FANTASTIC SMART THING WITH EXTREMELY WELL MADE WHICH RUNS LIKE A DREAM----The stirling engine is produced with high quality material and elegant workcraft. this stirling engine adopts mirror surface stainless steel for the base, glass cylinder liner, zinc alloy flywheel. All the parts have done surface treatment to avoid rusting. Oil-free. OPERATION EASILY----Pour a cup of hot coffee, put the stirling on the cup, it run magically.

Its elegant gift package makes it spruce up and presentable. It has a wide range of application as, great gift for Kids' science project, Physical/mechanical learning, teacher’s Demo props on the class, birthday gift for friends, families, parents, kids, etc. Many of our customers come from school, colleague, etc. AMAZING CONVERSATION PIECES ON YOUR DESK----It's funny to see people's looks and reactions when they squeeze a little shot for this Stirling engine.

Great little Stirling engine. Running away from the warmth of my hand compared to the air conditioning.

This motor consisted of two parts, a wheel and all. He came and I went to the post office. I stopped in the parking lot and picked it up. It involves engaging the two connecting rods on the offset crank. You have to look at the steering wheel. One side is closer to the wheel than the other and if you look you can see that one line lines up with the displacer and the other line lines up with the power piston (the power piston is small. They snap. No). Tools are required. After snapping the crank

Great 200th Anniversary Gift! Not your ancestors, but the engine! Including assembly instructions.

This item is much better made than I expected. It's artistically attractive when it's on the shelf and intellectually attractive when it works. This is interesting to watch and motivated me to finally find out how this wonderful device works. I was surprised to learn how many Stirling engines are in use today and that new ways to save energy are still being developed. . And the fact that I somehow decided to find out, exactly 200 years after Scottish Minister Robert Stirling invented it…

exactly why the engine is running, in detail

This is an elegant engine, both in appearance and in operation. You can see all the parts moving. Of my five Stirling engines, it performs best at low temperatures. The Stirling engine is a heat engine, just like steam engines, petrol engines, hurricanes and the busy swinging drinking bird as a toy. The working piston is located in the large cylinder below. I call it the suppressor. It is driven by a crank on a flywheel. In a small cylinder, a working piston spins the flywheel twice per…

Pros
  • EASY TO USE ---- Pour in a cup of hot coffee, put a stirling on the cup, it works like magic. When it slows down, the temperature of the coffee is drinkable. Enjoy the physical display of the transmission mechanism and coffee. It can also work on an ice cube. Some people place the stirling in a cup of hot water and place small ice cubes on top of the stirling. This makes the temperature difference much bigger than normal and then runs even faster and crazier. Just enjoy the toy!
Cons
  • Communication with seller
