Abstract
A regenerative heat engine designed to produce power for the operation of equipment such as an artificial heart is disclosed. The heat engine includes a temperature control heat pipe located around the periphery of the engine cylinder and a temperature distribution heat pipe located around the periphery of the heat source. A flywheel and bellows seal is included as part of the displacer piston drive, and a flexure support is positioned on the hot end of the displacer piston to allow the piston to move longitudinally while restricting lateral motion.
