If you have lots of hydrogen lying around, its a great fuel. Burn hydrogen and get water vapor!!! Problem is, hydrogen is reactive/explosive in air and is not found in its atomic state. It combines with oxygen to form water. A most abundant substance on earth. According to Wikipedia hydrogen makes up 0.000055% of the atmosphere so there is not much to get that way. NASA fills rocket tanks with liquid hydrogen so we can make it easy enough. But it take a lot of energy. That's the rub. If it were competitive with gasoline it would be here. Greenies are pushing it, but haven't thought everything through as usual.
