Abstract: A Stirling cycle engine of unique mechanical arrangement which operates on a principle similar to that of a planetary gear, the orbital members being the displacer shaft, piston crankshafts and engine body. The pistons reciprocate when thermal energy flows through the engine, causing the displacer shaft to rotate. If the displacer shaft is retarded or held stationary by an applied electric field, the engine body begins to revolve, transmitting power to a load. The engine body is sealed, with no dynamic seals or shafts exiting the engine body, and the design is such that size can be increased without pressure containment considerations making the engine impractical. Engine mass is used as inertial storage to increase efficiency with fluctuating loads, internal engine speed is constant for high fuel efficiency while dynamic power to the load is infinitely variable and the engine is specifically designed for ease and economy of production.

Abstract: An apparatus for producing electrical energy from multidirectional water wave action including a central support for placement on the bottom of a body of water with the support extending vertically above the surface of the water. A multiplicity of shafts extend radially and horizontally from the central support. A multiplicity of floats are supplied for each shaft with an elongated member connected at the upper end to each float and in engagement with a weight connected to the lower end of each elongated member and extending below the shaft. A one way clutch is mounted on each of said shafts and associated with each of said elongated members intermediate the ends thereof adapted to rotate each shaft in one direction when the float raises on a wave and not affect the shafts when said floats lower in a trough between waves. Each of said shafts is connected to electrical generating means for actuation of the same.
