Low Temperature Difference Black Magnetic Stirling Engine Toy Gift Decor Collection

Features:

• ★EASY TO PLAY: The temperature difference between the top and bottom panels powers this engine. Simply remove it from the packaging, set it above a mug of hot water, wait a few seconds, then gently push the flywheel in one direction to start it. It will continue to rotate for days if there is a strong source of temperature, just like Forrest Gump! Compared to most engines on the market, the operating temperature differential between the two panels is less than 15-20°C/27-34°F.
  ★STIRLING ENGINE OF HIGH PERFORMANCE: This engine is more steady and runs smoother than conventional ones: Use a self-lubricating graphite power piston (less friction and unbreakable), stainless steel string as the connecting rod between the flywheel crank and the piston (less friction), and two tiny magnets that interact with each other as the connecting rod on the power piston and displacer to effectively eliminate mechanical friction while elegantly simplifying the structure.
  ★A FANCY DESKTOP TOY:If you set this stirling engine on a mug of hot coffee, it will operate quietly and quickly. In order to make it seem nicer and function better, we also use better materials with unique surface treatments: The polished standing rod made of aluminium alloy has a smoother and brighter surface and is stable enough to stand on the base. The clear acrylic flywheel gives the entire engine a more attractive appearance.
  ★A BIG HIT FOR EVERYONE: Kids will be as intrigued as the Wright brothers were when they first saw their miniature helicopter hanging in the sky when having guests around; it will undoubtedly draw attention. It's also a fantastic source of office fun, and as your coworkers pass by, it's unquestionably a creative desk accessory. Everyone will love receiving this attractive engine with a brushed aluminium base and a finely polished standing rod.
  ★WIDE APPLICATIONS/GREAT GIFT:It will make an incredible present for any scientific enthusiast, serve as a fascinating topic of conversation, and encourage children to consider the fundamental laws of the universe. You should try this one, especially if you previously owned a Stirling engine, and I suspect you won't be sorry.

The temperature differential between the top and bottom panels powers this Stirling engine. Placing it on top of ice or in a mug of hot water is the quickest and easiest way to create a temperature disparity. The differential has a significant impact on rotational speed; the higher it is, the faster. According to our test, it can rotate on a mug of boiling water at a rate of between 600 and 1000 RPM.

The Operating Temperature Differential of this model is around 27-34°F, much lower than most of the engines on the market. It can continuously rotate for 20-25 minutes on a cup of 140°F water, safer for kids. Please note when you use 140°F water (its steam actually) within a 250ml tea cup as heat source, the temperature of bottom panel is about 122°F.

Our technical team has implemented several successful measures to enhance its performance, including the use of magnets to interact between the power piston and the displacer in order to effectively reduce mechanical friction while maintaining the stability and simplicity of the entire structure; a self-lubricating graphite power piston in order to reduce friction and increase robustness; and a stainless steel string acting as a connecting rod between the crank on the flywheel and the power piston in order to reduce friction further (less contact area). Everyone will enjoy receiving this eye-catching desktop toy and gift.
