gravity MAYBE??? he may have an electric motor to reverse... and a turbine has a generator anyways if its well hooked up like an airplane... so it produce power even if its not pumping air.... just eats fuel like mad.

Seems like the dumbest idea ive seen since the jet powered lawntractor/golf cart.

That car is worth 20$ before and maybe 5000$ after LOL...
