Material: SUJ Alloy Steel, SUS, 6061 Aluminum Alloy Item Size: 21x13.2x10mm Cylinder Inner Diameter: 19mm Piston Stroke: 16mm Piston Diameter: 16mm Flywheel Diameter: 65mm Package List: 1 x Stirling Engine 2 x Alcohol Lamp 2 x Wick 5 x LED Note: 1️⃣ Do not touch the baked test tube and the metal connected to it, so as not to burn. 2️⃣ Do not add any lubricant to Stirling. 3️⃣ Please adopt 95% high-grade alcohol to be the fuel to make sure the air tank can get more temperature and drive the stirling engine. 4️⃣ Please pay attention the temperature of candle's light is not powerful enough for this toy. TIPS: Spare parts offer available. Please message us to get offer if need any parts replacement.

? EASY OPERATION - Fill the alcohol burner with your 95% alcohol ( recommend this fuel, not more than 2/3 of the container) and light it. Let the light burn the round ended cylinder for about 20 seconds, then give the wheel a gently push, it will run like a charm. Sturdy and durable metal components ensure long operation, enjoy physical powertrain mechanism display.

? PERFECT INTERPRETATION OF ABILITY CONVERSION - This Stirling engine with generator perfectly illustrates the process of converting thermal energy into mechanical energy and mechanical energy into electrical energy. Because of the heat from high-grade alcohol, the engine will run madly and create the electricity.The dual cylinder engine is full of power and the voltage can reach 4-9V. The flywheels will rotate rapidly, making the generator's LED lights flickering wildly.

?EXCELLENT ARTWORK FOR ENGINEERING PHYSICS ENTHUSIASTS - It will be a great conversation starter for everyone around you; a cool desktop piece amazing your friends and colleagues; a great gadget to kill time when boring; a relaxing stress relief physics toy for people in the office; an impressive gift for your families, friends, especially for engineering/physics lovers. It can be used for teaching physics, great to display basic principles of a Stirling engine and to show the art of design.

?CNC MACHINED STIRLING ENGINE - Stirling engine is made of high quality aircraft aluminum alloy stainless steel brass SUJ2 bearing steel material through CNC machining process. All the parts have done surface treatment to avoid rusting,Oil-free. Ultra high hardness alloy with high-precision size enables those parts to be wear-resistant and interact with each other smoothly. strongly stable to keep 2 aluminum alloy flywheels perfectly in the right position.
