    There are none, because the whole concept is not possible.

    Answers that say otherwise, like the other one you have here, are from shills that collect a percentage from the scam outfits.

    Apparently lots of people get taken by the ads and buy one and install it, but any improvement in MPG is due to more careful driving habits — they want it to work, so they drive more conservatively and — viola — they get a MPG improvement.

    But ask any competent engineer, or mechanic and they will tell you the whole idea is laughable.

    I think it’s interesting that there is still a ton of hype about water powered cars. 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.
