i hear all this cool hydrogen stuff but i am looking for boilers and furnaces that run on water. i found a company that makes one but it is in canada. does anyone know where i can find even a boiler that does this?
Energy can neither be created nor destroyed; only changed from one form into another. If you have an electrolytic process to convert water into hydrogen and oxygen, that takes energy. You will always lose a little more by heat in that process that you will not recoup by burning the hydrogen back into oxygen again. A far more efficient way of getting heat from your 12V DC source would be to just stick a heating coil on it. So I'm afraid this is just a pipe dream, like so many promises of perpetual motion, cold fusion and simple cures for cancer. You cannot get more energy out than you put in, any more than taking money out of the bank and then putting it back in makes you end up with more money. The bank always wins, and in this case the laws of thermodynamics will always win.
