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: Assuming this truly can be done:
    It's cheaper for us and better for the environment = AMAZING
    It's bad for oil industries, capitalism because the supply of water is so high, and bad for most economies = NEVER WILL HAPPEN IF GOVERNMENTS CAN AVOID IT

    this is indeed very sad but the truth, although you should take into account not all countries have a good water supply and that we have messed up our oceans far more than enough.
    • Mar 3 2011: "Assuming this truly can be done..." It can't! You can prove anything if you start with a false assumption.

      Water is nothing more than hydrogen combined with oxygen. The two elements are held together by a chemical bond. It doesn't matter how you separate the two elements from each other, whether by electrolysis, photosynthesis, or any other means, the energy required to break the bond is greater than the energy generated when they combine again, which happens when you burn hydrogen in oxygen. It has nothing whatever to do with the big bad oil companies, capitalism, or anything else except basic Grade 6 physics and chemistry.

      Anyway, burning hydrogen in vehicles would be a non-starter as it has a tendency to explode. Experimental cars that do run on hydrogen use fuel cell technology, which is a whole nother issue. But you still can't get something for nothing.
    • Mar 3 2011: We do not expect every country to follow suit in order for US to start making economical decisions.
      Whether or not a country has a "good water supply": I will presume there are 'people' in the countries you're referring to, and seeing as people NEED water, I'm guessing there is some kind of supply.
      And, when comparing the availability of water to that of oil in my own geographic region: I know where a river is nearby, but not an oil well... so does this help me determine that I don't have a "good oil supply"? Or can that shit be pumped through veins across the Earth for thousands of miles, just like water?

      Mar 3 2011: I agree with you Ambar, there are many issues that go with this problem.
