Hydrogen Peroxide

zod

This video shows a gas cutting equipment running off water and also a car that gets 100 miles from 4 fl oz of water ..:eek:

I assume the electricity required for the electrolysis would be formidible tho?

Hydrogen Peroxide is not water.
It is rocket fuel.
And not only that it can be used as a monopropellent too.

Any impurities and it decomposes. Things like metals, rust, blood etc will catalyse this. In short HTP is not viable for consumers.

It's an oxidant so to use it you generaly need a fuel, a greener substance would be air which is freely available and has no transport costs.

H2O2 is handy for when you can't use air as in subs and rockets. The Kursk was lost due it. The Brits used it in aircraft rockets, subs and rockets, but they don't use it any more because it's very nasty stuff.

iirc you use sodium to make it so very energy intensive

Hydrogen peroxide was the fuel used in the torpedoes on Kursk http://en.wikipedia.org/wiki/Russian_submarine_Kursk

It is very unstable when exposed to atmosphere
