Abstract

A reversible mechanical-thermal energy cell comprising: reversible intake and exhaust passages respectively leading to and from reversible rotatably connected rotary intake and exhaust volumetric periodically vanishing displacement devices of unequal rates of volumetric displacement, said rotary intake and exhaust volumetric displacements flowably connected by a reversible compression-expansion conduit, said conduit being in thermal communication with a thermal energy reservoir for containing matter subject to thermal change; and a compressible-expandible fluid reversibly traversing from said intake to said exhaust passage via said volumetric displacements and said conduit, said fluid subject to volumetric, pressure and thermal change in said conduit. Applicable in a range including thermal energy storage and retrieval, heating, cooling, cooking, refrigerating, and of fixed installation or portable.
