Patent ID: 8237325

Claim:
An energy transducer for the generation of useful work comprising a selected material having internal energy and in which there is a cross coupling between an energy conjugate physical property of a variable primary force and an energy conjugate physical property of a variable secondary force, said cross coupling being characterized by cross coupling coefficients that are not equal under conditions when said transducer is in operation, and in which said internal energy is used as an energy source, said transducer being operable in a cycle and being operable without the need to raise the temperature of said material above ambient temperature, said material being under the influence of said variable primary force through which said useful work is generated, said material also being under the influence of said variable secondary force which controls a physical property of said material to predetermined values, said property being an energy conjugate property of said primary force, wherein said primary force being an electric field; and said property being electric polarization.
