STL-SGM Inline Four-Cylinder Hot Air Stirling Engine External Combustion Engine Power Generator Model

Features:

• Named after its inventor, Reverend Robert Stirling, this Stirling engine is a remarkable engineering feat.
• Powered by the expansion and contraction of gas through heating and cooling, this external combustion engine uses continuous fuel combustion relying on expanding air (or ammonia or hydrogen) to move the piston, which then cools in the cold chamber, creating a repeating cycle.
• Precisely CNC-machined from aluminum alloy, this exquisite model combines both texture and aesthetics with a gold electroplating finish. Comes with a wooden base for easy display and collection. The thick durable glass withstands prolonged heating and operation.
• Observe the entire operational process of the engine, understand the structure and principles, and witness the fascinating energy conversion. It is a peerless assistant to enhance hands-on skills, spark learning interest, and stimulate creativity.
• This captivating and impressive model, serving as a conversation starter on any desk, combines with the box, adding overall beauty and value. Ideal for a great Christmas or birthday gift for family and friends, children, teachers, students, and anyone passionate about technology.
