This a Stirling engine concept that I am developing as part of my Masters of engineering degree at the university of Canterbury (New Zealand).
The displacer, shown at the right, is a segment of a third of a cylinder, which is rotated back and forth by an electric motor, forcing air through the heat exchangers and regenerator (shown as red for hot exchanger, blue for cold exchanger, and green for regenerator. The heated or cooled air pushes out or sucks in the power piston which turns the crank and flywheel. Estimated power output of 1kW at temperature difference of less than 200 degrees C. It is quite large, about 2m x 1m footprint size.
