ABSTRACT:
An energy conversion device which benefits from forces associated with angular momentum. A mass such as fluid is directed through a conduit from one elevation to a lower elevation with the conduit configured to conform to a decreasing cross-sectional area and oriented in a spiral of substantially conical shape so that fluid entering into the conduit accelerates both by virtue of the decreasing cross-sectional area of the conduit and by the velocity added to the fluid by successively constricting the fluid to an ever tighter spiral path of lesser radius ultimately to an output of the conduit which is in communication with a converter such as a turbine. The converter has an interior passageway in axial alignment with an outlet of the conduit and includes an interior vane which coacts against the fluid exiting from the outlet of the conduit imparting rotation to the rotor which circumscribes the passageway. The rotor is supported on a bearing block and operatively couples to a stator for power output.
