A fixed horizontal axis-mounted wind turbine blade impelled by an independently rotating, pressure cambered fin includes a wind turbine blade comprised of a solid, rigid leading edge and trailing edges. The blade is triangular in shape, the base of the triangular blade is attached to a center, longitudinally fixed, horizontal, primary rotating axis and the point opposite the base is most distant from the horizontal rotating axis. The wind turbine blade base and length are aligned mutually perpendicular to the primary horizontal axis of rotation. A triangular fin is attached to the trailing edge of the blade end most distant from the base. The base of the attached fin is coincident to a secondary axis of rotation. The secondary axis of rotation allows the fin to rotate past either side of the plane of primary blade revolution in response to wind pressure. |
