    Patent number: 8354759
    Abstract: A wind powered apparatus (or wind turbine) having two sets of counter rotating blades. Both sets of blades are connected to an alternator and are operable to rotate the stator and rotor thereof in opposite directions relative to one another, thereby doubling their relative speed. The apparatus is equipped with a conical front nose piece having a blunt tip that co-operates with the first and second sets of blades to improve performance of the apparatus by affecting its orientation and the rotational speed of the blades.
