NOVELTY - The ferroelectric device (600) has a thermal energy which is subsequently added to the layers (610) of electrically polarizable material. The electrodes (622,624) are connected across the load. The electrical energy corresponding to the generated screening charges on the pair of electrodes is output to the load. The electrically polarizable material exhibits spontaneous polarization. The spontaneous polarization exhibited by the electrically polarizable material is less than the spontaneous polarization exhibited by the electrically polarizable material.    USE - Ferroelectric device for converting heat to electrical energy. Uses include but are not limited for bottoming up thermal power plants, converting thermal energy to electricity at power plants, generating electric power from geothermal energy sources, e.g., passive geothermal heating and cooling systems, generating electric power from heat provided by solar energy, generating distributed power with portable quasi-portable generators using predetermined heat sources and operating on predetermine scale, converting power waste heat from industrial and mining to power, producing electric power for diesel electric locomotives, generating power from ocean thermal gradients, and generating electricity for personal or medical use from body heat.    ADVANTAGE - Improves usage of spontaneous polarization for generating electricity from thermal energy since the spontaneous polarization exhibited by the electrically polarizable material is less than the spontaneous polarization exhibited by the electrically polarizable material. Permits the removal and use of the electrical energy generated by the spontaneous polarization that occurs when the material is in the ferroelectric phase since the electrical energy corresponding to the generated screening charges on the pair of electrodes is output to the load while the electrically polarizable material exhibits spontaneous polarization.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for converting heat to electric energy.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross sectional view of the ferroelectric device for converting heat to electrical energy.
