Actually, it's "sourcastic".

That whole website is a "Fox News" for Lefties.

You can't get something for nothing. It takes ENERGY to break up and separate the hydrogen and oxygen in water. You can try it yourself, put a wire from the positive pole of a battery into water, and a wire from the negative pole into the water, and the current flowing between the two breaks down the water into hydrogen and oxygen bubbles that collect around the wires and bubble out. When the battery runs down you can stick a match near the experiment and the hydrogen and oxygen will combine (explosively) to form water again, plus a lot of light , noise and unpleasantness.

It takes exactly the same amount of energy to split up the water as you get back from the water when it burns. There is none left over to run your car with. To put it bluntly, that article is a lie.
