Abstract
A harvesting system that includes a dynamo with a rotor and a stator, a push magnet that is attached to the rotor or is a part of it, a moving magnet that moves from a first position to a second position, and a push back magnet. The repulsive magnetic force that is exerted by the moving magnet on the push magnet in the second position is greater than that force in the first position. The moving magnet moves from the first position to the second position and causes the rotor to rotate from a dynamo first position to a dynamo second position that causes the dynamo to produce current. When the moving magnet moves back to the first position the dynamo returns to its first position due to magnetic force that the push back magnet exerts on the push magnet.
