Home made twin-cylinder steam engine running on live steam

Check out my brand new 2015 model and also my Steam Powered Christmas Tree!! This is the prototype version of my homemade twin cylinder, double acting steam engine operating on live steam on a propane-fired boiler. It is hooked up to a small generator, lighting up a few high intensity LEDs. The two cylinders are offset by 90 degrees, providing constant torque and allowing it to self-start. Bore: 14.3 mm Stroke: 20 mm D
