Patent ID: 7918648

Claim:
A windpower generator apparatus comprising: a horizontal shaft; a first arm extending outwardly of said shaft; a second arm extending outwardly of said shaft and radially spaced by 120° from said first arm; a third arm extending outwardly of said shaft and radially spaced by 120° from said first arm and by 120° from said second arm; a first plurality of vanes extending outwardly of said first arm, each of said first plurality of vanes being movable by gravity in a range only between a first position aligned with said first arm and a second position extending generally transverse to said first arm; a second plurality of vanes extending outwardly of said second arm, each of said second plurality of vanes movable by gravity in a range only between a first position aligned with said second arm and a second position extending transverse to said second arm; a third plurality of vanes extending outwardly of said third arm, each of said third plurality of vanes movable by gravity in a range only between a first position aligned with said third arm and a second position extending generally transverse to said third arm, said first plurality of vanes being in said first position when said plurality of vanes of said one of said second plurality of vanes and said third plurality of vanes is in said second position, said first plurality of vanes being in said first position when in a position above said shaft, said one of said second and third pluralities of vanes being in said second position when in a position below said shaft; and a generating means cooperative with said shaft for producing electrical energy relative to a rotation of said shaft.
