• 🔱EXQUISITE DESIGN: The Stirling engine model features a delicate aluminum alloy texture that complements the classical beauty of the brass. The engine undergoes a special anodizing process that keeps it shining for a long time. The borosilicate glass cylinder and graphite power piston enable quiet and low-friction operation, while the hollow brass support and plastic screws on the bottom provide unexpectedly high insulation performance. 🔱EASY TO OPERATE : Place the HZZ92 low temperature Stirling engine on a freshly brewed cup of tea, hot coffee mug, cup of boiling water or ice, wait 20 seconds, gently turn the flywheel and it will run smoothly and quietly for over 30 minutes. The power piston makes a faint sound as the flywheel spins, which is even quieter than the ticking of your clock. Enjoy the display of the physical power mechanism and it will definitely make a great conversation piece on your desk. 🔱PHYSICS TOY: This HZZ92 Stirling engine model is suitable for classroom physics teaching and is ideal for demonstrating the basic principles and design art of the Stirling engine. It is not only a cool desktop piece, but also a relaxing stress-reliever that is perfect for placing on your office desk and becoming an excellent conversation tool. At the same time, it is also an impressive gift to give to family, friends, especially to engineering/physics/science enthusiasts. 🔱MAGIC PLAY: The HZZ92 Stirling engine converts small temperature differences into motion, as long as one aluminum plate is warmer than the other (about 15°C), the engine will run. It can run clockwise on a variety of heat sources, including boiling water, hot tea, hot coffee, digital TV boxes, ADSL modems, thermostatic plates (up to 60°C/140°F), etc. Place the Stirling engine on a large enough ice cube, wait 20 seconds, and gently toggle the flywheel by hand to fly along counterclockwise. 🔱STPCTOU'S BRAND QUALITY ASSURANCE - We provide 12-Month Warranty for any quality issues.
