Alright, thanks for the reply, Paulanddiw.
I'm doing this cooler for demonstration purposes only, so it need not reach cryogenic temperatures. I'd be VERY happy if the cooler could make ice, which would be more than enough for my demonstration. I could show that a little flame from a low...
Thanks.
The one thing that I think is good for this kind of stirling-stirling cooler is that the hotter the temperature to which you're subjecting the first stirling, the colder the second stirling gets, so this makes it valuable in cooling processes. Like I said in a previous post, say if I...
Okay, thanks very much. I will probably gear the heat driven stirling to drive the second smaller heat pump. I'll create a long and skinny displacer type stirling for it, or are alpha stirlings better?
For my cooler, I'm not so ambitious as to make it liquefy air, although I must admit, now...
Okay, thanks. I've basically ditched the flashlight idea because LTDs just barely overcome friction so I'm 99% sure they'll be unable to drive ANY external load.
I'm fully concentrating on the stirlig-stirling cooler for my science fair. One thing good about it is that the hotter something...
Hi. I know of the commercially available "battery-less" flashlights that use either squeezing or shaking mechanisms to generate electricity. I was wondering, however, whether I can create one that uses the difference of temperature between the hand and the room temperature. I propose to use a...
