Abstract
Abstract A linear motion electric power generator. A rare earth magnet and a coil are positioned to move linearly back and forth relative to each other. The movement of the coil in the field of the magnet generates a current in the coil. Springless orientation means are provided to maintain a neutral position about which the relative motion occurs.
