Abstract: A wind turbine device may include four wings. A first wing may include a first leading edge and a first trailing edge, and a second wing may include a second leading edge a second trailing edge. The first and second leading edges may be positioned on opposite sides of the axis of rotation, the first and second trailing edges may be positioned on opposite sides of the axis of rotation, and the first and second leading edges may be positioned relatively closer to the axis of rotation than the first and second trailing edges. A third wing may include a third leading edge and a third trailing edge, and a fourth wing may include a fourth leading edge and a fourth trailing edge. The third and fourth trailing edges may be each positioned proximate to the axis of rotation and positioned on opposite sides of the axis of rotation.
