         4 . The device of  claim 1 , further comprising a magnetic or mechanical coupling allowing removal of the generator for other uses. 
     
     
         5 . The device of  claim 1 , further comprising a gear-set to modify the speed of the generator relative to the rotational power source. 
     
     
         6 . The device of  claim 1 , further comprising a power conditioning circuit for the purpose of controlled charge and discharge of the energy storage system. 
     
     
         7 . The device of  claim 1 , adapted to enable the recovery of energy generated by human powered motion of parcels, carts, luggage, computer bags, or other pushed or pulled devices. 
     
     
         8 . A device, comprising:
 a rotor; and   a stator having a housing, a first portion of the housing defining a cavity in which the rotor is disposed, a second portion of the housing defining a path within which to wind an electrical conductor, the path having a first beveled side and a second beveled side and located about an outer perimeter of the cavity;   wherein the rotor is configured to be held stationary and the stator is configured to rotate about the rotor.   
     
     
         9 . A device, comprising:
 a stator having a coil and a housing defining an ellipsoidal path within which the coil is wound, the ellipsoidal path having a first beveled side and a second beveled side; and   a rotor disposed external to the stator.   
     
     
         10 . The device of  claim 9 , wherein the rotor is a first rotor, the device further comprising:
 a second rotor coupled to the first rotor;   wherein the housing of the stator defines a cavity within which the second rotor is disposed and supported to rotate about an axis common to the first rotor.   
     
     
         11 . The device of  claim 10 , wherein the first rotor and the second rotor are magnetically coupled. 
     
     
         12 . The device of  claim 10 , wherein the second rotor is an sphere including iron. 
     
     
         13 . The device of  claim 10 , wherein the second rotor is a spherical magnet. 
     
     
         14 . A device, comprising:
 a rotor; and   a stator having a plurality of winding housings, a first portion of the housings defining a cavity in which the rotor is disposed and supported to rotate about an axis, a second portion of the housings defining a plurality of paths within each of which one of the windings is wound, each path having a first beveled side and a second beveled side and located about an outer perimeter of the cavity, each path being angularly offset from another path by a predetermined rotation angle.   
     
     
         15 . The device of  claim 14 , wherein the rotor is a two-magnetic-pole spherical rotor. 
     
     
         16 . A device comprising:
 a rotor; and   a stator including a plurality of one-half turn elements.   
     
     
         17 . The device of  claim 16 , wherein the rotor is internal to the one-half turn elements. 
     
     
         18 . The device of  claim 16 , wherein the rotor is external to the one-half turn elements. 
     
     
         19 . The device of  claim 18 , further comprising an internal rotor, internal to the one-half turn elements. 
     
     
         20 . The device of  claim 16  wherein each one-half turn element has a trapezoidal cross-section. 
     
     
         21 . The device of  claim 16  further comprising a shorting ring electrically connecting one of the ends of the plurality of one-half turn elements.
