I'm sure you didn't mean to do this, but please, let's not add further confusion to this thread.
The sun doesn't "burn" hydrogen. It fuses hydrogen nucleii to form helium nucleii. Using hydrogen as a fuel in an oxidation reaction burns orders of magnitude cooler. .)
Okay, so have we officially transformed this thread into a "cold fusion" energy thread?
Personally, I'd rather discuss the air speed velocity of an un-ladened swallow.
