Bob:

Good points. Something else to think about - the hydrogen atom is the smallest of all the elements - it tends to leak through everything, particularly when under pressure. The latest idea for keeping your tires from slowly going flat (air molecules do leak through rubber tires) is to use nitrogen. It's a larger molecule than oxygen, and doesn't leak out as fast as air which is about 80 percent oxygen. Propane doesn't seem to leak out of tanks or through valves because is a a long chain (large) molecule consisting of carbon and hydrogen.

There is a rumour here in BC that Ballard (the fuel cell company in Vancouver, BC) has given up on fuel cells for anything but stationary usage - they realized a while ago that hydrogen fuel cell cars weren't practical.


The definition of a corporation that I think is most accurate; "a pile of money with no conscience".
