Abstract: A process and system of extracting useful work or electricity from a thermal source, wherein heat energy from the thermal source is used in the form of a heated collection fluid; a first side of a heat exchanger is filled with a liquid or supercritical working fluid; fluid flow out of the first side of the heat exchanger is closed such that a fixed volume of the working fluid is maintained in the first side; the heated collection fluid flowed through a second side of the heat exchanger that is adjacent to the first side to affect a transfer of heat from the heated collection fluid to the fixed volume of the working fluid to raise its temperature and pressure; the pressurized working fluid is released from the first side of the heat exchanger upon the working fluid reaching a threshold state; a flow of the pressurized working fluid is directed to an expander capable of converting the kinetic energy of the pressurized working fluid into useful work or electricity; and the foregoing steps are repeated. A plurality of such operably coupled heat exchangers may be used in a manner such that the timing of the pressurized working fluid from each heat exchanger to the expander is offset.

Abstract: A boundary layer turbine comprising a housing having an inlet and an outlet, the inlet receives a flow of pressurized fluid; a shaft extending longitudinally through the housing and journaled for rotation about its longitudinal axis relative to the housing; a plurality of nested cylindrical tubes of progressively wider diameter arranged coaxially about the shaft and connected to the shaft, wherein adjacent tubes define a cylindrical fluid passageway there-between that is in fluid communication with the inlet and the outlet, thereby the plurality of tubes define a plurality of passageways; at least one nozzle coupled to the inlet configured to direct the flow of fluid from the inlet into the plurality of passageways and against the plurality of tubes at an angle to a normal plane to the curvature of the plurality of tubes and at an angle to the longitudinal axis of the shaft, wherein the angled flow of fluid imparts rotation to the plurality of tubes and the shaft and flows towards the outlet where the fluid is discharged, and wherein the rotating shaft may be used to provide kinetic energy.
