Perendev 300 kW Self-Running Electromagnetic Generator designed by Mike Brady will be introduced in May 2006. The motor drags energy from electromagnetic forces and is expected to cost you around 0.28 cents per kilowatt-hour.
Though the 350/400 kilograms generator requires a battery to start, but as soon as it kicks off providing 300 kW of electricity via an alternator, it takes it power from itself and also recharges the battery. It can run 100 homes churning out '110volt 3 phase or 380 volt 3 phase". The unit will be EMF shielded and gives out around 30 decibels of noise.
