Why we still don't use water to run our engines?

Scientists had already discovered that hydrogen can be extracted from water to power a car (the media said so). But due to technological and political reasons that could seriously disrupt the oil industry.

Water is one of the most powerful and affordable sources of energy for sure. But why we still don't use it instead of oil, daily?

    Mar 3 2011: water is not a source of energy. Hydrogen is.
    There is no abundant hydrogen available on our planet, the only way to get sufficient amount of hydrogen would be to use electricity to break the H2O molecule to get hydrogen. From extracted hydrogen, as a result, you will receive less energy in return as to the amount that you spent in creating hydrogen. In sum, you end up loosing more energy (using electricity), than getting in return.

        Mar 3 2011: how scalable would that be?

          Mar 3 2011: Research is still being done but from the current prototypes it seems fairly scalable a large surface area covered with pigment is necessary as well as a method to collect gas.
