Low Temperature Stainless Steel Stirling Engine

This low temperature stirling engine runs on a hot cup of water and could be a great conversation starter at work, as well as a unique gift for families, friends, or for class demonstrations. It is almost ready to run after installation - simply place it on a cup of hot water or ice water, wait a couple of seconds, gently flip the wheel, and it will run itself.

The engine's speed depends entirely upon the temperature difference between the hot side and the cold side. When using a cup of hot beverage, the engine not only transfers the beverage's heat to the surrounding air, but also experiences air currents constantly crossing the top (cold) plate. The differing temperatures will cause the engine to slow or speed according to the net difference between the two plates.

For some extra fun, you could obtain a USB-powered cup warmer and place the engine on that. After the warmer finally made it to full temperature, the engine will chug along like a champ. The size of the engine is 102 X 102 X 125mm, and it is made of steel and glass. It weighs 236g, and has a speed of up to 180-250 RPM with a start temperature difference of 20 ℃.

This engine is durable, well-made, stylish, and adjustable, with fantastic craftsmanship in metal alloy. However, if it is a little noisy, only use a little graphite dry lube or a pencil to quiet it down, and do not use oil to lubricate, as this will mix with dust in the air and create oil-dirt, eventually making the friction even bigger and causing the stirling engine to run less smoothly.

In conclusion, this low temperature stirling engine is a unique and interesting item that makes a great gift and conversation piece.
