Description: Balance stirling engine mini generator external combustion hot air engine education model kit. Burnning the alcohol lamp continuously, the expansion of air in the tube will work as a medium to run the piston and flywheel. With the help of the flywheels, heat energy will convert into mechanical work; mechanical work through small generator produces electricity to power a light bulb. Then the expanding air will be cooled in cold chamber; this process will be repeatedly circulating. Great educational toy, classroom or laboratory experimental teaching aids, cultivate children's interest in physics, more intuitive and easy to understand. What is Stirling Engine? A stirling engine is a heat engine that operated by cyclic compression and expansion of air or other gas at different temperatures, so that there will be a net conversion of heat energy to mechanical work. Specification: Item Name: Stirling Engine Model (Metel Base) Materials: Brushed Aluminum Alloy+Stainless Steel+Thickened Glass Color: Silver,Blue Size(L*W*H): Approx. 20*10*9cm / 7.87*3.93*3.54inch Flywheel Diameter: Approx. 5.3cm / 2.08inch Generating Voltage: 3-5V Experiment Type: Physical Package Includes: A Stirling Engine Model An Alcohol Lamp with Wick A Glass Cap (Need DIY Assembly) Note: Do not touch the baked test tube and the metal connected to it, so as not to burn. Long time light alcohol lamp, alcohol lamp can not easily touch, so as not to burn. Suitable for more than 8 years of age, 8 years of age need to operate under the guardianship of parents. When heating, do not touch the tube of alcohol lamp tube, wick combustion will produce moisture, if touched, may lead to tube cracking
