Stirling engines are unique heat engines because of their theoretical efficiency is almost equal to the theoretical maximum efficiency,
Called the Carnot cycle efficiency. The Stirling engine is heated by gas expansion, cold contraction generate power.
Description:
Name:Stirling Engine Hot Air Model
Material:metal,glass
Color:gold
Size:165x87x95mm
Features:
-This is an external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air (or helium or hyd rogen) as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation and strong power.
-As the external combustion engine to avoid the traditional internal combustion engine of the explosion to do work, in order to achieve a high efficiency, low noise, low pollution and low operating costs.
-The biggest advantage of the external combustion engine output and efficiency from the influence of altitude, very suitable for high altitude areas.
- Aerodynamics are rich in knowledge of physics, single cylinder combustion engine. Engine principle is intuitive, educational toys, teaching experimental equipment can effectively cultivate children's interest in learning can also be used for classroom teaching, more intuitive and easy to understand.
Instructions:
-The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.
-The packing bag of alcohol lamp cotton wear into the metal cap lamp.
-Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.
-Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.
-Led lights can be directly into the generator output interface, if not inserted, the exchange can be positive and negative, led a long foot for the cathode.
Note:
-There will be the operation of steam,when the steam too much time, the engine will stop working,
inside and outside the needle often set aside to reduce friction
-Do not rotate the nut too tightly, otherwise the glass is broken, if the piston is cracked,
can be bonded with glue.
-The alcohol lamp wick do not touch the glass, do not get too tight ring
-Pulling the piston connecting rod can not force the front end, because the front
end is easy to break
Package include:
1 x Stirling Engine
1 x Alcohol Burner

I've now purchased about 3 of OLEVS watches.. The fit great.. Band is so easy to ajust. I'm super careful. So I took great care and time on the first OLEVS watch. So it took me about 15 mins. Now about 6 from start to finish.. Don't hesitate due to fitting the band. You get to custom fit it to you. And it's easy...real easy. Best of all. You get to keep the adjusting tool they provide...

Gorgeous watch!
Color: Silver, Color: Silver
This is such a beautiful timepiece! After a couple weeks I have yet to have to adjust the time. It keeps time as well as my other olevs that are quartz movement. The price is great, comfortable for all day wear, perfect size for me and the weight definitely feels on par with much more expensive automatic timepieces. This won't be the last olevs I purchase

Beautiful Watch, but . . .
Color: 6617:Blue Dial and Gold Silver Strap
I’m updating this review and lowering to one star. Would be zero if possible.
Another 2 weeks of owning this junk watch. I’m now having to wind it daily and reset the time. The only reliable feature is that it’s going to stop in the middle of each night. Piece of junk. Don’t buy.
This is a beautiful watch but not very reliable timepiece. This is a self winding watch which requires you to wear it 24/7 in order to keep working. i wanted a nice watch which looked good, kept good time, was affordable and a bit nicer.
I work a standard M-F, 8-5:00 workweek. I wear my watch daily for work and on RARE occasions after work or weekends if going out. My watch typically sits on the bedroom dresser after work hours and weekends. I've had this watch about 3 weeks now and have had to wind it and reset the watch three times during the time I've had it. If you are not wearing it for more than a day the watch runs down and and comes to a complete stop. You then need to manually wind and reset.
This was a concern after reading other reviews. I tried to find the same watch with a quartz movement and battery for this very reason. But this particular watch only comes in a mechanical self winding version. They have ONE other model with a similar look that has a quartz movement with battery. That watch is made in China; this one is made in the USA. This is another factor that convinced me try the self winding mechanical version. Big mistake, I should have looked at other brands and manufacturers. It turns out this was a regrettable impulse buy based on looks but not practical. It is not a reliable timepiece. Lets face it a watch's function is to reliably tell the correct time; if you're not willing to manually wind it and reset the time and dates every Monday morning this is not a practical timepiece. I would NOT buy this again for this reason.
