисяч Megawatthours]

7754 [тисячі Megawatthours] на атомних станціях

455 рослин необхідно

455-104 = 351 рослин повинні бути побудовані.

Тепер я готовий тримати парі, що це досить близько фігура, так як ми насправді потрібно менше, так як нові рослини є більш ефективними, але з попит зростає.

Як примітку боку, ми могли б підтримати ці численні реактори, якщо ми переробляти паливо і використовувати реактори і реактори з передової, що ми називаємо складніше спектра нейтронів споживати інших лантаноїдів і актиноїдів, які не використовуються в звичайних реакторах на теплових нейтронах.

Деніел запитує ...

Як ділення ядер, що використовуються в атомних електростанцій?

Як ділення ядер, що використовуються в атомних електростанціях. Як атомні електростанції працюють? Це папери для школи. Чи є у вас пропозиції по сайтах використовувати?

Експерт відповідей:

Вона використовується з особливою обережністю і турботою.

Але свою точку зору. Що ми маємо ланцюжок перетворення енергії, починаючи з атомної енергетики і закінчуючи електричної енергії. Коротко ланцюжок виглядає приблизно так:

NE -> QE -> KE -> EE, де ядерна енергія ділення перетвориться в теплову енергію, яка потім перетворюється в кінетичну енергію і, нарешті, електричної енергії генераторів.

Ядерна енергія виходить від дефіциту маси е = (M - т) з ^ 2, де М> т-маса ядерного палива до ділення і т-маса частинки в результаті після поділу. Існує завжди менше маси після ділення, ніж раніше, що дефіцит маси перетворюється в тепло.

Тепло поглинається рідиною, зазвичай водою під великим тиском, але іноді й інших рідин, наприклад, рідкий натрій (Na) буде використовуватися. Тепла здійснюється по трубах в чан з водою під високим тиском, де тепло виходить, що воду в перегрітий пар.

Пар потім направляються в пар керованих електричних генераторів, де теплова енергія перетворюється в кінетичну енергію турбін. Турбіни обертаються генератори, які виробляють електроенергію високої напруги.

Електрика поширюється по так званої високої напруженості дротових мереж, які розподіляють енергію для оптових споживачів. Такі користувачі, як PG & E або Нью-Йорк Edison, в свою чергу, розподіляють енергію нижнього проводу напруга для живлення комп'ютера.

Огляд "Сан - Онофрі АЕС", і ви отримаєте довгий список сайтів, які пояснюють, як Сан-Onofre ядерний завод працює. Є також фотографії на деякі сайти, які ви можете вкласти у ваш документ.

Чарльз просить ...

Є атомної енергетики є єдиним рішенням по врегулюванню кризи енергії в Бангладеш?

В умовах кризи влади Бангладеш створити багато проблем. Так що ядерна енергетика може допомогти влада, щоб позбавити цю проблему. Але мені потрібна сильна логіка і також контраргумент теж.

Експерт відповідей:

Yes.Below кращі місця, щоб дізнатися більше про переваги атомної енергетики і контраргументи в будь-якому контраргументи, а також.

Кріс просить ...

Може атомних електростанцій створюють чорні діри?

Я роблю проект в галузі науки і потрібно знати: Якщо хтось для створення атомної електростанції в центральній Каліфорнії, це може створити чорну діру? І якби він міг, які умови необхідні для її створення і як це може бути випадково створив?

Будь-яка інша інформація про негативні наслідки атомних електростанцій було б корисно. Крім того, будь-які джерела ви знаєте було б здорово!

Експерт відповідей:

Ні, АЕС не може створювати чорні дірки. Великий адронний коллайдер може - насправді, це одна з причин, вони побудували. Google більше.

Один негативний вплив атомних електростанцій (за умови, що вони не вибухають), є радіоактивними biproducts, такі, як провів урану, яке має бути безпечно зберігатися протягом тисяч років.

Девід просить ...

Є ядерного синтезу використовується в атомних електростанціях для виробництва енергії, або просто ядерного ділення?

Я читав, що ядерне розподіл використовується для поділу атомів і виробляти тепло для атомних електростанцій, але що ядерний синтез тоді робити? Чи є у неї щось із цим робити?

Експерт відповідей:

Fusion дійсно відбувається тільки в ядерних бомб називається водневої бомби, або водневих бомб. Ця зброя дійсно використовувати ядерну поділ, щоб почати термоядерну реакцію між воднем і літій.

З іншого боку, ядерні реактори в даний час використовується тільки працювати на поділ, або розщеплення атома з виділенням тепла, нацистських вчених-ядерників насправді називається цей процес протягом WW2, як уран пальника, або уранової печі, хоча ядерний реактор можна використовувати й інші поділу " палива ", крім урану.

Рубрики вітрової і сонячної Q &

Лаура питає ...

Чому США протистояти атомних електростанцій?

Ліберали у Франції та інших європейських країнах охоплює ядерну енергетику, електрика працює на 80% у Франції потужність ядерної бомби.

Невже бояться, як в Три-Майл-Айленд, або фільмі Джейн Фонди Китайський синдром?

Чому європейські екологи, як те, що американські екологи ненавидите?
Супер людина-це французька ЗМІ не роблять, що відомий французький громадський, або ж французького не хвилює?

Експерт відповідей:

Економіки, в основному. Освіти, частково.

Проблема з дешевими, поновлюване паливо, що це дешево і поновлюваних джерел. Це щось на зразок історії Джона Генрі. Коли машина приходить і бере вашу роботу в якості свінгер молоток, ніщо не замінить хліб і боби. Це те ж саме, коли АЕС приходить і бере вашу роботу вугільної електростанції.

Інша проблема в тому, що ядерна енергетика вимагає високого рівня освіти і довіри. Будь-який бажаючий може з'ясувати, як спалювання вугілля. Але ядерна наука покриті багато таємниць та конфіденційної інформації, частково зберегти кількість ядерних озброєнь до мінімуму.

Це також означає, що вугільні електростанції є рішення, яке є доступним для не-науковців. Він також займає менше вчених знайти вугілля і нафта сама, вам потрібен геолог, а з 80-х роках було всього 20 років тому, є всі ще багато тих, хто навколо. Але ви не потребуєте безпеки зазорів або тяганина минулому визначення "Млин сайт" для утилізації, і вам не потрібна команда геніїв, щоб зберегти речі для вас.

В Європі, прості люди не намагаються конкурувати з урядом і дати людям енергію. Європа залежить від решти світу для такого роду інновацій. Таким чином, це менша проблема існує. У країнах третього світу, ядерні програми є кроком на шляху до ядерної зброї, що є світовою валютою і зробити те ж саме для країни, що вища освіта робить для людини, що шукає роботу з точки зору законності і приймають всерйоз у міжнародних справах . Таким чином, хоча легше кошти генеруючих потужностей існує для них, вони як і раніше буде більш про-ядерна держава, ніж в Америці.

Зрештою, коли вугілля і нафта стала занадто дорогою, щоб прибуток від, ми будемо припинити його використання, і вже є інші рішення там. Ядерна в одному з них, і ми, нарешті, будівництво нових реакторів знову, тому що це починає відбуватися.

ядерної аварії електростанції в Чорнобилі, менш імовірно, в більшості нам АЕС сьогодні, тому що?

Експерт відповідей:

Ситуація, як Чорнобильська неможливо при кожному реакторі США. Не менш ймовірно.

З одного боку, реакторів різні. На найпростішому рівні, існує зворотна залежність між температурою і потужністю. Чорнобильської бачили сплеск температури, яка шипами влади, які підскочили температура, яка шипами влади ... І так далі. Американська реактори працюють у зворотному напрямку. Ви не могли б цього.

Крім того, є багато інших охоронців безпеки в місці запевнив, що реактор не може досягти критичної рядку статусу. Scrams (закрити падіння) в автоматичному режимі за невідповідність, у тому числі загального і різкі втрати потужності.

За все, що Чорнобиль не стримування. Ні. Стримування в американських реакторах є чудовим. Ми бачили, що в три інциденту Майл Айленд, де вони невдалі речі жорстко і активна зона реактора розплавилася. Але практично немає випромінювання вийшов до публіки, і, звичайно, далекі від небезпечного рівня.

Є дуже мало залишили реакторів у світі дизайну, як Чорнобиль, і я не думаю, що є якісь ліві без стримування. І є абсолютно нульовий або роду в Сполучених Штатах.

Девід просить ...

Якщо всі АЕС в США буде закрита назавжди?

Оскільки небезпечний інцидент, який відбувається в Японії, ви думаєте, ми повинні закрити їх чи ні? Яка ваша думка?

Експерт відповідей:

Так, закрити їх все вниз і покінчити з цим токсичних відходів вони називають безпечним. Атомні електростанції не безпечні тут, у США або в будь-якій країні, всі вони уразливі для пошкоджень від землетрусів, цунамі, виверження вулканів і т.д. Ті, які говорять, що це сейф повинен бути божевільним, або мають IQ -100, тому що будь-який бажаючий може побачити, як небезпечно випромінювання і токсичних відходів він залишає. Наслідки цієї катастрофи в Японії буде відчуватися в найближчі роки в нашій продуктів харчування, кількість людей або раком (це може зайняти до 20 років після радіаційного опромінення), незаселені землі, і інші проблеми зі здоров'ям.

Існують безпечні і чисті форми вільної енергії там, але цей час придушені владою. Холодний синтез є одним з них, але є й інші, як і енергії нульової точки, гідро-, сонячної тощо, які принесуть користь планеті і людської раси.

Марія запитує ...

Чи можемо ми зараз будувати та експлуатувати безпечні атомні електростанції в США?

Це було 20-30 років після Чорнобиля та Три-Майл Айленд. Чи повинні ми над Китайський синдром?

Експерт відповідей:

Чорнобильська не було побудовано ні одного з вищих стандартів, що використовуються в іншому світі. Це була бомба сповільненої дії.

Три-Майл Айленд не був катастрофою. Набагато більше його було відзначено, що заслужили.

Це, звичайно, можна побудувати безпечну АЕС. Крім того, необхідно дуже добре підготовлені і виплачується операторами. Це з одного боку французи дуже добре. Будучи ядерним оператором заводу у Франції проходить так, як робота представляє велику цінність.

Марія запитує ...

Скільки коштує будівництво нових атомних електростанцій в США?

Експерт відповідей:

Ніхто не знає напевно, тому що там не було ні одного побудовані з 3-Майл-Айленд сталося. Ну, якщо бути точним, там не було ні одного почав з 3-Майл-Айленд (TMI). Commonwealth Edison (потужності компанії для північних 1/4th Іллінойс, включаючи Чикаго) було 4 будуються в той час, який було закінчено.

Вони регулюються Іллінойс Комісії Конгресу. "Лі нам фінська ці рослини" Коли TMI сталося, COMED пішов до комісії і попросив їх, комісія сказала: «Ви витратили так багато грошей на них, це було б марною тратою не - ми замовляємо вам фінська їх ». Тепер, коли головне - їм було наказано добудувати їх. Це змусило деяких людей в штаті Іллінойс з розуму. Таким чином, вони проголосували в новому комісарів, проти влади комісарів компанії. Тепер прийшов час додати вартість рослин на базової ставки. Нові члени відмовилися. Те ж саме, що комісія наказала побудувати заводи в даний час не дозволили їм платять за рослинами.

Commonwealth Edison виділено материнської компанії Unicom. Пізніше вони об'єдналися з PPG стати Excelon. Таким чином, будь-яке дослідження, яке посилається Commonwealth Edison, а Exelon не "останній".

Утиліта Ради громадянина являє собою групу в Чикаго, які регулярно подає в суд на комунальні підприємства з якоїсь причини вони можуть думати (електроенергії, газу і т.д.). Люди насправді дають гроші в цю групу, думаючи, що деякі некомерційні, яка бореться, щоб знизити ціни на свої комунальні послуги. Пара хлопців, які відповідають за утиліти Ради громадянина є юристами. Вони намагаються всі справи. Коли вони виграють рішення позов, вони беруть їх адвокати збори - 50% від вартості рішення. Ці хлопці не альтруїстичний - вони в ньому за гроші. Коли вони подати в суд на енергетичну компанію, якщо вони виграють, гроші на те, що позов повинен прийти звідкись. Вони не їздять ціни, вони ведуть їх.

Повертаючись до вашого запитання, що вам потрібно зробити зовсім небагато інженерних довести, що ваш проект для електростанції буде протистояти сказати землетрусу і т.д. Тобто не з дешевих. NRC (з ядерного регулювання Comittee) є всякі правила про те, щоб зібрати дані про погоду (так що якщо у вас є витік, ви можете зрозуміти, як, де вона могла б поширитися), і так, що необхідна обчислювальна інфраструктура для управління та відображення всю цю інформацію. Ви повинні побудувати в іншому місці (близько 15 миль), центр управління інцидентами.

Добре, я готовий тримати парі, що я, напевно, було подано трохи пропагандою компанії на цьому шляху, але від того, що я читав з незалежних джерел, ядерних і раніше дешевше, ніж вугілля чи нафту. COMED Раніше у вугільних електростанцій, які вони позбулися, тому що вони були занадто дорогими. Вони як і раніше є деякі дизельні geneators на «пік» використання влітку (можна не тільки наростити вгору / вниз АЕС в короткий проміжок часу, так що ці одиниці удар під час пікового навантаження - звідси їх назва "пік одиниці "). COMED також означає «спільне виробництво», де компанії, які мають свої власні генератори (багато компаній, купив їх за 2000 рік), що під час використання пік літа, вони можуть зателефонувати в компанію і мати їх запустити свій генератор і скоротити їх з потужністю від енергетичної компанії. В обмін на це, вони отримують невелику перерву на вартості електроенергії. Це економить COMED від необхідності купувати і підтримувати стільки ж генераторів.

PS: Основною причиною вартість decomissioning ядерний реактор став більш дорогим, що вони закрили єдина установа в США, які взяли високорадіоактивних відходів. Вони збиралися відкрити новий, але була зупинена протягом багатьох років. Всі ці силові повинні зберігати свої відходи в підвалі самого рослини. Таким чином, ви не можете насправді decomission він. Ви повинні дозволити йому сидіти там, і тим не менш, зберігайте його, поки він приносить ніякого доходу.

Джордж запитує ...

Чи будуть США ядерну бомбу Іран / Ірак, якщо Аль-Каїда напала атомних електростанцій в США?

Схоже, що використання ядерну зброю в якості демонстрації на Токійському затоці була ідея запропонованого режиму Трумена. Може бути використано ядерну зброю, щоб продемонструвати майстерність США "Аль-Каїди?

Що робити, якщо Аль-Каїда була ще одна атака на США. Чи будуть США використовувати ядерну зброю тоді?

Експерт відповідей:

Будь ласка! Неначе Аль-Каїда може атакувати АЕС. Більшість людей поняття не мають, як масовий їх безпеку. У мене відвідати завод один раз, і це було неймовірно, скільки безпека, яку ви бачите, не кажучи вже про безпеку, який ви не бачите.

Але це в сторону, ми будемо мати тільки світ завдяки чудовій вогневої мощі. Звичайно, ми повинні розглядати ядерну зброю в якості опції. Складна річ, однак, є те, що Аль-Каїди ховається під скелями і в печерах по всьому світу. Отже, ми повинні зробити їх для боротьби з усіма в одному місці, перш ніж ми змогли успішно їх ядерну зброю. Тому Ірак був таким генієм. Звичайно, ми порушили гніздо шершнів над на Близькому Сході, але в даний час терористи не ховаються під їх порід в їх селах більше.

Ми вбили понад 12000 ворожих військ в Іраку лише з січня. Це неймовірно, враховуючи, що вони не були головним чином іракці, а й іноземних бойовиків.

Ядерні електростанції місць в Сполучених Штатах?

Why are most of the US nuclear power plants located only in the eastern side of the country? Does this have something to do with half the country not being downwind of the reactors?

Експерт відповідей:

I think there are many reasons, mostly economic.
1. Denser population hence greater demand for electrical power.
2. Available cooling source of water for efficiency.
3. Infrastructure in place to get the power from the plant to the end user
4. More heavy industry which uses more power.
5. Political environment more people accept nuclear energy.
6. Workers available to operate the plants with required skills concentrated in the east.
7. Heavy industry to manufacture large components more concentrated in the east.

Anyplace that has enough water and is tectonically stable is a good place for a nuclear power plant. And anyplace near the ocean is a good place for a refinery.

I think the national forests would be a good place for either. We're not doing anything else with that land.

Не буде у нас буде краще, якщо ми закрили старий стиль вугільних і замінити їх на нові атомні заводи?

США отримує 50% електроенергії з вугілля.

Індія отримує 70% електроенергії з вугілля.

Китай отримує 80% своєї електроенергії з вугілля.

З іншого боку, Франція отримує 80% своєї електроенергії з ядерних.

Ми могли б показати Китаю шлях до закриття наших забруднюючих вугільних як тільки ми створили нове покоління атомних станцій на їх місце.
Нам потрібно показати хороший приклад для Індії і Китаю.

Китай активізує принаймні одну нову вугіллі кожного тижня!
Вони хочуть побудувати 55 вугільних в рік протягом 5 років поспіль.

Ми повинні також будівництво високошвидкісних залізниць на магнітній підвісці по всій країні для того, щоб стати життєздатною альтернативою повітряним транспортом і шосе.

У них є 58 ядерних електростанцій, які створюють низька вартість електроенергії в Європі. Вони мають чисте повітря будь промислово розвиненої країни через це. На відміну від США, вони заново обробити їх відпрацьованих паливних стрижнів і використовувати їх знову і знову, щоб будувати нові паливні стрижні. Через це тривалого зберігання ядерних відходів зовсім не проблема саме тут, в США

"Галька ліжко" Реактор являє собою кризу без реактора, яка є меншою, модульний реактор, який набагато дешевше і швидше побудувати, ніж останні реактори ми побудували більше 20 років тому.

У нас достатньо вугілля нам вистачить сотні років, якщо не тисячі. Проблема в тому, викиди CO2, ми створюємо шляхом спалювання вугілля. У нас є багато уранових родовищ в Канаді та інших країнах, але ми навіть не повинні продовжувати видобуток урану так сильно, якщо ми почнемо переробка наших відпрацьованих паливних стрижнів.

If we follow the example of France, we will have one nuclear power plant for every million people.

If we follow the example of France, we will start re-processing our spent fuel rods.They are so much smarter than us when it comes to nuclear energy. They had to go that way initially because they have very little hydroelectric power sources and very little coal deposits. Necessity was their incentive to embrace nuclear energy and that is the main reason why they have surpassed us in developing nuclear energy.

The new “pebble bed” reactors are some of the ones that China is in the process of building as well.

The US will finally begin building some new nuclear reactors and just in the nick of time because we need to begin shutting down the oldest ones and dismantling them as we bring the new ones on line.If you go to Cuba you will see the cars from the 30s, 40s, and 50s kept running, but none from the last 50 years!
We are almost that bad with our nuclear power plants !
Glenn B makes some excellent points and I can't think of a better country suited to the building of a national network of high-speed maglev rail transportation than Australia!

Australia is the place where the longest railroad straight away exists. I forget how many hundred miles it goes on.

They have to keep replacing their wooden railroad ties due to the hearty species of ants or termites that eat away at them.

China has the world's first maglev rail line from Pudong Airport to Shanghai which is only a 17-mile run.

It was built by the German consortium Transrapid, but does not use our INDUCTRACK technology.

What a beautiful sight it would be to see an elevated high-speed maglev rail system conveying people across the vast beautiful landscapes of Australia.
One set of tracks going in each direction with trains leaving every 10 minutes and some making tourist stops at different places along the way! The rest of the trains will continue as an alternative to air travel.
Fear is a thief!

It is the biggest thief we will ever know!

When we are ignorant about anyone or anything, we tend to believe negative information told to us about that unknown person or thing.

We start out as a blank slate, and suddenly, 100% of what we know is negative. This negative “impression” becomes the banner under which we collect further negative information that only confirms the validity of that banner.

Rumor and inuendo negatively color our impressions of historical figures like Aaron Burr and Warren G. Harding when both end up being cast in a much better light upon further objective scrutiny.

As we evaluate a given science or industry, we run into the same kind of pitfalls of distorted perceptions as a result of negative information that was formed primarily by unobjective and sloppy evaluations.

I challenge everyone to study the latest developments in the nuclear industry as well as those in the coal, solar power , wind, and ocean swell energy industry.
“China is building the world's first commercial Pebble Bed Modular Reactor (PBMR).

PBMRs differ radically from light-water reactors. They use helium instead of water to absorb heat from the nuclear fuel, eliminating the need to locate PBMRs close to major water supplies.

Rather than using uranium fuel rods, PBMRs use thousands of ceramic-covered uranium “pebbles” encased in graphite spheres. The containment facilities typical in other reactors are unnecessary because the ceramic casings make a meltdown VIRTUALLY IMPOSSIBLE.

The overall cost per unit of energy produced is calculated to be less than half of earlier reactor designs.

Also, PBMRs should be able to extract several times as much energy from each ton of fuel — which means less radioactive waste.”

Wouldn't it be great to see a country like Australia equip itself with an adequate number of these PBMRs to power desalination plants all along the Australian coastline and to power a national maglev rail system.

You might be interested in the newish field of clean burn coal technology. There are coal fired stations being converted to this technology at present.(short term trial). When proved this is likely to be retrofitted to existing coal powered power stations and incorporated in newly built ones.

Http://www.csenergy.com.au/research_and_development/oxy_fuel.asp

As simply as I can put it. The co2 produced during the burning of coal (c14) is extracted liquefied then pumped back underground. Basically putting the carbon back where it came from.

There is sufficient coal reserves in the world to supply our power needs for thousands of years, even with the lower efficiency that clean burn technology requires.

Просто ще одна записка. Both coal and uranium are finite resources while both will solve the power needs for now another solution will eventually be needed. Neither can be replenished at the rate that we are using them. Clean coal technology can produce virtually no co2 emissions , like nuclear power. The bigger advantage is that the waste does not stay as toxic as long.

Electric trains are considered to produce co2 base on the fact that they draw power from the grid. Of course if there where no co2 producing power plants in the grid then electric trains could not be considered co2 producers. Either way I agree that electric train transport is far cleaner than internal combustion and should be developed world wide.

Томас просить ...

Do you support nuclear energy? Why or why not?

I personally support it.
Because:
Here in Australia, we have a lot of Uranium therefore we can also make money exporting it to other countries.
It does not generate as much Carbon Dioxide as, say, coal which is also a non renewable source.
You can produce a great amount of electricity in a single plant.

But I am not ignoring the fact that nuclear energy is, like everything else, not perfect.
The storage of the waste is an issue, and so is the fact that it is a risky operation.

But if we set the waste problem aside for a moment, the risky operation thing is really not of a great deal.
I mean if you look at everyday life, there is a greater chance of people dying in car crashes (something you do almost everyday is ride in a car) than being killed by the meltdown/accidents of a nuclear plant.

Even though Uranium is not renewable and it will only be available for maximum 100 years, I still think it is a better option compared to coal etc, because it really makes a difference to the emission of Carbon Dioxide.

Share your opinions please and give reasons. :)
@little
I understand where you're coming from, but in comparison to coal, which would you choose?
I myself would prefer if we used wind power or solar power because they are risk-free renewable sources but right now we are relying on coal mostly.

It is producing a LOT of Carbon Dioxide which is contributing towards global warming.

Are Fuel Cells a false economy?

Все, здається, стає дуже роздутими до про нібито водню революція, яка не за горами. Паливних елементах автомобілів, ми обіцяли, буде на 100% тільки з водою в якості побічного продукту. Нам кажуть, що паливні елементи збираються влади все, від автомобілів до ноутбуків.

Хто-небудь ще бачить проблем з цією пропозицією? По-перше, водень є надзвичайно летючий газ, щоб заповнити автомобілів і т.д. з ним буде набагато небезпечніше, ніж заповнити їх з бензином. Крім того, якщо автомобіль повний збій водню і розрив резервуара, все це вибухне при перших ознаках іскри.

По-друге, водень не зустрічається у великих quanities природно, у нас є для його виробництва. Для цього потрібна енергія, і, звичайно, ця енергія просто збирається приїхати в результаті спалювання викопного палива більше на електростанціях. І якщо цього не станеться, якщо ми створили поновлюваних енергетичної інфраструктури, чому ми навіть не потрібно водню? всі (у тому числі транспортні засоби і т.д.) може бути просто підключений до електромережі ...

Експерт відповідей:

Ефективність паливних елементів до мотор перетворення енергії, безсумнівно, набагато більше, ніж у двигунів внутрішнього згоряння і парових двигунів. Вартість системи паливних елементів також безперечно, набагато більше, ніж у СК або парові двигуни.

Від бачення інженер:
"Багато автомобільні компанії почати паливі випробувальної камери, щоб показати людям останню технологію паливних елементів краю. Хорошим прикладом є Daimler Chrysler NECAR. Останній NECAR є NECAR 5. 4 червня 2002 NECAR 5 завершила 16-денний історичний шлях від Сан-Франциско до Вашингтона, округ Колумбія Це був перший в історії спроба вбити автомобіля на паливних елементах на території США ".

З Нью-Йорка, Нью-Йорка в Сан-Франциско, Каліфорнія, становить близько 2930 миль. При середній швидкості 50 миль / год і середній день водіння 10:00. (500 миль / так), це повинно Thip 6 днів їхати у відносному комфорті.
Автомобіля на паливних елементах середньому 184 миль / так, тому значний час має бути витрачено на просування по службі, або автомобіль був болісно повільним даний реальних умовах руху. Ви можете досягти цього середньому з Model T.

Виробництво водню як палива великі масштаби неймовірно дорогим та неефективним використанням сучасних технологій. Найпопулярнішим пропозицією є скорочення вуглеводневих палив, який триває з тими ж проблемами забруднення ми маємо сьогодні, хоч і легше мати справу. Оксиди вуглецю, азоту, сірки та інших забруднюючих речовин повинно бути видалено, і безпечно утилізувати. Щоб бути ефективною, водню повинні бути стислі і зберігаються в балони високого тиску, потім поширюється на «АЗС». Ця технологія існує, і необхідності бути тільки витрачаються. Небезпека циліндрів H2 газ не більше, ніж, створюваних існуючими LPG (пропан або бутан) або скрапленого природного газу (метану) танків, а насправді набагато менша від тієї, яка забезпечується наполовину повний бензобак.

В кінці кінців ми будемо вдаватися до electrolosys води для отримання водню. Наш вибір джерел енергії буде ядерної, сонячної, вітрової, геотермальної та припливів. З них тільки ядерні має ніякої надії на забезпечення необхідної енергії без непоправного руйнування нашої екосистеми. Будемо сподіватися, що до того часу ми досягнемо цього перевалу ми освоїли керованих термоядерних реакцій.

Повністю електричні транспортні засоби є неприйнятними, оскільки вони обмежені в дальності, швидкості та витривалості. Гібриди створюються, і випробування транспортних засобів отримали широке визнання (один випробуваний відмовився віддати свій транспортний засіб після випробування.).

What did we spend the money on .

Bridges to nowhere , renaming post offices , private airports , Fema trailers that sit empty rotting away and rent on storage space to store donated goods for relief efforts that should have been dispersed to hurricane victims .

make it simple for me?

Hydroelectricity is produced by hydropower. Hydropower aka hydraulic power means the force or energy of moving water. It is a renewable source of energy produces no waste and carbon dioxide which helps greenhouse gases (gases present in the atmosphere which reduce the loss of heat). Hydroelectricity comes from the potential energy of dammed water driving a water turbine (engine that takes energy from moving water) and generator (a device that converts mechanical energy to electrical energy ). The energy extracted from the water depends on the volume and the difference in height between the source and the water's outflow. This height difference is called the head. Pumped storage hydroelectricity produces electricity to supply high peak demands by moving water between reservoirs (a place or hollow vessel where something (usually liquid) is kept in reserve, for later use) at different elevations. At times of low electrical demand, excess generation capacity is used to pump water into the higher reservoir. When there is higher demand, water is released back into the lower reservoir through a turbine.

Експерт відповідей:

There's a Hydro-electric Power Plant in North Wales, UK That does more or less what your write-up says.
There are 3 huge water turbines taking the water from a dam 600 feet above the Plant to drive their respective generators.
On leaving the turbines, the water flows to another lake just below the plant.
During the Day (6.0am to 8.0pm), the generators are producing power to the National Grid at Peak Cost to the consumers.
During the night, when electricicty costs are much less, the generators are converted to motors and their rotation reversed. The turbines are lined up in series. The system is started up, the turbines become pumps and, the water from the lower lake is pumped back to the higher lake overnight.

So what, if you did cut and paste the text you have.
I have visited the above installation (I'ma Brit), and it's nothing short of an amazing place to visit.
The whole turbine generation plant with all facilities are built into a mountain…A bit 'James Bond-ish' but, it's a fact…a fantastic set-up.

Linda asks…

give comment about RECYCLING FACTS AND BENEFITs?

Everyone today has heard of how important it is to recycle and most cities offer a recycling program, but what exactly is recycling and how beneficial is it really to us and the environment?

What are the recycling facts and benefits?
Recycling is the process of turning one products useful parts into a new product; this is done to conserve on the consumption of resources, energy and space used in landfills.
By recycling 1 plastic bottle not only saves anywhere from 100 to 1000 years in the landfill but also saves the environment from the emissions in producing new bottles as well as the oil used to produce that bottle.
For every 1 ton of plastic that is recycled we save the equivalent of 2 people's energy use for 1 year, the amount of water used by 1 person in 2 month's time and almost 2000 pounds of oil.
Approximately 60% of our rubbish thrown away today could be recycled. A survey was done and 9 out of 10 people surveyed said they would recycle more if it was easier.

Odd as it seems there are many people who do not realize that plastic bottles our water comes in is made out of oil. This is the same oil that is used to make gasoline. It's the same oil that is in such high demand and is not an unlimited resource.
Today the most common products in cities recycling programs are paper products, cardboard, plastic, glass and aluminum.

Taking just a moment to put your newspaper, soda can and glass spaghetti jar in the recycling bin will save everyone years in environmental harm from production of new materials, over crowded landfills and the depletion of our natural resources.
4000 Years

When we do not recycle at least our glass or aluminum we cost the earth in power usage, water and oil usage and landfill usage; glass takes up to 4000 years to decompose in a landfill yet can be recycled indefinitely.

Earn Money
Recycling can be done at home as well as in conjunction with city programs. Many scrap yards pay for scrap metal including the soda cans and soup cans we use every day.

Be Creative
Many useful items can be made from our everyday trash; the cardboard tubes left over from paper towel and toilet paper can make useful storage containers for our extra extension cords and prevents a tangled mess in the Christmas lights. If your going to throw these out don't just throw it in the rubbish bin, put it the recycling bin.

Baby jars can become snow globes the kids can make and give as gifts, old Christmas cards can become new hand made cards and a glass or plastic bottle along with some clear oil and food coloring and a few other common household items can become a groovy lava lamp!
The possibilities are endless and instructions can be found in books and on the internet.

Recycling is a very environmentally green activity; however, there are ways that you can make it greener as well as building a strong beginning if you do not currently recycle.
Many people beginning a recycling program look around and wonder what they can put in the recycling bin; there is so much information available on this site, so don't panic.
By reusing your recycled storage containers you save on the environmental impact as well. Paper and plastic bags are good for recycling storage ; however, a plastic reusable bin is even better.

Spread The Word
Share what you know. If you notice abundant trash in your neighborhood start spreading the word and your experience with recycling and if there isn't already one in place strive to get a city recycling pick up program started.

The fact is many of our resources as well as our Earth is not renewable and we have to start taking control of our selves beginning with the world we live in.

Global warming is no longer viewed as a theory by scientists and has sadly become a fact. The change needed must be in your actions today in order to ensure a bright (not too hot) tomorrow.

This is nothing but a scam to eventually steal all of your money and commit identity theft with your information. They will ask you to send a copy of your passport to some “agency” to process the visa, then ask for money. Then ask for more money for another certificate. Then more money then more until you finally wake up and realise it's been a scam all the time

Delete this or report it to whichever agency in your country deals with internet crime

A major global company like HP is NEVER going to offer a job over the internet. If you were not flown to the UK for an interview at their head office in Bristol (they aren't in London) then the job doesn't exist. A company cannot get a visa for a person they've never met in person. That's one of the requirements the company has to prove – that they have either flown to meet you or flown you in to meet them for at least 2 interviews before they can offer you the job and sponsor a visa

Renewable energy ideal – wind turbine on wheels to capture hurricane power?

Is it possible to get a giant mobile wind turbine on wheels that can be placed in hurricanes in order to collect large amounts of energy ?

For example, how about a very rugged turbine(like propeller you would use for planes going 500 MPH) and a energy storage device that converts aluminum oxide to aluminum(high energy potential material/released energy = thermite reaction) for example. With hydrogen, you waste energy compressing… so preferrably some energy conversion system that gives solids or liquids. Then just pump the fuel to anywhere and convert it to electricity.

YEAH???
Of course you take the wheels off and lock in down once on location… materials for construction can be very cheap I think if they REALLY REALLY tried to build using already made parts.

Експерт відповідей:

It is not possible to make strong enough and big enough turbines that are also portable, and any way, hurricanes do not happen often enough. And just imagine the amount of fuel and number of workers and the time that would be needed to move these giant machines! Far better to build thousands of turbines permanently installed in locations that see moderately strong winds most of the year. Winds strong enough to make lots of power but not so strong as to damage the turbines. Winds than blow almost every day and not only one or two days out of the year. That is being done already.

And your energy storage ideas sound like they would store very little energy and require a great deal of trouble to implement.

which type of plant is the Turkey Point Nuclear Power Plant in Homestead Florida?

is it either BWR or PWR?

Експерт відповідей:

Turkey Point nuclear plant is a PWR ( Pressurized Water Reactor ) facility but on June 30th 2009 they submitted an application to build 2 1,550-MWe ESBWR ( Economic Simplified Boiling Water Reactors ) so upon completion of those reactors around 2017. Turkey River would be both a pressurized water reactor ( PWR ) and a boiling water reactor ( BWR )

Бетті запитує ...

Are we going to see any new nuclear power plants built in the near future?

In the most recent example of staggeringly expensive new nuclear plants ,

“The Ontario government put its nuclear power plans on hold last month because the bid from Atomic Energy of Canada Ltd., the only “compliant” one received, was more than three times higher than what the province expected to pay [at $13 billion per reactor].

It means a single project would have wiped out the province's nuclear - power expansion budget for the next 20 years, leaving no money for at least two more multibillion-dollar refurbishment projects.”

“Much of the dramatic price increase relates to the cost of labour and materials, which have skyrocketed over the past few years. Nuclear suppliers and their investors also have less tolerance for risk.”

http://www.thestar.com/comment/columnists/article/665644

Similarly, Turkey couldn't get any bids below 21 cents per kWh for a new nuke (their average energy cost is currently under 8 cents per kWh).

http://www.todayszaman.com/tz-web/detaylar.do?load=detay&link=164556&bolum=105

A new nuke in Finland went over budget by more than $2 billion (50% over the original estimate) and 3 years over schedule.

http://www.reuters.com/article/rbssIndustryMaterialsUtilitiesNews/idUSLS56745220080828

In the USA new nuclear energy is on track to cost 15¢ to 20¢ per kilowatt-hour. And no nuclear plant has ever been completed on budget.

http://www.time.com/time/printout/0,8816,1869203,00.html

Florida Power and Light concluded that two new units totaling 2,200 megawatts would cost $12 billion to $18 billion.

Progress Energy informed state regulators that the twin 1,100-megawatt plants it intends to build in Florida would cost $14 billion, which “triples estimates the utility offered little more than a year ago.” and its cost estimates are “nonbinding” and “subject to change over time.”

http://climateprogress.org/2008/06/13/ nuclear - power -part-2-the-price-is-not-right/

With these incredibly high costs for new nuclear power plants all over the world, do you think we'll see any new nukes built in the near future?

Експерт відповідей:

I think it depends on how much the federal government subsidizes it. The US Has already put out over $100 billion (Time article). The rational originally was to promote a fledgling industry. But the nuclear 'wings' still don't support its weight.
And that's not counting the cost of permanent disposal of nuclear waste, which is very expensive. The Yucca Mountain facility is on hold, because Nevadans don't want the waste 'in their backyard'. So it's kept a lot closer to you than Yucca Mountain is to most Nevadans.
Who computes the end-to-end cost of nuclear fuel? It takes a lot of oil to produce the fuel ready to go into the reactor, and leaves behind a mess of radioactive tailings.
Three Mile Island accident discouraged banks from financing industry. The costs overruns and political uproars in the 70s and 80s..
So unless the idea of Uncle Sam subsidizing power plants heavily gets traction, I don't think there will nuclear plants built here.
Oh, and Germany just had an accident (Krummel), including core damage.

Why don't the proponents of global warming support nuclear power?

This has always puzzled me, because most proponents of global warming are skeptical because they're afraid of the lower cost and efficiency of nuclear power .

But you would think if that were the case, they would mostly favor the change to lower the consumption of cheap fossil fuels such as coal and natural gas. Yet most proponents seem to wholeheartedly resist an increased use of nuclear power .

This seems to contradict their ecological motivations, because new nuclear power is extremely efficient and clean. One of the few new nuclear power plants proposed to be built in the US in the last 30 years – in San Antonio – was originally estimated to cost $13 billion for 2 reactors. The price tag just went up another $4 billion due to unions and unfounded EPA regulations.

http://www.mysanantonio.com/news/ Nuclear

The same story can be applied to proposed nuclear plants in Florida , North Carolina, and abroad in Canada and Finland. Due mainly to the EPA and the proponents of global warming, nuclear power is highly suppressed viable alternative.

Yet we constantly hear questions from proponents of global warming about why non-believers don't support algore and the church of global warming more strongly.

What's the deal? Do they not understand the reality of clean, efficient nuclear power ? Do they resist it just because non-believers know nuclear power is better than coal and natural gas? Are they just parroting what they hear from the liberal media and political websites?

Експерт відповідей:

They're afraid that a nuclear power plant will be built where they can see it, and they don't look very good. Obviously, the solution is to build them in AGW skeptic's backyard, which alarmists see as fair. However, the rest of us don't agree with the alarmists, so they feel the need to eliminate all the nuclear power plants, as not everyone agrees with alarmists over them.

You all think I'm joking, don't you? Ted Kennedy refused to have a wind farm built near his property, because it would disrupt his view. Same thing with liberal Sen. John Warner, who tried to bar the Army Corps of Engineers from permitting offshore windfarms, as he and his relatives all live on the coast. Clearly, all the alternative power plants belong in the west, so that they can disrupt the view of people that don't matter (particularly conservatives).

Just imagine what it'd be like if you replaced the windmills with a massive nuclear power plant belching clouds of steam.

Why do global warming 'skeptics' support nuclear power so strongly?

This has always puzzled me, because most AGW deniers are 'skeptics' because they're afraid of the economic costs of carbon regulation.

But you would think if that were the case, they would mostly favor the status quo of relying on cheap fossil fuels such as coal and natural gas. Yet most 'skeptics' seem to wholeheartedly support an increased use of nuclear power .

The same story can be applied to proposed nuclear plants in Florida , North Carolina, and abroad in Canada and Finland. Due mainly to increased construction costs, nuclear power is an expensive alternative.

Yet we constantly hear questions from deniers about why “alarmists” don't support nuclear power more strongly.

What's the deal? Do they not understand the reality of nuclear costs? Do they support it just because environmentalists used to object to nuclear power ? Are they just parrotting what they hear from the right-wing media?
Looks like it's indeed a combination of my suspicions.

1) They're purely anti-environmentalists.
2) They're purely anti-liberal, and view renewable energy as “liberal” and nuclear as “conservative”.
3) They're stuck in the 1970s and think nuclear power is still cheap.

Or some combination of the three.

Експерт відповідей:

I think history plays a role in this. Most global warming deniers are on the political right. In the 1970′s-1980′s, many environmentalists had concerns over nuclear power, which eventually lead to stricter regulation. Environmentalists had been supporting renewable energy. Many on the right were angered that environmentalists were successful at influencing policy and blamed them for slow growth of nuclear power, even though much of the reason for that was rising nuclear costs, and plunging fossil fuel prices. So US Republicans believe they “own” nuclear power and see renewables “owned” by liberals. Their support for nukes is like cheering for a team. The fact that nuclear power is quite expensive eludes them. They want to push nuclear power so they can feel like they finally beat those pesky environmentalists that thwarted them in the 1970′s. In other words, they are living too much in the past.

Nuclear power is an effective global warming solution and independent of that, has much fewer environmental problems than coal. If they can get the costs down and economically compete with renewables such that they are clearly and consistently cheaper (nukes no doubt have more environmental and national security costs than renewables), more “power” to them.

Sharon asks…

How can we rely on increased nuclear power production given its cost?

Florida Power & Light estimated that building a new nuclear plant in that state would cost $12-18 billion. A new study concluded that generation costs from a new nuclear power plant would cost 25-30 cents per kWh – three times the current average US electrical rates. A June 2008 report by Moody's Investor Services Global Credit Research concluded that any utility engaging in the risky venture of building a new nuclear power plant would experience a severe decline in its credit rating.

http://climateprogress.org/2009/01/07/ nuclear - power - plants -troubled-assests-credit-risk/#more-4585

Now I want to point out that I'm not suggesting we shut down all nuclear plants and never use nuclear power again. However, many people seem to feel that nuclear power is a silver bullet which will solve all our energy problems. Given the costs and risks of new nuclear plants , it seems more like a diamond-encrusted platinum bullet to me.

So how can we rely on increased nuclear power production to solve our energy problems given its cost and risks?

Why is the GOP pushing for new nuclear power?

“Republicans say, build 100 new nuclear power plants during the next twenty years”

http://www.gop.com/News/NewsRead.aspx?Guid=92504368-37ec-4d4e-94bb-9edc4fc33250

But as they push for a massive number of new nuclear plants , this is what's happening around the world.

Finland: “After four years of construction and thousands of defects and deficiencies, the reactor's 3 billion euro price tag, about $4.2 billion, has climbed at least 50 percent. And while the reactor was originally meant to be completed this summer, Areva, the French company building it, and the utility that ordered it, are no longer willing to make certain predictions on when it will go online.”

Turkey: “The only company bidding…offered a price of 21.16 cents per kilowatt-hour (kWh). Current electricity prices in the country vary between 4 cents and 14 cents per kWh.”

http://www.todayszaman.com/tz-web/detaylar.do?load=detay&link=164556&bolum=105

Even here in the USA, in Florida : “Progress Energy offered its revised estimate Tuesday: $14-billion for two new nuclear reactors…The utility said its 200-mile, 10-county transmission project will cost $3-billion more. The total cost triples estimates the utility offered little more than a year ago.”

http://www.tampabay.com/news/business/energy/article414653.ece

Idaho: “Consumers expect reasonably priced energy, and the company's due diligence process has led to the conclusion that it does not make economic sense to pursue the project at this time,” Bill Fehrman, President of MidAmerican Nuclear Energy Co, said in the letter to Payette County residents.

http://www.reuters.com/article/companyNews/idUSN2957446620080129

The list goes on. Why does the GOP want 100 new nuclear power plants when currently they're so expensive and having so little success in the USA and around the world?

Експерт відповідей:

Well, call me a crazy conspiracy theorist, but I think it has something to do with the centralization of power. Read whatever you like into that statement. What other possible explanation can there be for their vehement opposition to distributed [anything]?

We could actually have clean efficient nuclear power with gen IV designs that can actually burn nuclear “waste”. But this type of nuclear infrastructure would turn nuclear power into a kind of public trust – the last thing they want.

When you can't centralize and control and take all the profits and funnel them upwards – they want nothing to do with it. More than that, they want to quash distributed infrastructure of any sort, lest the little people get the idea that they can have some measure of control over their own lives and destiny. I think people are starting to wake up to what happened in the last century. I think it's telling that the new administration gave more of GM to the unions than to the bondholders. It's a beginning of a return to some sort of balance.

I like your explanation from before – nuclear is pointless when renewables (even centralized renewables) are cheaper. However, if we don't do demand management in a big way, like an Apollo program that cuts energy use in half in 10 years, the demand growth for energy coupled with realization that carbon is destroying the climate may make nuclear inevitable – because without demand management renewables can't satisfy the load. Or can they?

Light water reactors are one of our most dangerous, inefficient, wasteful and unsustainable technologies. We mine the uranium at tremendous (social and environmental) cost. We only have enough uranium for 70 years anyway. We use it once leaving 99% of the energy behind turning it into a 100,000 year nightmare of highly radioactive, highly toxic waste. All the light water reactor waste ever created is still there, in holding ponds, at the power plants where it was created.

“…some form of molten-salt thorium breeder could be the most efficient well-developed energy source known, whether measured by cost per kW, capital cost or social costs.”

But we don't do it. The party of dumb wants more light water reactors. Чому? See above and some of the other salient answers.

Why Not Nuclear Reactors if So Much Concern about Environment?

In California, we have one nuclear reactor, on half the time. We still have coal burning power plants . How many tens of thousands of kids and adults have to get asthma before CLEAN nuclear power is established? Florida has 5, their rates are 1/4 of California. Even tiny Switzerland has 5.
There have never been any nuclear 'accident's in the United States. No one was ever injured, no plant or animal of any kind was injured. We had a scare only with Three Mile Island. Russia had catastrophes with poorly designed reactors.
Nuclear reactors have zero emissions unlike even 'clean' natural gas or so called 'clean' coal plants .

Because the world is full of really uninformed, and sadly stupid, people. If they pulled their head out of the sand and really found out how safe and clean and cost effective nuclear is we would have lots.
By the way, it is possible to have clean coal plants. We need them also.
We need a diversity of nuke, coal, wind, water, solar. Each has it's place. We need to educate people that 3-mile island was a success! The operators did every stupid thing possible and the controls still shut down without anyone geting hurt, miniscule radiation leakage and only damage to one reactor. Modern ones are even safer, cheaper and more efficient. Media “hyped” Chernobal. It was a cheap plant put up by stupid government. Had no “containment” building (such as the one at 3-mile island). No wonder it was a disaster.
Simple answer. Media has talked “sheep” in this country into believeing nuke is unsafe. Blame Jane Fonda for one more thing “meltdown”. It was only a MOVIE folks, not real life!

Lisa asks…

lightning arresters and storage devices?

is there a way we could use lightning arresters and storage devices to store energy from lightning and use it as a renewable source of electricity?

Експерт відповідей:

Fortunately, there is not a terribly large amount of energy contained in a lightning discharge.

Consider, for instance, the voltage, current, and time characteristics of a 'standard' lightning waveform.
This standard waveform is what electrical equipment is designed to withstand, so it actually uses conservative (overly large) values.

On a 35 kV ac distribution system, a 20 kA lightning surge (20 kA is larger than 90% of all lightning discharge currents) would produce about 100 kV crest. The typical waveform has an 8 microsecond risetime and 20 microsecond tail.

Thus, the total energy is not more than (20 000 A) x (100 000 V) x (28 x10^-6 seconds) = 56 000 J.

56 kJ corresponds to 15.56 Wh (Watt-hours). Considering the amount of equipment involved in somehow capturing the energy of the charged cloud-to-ground capacitor, this just isn't enough energy to make it worthwhile.

Lizzie asks…

Why not nuclear the same as France?

I've read many questions and answers about power generation and how the US energy crisis could be solved by renewable resources such as wind or solar cells. While wind, solar cells, hydro, landfill gas and other types of renewable generation all have their place in an overall mix, due to their variability and diffuse nature, none are a viable source of reliable base load power. I emphasis the importance of reliability since there are no practical methods of storing energy that do not have a steep price in efficiency.

The first method of effectively increasing the supply of renewable energy is to use less. Next, if and until fusion power becomes a reality, the only other answer, and I know there will weeping, arm flailing and talk of doomsday, is the use of fail safe nuclear reactors (they will shut down before melting down) with fuel reprocessing to alleviate the spent waste storage problem. 80% of France's power is nuclear. What do they know that we don't?

I don't understand most of the technical things that go into the production of energy, but it only takes common sense to understand that if we can make electricity from something that doesn't have to be forced from the ground and doesn't release large amounts of pollution it has to be better than what we are doing now.

Need information on energy?

I am doing a project on energy . It consists of 12 different types of energies. I just need information on some of them because they are hard to find. They are:

1) Ethanol/Methanol
2) Bio-mass
3)Lithium Ion Battery
4) Pumped storage reservoirs
5) Geothermal

The information I need on them are:

A) Is it efficient?
B) Is it renewable , why or why not?
c) Is it reusable
d) can it be used anywhere?
e) where is it best used?

*Thanks for your help!!

I can tell you about Geothermal Energy!
Geothermal energy is pretty much energy inside the earth.
Steam and hot water is geothermal energy.
What happens is the steam/hot water is usually located in a place called a geothermal reservoir, which is a very hot area underground ranging from 300-700 degrees Fahrenheit.
The steam/hot water is sucked through pipes and into a turbine. The steam/hot water causes the curved vanes of the turbine to spin, thus creating energy. That energy is not fully developed though. It goes through a generator, and then the power can be used to heat homes and other buildings.

For ethanol, use these websites:

For Bio-Mass energy, use this:

Helen asks…

Are McCain/Palin supporters Naive or Oblivious?

I just don't understand?, republicans whine and complain when things go wrong; http://en.wikipedia.org/wiki/Approval_rating

Then all of a sudden their republican presidential nominee chooses a female as his running mate for vice presidency. They forget all about the major issues they so annoyingly complained about over the past few years. Health Care, Education, National Security, Immigration, Abortion, Same-Sex Marriage, Social Security, and the Economy.

Which of these do John McCain and George W Bush disagree about OH YEAH!, none:

http://www.nytimes.com/interactive/2008/06/17/us/politics/20080617_POLICY_GRAPHIC.html

Sure they do disagree on a few issues but just answer me this in the past 100 years(and not in the last 20 to 30 or so years) which of these: Climate Change, Energy and Oil, Renewable Energy , Interrogation Tactics, and Arms Control. Can you say was brought up as an important issue related to the american people?. I would have to say NONE!.

Is Obama the answer I don't know and i don't really care. Is McCain the solution to our problems sure, if hell freezes over.
Jeez, are you serious when you don't see proof you complain. “where are you facts blah blah blah”. I give you actual facts from reliable sources and it's not enough that's amazing how insanely stuborn you people can be.
I don't follow politics but it's laughable how easy it is to correct some of you like ricky there,

McCain/Palin supporters are those that believe in the American dream…

Do you honestly think republicans are the only one's who dream of that, what person in the world doesn't believe in the american dream; it's what most of us dream of it's what we strive for. Do

Those supporteres haven't forgotten about health care and education…

How are thes not your opinions?, it's completely contradictory bush and McCain agree on the same policy. FOR CHRIST SAKE AHHH!!!.

They haven't forgotten about National Security….

The last attack on American soil before 9/11 occurred 60 years prior, how is that any different than the past 7 years?.

They haven't forgotten about immigration, because they want the illegals to stay out and welcome the documented….
This is why republicans disgust me this wonderful country you love so much was founded on a single basis, Give us your tired, your poor, your huddled masses. We are a nation of immigrants how we've deluded ourselves into believing that were not natives of this country is beyond any kind of normal comprehension.

They haven't forgotten about abortion. They remember that, “Thou shalt not kill.” They haven't forgotten about same-sex marriage, they ignore it because it's not a natural union.

Once again how does this not differ from what I said about health and education

They haven't forgotten about Social Security. They believe that putting money into the people's pockets and letting them invest it in private funds is better than having government do it for them. Finally, the economy is in better shape than it was in the Clinton years, but a Democratic Congress has made it difficult for the President these past two years.
Why would anyone in the past 100 years bring up climate change, energy and oil, renewable energy , interrogation tactics, or arms control? Global warming wasn'ta concern. Energy and oil were what made the Rockefellers rich. Renewable energy didn't exist. Interrogation tactics included beating the bejesus out of someone until the talked. And arms control was I dare you to pry this gun from my cold dead fingers.
EXACTLY!, does this person have a brain? I clearly stated that.

Is Obama the answer? No. Is McCain? That's the way I'm voting.

How does this final statement even make sense?.

Експерт відповідей:

Look at this “we haven't be attacked in 8 years”. No, seriously…read that again. Maybe a couple times until it actually sinks in. It's only been 8 years. It took over 200 for the 1st attack. Are you people actually that frigging stupid? Honestly, you act like 8 years is long. 8 years is nothing. We ARE going to get attacked again. We figured this right after the attacks. When did you think we were going to get attacked, the next day? We are no safer now than we were 9/10/01. If you believe that, you are ignorant and I hope that it's bliss. But, it's not true. We are no safer now than 9/10/01.

Is The government handing out nearly $2 billion for new solar plants to create jobs Bad?

Obama hands out $2 billion for new solar plants, says money will help create thousands of jobs

The government is handing out nearly $2 billion for new solar plants that President Barack Obama says will create thousands of jobs and increase the use of renewable energy sources.

Obama announced the initiative in his weekly radio and online address Saturday, saying the money is part of his plan to bring new industries to the US

“We're going to keep competing aggressively to make sure the jobs and industries of the future are taking root right here in America,” Obama said.

The Obama administration says those projects will create more than 2,000 construction jobs and 1,500 permanent jobs.

Obama said that while it may take years to bring back all the jobs lost during the recession, the economy is moving in a positive direction.

The unemployment rate dropped to 9.5 percent.

Obama has said that to bring the nation's economy back from the brink of a depression, it was necessary to add to the country's debt in the short term.

Everyone is talking about CUT SPENDING. But Is this SPENDING bad?

According to conservatives, yes. Because Obama did it. If anyone else had done it, it would have been fine.

Why are there so many social problems in the richest country in the world?

To name but a few, the USA scores lowly in all of the following compared to countries like Japan or Scandinavia (and most of western Europe to a lesser extent):

1) Crime
2) Teenage pregnancy
3) Health/life expectancy
4) Poverty and low income
5) Long working hours culture / less paid hoilday
6) Educational achievement/literacy rates
7) Obesity 8) Environmental pollution eg CO2 per capita, recycling
9) Public transport and renewable energy
by richest country i just meant total not per capita

http://en.wikipedia.org/wiki/List_of_countries_by_GDP_(nominal)

I don' think you can argue over population is the cause of these problems when the countries that perform best are generally more densely populated (japan and western europe) than the usa.

I would suggest government has a big role to play in most of these as many of them are linked – particularly to inequality, education, healthcare and environmental regulation. With the exception of japan, most of western europe has a bigger public sector than the usa.
Personally I would suggest higher taxes on fuel, higher taxes for the rich, less defence spending, and more education, healthcare and public transport spending.

Експерт відповідей:

Rich country doesn't always equate rich people. In other words, just because a country is rich, it doesn't mean the riches are trickled down to the masses.

Government and corporate officials are very rich and can afford the best in healthcare, education, environment.

Over the last 20 years the US Has become less “government of the people, by the people” and more “government of the corporations and for the corporations”

Americans do not have the same resolve as Americans from say world war 2.

Linda asks…

Can someone help me with my DIY residential solar project?

I'm new to the topic of renewable energy with solar panels. I've been doing some research and I think I have a general idea of what is required in a DIY scenario. However, most of the guides have very limited information regarding the use of an enclosure, box, etc. The information that I have found usually points to some home-made enclosure or leaving the batteries exposed. I'd rather not do that if possible.

The closest I have gotten is the Xantrex PH-1800, but it is not officially offered to the general public, so their website does not have any documentation posted on this. Here is some info on my scenario and the type of system I'd like to set up:

Portable:
I live in a house with plenty of space in the yard, and a spare bedroom, however, I don't plan on living here for much longer, so I'd like a small enough system that can be moved to the next house (possibly apartment) I move to.
Here's a picture of one that I found, although again, this one is only sold in bulk:

http://image.made-in-china.com/6f3j00lCf…

I'd like the container to allow for battery replacement. If it's a small container/enclosure, I'd like for it to be scalable so that I can add more batteries down the line if need be. The xantrex enclosure seems to offer that feature, but I'm not sure if that might be too advanced for me. I have a strong tech background, but limited electrical.

Scalable:
To begin with, I would like to simply power just an AC for 4hrs that uses 600 watts. If I'm calculating this right, then I would need 6 deep marine cycle batteries so that I don't drain them past 50%. I would also need an inverter rated at 600watt minimum.

Going back to the enclosure, ideally, the enclosure would have hookups that allow for adding/removing batteries without changing the solar panels. If the charging speed slows down, that's not a big deal for my scenario. Is there a such thing out there?

These requirements are not set in stone, so if I missed anything, feel free to subsititute numbers where necessary. The most important feature I'm interested in is scalability so that I don't have to throw away components down the line. I'd rather buy a 1000watt inverter now even if I would only use 600watts, assuming this doesn't produce another inefficiency. If it does, please let me know.
Update:
Thanks for the feedback. However, does anyone have information regarding a container that does not involve some kind of DIY process?

Also, since this is more of a starter project for me, I wouldn't be planning on using the AC and charging the batteries at the same time. In fact, I generally get home late from work and might only use this during the weekend.

Also, does higher wattage from the solar panels mean faster charging? I was under the impression that the controller's job is to pretty much take whatever electricity is coming from the solar panel and then “standardize it” to whatever the battery can handle, kind of like a funnel so to speak.

One other related question, would this change if I were to connect say 6 batteries in parallel or woudl it still require the same amount of wattage for the charging process?

Експерт відповідей:

Your 600 watt AC will need about 1800 watts of power for start-up. This surge is only about 2-3 seconds. Then the running watts at 600 is okay. These motors take a lot of extra power during start-up. So your inverter needs to be able to accommodate that surge. The batteries can fill in that surge, so your solar panels don't have to be that big in that sense.

But here's the kicker. You'll probably use your AC during the day time, the same time your solar panels are charging the batteries. The battery system would normally provide power during the night or cloudy days when the solar panels are not effective. The solar panels would normally provide power to the AC and recharge the batteries during the daytime when they are effective. The solar panels should be able to provide a minimum of 2400 watts during the time they are effective. They can charge the batteries when the AC isn't running. Depending upon where you live, solar panels may be effective for about 5-6 hrs per day unless you can orient the panels directly toward the sun as the earth rotates on its axis.

120 vac @ 5 amps = 600 watts
12 vdc @ 50 amps = 600 watts. You'll need solar panels that can provide 50 amps just to run the AC during the day. Then additional capacity of about 40 amps to recharge the batteries. 40 amps @ 12 vdc = 480 watts for 5 hrs will give you 2400 watts

So, unless my numbers are wrong, your solar system may have to be as much as 100 amps at 12 vdc = 1200 watts in order to run your AC off grid and still recharge the batteries.

Am I a Democrat or Republican?

Ok. I'm 13, and basically am just trying to figure out the political party my views fit in with best. I think I'ma Democrat, and that's what most quizzes I've taken have said, but I want a larger amount of people to take a look at it. Without further ado, here are my views on certain subjects.

I generally think that abortion is wrong, but I would NEVER take away a woman's right to choose.
I believe that Obamacare is a good thing.
I believe in welfare programs.
Gay marriage should definitely be legalized.
Affirmative action should be perfected. I believe that someone more qualified should have the job, not the minority.
I believe in a progressive tax rate. The highest bracket should be at almost 50%, with the lowest near 0%.
As for prayer in schools, I think that a student should have the right to be excused from class if he/she wants to pray, but no school should ever mandate prayer.
I would like us to move towards more renewable energy and hybrid cars.
I believe in an absolute separation of church and state. I don't even like it when candidates say, “God bless this land,” at the end of a speech.
Thanks for all the answers. Oh, and to the person talking about socialism and evolution, I am not a socialist, and I believe in evolution. We are humans because of a series of mutations over millions of years, NOT because God created a bunch of different animals.

How are todays landfills for economical and efficient. What would happen if America didn't have landfills?

-what items can be recycled (as in when you take your recycling bins curbside) what goes to landfill? I know pizza boxes, hangers, paint cans, anything contaminated either with food or chemicals can't be… I don't think. Why is it better to put it in the landfill?

I've heard if you throw a plastic bottle in the land fill it can last a thousand years?! Is that true. I read there is a new thing called bio-reactor landfills. These types of landfills use moisture as a method to enhance the waste degradation process. Have you heard of a bio-reactor? How does it work?
Studies carried out by EPA have suggested that by operating a landfill as a bio-reactor there is an increase in settlement of the solid waste as well as an enhancement in the methane generation rate of approximately five times that of conventional landfills. Overall, technologies developed under this program can extend the utility of municipal solid waste landfill space and produce a viable source of renewable energy .

I'm looking for information of how landfills today are economical and efficient.

I keep finding a ton of info on recycle, and zero-waste. But everything can't be recycled can it? What happens to those materials/items? What would happen to America if we didn't have landfills.

Експерт відповідей:

Landfills are likely a necessary part of life – at least for the foreseeable future.

You mentioned pizza boxes, things with food on them – these can actually be composted, as opposed to “recycled” or landfilled. There are a growing number of companies that are latching onto this niche – especially in large suburban/urban areas where there is a need/market for such services – and a healthy supply of compostible material. Some government agencies are setting goals for a certain percentage of their waststreams being diverted for composting – significantly reducing the actual trash haul.

Bio reactor landfills do provide a benefit – as in the methane gas they produce which can be collected and utilized.

Someone mentioned planting trees to help stabilize landfill areas – I'd caution against this, as tree roots may penetrate liner layers of the landfill, allowing for unwanted releases or inputs of of percolating liquids.
Grass and small shrubs can hold soil pretty well – hence the standards for maintaining vegetated landfill caps.

What will America/the world be like when humanity runs out of carbon fuel?

By now, most scientists are beginning to realize large scale renewable energy (such as solar, wind, etc) isn't going to be possible (at least not before we run out of carbon based fuels). So, what the hell are we going to do? What will America be like when the people who live in the suburbs don't have the gas to make it to the city? What will New York City be like with sky high food prices and shortages? How will YOU survive the Apocalypse if it comes in your lifetime? We've already passed our peak for oil and natural gas, and with consumption at the rate it is, it is likely we will run out soon or begin to see amazingly high gas prices.

http://en.wikipedia.org/wiki/Hubbert_peak_theory#Natural_gas

You all realize of course that ignoring the problem or saying it probably won't happen won't keep it from happening right?

Експерт відповідей:

The environmental consequences of continuing to use fossil fuels will claim human civilisation before carbon fuels run out completely, assuming that the world continues to consume such energy resources it at its current rate. At the moment, that looks like a pretty safe assumption.

Renewable energy sources are indeed feasible, (http://www.bullfax.com/?q=node-renewable-energy-feasible-group-says) but their implementation would require a gigantic change in the way that the resources of the world are managed, a change that the powers that be are basically not willing to make. By “the powers that be”, I mean the world's most powerful industrialists and corporations.

In any case, I think there are some tough times for the human race coming up this century. Civilisation as we know it may well fall deeper into chaos, famine and war, but perhaps at least some of humanity may be able to survive and eventually see better times. At the moment, most people in the world are just trying to survive day to day, and are unaware that our global society is about to casually walk over the edge of a cliff.

Have you ever gotten 3 estimates to put solar PV on your house w/ power company rebates and a 30% tax credit?

In CA, you can lease a system, for only the cost of your electric bill at today's rates . That certainly affordable. You lock in the rate you pay today, no power rate increases. The system is warranted for 25 years, is connected to the crid and sized so the power company provides your power in bad weather and at night. Or you can buy the system, pay it off in 8-12 years and have free power from then on. Why do people say solar PV is not viable? Solar is more efficient in colder temperature. Voltage increases as temperature goes down. There are a lot of misunderstandings about solar. The federal tax refund, is like tax deductions for mortgage interest, allowable and your right to use. Renewable energy is not Partisan, it's sensible and saves you money. Why not get a few estimate and find out what it really costs, and how it really works?

How to reduce the USA federal budget deficit? A spending freeze, is that really a serious approach?

A serious freeze on 17% of the budget while the big spending items like the military are not frozen? Is that a real serious approach to deficit reduction?

What about returning income tax rates to what they were about 30 years ago or so on the top 1%?

The other issue is …..how does stopping domestic spending help create jobs? I thought it was common knowledget that one way to stimulate spending and therefore the economy is to have public works projects..like road and highway building and repairs, and same for bridges, dams, and other infrastructure? what about the renewable energy type projects they talked so much about during the election campaign of 2008?

Anyone else like me think that the Obama administration seems to have not conviction…no real belief? certainly not belief in the reform rhetoric they were shouting out during last campaign season. Since when is a 59 to 41 majority in the senate a handicap? since when is a huge election victory last election a handicap? And why the heck is Joe Lieberman chairman of anything right now anyway?

I voted for Obama and Democrats last election…….and like many people who did am getting pretty pissed off. Before you Republicans get too excited, yes I am bashing Obama and Democrats, but it will be cold day in hades before a Republican gets my vote…cause they are even worse.

Експерт відповідей:

The military is only $600 billion out of a $3.2 trillion budget. The other $2.6 Trillion is for unconstitutional domestic programs like Medicare, Medicaid, Social Security, etc. Our deficit for the year will be more than $1.4 trillion, so even if you cut the military budget to $0, we would still have an $800 billion deficit.
I don't know you liberals always want to cut the military, when it is a tiny fraction of our spending and it is actually authorized by the Constitution (article 1).

Domestic spending does not create jobs, it just relocates them. Those public works projects are paid for by tax dollars taken out of the community. In other words, the government takes $1 billion in taxes out of 1 community, and then uses that money to build a bridge in the next community over. They didn't create any jobs by doing that, they just moved them from 1 place to another.

You sound like you are making an attempt to be objective, which is more than I can say for most Democrats. However, you are seriously misinformed and need to educate yourself.
Step 1: read the Constitution. Pay special attention to the 9th and 10th amendments.
Step 2: take into consideration how the government works. Everything the government does is done by law, and law is backed by the use of force.

Would you rather live in a society with no money if it was possible?

this is a little hypothecitcal – would you rather live in a world without money? Imagine if we could harness technology to produce our food and housing and basic needs, used 100% renewable energy such as heat from the earths core. Having no money would also change the schooling system, instead of teaching children to pass exams, to earn passage to university, to earn more money, we could school children to be good human beings and inventors.

Do you think this would reduce crime and war in the world or do you think that humans would find something else to fight about?

Beart in mind that poorer areas of cities and towns ALWAYS have higher crime rates than richer areas, and that all wars are fundemently wars to get control of resources which equal, money.

What measures have the UK government taken to reduce CO2 emissions in industrial/transport/retail sectors?

I genuinely do not know.

They have targeted the housing sector heavily; HIPS, Energy Asset Rating and the constant drives for us to have renewable forms of energy and energy efficient light bulbs.

The problem is, energy wastage in homes is absolutely dwarfed by the wastage in other sectors.

Does anyone have any idea at all how insignificant fitting energy efficient (compact fluorescent) lamps are, when the massive Debenhams in Bond Street has it's entire facade covered in what appears to be standard GU bulbs for Christmas? (one of thousands of such stores)

Heated stores always having their door open; Lights on 24 hours even when the stores are closed. And do not get me started on Transport and Industrial sectors.

Theirs looks a little bigger. And they will have it completed in only 8 years. The ISS (which is not ours) was completed in 14 years.

Soon China will become the world leader in technology (if their not already!).

Unfortunately, the US is still caught in historical uses of energy only. We are not as progressive because we are an older country with vast common resources. Any progressive energy used must rely on observing actions of poorer third world countries. The greatest country to study is Brazil.

If you want to rely on solar electricity exclusively, how many solar panels will you need to buy?

Solar energy is one of the most important components of a renewable energy future. Your parents are considering installing photovoltaic cells, which convert the sun's energy directly into electricity, on their roof, and have asked for your help. You do some research and learn that, on a sunny day in Idaho, sunlight at the earth's surface provides about 0.75 kilowatt/m2. Solar panels have an area of 0.5 square meter, operate at 10% efficiency, and cost $63. Your parents use electricity at a rate of 2 kW.

1. If your parents want to rely on solar electricity exclusively, how many solar panels will they need to buy? How big must their roof be (in feet) to hold the array of panels?
2. If electricity costs $0.08 per kilowatt-hour, how long will it take your parents to recoup their initial investment?

Експерт відповідей:

Since there are 24 hours in a day, to be completely off-grid you also need battery back-up, a charge converted, and an inverter.

Buut I digress.

I think the questin is asking how to generate peak power of 2 kw

1 solar panel generate
.5*0.75*0.10 kw
0.0375 kw

for 2 kw
2/0.0375

54 panels

the square footage is 27 m^2

291 square feet.

The cost is 54*63
$3,402

at 2 kw/hr

3402/(2*0.08) hours

21262 hours

Why Germany has it so good while America is going down?

. The European Union, 27 member nations with a half billion people, has become the largest, wealthiest trading bloc in the world, producing nearly a third of the world's economy — nearly as large as the US and China COMBINED. Europe has more Fortune 500 companies than either the US, China or Japan.

European nations spend far less than the United States for universal healthcare rated by the World Health Organization as the best in the world, as US health care is ranked 37th. Europe leads in confronting global climate change with renewable energy technologies, creating hundreds of thousands of new jobs in the process. Europe is twice as energy efficient as the US and their ecological “footprint” (the amount of the earth's capacity that a population consumes) is about half that of the United States for the same standard of living.

Unemployment in the US is widespread and becoming chronic, but when Americans have jobs, we work much longer hours than our peers in Europe. Before the recession, Americans were working 1,804 hours per year versus 1,436 hours for Germans — the equivalent of nine extra 40-hour weeks per year.

People in the countries that are in trouble now economically were the ones willing to go to Iraq — and there is a connection. These are the countries that were much more inclined to go the American route, going into debt heavily, using housing speculation as the engine of the economy, and opening their economies big time to global bank debt and finance.

Goldman Sachs poured tons of money into Greece, and other New York, London and German banks poured money into Spain. None of the bubbles occurred in Germany and in the “old Europe” that Donald Rumsfeld wrote off. Part of Europe is in trouble to the extent — and only to the extent — that it's involved in the American model. Those countries most resistant to the American model are doing fine.

Would you agree that it is the Conservatives and Libertarians that actually care about the environment?

Considering the fact that Conservatives and Libertarians largely support Nuclear energy – a vital importance to solving climate change– unlike liberals who still think renewable energy is the way to go (lol).In the 1980s, we were commissioning 40 new nuclear power plants a decade. If we kept building at approximately that rate, we would have the share of electricity generated by coal and nuclear almost reversed today. Instead of it being 20 percent nuclear and 50 percent coal, it would be 50 percent nuclear and 20 percent coal. Who would argue that from an environmental point of view that wouldn't be a better situation?
I don't care about what that idiot Glenn Beck said.

Експерт відповідей:

The worst polluters in modern times have been socialists: the USSR and China are the best proof of that.

Liberals ban us from using the most environmentally friendly scource of energy known to mankind: nuclear power. They pounce on every nuclear mishap, such as is occuring Japan, to condemn nuclear power regardless of evidence like this:

-For over 40 years after WW2 we tested nuclear weapons — in Nevada! Atom bombs, hydrogen bombs, ground level explosions, under and over ground explosions, high altitude explosions. Other than a few health anomalies for those who lived near the test sites THERE WERE NO CALAMITIES IN THE SURROUNDING STATES RESULTING FROM NUCLEAR FALL-OUT! No mass radiation poisoning, no fingers falling off – nothing!

-The harm resulting from Chernobyl, it turns out, was only in the immediate area, even though the nuclear fallout reached hundreds of miles beyond. Today the “no-go” zone around Chernobyl is 19 miles, leaving Russians with a mere 6,600,000 square miles to live in. Presently the no-go zone around Japan's damaged nuke plants is 13 miles — 13 miles! Oh, my God, how will they survive? It's hopeless!

-Seen any pictures of Hiroshima and Nagasaki lately? Both are thriving metropolises, right on top of their “Ground Zeroes.”

-Casualties resulting from the Three Mile Island leak? Zero. (More people have died in Ted Kennedy's car than all US Nuclear mishaps combined)

Socialists regard us as witless children, spring-loaded to panic, at their self-serving command. They use panic (over manmade global warming, second hand smoke, overpopulation) and now Japan's nuclear power situation, to banish clear thinking. Then they assume their self-righteous role of savior, growing government as fast as they can. Their goal? One world socialist government ruled by rapacious elitist seekers of ultimate power.

Socialism is religion. There can be no reasoning with religious zealots.

Recall when barry said that under his plan, electricity rates would “necessarily skyrocket”? Is LA there?

Households that get their power from the Los Angeles Department of Water and Power could see their electric bills go up between 8.8% and 28.4%, depending on where they live and how much energy they use, under a plan unveiled Monday by Mayor Antonio Villaraigosa.

Appearing with labor and environmental leaders, Villaraigosa said the proposed increases would ensure that the DWP meets his goal of securing 20% of its energy from renewable sources such as wind and solar by Dec. 31. http://www.latimes.com/news/local/la-me-dwp-rates16-2010mar16,0,7870063.story

Lizzie asks…

What would your tax policy be if you were president?

This is mine. Please comment on yours.
-First, a flat tax is the dumbest idea ever and the Bush tax cuts were terrible.
-I am in favor of cutting taxes for everyone. However, 35% should be the minimum government should tax millionaires.
-I feel that the corporate tax rate should be lowered. American businesses need to get competitive with other countries tax codes. Therefore, I'd lower it to 25% and companies involved in renewable energy projects should get a tax rate of 0%.
2nd, I'd lower interest rates , dividends, and capital gains tax on middle income families making $100,000 or less.
3rd, I favor the current capital gains tax. I think America needs to encourage investments. Therefore, I wouldn't change that.
Що ви думаєте? It's a mix of republican values and democrat values.

Експерт відповідей:

I like your list. As far as the corporate tax rate, the reason it's 35% is because loopholes prevent anyone from paying even close to that. So 25% is SUPER low, unless you toss out a bunch of the loopholes. I'd also support a minimum corporate tax rate. Even a 5% minimum would mean some tax revenue from companies that haven't paid in quite a long time.

The capital gains tax is hard. I definitely think we should encourage retirement investments. Especially since, in the last decade, market philandering has left some of us quite short in our savings. Sigh. On the other hand. Mitt Romney makes more money in a day, doing nothing, than most Americans make in an entire year. It seems unfair that he pays so little taxes. So maybe raise capital gains taxes at an elevated income. I'm not suggesting that he pay as much taxes as a working American, but under 15% seems drastically unfair.

Just because something is simple, doesn't make it better. But just thinking about tax code makes me want to burn it all and start over. As president, I would want taxes to be more accessible.

Comparing & Contrasting: Iceland and Finland?

I have been researching and reading a lot about Finland lately and I have made almost a 100% decision that I want to move there for my Master's degree and to pursue an Engineering career (after I'm finished with a few years in the States for my Bachelor's degree). I already know a lot about Finland from the things I have read, such as:
How technologically advanced it is
How the people are very shy and quiet but also are very friendly and cooperative with one another
How little corruption it has
How effective their education system is
Their excellent fluency in the English language
Their scientific and mathematic literacy
Their fairly low poverty rate
Their use of renewable energy and preservation of their environment
Their civil rights, including freedom of press, freedom of speech, freedom of religion, democracy…
Their national pride
etc. etc.

However, I have just recently become interested in Iceland and I have to say I am very impressed with it. Of the things I listed above, how does Iceland compare with Finland? I would also like to know how their job openings in the engineering field compare with Finland (since from what I've heard, there aren'ta lot in Finland at the moment). I'd also be curious to know their relationship with the rest of the world (since I know Finland generally keeps to themselves) and the climate there (yes, I know it's cold as hell, but I've heard that the summer months in Finland are usually fairly nice).

Final note: I know the Icelandic language is extremely difficult to learn, and how most people say it's one of the most difficult in the world. That's why I'm interested in their fluency in English because I want to know how long I can get with English alone (I'm usually not bad with picking up languages through immersion).

Експерт відповідей:

Hey there

All Icelanders speak English more or less fluently. They start studying the language when they're 10 and it's their 1st foreign language of 2-3 (depending on their level of education).
I would expect the Icelandic language to be easier to learn for an English speaker as both languages are Germanic and share a certain vocabulary and grammar while Finnish is Finno-Ugric and has little or nothing in common with the Indo-European languages (French, English, German, Russian, Indian, Icelandic etc.).

I'm not entirely sure I'm qualified to compare Iceland to Finland as I'm much better informed about my own country than the other.Therefore, I think I will describe Iceland in accordance to the list and give you the opportunity to compare them.

How technologically advanced it is
World innovation champions ;)

http://www.businessweek.com/innovate/next/archives/2010/03/once_upon_a_tim.html

How the people are very shy and quiet but also are very friendly and cooperative with one another
Icelanders are generally more outspoken than shy in my opinion, but I have heard both things from tourists; that Icelanders are closed and not very talkative and that they are open and friendly. I guess it's very different between individuals and hard to declare something about a whole nation.

How little corruption it has
The whole financial sector used to be very corrupt (and more corrupt than people generally realized), but it has changed a lot after the crisis.

How effective their education system is
Around or over 30% of working people have a university degree and a lot of emphasis is put on maintaining equal opportunities for everyone, “irrespective of sex, economic status, residential location, religion, possible handicap, and cultural or social background”.

Their excellent fluency in the English language
Considerable excellency, if that's any sort of an answer.

Their scientific and mathematical literacy
Well below Finland actually. According to statistics Iceland ranks similar to Denmark.

Their fairly low poverty rate
Like in other Scandinavian countries poverty is almost non-existent.

Their use of renewable energy and preservation of their environment
Around 81% of primary energy is derived from renewable sources, hydro power and geothermal and the country's goal is to be carbon and oil free by 2050.

Their civil rights, including freedom of press, freedom of speech, freedom of religion, democracy…

Http://www.nationmaster.com/red/country/ic-iceland/dem-democracy&all=1

http://www.nationmaster.com/graph/eco_eco_fre-economy-economic-freedom

http://www.guardian.co.uk/world/2010/feb/12/iceland-haven-freedom-speech-wikileaks

Their national pride
Icelanders are big on national pride (perhaps profusely). A part of the Wikipedia article about the culture of Iceland says: “Yet, an important key to understanding Icelanders and their culture (and which differentiates them from the majority of their contemporary Nordic peoples) is the high importance they place on the traits of independence and self-sufficiency.”
Icelanders are generally very proud of their language, history, nature, culture, music, handball team etc.

To demonstrate that pride I will finish my answer with two videos ;)

Best wishes to you :)

Edit:
I wouldn't say there were no jobs in Iceland. Unemployment rate is approx. The same in Iceland as in Finland (8.5%) – which is actually 4 times what it used to be. And the government is trying to restore the economy by investing in education and innovation.

Why do people say solar panels are too expensive when in CA they lease/install at current electric bill rate?

If your electric bill is $200. you can lease a Solar PV system in CA, and pay $200. for 20 years. No raising of rates !!! No C02 or pollution to offset. The Panels are warranted for 25 years. Yet, so many here buy into the ignorant idea, solar is not viable, it's too far off, why is that? Glen Beck said so? Check rates in your area. 21 states have incentives. If Oil and Defense get corporate welfare solar incentives are fair. The main components are silicon (same as computer chips), metal and glass. It's a no brainer.

Do you think that someday as many homeowners that own cars will own the Solar PV power plant on their roof?

Seems to me that when cars were first invented and people owned horses, and buggies and carriage houses, they denied that cars were reliable and worth the investment. Here in CA you can buy a solar PV system, it's connected to the power company with a bi-directional meter, it's sized so that you get your power from the power company at night and bad weather, and they buy your excess power when your family is at work and school. NO BATTERIES unless you want back-up power from the grid. Most don't have batteries. Then there is CSP, those giant trough-like concentrated solar power plants in the desert. I square mile of CSP could power the country. Sure we'd have to update the grid. The biggest resistance is coming from the Nuclear and Petroleum industries. They want you to think those are better options. Nuclear is a dead end game, we don't need it and it's too dangerous. There is a 30% Federal tax rebate — NOT A SUBSIDY — no more than any other allowable deduction is a subsidy. The power company in many states like CA, NJ, NY and 21 States will also pay a big portion of your initial cost? Чому? They get to buy the excess power from your roof cheaper and locally. It's win/win. If we manufactured here, and people bought the systems like they do cars, the market would drive the industry. Solar, Wind, Hydo, Tidal these are the future of energy and they are renewable . Oil is half gone refered to as “Paek Oil” they will squeeze every dime of profit before it's gone. Would be better to see to it petroleum lasts longer. Corn ethanol is a loser but switch grass ethanol is a winer, made from weeds. Why is corn ethanol pushed instead? The corn industry. It's corporatism driving what is really best into the ground with misinformation and propaganda to head off the emergence of Renewable Energy which is the best way to go. Solar PV on your roof is distributed solar (not a huge power plant) depending on where you live and your local power rates the payback can be 8 years, warranted for 25 years, that's 17 years of free power. The current energy industry is dead set against US buying into that reality, hence all the misinformation. I know a family who has solar and wind turbines. The turbines work great in winter and the solar work great in summer, they sell excess power to the power company and get power when the solar and wind systems are not at their best. Works great and saves them a bundle. That's in CO.

Helen asks…

Should I take a 50% increase on my energy bills for the sake of the planet?

And that's just my bill. No telling what it will do to businesses whose energy bills are more than 10 times mine.

The governor of California is mandating that energy companies provide electricity that is produced by 30% renewable sources such as solar panels and wind turbines.

These companies will raise energy rates so they can collect the money needed to invest in these additional energy sources. By the way, it would cost me $15,000 to solarize my house. Given my current energy bills, it would take more than ten years for my panels to pay themselves.
Roadrunner: You bring up another point. The governor promised 500 thousand “GREEN JOBS”, which were supposed to include solar panel factories.

How much oil do we have left?

Also, when will it all run out if we continue drilling at the rate we are now and which renewable energy source is most likely to rule supreme once petrol and diesel is no longer an option?

Експерт відповідей:

According to peak oil theory we have about half of the available supply left to us. Like some slush drink so far we have sucked out about 1/2 the available liquid. Now increasingly what is left is mixed with the ice and may be harder to remove.

But how long it will last will depend upon our usage. We could switch to alternative modes of transportation and heating for our buildings. This would eliminate 90% of our oil usage. The remaining 10% of our usage would then have about 10 times the supply to draw from and may last ten times as long as our present usage.

Or as we could continue to use oil as the primary fuel for transportation and a significant fuel for heating. If India and China try to pursue an oil economy like the US, each with 4 times our population the supply may last only 1/10th as long as our present rate of usage assuming we could sufficiently increase the flow.

Increasing the flow (adding more wells ie “drill baby drill”) is like putting more straws into our slush drink. It does not increase the ultimate supply, only the flow. The amount of liquid remaining in our drink is constant, but we can be conservative or use it as fast as possible.

The world has been moving to electrical based energy usage for over 100 years and away from fuel based energy usage. Electrical energy storage and wireless energy transfer are the technological hurtles that will soon be resolved and implemented. Electric vehicles are inevitable. Wireless energy transfer could expand their usage even today: http://www.iav.com/us/index.php?we_objectID=15760

Should politics be one big game or should it be for the benefit of the people? What say you?

In its first 40 hours, the new majority of the House of Representatives kept their promise to voters and passed legislation—increasing the minimum wage for the first time in a decade, empowering Medicare to negotiate lower prices on drugs, cutting interest rates on student loans in half, revoking big oil subsidies and using the money to invest in renewable energy —that provided a down payment for a new direction for this country.

These bills are overwhelmingly popular, and are simply common sense reforms. Yet every one of them—and many more—got held up in the US Senate.

Conservatives boast about the “success” of their strategy in discrediting the new majority. As Senate Minority Whip Trent Lott, R-Miss., put it, “the strategy of being obstructionist can work or fail. So far it's working for us.”

How is it working? It's dragging the reputation of the Congress down to the level of the failed president. Conservatives lie in the road of progress and then complain that nothing is moving.

This values partisan posturing over reforms vital to the country. It must be challenged.

It's time to take the gloves off.

The first step is to expose the obstruction to the American people. Let's urge Senate Majority Leader Harry Reid to force a real filibuster. Keep the bills on the floor and force vote after vote, exposing the obstructionists. We'll organize in states across the country to insure that their constituents know exactly who is standing in the way of progress.
Proud Conservatives need to learn how to read, the freaking point is that the Senate has obstructed the bills , what a freaking tard

In 2007, McCain missed all 11 energy -related Senate votes considered key by the League of Conservation Voters, including votes related to automobile fuel economy, offshore Virginia drilling, refinery construction, renewable electricity mandates, energy efficiency, liquefied coal and support for biofuels. The absences prompted the League to give McCain a “zero” rating for the year.
JonChicago – he has received $200 million from oil companies… he is bought and paid for. how does this make him independent or a maverick?

He wouldn't be!! Instead of building solar power towers he wants to build 43 new nuclear plants which cost 3 times the price and put out nuclear waste which nobody wants around them. Also his chief economic adviser is Phil Gramm, who is the former senator that slid the Enron Loophole into the 2000 Energy Bill. To Paulofhouston!! Currently Canada doesn't reprocess it's spent nuclear fuel and it is highly radioactive. Also if it did reprocess, it would be less radioactive but would still have to be disposed of. The cost of Candu nuclear plants are extremely high, even though they are more efficient, they would still produce radioactive waste. Why are you so against solar power tower technology?? Maybe you should check out this website http://www.solarmissiontechnologies.com
before you spout off your McCain ignorance.

Why are there so many social problems in the richest country in the world?

To name but a few, the USA scores lowly in all of the following compared to countries like Japan or Scandinavia (and most of western Europe to a lesser extent):

1) Crime
2) Teenage pregnancy
3) Health/life expectancy
4) Poverty and low income
5) Long working hours culture / less paid hoilday
6) Educational achievement/literacy rates
7) Obesity 8) Environmental pollution eg CO2 per capita, recycling
9) Public transport and renewable energy

Interesting Question!! I think it's because in poorer countries people keep to themselves. For example, in the phillipines where i lived, parents would get mad if a teen had a baby because they can't afford it. Obesity occurs in America because people have enough food and people usually take for granted their health. As for Pollution, In phillipines our pollution was so bad I couldn't find a spot of soil that did not have a plastic bag buried or on top of it!

Is China taking a more sensible approach to coal-fired energy?

I have read that since about 2006, China has been 'retiring' many of its smaller, older, less efficient coal-fired plants. To offset the closure of these plants, they are building new, more efficient coal-plants that don't put out as much in the way of pollutants.

As China is rich in coal resources, don't you think that it is wise for them to make the most out of their cheap, readily available energy resource?

China closing down small coal-fired plants
Yvonne Chan in Hong Kong, BusinessGreen, 31 Jul 2009

“Facilities with a total generating capacity of 54GW have been shut from 2006 to June this year, Sun Qin, deputy director of the National Energy Administration, said yesterday.
The announcement follows the release of a Greenpeace report earlier this week that called for China to phase out outdated facilities with a generating capacity of less than 100MW and set a renewable energy target of 30 per cent by 2020.
Sun said the number of plants with a capacity below 100MW comprised 14 per cent of the total proportion of energy -generating units, down from 30 per cent in early 2006.
However, in the meantime new coal-burning plants are still being built at a rate of 70GW per year, although Sun said most of the new facilities have significantly higher levels of energy efficiency than those they replace.
China is the world's largest coal producer and consumer. The fossil fuel accounts for at least 70 per cent of its energy needs – a factor that has led to its top ranking in global greenhouse gas emissions.”

We have 2 and half times as much coal as China, yet we don't utilize ours. China is utilizing their resources as are every other country in the world so yes they are taking a more sensible approach IMO.

Can you answer five short poll questions?

1. Should the government tax income earners making more than $250,000 annually at a higher rate or the same rate as income earners making less?

2. Should government provide tax incentives for businesses and individuals who use wind, solar or other renewable energy sources instead of nuclear, oil, coal or other fossil fuels?

3. Should the US government support Israel's occupation of the West Bank and Gaza Strip or should the US government support an independent Palestinian state in those territories?

4. Should the government legalize same sex marriages, civil unions, or neither?

5. Should the government keep abortion legal or criminalize it?

Експерт відповідей:

1. Only tax GOVERNMENT Employees higher that make over $250,000 annually. Flat tax on all the rest.

2. No Renewable Energy is unlikely to be directly econoically viable. The energy required to create the renewable energy infrastructure cost too much energy.

3. Так! If you give Palestine an independent state either they have to stop the terrorist or be attacked by the Isreal. Do the rulers of Palestine wish to put targets on their house?

4. Ні! Why should the single taxpayer subsidize others?

5. Over turning Roe V Wade gives the option to the states.

How does my English essay sound?

The topic is “The greatest evil facing our world today”
It is actually a speech to be given in front of a massive crowd

The greatest evil facing the world today is the footprint left on this planet by mankind. The earth is the only one of its kind that we have. Our planet is being worn out by the unnecessary actions that we take each second, minute, hour, day and year. The ridiculous amounts of greenhouse gases that we emit into our once clean atmosphere are going to result in the earth punishing us at anytime she wants. Our survival could be lost in as little as twenty-five years if our behavior towards the environment doesn't change for the better.
The depletion of the ozone layer will be complete within 200 years at the rate it is being depleted now. If this occurs, no life will be able to live on the surface of the earth. There are already some holes in the ozone layer which have caused immense skin cancers and blindness in animals. Frogs all over the world are becoming dreadfully deformed. In addition, over fifty-one acres of rainforest are destroyed by the developed world per minute.
Currently, twenty-five percent of western pharmaceuticals derive from rainforest ingredients although less than one percent of all rainforest materials have been scientifically tested. This shows that the rainforest could have the cure to the vast majority of the diseases that cause troubles in this world. It could have probably been easily ALL the diseases if the extinction rate of all species was not as high as it is now. Currently, over 130 species are lost per day and more than 99.999% of all species that once lived on this earth are now extinct. Nearly half of the world's existing species will be eliminated in the next twenty-five years due to rainforest deforestation.
The amazing thing is that we still consume non- renewable energy much more than we use renewable energy . We consume almost 1.4 million barrels of oil every forty minutes whilst the solar energy that hits the earth's surface in forty minutes is enough energy for the whole world for a whole year. But this does not make us think about the vast amount of energy that has less effect on their world. If we did, the earth would be a much healthier and cleaner place to be in.
Politicians are actually accepting the reality of our situation and are taking actions. They have been given the irritating wake-up call of land loss due to the rising sea levels. Some people are thankful that they are starting to realize our problem. I for one am not. It shouldn't be economic problems that influence their actions, but moral beliefs.
