Multicolor lighting powered by heat - The Stirling engine model converts heat into motion and powers a small generator that lights multicolor LEDs, providing a vivid, visible demonstration of energy conversion for learners. Premium construction - Brushed aluminum alloy base plate. - CNC-machined shell frame with a sandblasted finish for a robust, attractive display suitable for educational use. Reliable components - Stainless steel connecting rods for maximum strength and durability. - Thickened glass heater cylinder for efficient heat retention, enabling longer heating cycles and repeated demonstrations without power loss. User-friendly operation - Easy to use in classroom settings. - Heating time of 60 to 120 seconds; after heating, the wheel can be turned with minimal effort to observe the engine in action. Use scenarios - Classroom demonstrations of thermodynamics and energy conversion for students. - Science fairs or educational exhibits to illustrate heat-to-light energy conversion. - Home or maker space projects for ongoing physics experiments and STEM learning.
