An orbital track wind turbine for generation of electrical energy from wind power is provided. The wind turbine includes a plurality of spaced vertical supports to which at least two parallel spaced circular tracks are fixedly secured. These circular tracks are coaxial with one another and are positioned in parallel horizontal planes. A plurality of trucks extend between the circular tracks, the trucks having at least two grooved rollers which partially surround the circular tracks and operate in rolling engagement therewith. A circular power takeoff ring is coaxial with said circular tracks, and the power takeoff ring is attached to the truck which is rotatable in a horizontal plane about its central axis. A plurality of vertical airfoils extends around the circular power takeoff ring, with each of the airfoils being attached to a truck and the power takeoff ring. One or more generators are connected to the power takeoff ring, thereby converting wind generated rotation of the power takeoff ring to electrical energy.
