Apparently not. All kinetic energy goes into compressing air and storing it.
Higher efficient air engines are about. The Australian rotary unit is an
example. The French piston unit uses air and petro in the same cylinder. I
think even the Canadian Quasiturbine can incorporate air and petro in the
same rotary unit.
