Patent ID: 7944075

Claim:
A system for making and storing energy using wind power, said system comprising: (a) a support platform; (b) one or more turbine rotors on said support platform, each turbine rotor comprising: a rotatable vertical shaft extending from said platform; at least one bearing for said vertical shaft; and at least three rotor vanes disposed for rotation about said vertical shaft, each rotor vane being substantially box-shaped with four solid sides and a front and rear side disposed in a radial vertical plane, said front side being substantially open faced and said rear side having an opening covered by a flap that can be moved with a directional passage of wind through said rotor vane; (c) a heavily weighted device configured and disposed to move from a first low point to a second, raised point; (d) means for connecting said turbine rotors to said heavily weighted device for moving said heavily weighted device by wind rotation of said turbine rotors; and (e) means for extracting energy from said system when said heavily weighted device is allowed to return from said second, raised point to said first low point.
