Claims
- 1. A wind turbine apparatus, comprising:
- a housing assembly which includes an upper housing surface having a leading edge, a curved portion extending backward from the leading edge, a straight portion extending backward from said curved portion, and a trailing edge located at a rear end of said straight portion, said upper housing surface being contoured so as to create a venturi action and exert a reduced pressure at said trailing edge as wind flows across said upper housing surface from said leading edge, across said curved portion and across said straight portion to said trailing edge, wherein said housing assembly also serves as a housing for an electrical generator and a battery bank,
- a vane assembly supported on a horizontal axle in a location such that vanes of said vane assembly are responsive to wind blowing in a direction from said leading edge to said trailing edge of said upper housing surface and such that said vanes are also exposed to reduced pressure near said trailing edge, whereby said vane assembly is caused to rotate on said horizontal axle, and
- a base assembly for supporting said housing assembly and said vane assembly.
- 2. The apparatus described in claim 1 wherein:
- said base assembly includes a circular guide assembly, and
- said housing assembly includes a guide-contacting portion for riding on said circular guide assembly in a circular movement.
- 3. The apparatus described in claim 2 wherein:
- said circular guide assembly includes a flange, and
- said guide-contacting portion includes a guide wheel, supported by said housing assembly, for rolling against said circular guide assembly.
- 4. The apparatus described in claim 1, further including:
- a wind indicator assembly for indicating wind direction.
- 5. The apparatus described in claim 1 wherein said vane assembly includes:
- a plurality of vanes,
- a rim for supporting said vanes,
- a plurality of spokes for supporting said rim, and
- a horizontal axle for supporting said spokes.
- 6. The apparatus described in claim 1, further including:
- an adjustable-pitch vane assembly for adjusting pitch of a vane with respect to wind contacting said vanes.
