Abstract: Provided are systems and methods for a wind-powered electrical generation and fluid pumping device, including: a drive shaft; a generator comprising a rotor, wherein the generator may be coupled to the drive shaft by means of the rotor; and at least one vane pair, the vane pair comprising ribs and a structural twist, wherein the at least one vane pair is attached to the drive shaft by screws and square washers and further wherein vane extensions may be attached to the at least one vane pair with rivets. The vertical wind-powered electrical generation device is also described. It utilizes unique improvements of shaft coupling (to generator and rotor), the strengthening of complete Savonius rotor system, and ease of assembly. The vane pairs may be a segmented Savonius rotor. They may also create a helix pattern as they are installed.
