Alot of fun and does not require batteries !This little toy is CRAZY FUN ! I'm an old guy and once I got it running I felt like a little kid at Christmas. It ran over 25 minutes before I took it off the hot water mug. It had slowed down quite a bit but even kept running for awhile just sitting on the table.Intend to put it on top of ice cubes and see how that works (per instruction sheet in box). I have always been fascinated with anything steam powered over a hundred years ago - trains, tractors, sawmills. It is mesmerizing to watch the mechanical parts moving in unison to produce a useable power force to benefit mankind. This "toy" is a great educational aid and I can not wait to show what is does to my grandsons (ages 3 and 7).Thanks Sunnytech for making such a high quality product at an affordable price. This experience has wetted my appetite to look at more"scientific toys" and my Amazon Wish List is going to get bigger for sure. 5Great 200th Anniversary Gift! Not your Ancectors', But the Engine! Assembly Hint Included.This item is made much more nicely than I expected. It's attractive artistically sitting on a shelf, and attractive intellectually when it's running. It's fascinating to watch, and stimulated me to finally learn just how this remarkable device works. I was surprised to learn how many current uses there are for Stirling engines now, and that new energy-saving uses are still being developed. . And that somehow I decided to learn about it exactly 200 years since Scottish minister Robert Stirling invented it, a strange coincidence for me. I am ordering a couple as gifts for my grandchildren to enjoy.One caution: This gadget does nothing more than sit on a cup of hot liquid and spin. It is not suitable for people of limited curiosity. But it is a great way to get a bright child away from shoot-'em-up games and think about how the principles of science they've (hopefully) been taught about come together to make all the things we depend on every all work.Unlike a few reviewers', my engine DID come with instructions! Just in case yours doesn't Here is my version, with a little hint about how the flywheel goes on:A. The flywheel has an axle with a little crank on each side of the wheel. They are spaced differently.B. Hold it so each crank is right above its connecting wire.C. Spread the support arms slightly and slip the flywheel ends into the little holes so it spins.D. Hook each wire over the crank pin above it and click its hook onto the pin.E. Sit the device atop a cup of hot coffee, wait 1-2 minutes, and spin the flywheel in one direction or the other to start it.F. When it stops, remove the engine.G. Drink the coffee.You may choose to vary steps E through G. 5There s something Zen about a Stirling EngineUpdate: I ve had this running 24/7 on the aforementioned warming plate I made for it for about 6 months now. There s no indication that it s going to quit. I would have thought that the arm would have sawed off the pin by now, but nope. As for the squeaking, contrary to the directions I put a small drop of light oil on the pin and that fixed it right up. Now for another PSA, if you get the urge to use an inverted can of compressed air to supercool the top plate, be careful not to get it on the glass cylinder because it *will* crack (I was able to fix mine). But, man, that engine will book when you spray it!________________Update: Just so you know, the DWCL-01 will not run if it s set on a magnetic surface because of the magnet in the displacer, unless that metallic surface happens to be extremely warm. That means if you buy or build a warming plate it has to be non magnetic. I built a warming plate out of some spare power resistors I had laying around (we all have a collection of spare power resistors, right?) using a pickle jar lid as the surface. The engine would not spin! Unless I picked it up then it would run like crazy but if I set it down it would stop again! Turns out the magnet in the displacer was sticking to the jar lid. So I got rid of the lid and set it down with a thin piece of cardboard between the engine and the resistors and it ran ok. Turns out the resistors are also slightly magnetic. Anyway, not a knock on the product, just a PSA. Your physics may vary. I got the DWCL-01 because some other people said it was a little better construction and had real bearings. When mine came today I opened it right off the UPS truck so the machine was pretty cold. I held it in my hand and it started right up. I heated up a couple mugs of water at work and it ran for just about an hour on each one. It s neither noisy nor silent; sometimes it makes kind of a sqeaking sound, but overall I find the repetitive sound soothing! This one will be my home engine but I might get another for my office just for the sound! Tonight I put it in the fridge then took it out, held it in my hand, and it ran like gangbusters. I have many experiments planned for it.As for the construction, it s smaller than expected but fit perfectly over the mug I had for it. The screws around the circumference actually held it in place nicely on the mug. The fit and finish is maybe not quite as nice as the photos but it s fine.While I had it in my office every engineer that came in wanted to talk about it. (One non-engineer came in and was like, What s that? and I said, A Stirling Engine, and she rolled her eyes and goes, Ok, whatever. ) So, in summary, it s cool and fun. Is it $40+ of fun? I don t know. Between the price and fit and finish I m torn between four and five stars. For the fun factor I m going to give it the benefit of the doubt and go with five. 5DWCL-01 Magnetic Striling Engine is Simpler, Sturdier, and Fully AssembledI bought the DWCL-01 because it is better made due to having bearings, one less piston rod, a metal arm instead of wires that may get bent, and comes fully assembled. The displacer disk is alternately held in place and let go by magnets instead of needing another piston rod. See https://www.youtube.com/watch?v=p42XrArULws for how it works. This model also spins in either direction compared to non-magnetic ones that spin in one direction for heat and the other way for cold on the bottom. I was initially disappointed when it didn't work when placed on ice instead of something hot. Seeing cold power something is more impressive and unexpected than hot. However, after a little thought I realized that since it needed the bottom to be warmer, I placed ice cubes on top of the base instead of on the bottom and that works just as well as heat on the bottom. 5Great 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. 5A Treasure for Grandfather, Grandson & the Whole FamilyI bought this and another Sunnytech engine for my 10-year-old grandson as a Xmas gift. On the gift card I was careful to note that we should unwrap the package together. The parts are delicate. He is careful and workmanlike in such things, but he's 10. The instructions, though not quite written in English, were easy enough to follow. The flywheel must be put in place and two small shafts connected. Of course, we first tried to fit the flywheel on backward and nothing fit right. A bit harder was attaching the shafts. Once my grandson understood what this was, his smaller fingers, practiced at Legos and Jenga, were better than grandfather-fingers.Once assembled, we looked for something hot to set it on, and wound up filling a coffee cup with hot tap water. We may not have waited long enough, and the question remains: Will hot tap water power it?" We probably moved on to microwave water too quickly. One minute on high - my standard for old coffee - was our next effort. At first it wouldn't go. Yes, it takes a while for the heat to transfer to the cylinder where the work is done, but we hadn't quite figured out how it worked yet - didn't quite understand where the working cylinder was. It didn't take long before our attempts at making it spin almost worked and then worked. OK. That was the first big moment.The machine is a clockwork and makes a wonderful whirring and clicking as it runs, and the beauty of the thing just begs one to ask, "How?" Together we read a bit and figured out where the power was coming from. I think there's still more for us to talk about there about the specific heat transfer occurring.Then everyone in the house came, and wondered at the this miniature, spinning motor apparently running on a cup of coffee. The instructions had warned us against lubricating with oil which will clog the machine with dust, but said lubricate with graphite when needed. It wasn't needed, but grandson asked dad if he had graphite for lubricating, and he did. I suspect there are a few lessons concealed there.We read the instructions again and saw that the engine could be powered by cold as well as heat, and filled our cup with ice cubes and waited for the temperature transfer to reach the cylinder. It didn't work soon or run as quickly with ice as with hot water, but we have not yet thought about measuring the temperature differential, and I have to say I'm just getting my own head around what is happening. Is it enough to measure the temperature on the two metal plates, the one above and the one below in order to measure the differential that is powering the cylinder? Is this at least a reasonable approximation? How can we measure the speed? What's happening when it finally slows down and stops? Why? Is the coffee cold - the ice melted? It doesn't take long to generate honest questions.This is a "toy" we will come back to shortly for further thought and perhaps experimentation. It was a clear winner. Dad is already thinking about how to give the two engines a clean display place that recognizes them as beautiful, precision engines. 5Excellent example of a Stirling EngineThe quality of the parts is excellent. The design is simple and offers complete visibility of the working engine when running.The assembly time is short and the tasks are simply to put the flywheel in position between its bearings and engage the two connecting rods. I would advise using a small needle nose pliers for the connecting rods - you can do it with just your fingers but using needle nose pliers makes it trivial to do.Once together, just put it over a mug of steaming water/tea/coffee/etc. and lightly turn the flywheel after about 30 seconds. The momentum of the flywheel starts the cycle and you can observe how a Stirling Engine works. Great for showing interested kids/teenagers how something in the real, physical world actually converts the waste convective energy from a coffee cup into useful mechanical motion. 5Beautiful 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. 5Amazing little engineI ordered this Stirling engine for my father, who is a thermodynamics university teacher as a gift for Christmas. But since Christmas is a few months away i had the chance to play with this little engine for a while and i must say i can't be more happy with my decision both to buy it and to play with it :)I will upload 2 videos, one with the engine starting up and one with a 360 degrees view of it running.Basically you can run this engine up to 20 minutes with a cup of warm water (the engine must be cool). The bigger the temperature difference between the top and bottom plates the higher RPM you will get. This works best with a hot cup of water underneath and an ice cube in a plastic bag on the top (there is plenty of room for one ice cube on top).I was a bit worried on a second run, the engine wouldn't start because it got warm (so bottom plate/top plate temperatures stabilized) but after i let it cool down it ran again just beautifully.I consider replacing the screws holding the two plates on main cylinder with plastic M2 screws so the heat transfer would be greatly diminished so the engine would run even longer.Check out the videos and images i uploaded, this little engine is a great investment for both fun and educational value. 5Great build quality... runs flawlessly. I'm a big fan of functional models, so I was happy to spot this low cost Stirling Engine on Amazon. I've seen similar models for more than three times the price, but I thought I would take a chance on this one. I'm glad I did. This model has great build quality and it runs flawlessly as expected.I've tested it with under both hot and cold conditions and it runs beautifully both ways.First, I simply put it on top of a cup of hot water. The base is pretty wide, so it's got great surface area, and it fits nicely on top of most coffee mugs.Next, I just put it in my hand, with a couple of small ice cubes on top. The difference between the heat of my hand and the ice cubes was all it took to keep the engine running a long time.In this video, you'll see it in action, and for the record, I didn't check to see how long it would run on the cup of hot water... but I stopped it after about 20 minutes and it was still going strong. 5
