A portion of the internal energy of a mass flow of a compressible fluid, such as air, is transformed efficiently into greatly increased flow kinetic energy by passing the flow through a set of converging nozzles in a cylindrical rotor; this accelerates the isentropic flow to sonic speed generating large thrust. The nozzle thrust generates torque, thus rotating the rotor which is coupled to a power take-off for doing useful work. The mass flow of air through the apparatus is supplied by a vacuum pump.

1. A method of efficiently generating and extracting power from a flow of a compressible fluid for doing useful work, comprising: a) inducing and sustaining a chosen mass flow of said compressible fluid by a vacuum source,(b) conducting said chosen mass flow of said compressible fluid from said vacuum source into and through a set of two or more conical nozzles formed within a rotor, said rotor being cylindrical and mounted on a central shaft, or axle, each said nozzle in said rotor having an equal minimum or throat cross-sectional area, and where, moreover, said throat cross-sectional area in each said nozzle is also that area which will pass an equal portion of said chosen mass flow of said compressible fluid at sonic speed,(c) arranging said set of conical nozzles circumferentially and symmetrically in said rotor, said set of conical nozzles being situated in a same plane of rotation, said plane of rotation of said set of conical nozzles being at right angles to an axis of rotation of said rotor, each said conical nozzle having a respective larger flow entrance port situated on an outside rim of said rotor, each said conical nozzle leading through said rotor so that a respective smaller end flow exit port opens into a central, cylindrical inner fluid flow chamber of designed radius inside said rotor, each said conical nozzle being aligned in said same plane of rotation so that said exit port of said conical nozzle is tangent to said rim of said inner fluid flow chamber at said designed radius,(d) each said conical nozzle having a minimum cross-sectional throat area at a smaller end thereof, each said throat in each conical nozzle being of a cross-sectional area designed to pass through each said throat at sonic speed an equal partial portion of said chosen mass flow of said compressible fluid, and with a total of all said partial portions of said compressible fluid through all said conical nozzles taken together being equal to said chosen mass flow of said compressible fluid,(e) said chosen mass flow of said compressible fluid exiting said conical nozzles into said inner fluid flow chamber at sonic speed and thus exerting a thrust on said rotor as said mass flow of said compressible fluid passes out from said conical nozzles and into said inner fluid flow chamber, a direction of said thrust being offset from said axis of rotation of said rotor at said designed radius from said axis of rotation of said rotor and thus exerting a torque on said rotor, said torque causing said rotor to rotate in an opposite direction to the direction of said conical nozzle exit flow into said inner fluid flow chamber, said rotor thereby acquiring by reaction force a rotational energy from said thrust of an accelerated fluid flow in said conical nozzle,(f) said inner fluid flow chamber having a downstream exit port of cross-sectional area not less than a combined throat area of said conical nozzles taken together, said mass fluid flow then exiting from said inner fluid flow chamber through said downstream exit port into a flow diffuser, said flow diffuser decelerating said compressible fluid flow and leading it towards a total flow exit port. 2. The method as in claim 1 wherein said compressible fluid is atmospheric air and said chosen mass flow of fluid is a mass flow of air. 3. An apparatus for efficiently generating and extracting power from a chosen mass flow of air, comprising: a rotor, a flow diffuser, and a vacuum pump, said rotor being cylindrical and being mounted on a longitudinal central shaft or axle at said rotor's longitudinal axis of rotation, said rotor having a set of two or more inflow conical nozzles molded, cast, machined or otherwise formed into said rotor, each said conical nozzle having a minimum cross-sectional throat area designed to pass through each said throat area of each said conical nozzle an equal portion of said chosen mass flow of air at sonic speed, said conical nozzles being circumferentially and symmetrically situated in said rotor, said set of conical nozzles being situated in a same plane of rotation in said rotor, said plane of rotation of said set of conical nozzles being at right angles to an axis of rotation of said rotor, each said conical nozzle having a respective larger flow entrance port situated on an outside rim of said rotor, each said conical nozzle leading through said rotor so that a respective smaller end's exit port of each said conical nozzle opens into a central, cylindrical inner air flow chamber of designed radius inside said rotor, each said conical nozzle being aligned in said same plane of rotation so as to be essentially tangent at said exit port to said inner air flow chamber at said designed radial distance from said longitudinal axis of rotation of said rotor,said mass flow of air exerting a large thrust force on said rotor when said mass flow of air accelerates within said set of conical nozzles to sonic speed and then enters said inner air flow chamber in said rotor, said thrust force also exerting a torque on said rotor as said mass flow of air enters said inner air chamber tangentially and at said designed radial distance from said longitudinal axis of rotation of said rotor, said rotor thus acquiring rotational power from said thrust force and said torque of said mass flow of air, said rotational power then being exportable to the exterior for useful work by coupling said rotor to a rotary power take-off,said inner air flow chamber having an axial circular exit flow port of approximately a same area as a sum total area of each respective inner exit opening leading into said inner air flow chamber of said rotor, said exit flow port in rotating said inner air flow chamber being mated and aligned to a non-rotating, tubular flow diffuser connected to a vacuum pump, said vacuum pump inducing and sustaining said chosen mass flow of air through said apparatus,said flow diffuser comprising a non-rotating cylindrical flow tube aligned to receive the high speed said mass flow of air exiting from said rotor's central inner air flow chamber and to then decelerate said mass flow of air efficiently to match said vacuum pump's intake flow speed, a length of said diffuser tube being designed to efficiently bring about said deceleration of said mass flow of air, said tubular flow diffuser having a tube diameter matching a diameter of said exit flow port of said inner air flow chamber, said tubular flow diffuser being aligned so as to receive and conduct the decelerating said mass flow from said exit flow port of said inner air flow air chamber towards and into said vacuum pump to which said tubular flow diffuser is connected, said vacuum pump having a flow capability to enable it to draw said chosen mass flow of air into and through said apparatus and then to discharge it back into the ambient atmosphere through an exit port of said vacuum pump,an air gap between the rotating said exit flow port of said inner air flow chamber and the non-rotating tube of said tubular air diffuser is kept to a designed minimum practical size in order to minimize leakage of ambient atmospheric air through said air gap into said mass air flow of said apparatus. 4. The apparatus as in claim 3, wherein a flow tube of said tubular flow diffuser is fitted with a grooved and tapered exit plug to assist in efficient deceleration of the high speed air flow exiting from said inner air flow chamber of said rotor, said exit plug having a grooved upstream flow portion and a conical tapered downstream flow portion, said exit plug being mounted in said flow diffuser's said flow tube by two or more mounting and centering pins holding said exit plug securely attached to said tubular flow diffuser so that said upstream grooved portion of said exit plug extends beyond the flow tube, and said tapered downstream flows portion of said exit plug is within said flow tube, said flow diffuser tube being aligned to, and mated closely to, said exit port of said inner air flow chamber so that said upstream grooved portion of said exit plug extends beyond the upstream end of said diffuser and into said inner air flow chamber but without making any physical contact between said grooved portion of said exit plug and rotating said inner air flow chamber and thus leaving a small air gap between non-rotating said diffuser's upstream end with its said exit plug and said inner air flow chamber which is rotating in said rotor.
