If you are getting your air from a compressor that is supplied by a fossil fired boiler, then the efficiency is really terrible. If your air comes from a wind driven compressor, or the compressor receives electricity from a solar powered system, then you are really doing something.
If not, you, and the world would be better off driving a light weight, high efficiency internal combustion engine powered car.
