A method for converting heat to electricity by exploiting changes in spontaneous polarization that occur in electrically polarizable materials is described. The method uses an internally generated field to achieve poling during cycling. The internal poling field is produced by retaining residual free charges on the electrodes at the appropriate point of each cycle.

The method is not limited to a specific thermodynamic cycle and can be used with any thermodynamic cycle for converting heat to electricity by thermally cycling electrically polarizable materials. The electrical energy generated can be used in various applications or stored for later use. An apparatus for converting heat to electricity is also described.

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. After the driven magnet passes the driver magnet, their like poles repel, also accelerating the disk. When the two permanent magnets are in close proximity, such that repulsion between like poles would decelerate the disk, an electromagnet is engaged between the two permanent to counteract this counterproductive force. One or more coils generate electricity through electromagnetic induction when the driven magnet passes them. A portion of this electricity powers the electromagnet, and the balance is the net energy generated.
