A power generator comprising a generator drivably attached to a turbine. The turbine comprises a shaft rotatably mounted to a frame. Support plates drivably engage the shaft and a plurality of blades are pivotably connected to the support plates. Each blade has a distal edge that is disposed adjacent the shaft when the blade is pivoted to a stopped position. During operation the blades revolve about the shaft axis. Each blade is held in the stopped position by the flow stream for a portion of the revolution and is pivoted away from the stopped position for the remainder of the revolution. In one embodiment, blade stops limit the outward pivot of the blades to improve efficiency. In another embodiment a second set of blades are provided and rotationally offset from the first blades. In another embodiments the support plates are configured as rotors for the generator.
