Abstract
A spray-actuated heat engine comprises an expandable volume chamber containing an operating fluid in gas form, a reservoir holding a heat transfer fluid in liquid form, a pump that pumps the heat transfer fluid from the reservoir to the chamber, and a piping system through which the heat transfer fluid is configured to flow. The piping system is in fluid communication with a heat source for heating the heat transfer fluid to obtain a high temperature and is in fluid communication with a cold source for removing heat from the heat transfer fluid to obtain a low temperature. The heat transfer fluid at the high temperature is selectively sprayed into the expandable volume to mix with and expand the operating fluid, and the heat transfer fluid at the low temperature is selectively sprayed into the expandable volume to mix with and contract the operating fluid.
