Well, I thought this was a good idea...I maen, if used as a cooling system, then the hotter the object to be cooled, the colder the cooler becomes...Isn't that an ideal property for a cooling system to have?

<t>I'm building it as a science fair project. I'm not seeking any money or patents from it of course, just as an "accomplishment". =)<br/> <br/> I've done a fairly thorough search online about building Stirling engines, and I'll start with fairly easy ones that can be built without lathes and millin...

<t>Alright. Thanks. I am aware of the fact that there are many commercially available Stirling cycle coolers and even cryocoolers, such as the ones produced by the company that I think is called Global Cooling. However, I've searched around online and I haven't found a stirling-stirling cooler using...

<t>ld I attach the cooling area (a metallic box) outside the I am trying<br/> to build a Stirling-Stirling refrigerator. I propose to drive the<br/> first Stirling using the heat from concentrated sunlight, which powers<br/> a second Stirling to achieve cooling. I hope to get this machine to be<br/>...

<t>Hi. I know of the commercially available "battery-less" flashlights<br/> that use either squeezing or shaking mechanisms to generate<br/> electricity. I was wondering, however, whether I can create one that<br/> uses the difference of temperature between the hand and the room<br/> temperature. I ...
