content: Except that the article states"You may ask, 'Wouldn't that mean it breaks the first law of thermodynamics?' The answer, happily, is no."

content: it is possible to break thermo law, by putting aside the external sources, counting only the internal output.

content: So to summarise, your contribution is factually incorrect in three respects1, grammatically inaccurate2, late and redundant3. Pretty impressive for a post with no content except the link.1 There are four laws of thermodynamics, not one, it doesn't violate the first, and even if it did 230% efficiency would mean a 130% violation.2 It'sanLED.3 Psi reported this discovery (accurately) back in March.Yes, I'm really Bored@Work.

content: Good thing that it doesn't violate the laws of thermodynamics then. But what the hell, who needs accuracy when you can have a nice headline instead.

content: Everyone knows you can do this by connecting a motor to a generator and then wiring the generator back to the motor through an amplifier. That way there is enough power for the motor and some left over for the LED. There are lots of videos on YouTube that show how easy this is

content: Quote from: ciccio on November 12, 2012, 06:16:54 pmIt depends on how you sound "LED" in your mind when you read it.If you sound out the letters individually it would be "an ell-ee-dee", however if you sound it as if it were a word, it would be "a led".In English-speaking countries most people sound out the letters and so it would be most natural to write and say "an LED".

content: Abbreviations that start with the consonants F, H, L, M, N, R, S and X attract an, because they start with vowel sounds.i wasted 2 minuets finding that outi studied electrical engineering and computer science not English language, besides when did this become a grammar nazi forum ?

content: no, he's rightAbbreviations that start with the consonants F, H, L, M, N, R, S and X attract an, because they start with vowel sounds.Abbreviations that start with the vowel U attract a, because U starts with the consonant sound 'y'.

content: Quote from: ciccio on November 12, 2012, 11:25:36 pmAlthough, the word Nazi often causes offence even if none was intended, especially in some European cultures. Nowadays, the word Nazi often used as a slang word for someone who tries to force their values onto everyone else.

content: Quote from: vk6zgo on November 13, 2012, 03:09:43 pmI've heard people say both. Pronunciations of many words vary, for example some people pronounce the letter I in either and others sound the letter E, either way is valid.
