Abstract:
1. An apparatus comprising: an elongated shaft defining a longitudinal axis of rotation; at least one rechargeable battery; at least one magnet for providing a magnetic flux field, wherein the at least one magnet comprises a stator coupled to an approximate center location of the at least one magnet, the stator comprising one or more magnets having a first respective diameter that is smaller than a second respective diameter of the at least one magnet, wherein a north end of a first magnet of the one or more magnets is directed toward a south end of a second magnet of the one or more magnets, and wherein the south end of the first magnet is directed toward a north end of a third magnet of the one or more magnets; at least one rotor comprising an electrically conductive portion, the at least one rotor mounted coaxially in communication with the shaft, wherein the at least one rotor is operable to rotate in the magnetic flux field; and at least one electrical connection for electrical communication with at least one of the at least one rechargeable battery or the electrically conductive portion of the at least one rotor.
