LM317T Voltage Regulator with Pass Transistor

This is a simple science project style demonstration, on how a motor can be a generator. I am using a DC motor that I salvaged out of a Wal Mart toy scooter. It is a permanent magnet motor, and very efficient as a generator. If you were to put a regulator and a DC to AC inverter with it, you could get a usable amount of electricity.
