DjuiinoStar Low Temperature Stirling Engine Rotate 30 Minutes on A Mug of Hot Coffee

CINDERELLA IN STIRLING ENGINE WORLDunlike most of the Stirling engines it's mainly constructed by PC resin & ABS plastics (except some essential parts) but it works AMAZINGLY. In our Fatigue Test it rotated continuously for 5 days with no wear-out! It's actually of fine workmanship lightweight and portable. A fantastic desktop/physics/mechanics toy for everybody especially for teens. A GREAT STIRLING ENGINEcompared with traditional engines this one runs smoother and is more stable: use self-lubricated graphite power piston(less friction & unbreakable); stainless steel string as connecting rod between flywheel and piston(less friction); two little magnets on the power piston and displacer interact with each other as connecting rod to eliminate mechanical friction; integrally-formed base strengthens the stability and air tightness greatly while providing clear view. Manufactured by DjuiinoStar. A BIG HIT FOR EVERYONEwell I mean those dont see a Stirling engine before… When having friends at home it's absolutely gonna be an eye catcher; kids will be as excited as Wright brothers saw their first toy helicopter hovering in the sky they will wonder about whats happening and why. It's also a great entertainment for people in the office definitely an innovative desk piece totally amazing your work friends walking by. WIDE APPLICATIONS/GREAT GIFTthis engine will be a remarkable gift for anyone interested in science. It's a great conversation piece that could be used as teaching tool on demonstrating physics knowledge. Enable kids to think about basic principles of the universe. It's a toy making one feel relax and it's affordable! Bonus: operating temperature differential of this engine is around 63-72 F so when it slows down on a hot coffee mug you know your coffee is cool enough to drink:-) Have fun! A LITTLE ENGINE RUNNING ITSELF LIKE JERRY MOUSEthis model is powered by temperature difference between top and bottom panel of the clear base. Here is how it works: put the engine atop a mug of hot water and give the flywheel a little push it will start to rotate by itself and the speed will reach maximum seconds later; then speed will die down slowly. If using boiled water as heat source the whole process will last for 30-40 minutes and the rotating speed could reach 600-800 RPM.
