Abstract:
1. An apparatus comprising: an elongated shaft defining a longitudinal axis of rotation; at least one rechargeable battery comprising at least one cell having a positive and negative terminal, the at least one battery mounted substantially coaxially with respect to the shaft; one or more magnets for providing a magnetic flux field; a rotor comprising an electrically conductive portion having an inner diameter conductive connection surface and an outer diameter conductive connection surface, the rotor mounted coaxially in communication with the shaft, wherein the rotor is operable to rotate in the magnetic flux field; at least one positive output electrode operable for selective electrical communication with at least one of the battery cell positive terminal, the rotor inner diameter conductive connection surface, or the rotor outer diameter conductive connection surface, wherein the at least one positive output electrode is stationary relative to the rotating shaft; at least one negative output electrode operable for selective electrical communication with at least one of the battery cell negative terminal, the rotor outer diameter conductive connection surface, or the rotor inner diameter conductive connection surface, wherein the at least one negative output electrode is stationary relative to the rotating shaft; and a connection system comprising one or more brushes for electrically connecting one or more of the rotor conductive connection surfaces or the battery terminals with one or more of the output electrodes.
