ABSTRACT:
A Savonius vertical axis wind turbine rotor, that is effective yet relatively easy to manufacture, includes spokes, vanes, and fasteners. Each spoke has a hub having a central opening, three arcuate ribs extending radially outwardly from the hub with inner (concave) and outer (convex) surfaces, and channels defined in at least one of the inner and outer surfaces. The vanes of sheet material generally conform to an inner or outer surface of a rib and have openings aligned with the channels. First fasteners pass through the openings and cooperate with second fasteners in the channels. Two of the spoke pieces may be joined by a bridging piece, and two spoke pieces by a clamp. A Savonius or helical rotor includes a generator, and a drive connecting the generator and rotor. The drive automatically increases the effective gear ratio between the generator and rotor as the speed of rotation increases.
