First of all, there's no such thing as a "water powered car". Either it runs on straight hydrogen, or it runs on a 2:1 mixture of hydrogen and oxygen. Whether or not your talking about a hydrogen engine or a fuel cell car, people don't seem to realize that you don't just drill a hole and pump out hydrogen. Hydrogen comes from water through electrolysis, requiring electricity. Basically hydrogen is only an energy carrier, much like batteries. In fact, batteries are nearly twice as efficient from power grid to motor, and therefore use less coal/nuclear generated electricity. If you're thinking about the cars that you fill with water with no other energy source, I'm sorry, but such a car would violate at least two of the laws of thermodynamics. If you want all the science behind that, read the wikipedia source. The only (non-validated) car I've seen anywhere that might actually be a "water car" probably also uses some metal hydride in the process.
