Description Stirling Motor Hot Air Model Engine Physics Science Toy Electricity DIY J Description: Hot Air Stirling Engine Model Kit for Physics Assembly Teaching Aids Educational Toys; Burning an alcohol lamp for a while, the expansion of the air in the tube will work jako medium to drive the pistons and flywheel, then the expanding air will be cooled in the cold chamber Since this process will circulate repeatedly, the flywheel will operate continuously Im hotter the pipe, the faster the flywheel works Various interesting! Great for developing students' interest in physics, more intuitive and easy to understand how heat energy is converted into mechanical work What is a Stirling engine? A Stirling engine is a heat engine that operates by cyclically compressing and expanding air or other gas at different temperatures so that there is a net conversion of heat energy to mechanical work Specification: Item name: stirling engine model! Materials: stainless steel glass Package includes: 1-piece model of a stirling engine!
