This low temperature stirling engine,runs on a hot cup of water, could be a great conversation starter at work and unique gift to families or friends or for class demonstrations.It is almost ready to run: after the installation, put it on a cup of hot water or Ice water, wait a couple of seconds, gently flip the wheel,then it will run itself.
Basically you can run this engine up to 20 minutes with a cup of warm water (the engine must be cool). The bigger the temperature difference between the top and bottom plates the higher RPM you will get. This works best with a hot cup of water underneath and an ice cube in a plastic bag on the top (there is plenty of room for one ice cube on top).
Durable, well made, sytlish, and adjustable.Very fantastic craftsmanship, made with Metal Alloy
If there is a little noisy, ONLY use a little graphite dry lube or a pencil quieted it down nicely. Do not use oil to lubricate,which will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger.The stirling engine can't run smoothy.

The engine's speed depends entirely upon the temperature difference between the hot side and the cold side. In the case of using a cup of hot beverage, not only is the engine transferring the beverage's heat to the surrounding air, there are 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 engine on that. After the warmer finally made it to full temperature, the engine will chug along like a champ.

Well made, quality hardware. When I first run it there was a squeaky sound. I tried rubbing pencil lead (graphite) as suggested on the internet. Well, did not eliminate the squeaky noise so I use light oil. Now it is quite and seems to run faster.
DO NOT LEAVE OVER AN OPEN FLAME such as a zippo. Melted the displacer in mine last night. Besides that though this is a very fun toy and fairly entertaining. It needs a fair temperature difference such as placing it on top of a cup of coffee or tea but it runs great. A bit squeeky and a little louder than I expected, but the novelty of having a fun piece like this is worth it.
Even though I ruined mine I'd definitely purchase again.
it was a fun little toy for about 4 hours, until the diaphragm sheered off and the glass cylinder shot right out and broke when it hit the floor. another problem is the main cylinder is made out of plastic and will start cracking if you expose it to too much heat. like a small burner set to simmer or a candle, and if you use a cup of hot water, the water cannot be boiling or the cylinder will break.
