there is more oil under alaska than the whole of the middle east put together, they know it, they know we know it, but they wont tell us about it, but more to the point, we dont need it, we dont need to be burning oil to power cars any more, every time someone invents a better way, the inventor ends up dead and the oil companies buy the idea then lock it away in a safe and forget about it, you can use vegetable oil to run diesel cars, bio diesel is even sold in Germany at the fuel pumps, sales of it slumped when they slapped the tax on it and caused it to becoem more expensiv that the normal diesel being sold by the big oil companies!
