One or more wheel structures are rotatably attached to the horizontal axle. Each wheel structure includes a rim, a hub, and a plurality of stays extending between and attached to the rim and hub. A plurality of jib sails are attached to each wheel framework in a manner adapted to cause the wheel to rotate about the axle when the wind blows against the sails. A positioning vane is rotatably attached to the downwind end of the axle and is adapted to point the upwind end of the axle into the wind when the wind blows.
