Compact Stirling engine model kit that combines clear mechanical demonstration with precise metal craftsmanship. Ideal as a decorative desk piece, a handson teaching aid, or a collectible for mechanical enthusiasts and model collectors. Key benefits Clear demonstration of the Stirling principle: an external combustion engine heated by an alcohol lamp that runs smoothly when the flywheel is gently started, making thermodynamic concepts visible and intuitive. Durable, quality construction: textured metal components and precision manufacturing deliver reliable movement and a satisfying mechanical feel. Longlasting heating element: thickened quartz glass tube resists thermal stress during extended demonstrations, reducing the risk of breakage. Ready for display and collection: compact dimensions and an included display base let you showcase the model on a desk, shelf, or in a collection case. Features and specifications Materials: metal and quartz glass for strength and heat resistance. Product dimensions: 11 x 6.5 x 6.5 cm. Function: external combustion Stirling engine operated with an alcohol lamp; smooth, quick rotation once started by gently pushing the flywheel. Design: miniature, precisionmachined metal parts with textured finish and a stable display base. Intended audience: mechanical enthusiasts, collectors, educators, and anyone interested in mechanical principles. Practical use scenarios Desk display and conversation piece: place on an office desk or shelf to demonstrate mechanical motion and spark discussion about engines and thermodynamics. Classroom demonstration: use as a visual teaching aid for physics or engineering lessons to illustrate heattomotion conversion and the Stirling cycle. Hobbyist experiment and collection: operate with an alcohol lamp for handson exploration of engine behavior, then display the model as part of a mechanical model collection. What makes it stand out Authentic Stirling operation in a compact, durable package that balances educational value and decorative appeal. Precision metal parts and a reinforced quartz glass tube provide both visual quality and operational reliability. Compact size and integrated base make it easy to display while keeping the focus on the working mechanism. Package considerations Small, precision parts require careful handling during operation and display. Designed for use with a small alcohol lamp as the heat source for operation. This Stirling engine model offers a practical, compact way to explore fundamental mechanical principles while serving as an attractive collectible or teaching tool.
