A wind turbine is disclosed. Various embodiments of the wind turbine have a turbine rotator assembly that, when rotated by the wind, provides a rotational input motion to a power generation unit. The turbine rotator assembly may include a central rotator bearing and an outer ring. A plurality of flexible fins are mounted in tension between the outer ring and the central rotator bearing such that the fins are able to flex when contacted by wind at certain wind speeds. The fins may be mounted at an angle and at a twisted configuration to facilitate flexing of the turbine rotator assembly in a direction that is opposite to the direction in which the wind is blowing. Various embodiments employ electrical generator units and other embodiments employ hydraulic pump and motor arrangements that are coupled to an electrical generator.
