Abstract
A method and apparatus for producing electrical energy from a thermal dynamic cycle. The apparatus can include a heat exchange apparatus portion that allows for a large surface area for thermal energy collection while maintaining an efficiency of the thermal dynamic cycle engine. For example, a Stirling engine can include a large heater head portion that can be contained within the pressure vessel of the thermal dynamic engine yet maintain the selected size of the various pistons of the thermal dynamic cycle engine.
