Abstract
The invention is an energy transducer that utilizes a material's internal energy as an energy source by operating in a cycle where there is a net loss in the material's internal energy without the need to raise the temperature of the material above ambient temperature. The invention is accomplished by the use of selected materials in which the material's mechanical strain, magnetization or electric polarization can be controlled by cross coupling forces, and where the cross coupling coefficients are not equal to each other in finite operating regions.
Claims8
An energy transducer for the generation of useful work comprising a selected material in which the internal energy of said material 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 a variable primary force through which said useful work is generated, said material also being under the influence of a 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.
A method of generating useful work in which the internal energy of a selected material is used as an energy source, said method being operable in a cycle and being operable without the need to raise the temperature of said material above ambient temperature comprising the steps of:
- providing for a variable primary force to said material through which said useful work is generated;
- and
- providing for a variable secondary force which controls a physical property of said material to predetermined values, where 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.
A method as recited in claim 5 wherein:
- said secondary force being a mechanical stress.
