what we really need to do is work out how separate water in to hydrogen and oxygen (cold fusion) so cheap that its basically free power stations would produce nothing but water from burning the hydrogen in air which would then be used to power the turbines

same would work in cars. distilled water could be stored in the fuel tank it would then be separated into the H and O, burnt then waste which would be water be put back through the system to the tank. granted some will be lost through the process

then again in a filling station water just as expensive as petrol least you wouldnt need very much
