Color: Set 16 Overview This Lshape Stirling engine combines visible mechanical motion with a builtin generator and an included USBpowered ambient night light. Fully assembled in a polished allmetal finish, it demonstrates heat to motion to electricity conversion while serving as a durable desk exhibit. Key benefits Visual, handson demonstration of thermodynamics and energy conversion: See the engine run and generate electricity as the flywheel turns. Ready to use out of the box: Delivered fully assembled so you can start experiments and demonstrations immediately. Functional lighting feature: The builtin generator lets you power the included ambient night light via USB for an engaging display of practical output. Durable, precision construction: Made from stainless steel and aluminum alloy with a metallic luster for both smooth operation and longlasting appearance. STEM learning tool: Designed for ages 15 and up to support education in mechanics, thermodynamics, and basic electricity. Features and function Engine type: Lshape Stirling engine with integrated generator. Materials: Stainless steel and aluminum alloy, precisionmachined components. Finish: Allsilver appearance with surface treatment for enhanced metallic luster. Power and compatibility: Includes a USB cable and an ambient night light. The generator output is intended to power the supplied light and is compatible with standard USB power inputs for demonstration purposes. Fuel and operation: Uses alcohol in the dedicated lamp holder. To operate, place on a level surface, add alcohol to the lamp holder, preheat, and spin the flywheel to observe operation and power generation. Assembly: Supplied fully assembled for immediate use. What makes it stand out Integrated generator plus a usable ambient light makes the thermodynamic process directly observable and useful. precision metal parts produce smooth, reliable motion and a professional industrial look suitable for display. No assembly required reduces barriers to handson experimentation and classroom use. Practical use scenarios Desk display and conversation piece: Place on a desk or shelf to demonstrate classic mechanics and provide soft ambient lighting powered by the engine. Classroom or workshop demonstration: Use during physics or engineering lessons to show Stirling engine principles, heat transfer, and simple electricity generation. Hobby and maker projects: Incorporate into a small demonstration setup for modelmaking, science fairs, or experimentation with thermal engines. Operation notes Intended for educational and demonstration use. Follow basic precautions when handling fuel and open flame during preheating. used on a stable, level surface to ensure consistent operation. Recommended for ages 15 and up. This model offers a compact, readytouse combination of mechanical motion, precise metal craftsmanship, and a practical lighting demonstration that supports learning and showcases energy conversion in a single unit.
