I am not sure whether to post this as a question of electronics or automotives, Please bear with me as I am a new member.

Here is my question. Recently I have heard that it is possible to convert your vehicle car or pickup so that it will run on other types of fuel, other than petroleum based products.

Namely there has been considerable talk about using water, yes plain old H2O to increase gas mileage and improve the power and performance of the vehicle at the same time. With gas prices going from $3.00 dollars per gallon and more it would sure help if I could get every extra mile per ounce out of the fuel.

Has anyone out there done it? If so what were your results? How much did it cost to retrofit your vehicle? I have heard it is possible to separate the hydrogen and oxygen through a type of electrolysis and inject the hydrogen in metered amounts into the combustion chamber. Thus increased power performance and gas mileage. And no pollution either.

You can't run a car on water.

The laws of thermodynamics clearly show that the amount of energy needed to separate hydrogen and oxygen is more than the amount of energy a hydrogen engine would produce.

It's a nice idea on paper but it won't work.
