This is a Bedini motor running on one AA rechargable battery. Super capacitors are placed on the charging side of the motor and recycle their energy back into a permanent magnet motor that helps drive the device. This is not a self-runner or charger. Its just a pulse motor using the Bedini electronic circuit to drive it as long as it can on as little energy as possible. The motor was test run for 14 hours then I stopped it. The beginning battery voltage was 1.34 volts and the ending voltage was 1.23 volts with a 4 ohm load applied.
