ABSTRACT:
A wind power system according to the preferred embodiment of the present invention is shown as including a vertically orientated main shaft. The wind power system further includes, in its preferred form, first and second horizontally orientated main frames, with the first frame including a plurality of vanes defining a first set of vanes and an equal number of vanes defining a second set of vanes located diametrically opposite each other about the main shaft. Similarly, the second horizontally orientated main frame includes a third set and a fourth set of vanes. Preferably, the vanes are flat and rectangular in shape and are pivotal about one of their vertical edges by a shaft pivotally mounted to the main frame between a first, wind catching position and a second, wind releasing position. The vanes of the vane sets are maintained in the same relative position to each other. The first and second set of vanes and the third and fourth set of vanes are pivotally related to each other such that when one set of vanes is in the first position, the other set of vanes is in their second position. In the most preferred form of the present invention, wheel assemblies are further provided attached to the main frames for rolling support on a generally horizontally disposed support surface for reducing the cantilever forces placed upon the main shaft.
