 The amount of heat created could also be used to generate energy that can, in turn, provide several different tasks (turbocharge the compressor, precool air entering the compressor, etc). I have no data regarding temperatures generated bu the compressor, but it's a two-stage compressor. While it is crucial to maintain as low temperature as possible of the air that enters the second piston, beyond that, we have place for experimentation.
-I have a crazy idea regarding hi-volume sanding using this setup. Obviously, with large volumes of air running out of the sander's nozzle, we will be running out of air really quickly. The alternative here is to use small amounts of heavily compressed air to burn efficiently (we're aiming for a deflagration) an air/propane mixture (wood gas anyone?), and using the generated pressure as a motive fluid to power an injector. Heat generated will allow for production of steam, that can be delivered to the motive fluid prior to its entrance into the injector. Such a device should also be an effective vacuum pump for gasses and liquids (a blessing if your basement ever gets flooded). I've got no calculations on this one, though, as such calculations exceed my current abilities :)

The alternative here is to burn small amounts of heavily compressed (efficiency!) air/propane mixture (could also be oil or wood gas) in a chamber, and to use the generated pressure as a motive fluid to power an injector. Heat generated will allow for production of steam, that can be delivered to the motive fluid prior to its entrance into the injector, but after the fuel has burned. Such a device should also be an effective vacuum pump for gasses and liquids (a blessing if your basement ever gets flooded, ask me how I know). I've got no calculations on this one, though, as such calculations exceed my current abilities. I did however convert a Karcher pressure washer into a pretty efficient injector for expelling water out of a basement. It involved a PVC pipe, and could spew water out at rather impressive volumes, even though the injector nozzle was misaligned.
