_NOW_ I get what you're trying to describe! I must say, the Telephone Game this thread has produced is amusing. Oddly enough, I was thinking of something similar recently: use a small wheel-driven piston to compress air on demand into a small container for use on a pneumatic-horn. In fact, I imagined that the "on-demand" could be simply using the brakes: engage the pump only when braking thus assisting braking. In any case, I'm afraid what you're proposing is extremely inefficient. I suspect there are available solutions to a simpler wheel-driven compressor-pump, and I'm interested to know what these solutions are.
