DjuiinoStar Most Classical Low Temperature Differential Stirling Engine DLTD-303
This engine is driven by the temperature differential between the top and bottom plates. To create enough temperature differential, simply put it on a cup of hot water. The rotation speed depends on the temperature differential: the higher, the faster.
When in good condition, that is, after working for a while and being lubricated, it can reach a speed around 220-250 RPM driven by boiling water. Please refer to the video attached to learn how to operate and lubricate.
It can run for a long time providing there are continuous heat supply.
A Real Working Model
Yes, it is a working model that runs! Its flywheel will keep rotating if there are enough temperature differential between top and bottom plates.
Unique Coffee Timer
Simply prepare a mug of hot coffee, put this little engine onto the mug for a while, then gently turn the flywheel, it will run magically. When it slows down, your coffee is suitable for drinking.
Ideal Gift Option
Our engines are packed carefully in nicely printed boxes. It’s a good idea to send it as a gift to your families and friends; it’s a very good gift for engineers, tech nerds, or anyone who has a child in his/her heart.
