A low temperature differential Stirling engine includes a sealed elongate hollow container having a corresponding elongate cavity therein containing a gaseous working fluid and a displacer slidably mounted in the cavity. The displacer is translatable along the cavity. The container has a hot end and an opposite cold end. Translation of the displacer along the cavity forces the working fluid into the hot or cold ends sequentially according to a Stirling cycle. The hot end of the container has a power piston conduit. The conduit is in fluid communication with a power piston cylinder containing a power piston slidably mounted therein. Thus the conduit is in fluid communication between the working fluid in the cavity in the hot end of the container and the power piston cylinder so that heated expansion of the working fluid in the hot end of the container produces a power stroke of the piston. The displacer is mechanically decoupled from said power piston.
