         2 . The cementing head of  claim 1 , further comprising at least one torque converter disposed on the rotating body. 
     
     
         3 . The cementing head of  claim 2 , wherein the torque converter is electrically connected to the battery. 
     
     
         4 . The cementing head of  claim 2 , wherein the torque converter is electrically connected to the armature. 
     
     
         5 . The cementing head of  claim 2 , wherein the torque converter is electrically connected to the battery and the armature. 
     
     
         6 . The cementing head of  claim 1 , further comprising a swivel disposed on the armature, wherein the wire is connected to the swivel. 
     
     
         7 . The cementing head of  claim 1 , further comprising a heat jacket disposed over the battery. 
     
     
         8 . The cementing head of  claim 1 , further comprising a radio frequency receiver/transceiver disposed on the rotating body. 
     
     
         9 . The cementing head of  claim 1 , wherein the toothed ring comprises a plurality of magnets. 
     
     
         10 . The cementing head of  claim 6 , wherein the armature comprises a coil of wire. 
     
     
         11 . A cementing head comprising:
 a stationary body comprising an armature;   a rotating body disposed at least partially inside the armature;   a battery disposed on the rotating body; and   a wire connected to the armature and the battery.   
     
     
         12 . The cementing head of  claim 11 , further comprising at least one torque converter disposed on the rotating body. 
     
     
         13 . The cementing head of  claim 12 , wherein the torque converter is electrically connected to the battery. 
     
     
         14 . The cementing head of  claim 12 , wherein the torque converter is electrically connected to the armature. 
     
     
         15 . The cementing head of  claim 12 , wherein the torque converter is electrically connected to the battery and the armature. 
     
     
         16 . The cementing head of  claim 11 , further comprising a heat jacket disposed over the battery. 
     
     
         17 . The cementing head of  claim 11 , further comprising a radio frequency receiver/transceiver disposed on the rotating body. 
     
     
         18 . The cementing head of  claim 11 , wherein the rotating body comprises a plurality of magnets. 
     
     
         19 . A method of generating electrical power, the method comprising:
 disposing a cementing head on a well head, the cementing head comprising a rotating body, an armature, a stationary body, and a battery;   actuating the rotating body;   generating an electrical voltage in the armature; and   transferring the electrical voltage from the armature to the battery.   
     
     
         20 . The method of  claim 19 , further comprising:
 transferring the electrical voltage to a torque converter; and   actuating a cementing valve on the cementing head.
