ABSTRACT:
A windpower generator apparatus has a horizontal shaft, a first arm extending outwardly of the shaft, a second arm extending outwardly of the shaft in spaced relationship to the first arm, a third arm extending outwardly of the shaft in spaced radial relationship to the first and second arms, a first plurality of vanes pivotally affixed to a first arm, a second plurality of vanes pivotally affixed to said second arm, a third plurality of vanes pivotally affixed to said third arm, and a generator cooperative with the shaft for producing electrical energy relative to a rotation of the shaft. Each of the vanes is movable between a first position aligned with the arm and a second position extending transverse to the arm. The vanes are movable between the first and second positions by actions of gravity during the rotation of the shaft.
