    Took me a while to assemble for the only reason that the little nob that pushes the piston was bent out of shape and the wheel suspenders where bent as well wi h made the spin unsmooth but after a little tinkering I'm happy to report it does work and it definitely a bang for your buck So Far So Good

    Dieser Stirlingmotor ist ein kleines, hübsches Lernspielzeug und ist gut verarbeitet. Allerdings ist das Schwungrad verdreht, so dass es zu Reibung mit dem Glaszylinder kommt. Wer Interesse an dieser Art von Modellen hat, sollte dieses Produkt nicht missen. Ich habe darüber bei Youtube 2 Videos gemacht: https://youtu.be/R9XKzKJ7Fr4 und https://youtu.be/B5lzZpJxwfs --------------------------------------------------------------------------------------- This Stirling engine is a small, pretty educational

    Well, this is one of my standard mugs that I normally use for coffee. But now, when the coffee is ready, I prefer to wait a bit until it gets less hot and to see this nice Stirling engine turn for about a quarter of an hour. When you put the engine on the mug, you need to wait about half a minute and then you have to turn the wheel by hand a bit to start the engine. From then on, it'll work on it's own until the heat from the mug has lowered too much to make the engine turn the wheel. I had this

    Maquina que funciona con la diferencia de temperatura entre la parte inferior de la superior Muy bien embalada, incluye un regalo. Facil de montar y hace el ruido que tiene que hacer una maquina de estas características. Un día de estos le pondré grafito en los ejes Operated machine the temperature difference between the bottom of the upper Very well packaged, it includes a gift. Easy to assemble and makes noise to do a machine of this kind. One of these days I will make him graphite shafts

    very cool experiment. runs great and much faster than I anticipated. in my experience, so far, you will need to give it a slight push to start it but if it has conducted enough heat on the bottom, then it will run very fast and you can then remove it from the heat source. I would recommend using hot water, as water can’t melt the plastic piece that is used to house part of the piston. ordering several more.

    Amazing and well-made warm-air Stirling engine. Good quality manufacturing of all the delicate parts on this engine. Makes a slight squeak when running, but a bit of graphite, or a lead pencil rubbed on the crank journal and the noise went away, to create a smooth, quiet-as-a-mouse wonderful engine. Sitting it on a cup of coffee it ran for about 45 minutes. I must admit that (a) I made the coffee as hot as possible and (b) the coffee was in a well-insulated mug. When placed on top of a regular

    Uwielbiam zabawki oparte na prawach fizyki więc musiałem to kupić. Model ładnie wykonany i rewelacyjnie się prezentuje. Postawiłem go na obudowie od MiniPC i gdy się nagrzał wystarczyło lekko popchnąć i zaczął działać. Polecam

    It is difficult to assemle it such that it stays together. Works fine on a hot cup of water. It is nice to look at. It makes some noice as it spins, but that is OK.

    Looks good runs good, fascinating to watch. I purchased a coffee cup warmer to provide a steady source of heat and a display jar to keep the dust off.
