Abstract
A Stirling-like system incorporating a heater, a displacer and a regenerator is intermittently coupled to an external system via valves, providing pneumatic power while ridding waste heat. The external system is commonly a Rankine cycle, sharing the working fluid of the Stirling-like system, and can be used for heat pumping, distillation and drying. The Stirling working fluid and the Rankine working fluid are the same material and are exchanged between the two systems. A dual Stirling-like system mates a heat engine with a heat pump, sharing the same pressure-containment, with the dual system intermittently coupled to external environments for convective exchange of heat and cold.
