[TheForge] Hydrogen storage (was: Hellooooooo!)

[Ralph Sproul]

	James, I wanted to thank you for this info on hydrogen with the volume it
takes to equal 1 gallon of gas............this sure puts things into
perspective on how it isn't coming on line quickly as an automotive fuel.
	Seems making it at a rate needed would be better than trying to store it
and when I see a fuel cell demonstrated at a show and how fast it generates
the fuel - it's obvious there's room for improvment and we aren't driving
out cars fueled on water yet.

	Even if we opted to consider BTU's instead of weight from below - your
still talking .02 cu ft for gas and 63 cu ft. for hydrogen for equal amounts
of heat output.

Hydrogen is much more efficient than gasoline pound for pound, it is
just that a pound of hydrogen has a volume of about 190 cu ft at
atmospheric pressure!

1 lb. Hydrogen 61,000 BTU's, 190 cu ft at 1 atmosphere
1 lb. gasoline 20,500 BTU's, 0.02 cu ft at 1 atmosphere
