Abstract: A flywheel is provided in combination with a hybrid machine, wherein said flywheel comprises, in a radial direction, from inward to outward, an inner turbine, an intermediate compressor, and an outer array of magnets. The turbine cooperates with said hybrid machine to spin faster when said machine decelerates, and slower when said machine accelerates. An inner turbine drives both said intermediate compressor and said hybrid machine. The outer array of magnets is driven by said hybrid machine to accelerate the flywheel to accelerate the flywheel during braking of said hybrid machine. Said hybrid machine communicates with said flywheel to house it and render energy from it, in a hybrid manner such that energy is stored in a pressure or electrical storage mode, or both pressure and electrical storage mode, to effect a regenerative mode that attains low fuel consumption.
