This desk-size Stirling engine runs on heat from its alcohol burner: fill it with alcohol, light it, let the flame heat the glass cylinder for about 60-120 seconds, then give the flywheel a gentle push, per the listing. As it runs, it generates electricity that powers an attached multicolor LED. The base is brushed aluminum alloy, the frame is CNC-finished, the flywheel is aluminum alloy and the connecting rod is laser-cut stainless steel. Spare glass tubes and an O-ring are included. Alcohol fuel is not described as included.
A real heat engine you can watch run on your desk, turning a small flame into motion and light. It's a physics lesson and a conversation piece in one.
