Air Power will replace Gasoline?

well i just read something intresting.....remember when we used to build ballon power mini toy car? someone plan to use the same concept on a real car.....Air Car
How the Air Car Worksif its works, those oil company cant milk people for money anymore XD
well atleast not as much....

It sounds plausible, but if we were to use a self regenerating power source propelled by Air, we should need electricity to refill the tank. (Air pressure has to be consistent)

we all saw what happend to the elertric car didnt we i would think this would go just as far
