Air Powered Car
This video show two types of air motor designs. Funny thing is that this video was posted in 2006. I guess when you get 11 cents per gallon effective then the big oil interests just don't allow anything to ever come of that technology. Yet again it comes down to us doing for ourselves. The DIY movement is getting stronger because, frankly, it has to. Governments and big business just aren't going to do it for us. And, in all likelihood, will actually stand in your way and try to stop you. If you want to experiment with an air engine, then I suggest doing what I talked about the other day. Take an old lawn mower engine, like a 3.5 hp 4 stroke and modify the cam shaft so it becomes a fairly efficient air motor. (see the second video here) Then you could get a used scuba tank and make all kinds of things. Like air powered bike, trike, lawn mower, backup generator, backup water pump, etc.

air powered bike update
This is a video of someone actually running an air powered trike.
But this video below shows more promise.
In this video he is sort of on the right track. Forget the selenoid at the top where the spark plug goes. They are only good for so many cycles and will wear out pretty quickly. Besides, the 4 stroke engine already has great valves in it. And he makes the intake and exhaust work together for air power by adding the lobes on the cam shaft. I can't see it getting more efficient than that. You just need a cheap air compressor and a scuba tank or better, a carbon fiber tank. I like the idea of using compressed air instead of batteries. And imagine doing conversions on cars. You take the camshafts out, add the lobes and grind them smooth. Take the gas tank out and replace with a 10,000 psi carbon fiber tank. Have a double reducer on that that goes down to 100 to 150 psi. You could fill up at a welding shop or at home if you have a high pressure compressor. And once you pressurize a tank, it doesn't lose its power like batteries do even just sitting there. Gas stations could start adding high pressure tanks and compressors so they could fill up the new vehicles.
