Heat engine includes containers for hot and cold fluids, with interconnected, immersed gas vessels open at the base, executing vertical reciprocation

摘要

The apparatus includes containers (79, 80) for cold and hot fluids (3, 4). Two or more gas vessels (75, 76) have open bases and dip into the fluid in one or other of the containers. A gas line connects the vessels and heat storage material is provided on or in the gas line and/or the gas vessel. A controller is provided for up and down reciprocation of the gas vessels, which are immersed to differing extents.
