Nobody likes what we see when we arrive to the gas station, but we stick with the fossil fuel anyway. I think everyone's heard of someone claiming that some guy made a car that ran on water. Sounds too good to be true, which is right because it's impossible. While water is made of hydrogen, the bond with oxygen basically got rid of its useful energy. Unless someone could make a very efficient mini-hydroelectric plant, I really doubt it. It would probably break some law of thermodynamics as well.
