An electric energy storage and distribution system for a fluid-driven propeller, the propeller being connected to drive an AC generator, includes a planetary gear system by means of which rotation of the propeller is transferred to the AC generator motor, via a ring gear and a sun gear attached to a DC generator/motor, the DC generator/motor being connected to a battery. When the speed of the propeller is insufficient to drive the AC generator at a desired frequency and voltage, the DC motor is driven by the battery to either assist rotation of the propeller or the propeller can be braked such that the DC motor alone drives the AC generator. When an excess propeller speed is obtained, the propeller drives both the AC generator and the DC generator, the DC generator charging the battery. Conversely, when excess power is available through the power grid, the AC generator can be used as a motor to drive the DC generator via the ring gear, planetary gear, and sun gear to charge the battery.

An electrical energy storage and distribution system, comprising: a propeller rotatable in response to an external source of mechanical energy; an AC generator and a DC motor/generator, wherein the AC generator is mechanically connected to the propeller through a ring gear attached to a shaft of the AC generator and planetary gears rotatable about planetary gear axes fixed to the propeller, the planetary gear free to revolve around a sun gear, which in turn rotates around a central axis, the planetary gears thus revolving around the central axis as they rotate around respective said planetary gear axes, whereby when the sun gear is braked, all power from the propeller is transmitted to the AC generator via the planetary and ring gears; and wherein the DC motor/generator has a shaft attached to the sun gear such that, when the propeller is braked, rotation of the shaft is transmitted via the sun gear to the planetary gears, the ring gear and the AC generator, and such that when neither the shaft of the DC motor/generator nor the propeller is braked, power from both the DC motor/generator and propeller is transmitted to the AC generator, the rotation of the planetary gears about their own axes caused by rotation of the propeller and the revolution of the planetary gears about the central axis caused by rotation of the sun gear both contributing to rotation of the ring gear and therefore transmission of power to the AC generator, rotation of said ring gear and propeller also being capable of causing transmission of power through said planetary and sun gears to said DC motor/generator; and a battery for driving said DC motor/generator, said battery being connected to the motor/generator to receive a charging current from said motor/generator when said motor/generator is driven by said propeller or AC generator, said AC generator being capable of operating as an AC motor in response to excess capacity on a power grid to which the AC generator is connected, and to thereby drive said DC motor/generator in order to supply said excess capacity to the battery; wherein when the speed of the propeller is greater than that necessary to generate a desired output from said AC generator, power is transmitted from the propeller through the planetary gears to both the ring gear and the sun gear to drive the AC generator at a desired frequency and voltage and to also drive the DC motor/generator to produce electricity to charge the battery; and when battery charging is not desired, the propeller is braked and the AC generator is driven exclusively by the DC motor/generator acting as a motor; and when the propeller speed is higher than a predetermined speed, the DC motor/generator acts as a DC generator to charge the battery; and wherein the AC generator also operates as it motor when supplied with power from the power grid to thereby drive the DC motor/generator via said gears to charge said battery.
