Water can really power a car, this is for real. However there is a small caveat: 100% water cars will take probably tens of years to be produced on a large scale. The current available method is still using gasoline or diesel fuel.
Water is a supplement to gasoline or diesel fuel that increases mileage tremendously.
Simplewaterfuel will show you how to use a little electricity our of your car battery, to separate water into a gas called "HHO", 2 parts hyrogen and 1 part oxygen.
