Congratulations!!! If your idea works, you have discovered the key to perpetual motion.----Need more electricity?---just run a second alternator off an electric motor. Think about what your saying!!!! Its a law of physics that you can't get something for nothing. The more power you use to run a second alternator off an electric motor, the higher the demand on your electrical system goes. If you are not carefull you will be like the legendary FUFU bird, that flies in ever diminishing circles untill it flies up its own butt and disapears.
