How to make a Stirling engine using a tomato paste can and other household items. This is a single cylinder design or beta configuration. I start out with an overview of the design and a quick explanation of how the Stirling engine works. Then I go step-by-step through its construction, followed by it running and then some construction tips.
This one uses a balloon instead of a piston. It uses balsa wood for the displacer cylinder, coat hanger wire for the crankshaft along with a paperclip, a thread to connect the displacer to the paperclip, and a wooden flywheel. The connecting rods are attached to the diaphragm using thumbtacks.
