is there really a car that runs on water?

There is a saying: "Like many things in life we laugh because it's funny and we laugh because it is true." It seems it uses the principle of electrolysis i.e. direct current applied to water builds oxygen on one electrode and hydrogen on the other. The hydrogen from water is highly combustible. (I recall the Hindenburg burning violently (it floated using massive amount of hydrogen!)) It seems the catch is that igniting hydrogen in a piston results in water -that drains the lubrication ... I wonder how they fixed that. I hope above made some sense :) Cheers :)

Yes there is! As we all know, hydrogen is an excellent fuel and water has two parts hydrogen and one part oxygen. What the car does is that it breaks up the molecule to extract hydrogen. This is then used to power the car! When hydrogen burns up in the engine, it is converted back to water! No pollution nothing! neat huh?
