    Hydrogen produced from water using aluminium and gallium

    http://www.abc.net.au/rn/scienceshow...htm#transcript

    Here's Peter Pockley with the swashbuckling Professor Jerry Woodall at Perdue University in Indiana USA.

    Jerry Woodall:
    We have learned how to split water with a material that normally won't do it because of a passivating oxide that covers it, that material is aluminium, and I figured out a way of disrupting this passivating A oxide so that the water that comes in contact will react with the aluminium forming hydrogen, aluminium oxide and heat. The hydrogen part is a highly volatile gas that is hard to store, transport and use safely. No one has yet figured out how to provide hydrogen to tens of millions of motorists without great risk. What I hope to show you today is I have found a way to get around those risks for hydrogen, and the bottom line is I can make hydrogen when you want it, or hydrogen on demand.

    Okay, so what we're going to use is aluminium now. Aluminium is not thought of as a fuel but if you were a thermochemist and you were asking the question of the energy content of aluminium...suppose I compare it to oil. So I take some aluminium and take it to its oxide, namely aluminium oxide, compare that energy that's released to oil, and it turns out that a pound of oil will give you 19,000 BTUs, British Thermal Units. Well, aluminium will give you 14,000 BTUs per pound. So aluminium, even though you don't think of it this way, is a very high energy density material, and the amount of energy released when it goes from aluminium to aluminium oxide is a lot, just like when you burn oil, that's a lot too.

    This has been done before and the inventor died young under mysterious circumstances.
