I'm thinking it will be easiest to apply this idea to a slightly enlarged go-kart type frame.

You start out, with an electric conversion kit such as can be purchased from many places on the web (I'll find a link for ya if needed)

These come in many shapes and sizes, with motor, powersupplys and batterys in some cases. Install this as you normally would.

Next step is to rig up a tank of compressed air, possibly even a refrigerated tank to increase the capacity. This, would inturn, be used to turn a suitable sized Air Motor, which is essentially a shaft proppelled by compressed air. The air motor would be coupled to a generator, used to recharge the batterys.

Thats the basic Idea, I'm aware there are more electrical components I would need to consider, but I think this Idea has some potential.

But it also seems it takes a lot of air to produce horsepower, and my tank would need to carry a good amount of pressure, perhaps in the order of 3000 psi or better.

The other problem comes in filling the tank. A future solution for this problem could be to add yet another component to the system, consisting of a small Hydrogen powered engine to turn a compressor, in turn filling the Air tank.

See, I'm getting better, no perptual motion at all. Close, but nothing is free, just hopefully really cheap over time.

I'm also curious if one would be better off trying to use compressed air as your motive force, instead of using it to generate electricity to supply batterys. Any thoughts? Should I quit wasting my time and let the governments handle it?

Actually, its more wasteful than you think. When you compress the air it will heat.(Charles' Law). This heat will come from the work of compression, and will bleed off as the tank cools back to ambient temp. If you then further refrigerate the tank, you will draw off more energy (as heat) This will drop the pressure in the tank (Charles' law again), and reduce the amount of work you can get of it even further.

Further more, if you compress air, cool it, and then let it re-expand you are likely to produce liquid air. (see my post "making liquid air (old stlye) .
