Apparently in the future (could be 2012) F1 cars are to be diesel powered :^) Before WW1 a car was invented which ran on water, well probally a steam car that had performance far greater than any thing mad to that date, it was ment to be in performance terms simular to a DB7 Aston Martin, but it had it's pattent bought by a oil company and they just put a lid on it so they could sell their oil/petrol.
