Nope, wasn't joking, but it was a random thought i had today, just thinkin about alternative engines and how else you could get power from a fossil fuel free engine. Thanks for the input, yea i dunno how much power could be produced, or how to maximize air pressure going to the cylinders to create as much pressure in there as the gas does. Gonna give this more thought, ask around... ill keep ya posted. Just hope no one steals the idea if it turns out to be a winner!

Keep your eye on hydrogen fuel technology. I predict in 20 years gasoline will have been replaced by hydrogen fuel cells.
