A method and apparatus for generating electrical energy comprises driven permanent magnets mounted tangentially on a freely rotating disk attached to a relatively stationary platform, and driver permanent magnets mounted on the platform radially to the disk. As the disk rotates, as a driven magnet approaches a driver magnet, their respective opposite poles attract, accelerating the disk.
