In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
How is running a motor 24x7 which produces heat (wasted energy) to charge a bank of batteries using a generator and then converting to 110 or 220 via an inverter that also wastes energy more efficient than the elec company..

Indeed in the laws of physics, it sounded quite impossible to happen. Save the cost, of course, become the goal of many people in the mine. but when suggesting things that don't even make sense like this it will be impressed as a stupid hoax.
