LM317T Voltage Regulator with Pass Transistor

Little Bedini motor and BIG solar panel running indoors with just ambient light and no batteries. Light energy is being controlled by a "step down adjustable voltage regulator" which allows energy to build up in a large capacitor before it feeds the motor. Energy coming off the collasping magnetic field of the motor drive coil is recycled back into the motor.
