Patent ID: 8164213

Claim:
An orbital track wind turbine for generation of electrical energy from wind power, said wind turbine comprising: (a) a plurality of spaced vertical supports; (b) at least two parallel spaced circular tracks fixedly secured to said vertical supports, said circular tracks being coaxial with one another and positioned in parallel horizontal planes; (c) a plurality of trucks extending between said circular tracks, each of said trucks having at least two grooved rollers which partially surround said circular tracks and operate in rolling engagement therewith; (d) a circular power takeoff ring coaxial with said circular tracks, said circular power takeoff ring being attached to said truck and being rotatable in a horizontal plane about its central axis; (e) a plurality of vertical airfoils extending around said circular tracks, each of said airfoils being attached to a truck and said power takeoff ring; (f) one or more generators being rotatably connected to said power takeoff ring, whereby wind power striking the airfoils causes rotational movement of both the airfoils and attached power takeoff ring and conversion of wind generated rotation of the power takeoff ring and generators to electrical energy.
