Sunnytech Low Temperature Stirling Engine Motor Steam Heat Education Model Toy Kit For mechanical skills (LT001)
Key features
- •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, precision bearing, bearing steel shafts, 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. When it slows down, the coffee temperature is suitable for drink. Enjoy physical powertrain mechanism display and coffee. It also can work on top of ice cube. Some guys put the stirling on cup of hot water and put small ice cubes on the stirling upper plate. This makes the temperature difference much bigger than normal, then it runs even more fast and crazy. Just enjoy the toy!
- •LONG LASTING----It can run for 24+ hours continuous without any broken if there are continuous power supplies. One customer put the stirling on USB hot plate (excluded in the package) and the stirling runs on his desk for weeks. Don't burn the stirling base or put it in the stove, the stirling plastic parts will damage.
- •PRIORITY GIFT OPTION FOR MANY APPLICATIONS----It is an amazing and fantastic product at this price. 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. Put it on the cup which full with hot waters, give the flywheel a gently push, and get the flywheel going, and then it works like charm. All of your guests want to know what happened, ice-breaking success. What a marvelous toy!

Fun and educational. Noisy though - gotta lube it up!
J. Jones✓ Verified Purchase•October 2, 2017
Works and is fun, though I ordered white and got silver. Not blaming the product, that's the seller's fault.
Noisy though - gotta use some dry graphite on the pushrods and crank connectors to lube it up. The pins holding the flywheel in place are actually silent and efficient - it's mostly the displacer pushrod that makes noise. After I lube it I hope it gets more efficient. Struggling to get started at low power levels.

Great little Stirling engine. Ran off the heat of my hand vs. air conditioned air.

This engine came in two parts, the wheel and all the rest of it. It arrived and I had driven to the post office. I stopped in the parking lot and put it together. This is a matter of hooking two connecting rods over the offset crank. You have to look at the wheel. One side is closer to the wheel than the other and of you look, you will see that one lines up with the displacer and the other lines up with the power piston (the power piston is the small one.
They kind of snap on. No tools are needed.
Once I had the connecting rod snapped on, I put the engine in my hand, and I put it in front of a vent so that the AC blew on the top and my hand was underneath, there might have been a 20F difference in temperature. After a minute, I gave it a spin and it started. It ran slowly, about 60 RPM. But it ran. On the difference in temperature between my hand and the output from an AC vent.
I took it home, it ran most of the way. I have a sous vide that maintains 160F and has a plastic top to slow evaporation. I put it on top of the heated container. and after a short time I spun the engine and it started. I decided I wanted more speed, so I put a zip lock bag of crushed ice, sealed, on top. The speed probably hit 300 RPM.
The engine has been running for more than an hour. It runs about 70 RPM (just a guess, slightly faster than I would count seconds).
The fit and finish is better than I expected from looking at the picture. The engine is useless other than as a physics demonstration. I have wanted one of these for some time, but I never wanted to spend way more money than this costs for something that is just a toy..but this is much cheaper. It works. It is shiny.

Beautiful Toy, a great way to learn about Enthalpy and thermodynamics.

This Stirling engine showed in perfect shape, with a few simple steps to assemble. Heated a wide mouth cup to around 80 degrees C, and a nudge, the engine started up and chugged along merrily. Later put ice in a bowl, and waited, the chugging was just a little slower than the hot water, but still magical.
If you do not know Thermodynamics, this device, even more than the dunking bird shows a very simple thermodynamic cycle: Stirling Cycle.
Now you will want to learn more! Why don't we use these in our cars, our machines? Well dig in, because you will find out that the overall system doesn't really allow for inexpensive systems with high torque. Steam turbines, ICE and Diesel engines have high power with high torque output.
However, if you want to explore the concepts of enthalpy, this is the system for you!
I bought this when I realized that to build from parts was going to cost me around $40, and with the price drop after Christmas, this is a sweet deal at the price I paid for it.

Great engine, Simple to optimize.

This engine is a bargain compared to other engines here. I was able to make adjustments to the engine to make it run faster and longer. I am not really a crafty/handy guy, but was able to figure out what needed to be tweaked. It was relatively simple. The engine has been running consistently for the past 20 minutes, and shows no signs of slowing down. There were squeaks that were hard to locate at first, but I realized they were coming from the hooks that attached to the flywheel axle. I 180'd each hook and the squeaking went away. The arms that hold the flywheel up play a big role in the performance of the engine as well. I carefully bent them to a better position to allow the least amount of resistance, and greatest amount of balance for the flywheel. I also used other reviewer's advice to use graphite powder for a lubricant and it turned out to be very helpful.
Wish it was assembled more solidly

It came well packaged and on time for my son's birthday.
We assembled it according to the included instructions and it failed to work. The instructions didn't include any useful troubleshooting tips and while attempting to start the flywheel spinning, the displacer piston fell off the shaft. We disassembled it for closer inspection and found that the piston is just a foam rubber disc that is pressed on a thin piano wire shaft. It just wasn't built to hold together. We used some super glue to reaffix it to the shaft and looked on the internet for troubleshooting advice. The main thing that popped up was increasing the temperature differential by placing an ice cube on the top heat sink next to the flywheel. It worked for about an hour when the displacer piston fell off the shaft again. This seems to be a rather common failure for this product. It was a fun couple of hours with the kids but, for the price, I expected it to at least last for the weekend.
