Multi Coil system Introduction by John Bedini-Rather then get into a big discussion over what material is better for the rotor at this point, I want to point out a few things. As I said in the beginning this is a simple machine to just prove that you can have a machine that supplies mechanical energy to do something with no matter how small that is. It’s the first machine that runs does the work and charges a battery, it recovers all the waste energy in the circuit and supplies it to a secondary battery, don’t you wish you had a toy like that, because it is toy sized, but toys make “big machines”.
