Joytopiaminds Stirling Engine Model, 16-Cylinder Butane-Powered Hot-Air Swashplate Stirling Engine with Stainless Steel and Solid Wood Construction for Physics and Science Experiment

【Industrial-Grade Design】Features 16 cylinders (8 heating + 8 cooling pipes) with a polished stainless steel swash plate and solid wood base. Aerodynamic silver finish and floating bead piston mechanism showcase intricate engineering for collectors and enthusiasts 【Butane-Powered Efficiency】Runs on eco-friendly butane gas (not included) with adjustable flame control. Ignites in 30 seconds-preheat, spin the propeller, and watch the hot-air cycle convert thermal energy into smooth mechanical motion (no explosions, low noise) 【STEM Thermodynamics Demo】Illustrates isothermal compression/expansion, heat transfer, and external combustion principles. Ideal for classrooms, labs, or teens 15+ to explore energy conversion, aerodynamics, and altitude efficiency effects ⚠️【Safety-First Operation】Includes step-by-step ignition/cooling guidelines. Natural cooling required before touching stainless steel heating tubes (21.5x10x16.5cm). Durable construction ensures long-term use with minimal maintenance (check flywheel smoothness, clean cylinders) 【Premium Display & Gift】Combines educational value with steampunk aesthetics. Perfect for engineers, teachers, or as a high-altitude-compatible decor piece. Includes manual for easy setup-no electrical parts, just mesmerizing physics in action, Manufacturer: Joytopiaminds
