We all know that according to thermo-dynamics laws Perpetual motion machines are impossible to make.
( Perpetual motion is motion that continues indefinitely without any external source of energy.This is impossible to ever achieve because of friction and other sources of energy loss. A perpetual motion machine is a hypothetical machine that can do work indefinitely without an energy source. This kind of machine is impossible, as it would violate the first or second law of thermodynamics.)
But Prof. John Searl designed a generator called Searl Effect Generator (SEG) that can generate electrical energy without giving any energy,At least we don't have to give energy to it. SEG takes energy from environment as form of heat and gives continuous electric energy.
The SEG consists of 3 large ring type stators that are specially magnetized with patterns designed to generate continual motion of similarly magnetized cylindrical rotors. The rotors are free to rotate around the stator rings with mutually interactive eddy currents of induction that forms a frictionless magnetic bearings between moving parts. In the process, electrons pair up as bosons, accelerate to form electrical currents and thus are harnessed for their kinetic energy before they emitted out to the air again. This makes for an open energy cycle that extracts energy out the environment and consequently cools down the ambient air only for its inherent energy. It is a system that converts random energy at the quantum level into a coherent flow of electron currents. It is ideally suited for the World’s demand for green energy that is as benign to the biosphere as a solar cell or a even hydroelectric dam.
