Abstract:
1. A wind turbine assembly for generating electricity, comprising: a turbine wheel support member, a wind turbine wheel mounted on said turbine wheel support member, said wind turbine wheel including a laterally extending central axis of rotation, a circular perimeter rim concentric with and rotatable about said central axis of rotation, and a circular intermediate rim concentric with said perimeter rim and positioned between said perimeter rim and said central axis of rotation and rotatable about said central axis of rotation, intermediate sail wings supported between said central axis of rotation and said circular intermediate rim, and outer sail wings supported between said circular intermediate rim and said circular perimeter rim, an electrical generator mounted in engagement with one of said circular intermediate rim and said circular perimeter rim for generating electricity in response to the rotation of said wind turbine wheel, a movable support configured for supporting said electrical generator and for moving said electrical generator in response to a change in the axial position of said one of said circular intermediate rim and said circular perimeter rim at the electrical generator, and a positioning wheel carried by said movable support and in contact with one of said perimeter rim and said intermediate rim for moving said movable support in response to the change of position of the circular rim at said movable support.
