That is to say, as permanent magnet 46 of pendulum arm 38 approaches an operable magnetic field element such as electromagnetic 72, a magnetic field of electromagnet 72 is generated to pull the magnetic field of permanent magnet 46.

Once rotor swings downwardly, as illustrated on FIG. 8, passed the center point of coil 168, coil 168 is activated and produces a magnetic field of the same polarity as permanent magnet 164 at the end of arm 162. As shown in FIG.

  • the activation of coil 168 and the momentum of arm 162 will allow arm 162 to make yet another 360 degree turn.
  • coil 168 is deactivated once arm 162 and permanent magnet 164 pass over the same, but is again activated once arm 162 and permanent magnet 164 reach the center line or a point just pass the center line of coil 168.
  • FIG. 14 illustrates such relationship in a greater detail where a proximity switch 176 detects the presence of arm 162 and permanent magnet 164 above magnetic coil 168.
  • Relay 178 then allows the passage of DC power from a source 180 to magnetic coil 168 to produce the magnetic field which repels and pushes arm 162 and permanent magnet 164 along the direction indicated by directional arrow 174.
  • FIG. 13 illustrates the use of power generated by device IOC and passed from plurality of coils 124, in that a rectifier 182 may be used to convert AC power generated by device IOC to DC power. From rectifier 182, power passes to capacitor banks 184 and 186, alternately, by the use of voltage control relay 188 and regulatory switches 190 and 192. The power from capacitor banks 184 and 186 are then directed to DC battery 126 or to a user represented by
