Peak Oil

You a bit off with the first one Perndog.

Hydrogen can directly replace Gasoline.

Hydrogen is an explosive (Note the Hindenburg)
But it is also a gas (vapor). A redesign, and complete sealing of a car and engine would be required.

It is more explosive, and packs more punch then Gasoline.
(which is why Car Companies are looking at Hydrogen Fuel Cells and not pure Hydrogen motors)

Any engine forced to put up with the rigors of a Hydrogen fuel source would shake itself apart if not close to perfectly made.

And my above statement is partially correct. You need alot more energy then from a simple battery. Hydroelectric Dams have everything set up to produce Hydrogen, just not compress and hold it.
