Low Temperature Stirling Engine Model

Stirling engine is a nice education model for students and teachers. It can help to better understand the working principle.   How it Works A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work. A Great Explanation Teacher can make the explaining process much straightforward and students can better understand its principle. Safe Opeartion Run freely on the top of a cup of hot water, no need to fire a alcohol lamp,safer for children. Operating Requirement Start temperature difference between the product bottom contact and circumstance should be greater than 25℃.   Easy to Use Gently flip the wheel, then it can run itself. Considerate Design Exquisite frosted plunger can avoid steam leakage and the reduce abrasion. Note: If the friction between flywheel and support is big, please use a little graphite dry lube qu
