Flywheel generator.

Faraday's disc permanent magnet device and I also add a flywheel. This is only a scheme. Flywheel is gathering energy to overcome Faraday's disc magnetic resistance. Part of energy is delivered to electric motor, the rest is predicted to power some external devices. The device is inspired and designed on the ideas of Bruce Depalma inventions.

The flywheel sustain rotation by its own inertial energy in this device, without this flywheel the entire device will stop due to friction and magnetic resistance of the disc. The flywheel should be heavy enough to sustain the rotation (not too big for electric motor capabilities, not too small thus the system could have insufficient inertial energy to work). Once it is propelled by the electric motor to a proper rotational speed, entire system will work partially and simultaneously with much less power consumption from the electric motor. It means that the energy delivered by electric motor to the system is needed only to sustain rotation, where energy from the flywheel should be sufficient to abate this energy requirements of the system, to the level in which it can sustain own working and additionally give away electric power to a load - some external electric receiver.  

Can we create free energy from inertial forces ? Application of heavy flywheel in electric motor and generator system coupled together may not seems to be plausible if we consider nowadays electric current production methods. However the system idea is not new, but whether is true, time will show. There're some interesting movies in YT in this topic, but not confirmed in real conditions. Reason can be simple, those projects are ended so quickly due to very small financial resources engaged in their construction.
