A Stirling engine which uses a dual pressure shell surrounding the high pressure and temperature engine components. Space between the shells is fill ed with an incompressible and insulating liquid material, such as a liquid salt . The liquid may have a filler material to prevent excessive movement. The liquid provides a time varying pressure field, driven by the pressure variations in the Stirling engine working fluid, which cancels the pressure differential on heat transfer tubing. A continuous heat extraction burner reduces flame temperature and nitrous oxide emissions from the burner. The combination described provides a Stirling engine that operates at significantly higher temperatures and pressures relative to existing technology.
