Abstract
A Savonius vertical axis wind turbine rotor has at least three spokes, at least two vanes, and fasteners. Each spoke includes a hub with central opening and arcuate ribs integral with the hub and extending radially outwardly. Channels are defined in at least one surface of each rib. Vanes of sheet material generally conform to an inner or outer surface of the ribs and have openings aligned with the channels. First fasteners pass through the openings into the channels and cooperate with second fasteners provided within the channels. Each hub may define a clamp which cooperates with a shaft, the clamp including a radial slot in the hub communicating with the central opening and fastener receiving elements on opposite sides of the slot. The vanes may overlap the central opening so that there is spillover from one vane to the next when the rotor is rotated by the wind.
