DjuiinoStar Mini Hot Air Stirling Engine: A High Performance Pocket-Sized Working Model

<p>Driven by the little lamp, this engine will rotate at speed around 1700-2000 RPM. It's assembled and will run within 5 minutes after opening the package provided you have a bottle of alcohol by your side.</p> <p>It is a MINI version which can be put into your pocket. A little bit smaller than a 330ml Coca-Cola can. But do not be confused by its size, its quality and performance are very good! We've done special treatment to the machine to avoid rusting and fading; use heat treated high grade spring steel stand to ensure its stability; employ thickened quartz glass cylinder and bearing steel rod to strengthen its robustness; specially designed Lever Mechanism and Crank-rocker Mechanism makes it more "mechanical". It will definitely be a great gift to those with mechanical brains. A great desktop toy for everyone.</p> <p>It's also a perfect teaching tool demonstrating the process of energy exchange: the hot air in the sealed cylinder enables power piston to move continuously, and flywheel will spin at the same time; periodical air expansion and contraction makes heat energy converted to mechanical energy... Kids will be excited and curious about why. This will enlighten them to explore the world.</p> <p><b>Features:</b><br> Brand: DjuiinoStar<br> Model: DHA-BS-301<br> Status: Assembled<br> Speed: 1700-2000 RPM<br> Overall size: 3.98x1.81x2.36in(L/W/H)<br> Net Weight: 3.95oz<br></p> <p> <b>Packing List:</b><br>*Engine x1<br>*Lamp x1<br>*Pipette x1<br>*Spare tubes x2<br>*User manual x1<br></p>
