Abstract: The present invention relates to a donut-shaped power recycling device that harnesses wasted energy especially from Heating, Ventilation, Air Conditioning, and Refrigeration systems (HVACR) to be used as again as electrical and (or) mechanical energy. The device utilizes the effect of buoyancy due to gravity to generate a vortex that can pick up from the Coriolis Effect. The device comprises a donut-shaped stator, a donut-shaped rotor divided into a plurality of curved-shaped compartments; each having a rectangular-shaped opening at the outer circumference of the rotor; and wherein each of such openings has a plurality of power pickups, a cold gas inlet, a hot liquid inlet, a hot gas outlet, and a cold liquid outlet. The device can also have a bypass encountering the right hand side of said stator, and can further contain steam jets directed in an inclined angle towards said rotor.
