The disclosed wind turbine is designed to optimize power output at a given wind velocity without corresponding increases in cost. The rotor carries a plurality of vertical vanes arranged at an acute angle to diametric lines through the rotor and the inner edges of the vanes, which are spaced from the rotor center. Each vane carries a plurality of fins extending on opposite sides of the vanes. In one embodiment, a wind-collecting shroud is movable to position an open side thereof in the upwind direction and is shaped to direct the wind more efficiently toward the vanes and fins. In a second embodiment, each vane is bent on a vertical axis to include two portions, at least the inner of which carries wind-collecting fins, at different angles to the rotor diameter, and no shroud is used.
