Patent ID: 8593009

Claim:
A power generation system ( 10 ) for generating electrical energy from wind, the system comprising, in combination: two similarly configured axles ( 14 ) rotatable about parallel vertical axes, each axle having a plurality of radially extending blades ( 16 ), the axles and blades being laterally displaced sufficiently wide so as to allow rotation of the axles and the blades without interfering with each other, the axles and blades being laterally displaced sufficiently narrow so as to allow counter rotation of the blades and axle when wind contacts the blades and moves with respect thereto, the space between the axles defining a central passageway there through for wind; a housing subassembly ( 20 ) encompassing the axles and blades, the housing subassembly having a concave front surface ( 22 ) with a front opening ( 24 ) for receiving wind, the wind from the front opening contacting the blades at forward locations, the housing subassembly having a convex rear surface ( 26 ) with a rear opening ( 28 ) for discharging wind, the housing subassembly having upper and lower surfaces ( 30 ), ( 32 ) encompassing the axles and the blades, the upper and lower surfaces having apertures ( 34 ) for rotatably receiving the axles, the front surface having lateral openings ( 36 ), each opening forming a supplemental passageway ( 38 ) for channeling supplemental wind to contact and move the blades, the wind from the supplemental passageways contacting the blades at rearward locations rotationally spaced from the forward locations, the housing assembly having screens ( 40 ), ( 42 ), ( 44 ) covering the openings; a levitation support for each axle, each levitation support including a lower extent of each axle extending beneath the lower surface of the housing subassembly, a fixed tubular retainer ( 48 ) rotatably receiving the axle, a disk shaped lower magnet ( 50 ) on an upper extent of each retainer and a disk shaped upper magnet ( 52 ) on each axle above each lower magnet, each magnet being a rare earth magnet in a repelling relationship with an associated magnet; and a chamber ( 56 ) encompassing the lower extent of each axle and its levitation assembly, a generator ( 58 ) within each chamber beneath its levitation assembly, a magnetic insulation shield ( 60 ) between each levitation assembly and its generator, a coupling between each axle and an associated generator whereby movement of the wind through the housing subassembly will rotate the axles to rotate the generators for creating electrical energy, the shaft being coupled to the housing whereby the shaft is laterally centered with respect to the housing with the majority of the mass of the housing being located behind the shaft.
