Abstract
A rotary turbine including a source of a pressurized medium and a rotor assembly. In one embodiment, the rotor assembly includes first and second rotors, and the surface of each rotor is substantially smooth. The pressurized medium flows between the rotors, turning the rotors. The smooth rotor surfaces do not cause substantial turbulence in the medium. Accordingly, the exit velocity of the pressurized medium is maintained at a substantial higher level than if the rotors included blades or other protrusions extending outwardly.
