Product Description
It's really interesting and imaginative toy
This is an interesting model toys, this stirling engine mode uses the heat by alcohol lamp to generate electric. The electric will light the led light to emit different colors. It is a great opportunity for you to investigate how stirling engine works. It can inspire your curiosity and creativity.
EASY OPERATION & LONG LASTING
Fill the alcohol burner with your 95% alcohol (we recommend this fuel) and light it. Let the light burn the round ended cylinder for about 60-120 seconds, then give the wheel a gently push, it will run like a charm.
Packing List:
*Engine x1 ; *Lamp x1
*LED x1 ; *Spare tube x1
Product Advantages
EXTREMLY WELL-MADE
Heating cylinder for the custom-made thick glass material, long-term heating without pressure; It is mainly constructed by metal so it can run quietly and stably at speed around 1700 RPM! Our customers are satisfied with the fit and finish of this engine. Item done surface treatment to avoid rusting
ATTRACTIVE COLORFUL LED WITH MOTOR INSTALLED
The stirling engine equipped with a colorful LED. Because of the heat from high-grade alcohol, the engine will run madly and create the electricity. The power will go through the wire and drive the led light to emit different colors. It's really interesting and imaginative toy.
YOU GET EXTRA SPARE PARTS EXCEPT THE STIRING
Still worry about the cylinder glass broken during shipment or usage? It did come with spare glass tubes, one O-rings, check the gallery picture. You can replace it fast and easily if any broken.
AMAZING CONVERSATION PIECES ON YOUR DESK
Decorative and impressive, it's proven to be a conversation starter to impress your visitors. It’s a cool piece of art even just stands on your desk.

If you love Stirling engines, this is the one to get. Very impressed.
I am fascinated with Stirling engines and bought one of the low-temp coffee cup ones that I enjoyed for a little while before wanting more. I saw a couple of others but figured I'd get this one due to aesthetics and it was very well-rated.Build QualityI did not expect it to be as well-built as it is. It is very hefty and looks and feels expensive. The amount of compression felt as I turned the flywheel told me I was in for a treat in terms of power compared to the coffee cup one. It is fully assembled other than stringing the wick into the fuel chamber and mounting the LED. The wick can be a little fiddly but no issue once done as long as you don't pull on it. The LED (a spare is provided) is super simple to install...just put the ends through the provided terminals of the little generator, bend and you're done.Up and RunningI initially started with 70% isopropyl alcohol but that sucks so I got some 90% and got up and running. It takes about 30 seconds before you can get it to spinning on it's own but once it gets going, it is quite powerful for it's size and fuel source, The LED light is quite bright once it gets going and flashes and changes color to give the unit a bit of extra flare but I ended up removing it for something more useful and interesting to me (see Modifications). I've not let mine run much more than 5 minutes but I can usually run it three times before I need to add more alcohol so I would guess 15 minutes on a tank.ModificationsWhile the LED is okay, I wanted to measure the performance so I removed the LED and bought a small 2-wire voltmeter, cut the wires just short enough that they would support the weight of the voltmeter while remaining adjustable and soldered the ends to the generator terminals to give it rigidity and have a nice presentation. Display does not come on until 2.7-2.8v but it only takes a few seconds for it to get to that once it is running on its own. Typically my motor will generate 4.5-4.8v on a run but every now and then when the conditions are right I get over 5v with my current record being 5.35 volts. Love it.ConcernsIt has run flawlessly so far but I do fear that if it does break down, it may not be easy to repair as there are only a few spare parts included. Only other issue is that on many surfaces (glass and sealed stone seem best) it will start to move once it really gets to going and potentially could walk off the table if you walk away.This was a splurge of a purchase at the price I paid but I am loving it.

Reviewed in the United States on October 11, 2017
I am so impressed with its good qualities that I did not deduct a star for the failings of the instructions that came with it. I'll never understand why Chinese companies do not take the simple extra step to have someone who has English as a first language proof-read and clarify the almost universally poor English translations that ship with their products. The instructions that come with this are quite typical of that problem. For example: "Heating 20 seconds, and then began to gently turn the flywheel, (follow the starting direction shown in the figure) until the flywheel can since Dynamic operation so far." Yes, most will be able to figure out what that means, but why not state it in proper English? I'll note that the instructions cover both a Stirling engine and a steam engine. Paper is cheap, why not have separate instructions for each model? And the instructions for the Stirling engine include a figure of a different type of engine than this, leaving me wondering initially if I received the wrong instructions.
The model comes with several loose parts, some of which are spare parts, like and extra of each glass cylinder and generator drive belt, which is nice But there is no list of parts with a description, including those needed for operation. Again, it was easy enough to figure out, despite no instructions. But should either of the cylinders need replacing, there are no instructions for how to do this. There is an LED light that also came loose. This is a very cool, color-changing LED that demonstrates that the engine converts heat into usable electricity. Why it is not assembled to the model as delivered, nor even mentioned anywhere in the instructions is a mystery to me. It may also be a mystery to anyone who is not mechanically (or electrically) inclined that you have to spread the LED wires apart and bend the ends so they can fit into the holes in the terminals on the outside of the generator. The alcohol lamp had 3 parts, the glass bottle, wick, and lid. The lid is not threaded and just sits on top of the bottle, so be careful not to knock the bottle over while lit, or you'll have a little Molotov cocktail on your hands. When feeding the wick through the hole in the lid, some instruction as to how far the wick should extend would have been nice. I found that about 1/16" is sufficient, and more extension to give a larger flame did not seem to make the engine run any faster. So far, I've transported it back and forth to work a couple times and put a piece of plastic wrap over the wick and wound a rubber band around the bottle neck to seal it. A bottle with a seal-able lid would be a nice improvement. But I suppose the alcohol is cheap enough that you could just dump out any unused fuel if moving it. As is, all the alcohol in the bottle will evaporate rather quickly with the wick exposed to the air. (Here's a tip for filling the bottle from a can of alcohol without spilling more than goes in the bottle: dip a straw down into the can of alcohol, seal the top of the straw with a finger, then put the straw into the bottle and release your finger. Repeat until bottle is full.)
Despite the above nits, I think this is a very cool "toy", especially being a mechanical engineer with a deeper understanding of how it works, and am very happy I bought it. But I don't think you need to be an engineer to enjoy this. I thought the price was a little steep, but feel better about the price after seeing the high quality design, workmanship, and materials used. Oh, since I plan to keep it on display at work, I am concerned about dust collecting and possibly gumming up the linkages and power cylinder that is open to air, so I bought a mini-football helmet display case that it perfectly fits in...see the picture. The case is a "Ballqube Mini Football/Helmet Display Box".

Superb craftsmanship and flawless mechanical operation
Reviewed in the United States on October 11, 2017
This is a very impressive machine, with superb craftsmanship and flawless mechanical operation. It is a very attractive display item that I plan to keep on my desk at work, with a supply of fuel and a lighter handy to demonstrate to curious passers-by. My fellow engineer coworkers have also been very impressed with it. It runs surprisingly fast, and is not overly loud, but does make some noise.Reviewed in the United States on October 11, 2017
