Claim 29:
30. A system for use of one of compressed air and combustible fuel, the system comprising: an internal combustion rotary engine which comprises a non-rotating outer housing, a pair of counterrotating rotors within the non-rotating outer housing, and a power shaft, having an axis, to which each of the rotors is coupled, one rotor coupled directly and the other rotor coupled through a reversing gear arrangement; in which each rotor has a structured inner surface perpendicular to the power shaft axis, and each inner surface counterrotates past the other; in which the engine mixes and ignites the compressed air and the fuel within chambers formed by structured inner surfaces of the rotors, causing the rotors to move and the power shaft to rotate about the axis.
