Patent ID: 7851937

Claim:
A wind-powered electrical assembly comprising: a wind-powered actuator assembly adapted to rotate about an axis in an actuating direction when subject to an operating wind; a spring assembly, the spring assembly having a shaft, a reel mounted to the shaft, a tape spring wound around the reel, a spring pawl mechanism operably arranged with the shaft, and a spring gear, the tape spring mounted on the reel such that when the shaft is moved in an operating direction, the reel rotates in the operating direction and the tape spring develops a return force, the return force urging the reel to move in a return direction, the return direction opposing the operating direction, and the spring pawl mechanism operably engaged with the shaft of the first gear to resist movement of the shaft in the return direction to cause the spring gear to rotate in the operating direction; an actuator gear train, the actuator gear train operably arranged with the wind-powered actuator and the shaft of the spring assembly to transfer the rotation of the wind-powered actuator to the spring assembly; an electrical generator, the electrical generator having a rotor; a generator gear train operably arranged with the spring gear of the spring assembly and the rotor of the electrical generator such that the rotor of the electrical generator rotates when the tape spring unwinds; and a rechargeable battery, the rechargeable battery electrically connected to the electrical generator.
