  1. Check out the "liquid Piston" engine. It swaps the rotor and stator shapes giving three chambers (three expansion points per revolution) and a long blowdown period (high efficiency). It would work on compressed air just as the Wankel does.

  2. Use an aluminium compressed air tank to power the motor.
