Abstract
Abstract A power generating system which includes a turbine and a radiant heat boiler for supplying motive fluid to the turbine. The turbine is provided with a stator having a cylindrical bore and a cylindrical rotor provided with a substantially uniformly rough lateral surface. The inner wall of the turbine stator is provided with a continuous oblique helical groove which serves as a passageway for the motive fluid. The lateral surface of the rotor has a relatively high drag coefficient and the rotor is actuated to a high rotational speed by the motive fluid flowing in the stator passageway and past the rotor lateral surface. The radiant heat boiler comprises a hermetically sealed enclosure having a substantially globular inner surface covered with radiant heat reflecting surfaces, a substantially globular pressure vessel centrally situated within the enclosure and spaced apart from the reflecting surfaces about its entire periphery, a radiant heat source mounted within the space between the reflecting surfaces and the pressure vessel.

Claim 1
Independent Claim
127 words
A turbine comprising a stator having a cylindrical bore; a cylindrical rotor coaxially journalled in said stator and provided with a substantially uniformly rough lateral surface; and an output shaft secured to the rotor and projecting axially from one end of the rotor; said stator being provided with a motive fluid inlet port near one end of the rotor and with a motive fluid outlet port near the other end of the rotor; and the inner wall of said stator being provided with a continuous oblique helical groove over that portion of the inner wall which is coextensive with the lateral surface of the rotor, one end of said groove communicating with said inlet port and the other end of said groove communicating with said outlet port.
Claim 2
Dependent Claim
