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 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.

Description

Description:
Moteur Stirling est un moteur à combustion externe qui a un parfait potentiel pour convertir la nouvelle énergie en électricité.
La température d'un verre d'eau chaude suffit à faire fonctionner le moteur rapidement et la coordination des différentes parties peut être observée de près. Son excellente exécution fait également le modèle un bon cadeau d'anniversaire pour les petits garçons.

Caractéristiques Principales:
• Alimenté par l'Eau Chaude. Un verre d'eau, dont la température est supérieure de 30 degrés à la température de l'air, peut constituer une alimentation parfaite pour ce moteur. L'ensemble de l'appareil commence à fonctionner après avoir poussé le volant dans le sens des aiguilles d'une montre / dans le sens inverse des aiguilles d'une montre.
Bon Outil pour l'Etude de la Physique. Le modèle peut grandement susciter l'intérêt des enfants pour la conversion de différents types d'énergie. Cela peut aussi les amener à en apprendre davantage sur l'application de la nouvelle énergie de nos jours.
Facile à Assembler. Aucun outil supplémentaire n'est requis. Vous avez juste besoin d'appuyer sur les petits crochets sur l'arbre, et mettre l'arbre entre les deux jambes.
• Le petit cylindre se compose d'un piston en verre et d'un cadre en acrylique, la résistance entre eux est donc très faible mais l'étanchéité à l'air est impressionnante. De plus, il est peu probable que la base en acier inoxydable lisse rouille.

Remarque
• La base du cylindre ne peut pas être brûlée sur le feu

I'm a big fan of functional models, so I was happy to spot this low cost Stirling Engine on GearBest. 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.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.

Comes partially disassembled, but very easy to put together. Mesmerizing! Heated a coffee mug of water in the microwave, put the engine over the cup and gave the fly-wheel a turn. The engine started up and over a few seconds increased its speed to maximum. It kept the grandkids (and grownups in the room) watching and periodically peeking in to see when it would stop. 35 minutes later it was still going, albeit much slower. With some extra instrumentation that the user would need to obtain and configure to measure the volume and temperature of the water, the temperature of the plates, and the mass and speed of rotation of the fly-wheel, the device could be used for some high-school level physics experiments. I have not done this, but seeing the engine work as well as it does, it would appear to be the next step beyond simply watching the device.

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 usable 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 for making such a high-quality product at an affordable price. This experience has wetted my appetite to look at more"scientific toys".

Extremely satisfied with my purchase. This is a well-made item and works just as I expected. Minor assembly required, and that's due to the design. I bought this to serve as an attention getter for a set of poster presentations at a technology company. It was very effective. Its low speed and graceful lines were instant attention getters.The little engine is well made, and worked right out of the box. I have used both hot water from the tap, and ice-water mix to run it. As expected, a cold source makes it run in the opposite direction than a hot source.

I offered this to my father who really likes engine and their internal mechanism. The fun part is to make the engine working: one ice cube on top, a lighted candle at the bottom and a bit of momentum. That's cool to watch.Otherwise, shipping was perfect, and the product arrived in good shape. The manufacturing seems robust enough for what it is.
