  Still no takers on chatting about this idea?
  Here's a link for some info on the operation of thermoacoustic heat pumps. Ben & Jerry's ice cream is planning on using this technology in the near future for their refrigeration needs.

  Re: acoustic heat pump
  
  There is a lot of info on the web about such items, but much of it is research and filled with math that is beyond me. Penn State has a nice demo kit for experiementors for $14 + $10 shipping. For more about these demo kits, check out #-Link-Snipped-# (magazine for the Society for Amateur Scientists) and #-Link-Snipped-# magazine (the magazine of Sigma Xi). There is a nice article (simple) here:

  I'm just getting into this area and working on a series of articles on the subject for makezine (makezine.com) aimed at someone getting started in this area as a hobbyist.
  
  What are you trying to make?

  Gnomic,
  
  Thanks for the information! I as well have been keeping up as this technology develops. I'm not currently making anything specific with this device, I was interested in sparking conversation about this technology, its possible applications/impact as well as the theory behind its function. I was planning on making a home built unit in the coming months as a tech demonstration. I'll also check out that demo kit as well.

  What amazes me is that there is tons of research, but lots of room for non-scientists (engineers, hobbyists) to experiment and still learn things. One of the things I did when narrowing down the field of projects I wanted to focus on was apply TRIZ to the variables. Thermoacoustics (TA) has a lot of variations that haven't been fully tried. A lot of the focus is on higher cooling efficiencies, but my focus is on lower power inputs and scaling up (i.e. brute force) the effect for a greener solution. If people can build and sell wine coolers that use grossly inefficient pelter chips, then I think there is a market for low-tech TA coolers.

  This topic is very interesting.
  I chose this topic as my seminar topic.

  Vishal,
  
  Please share with us all your seminar ideas when you are able. Hope it goes well!

  I think you may try to see this thing, #-Link-Snipped-# accustic heat pump. A laboratory exercise is replaced with an experiment developed by Christopher French for his Senior Seminar project.

  Thanks for sharing this article thermodix. Sure is a great topic for those studying & in need of a "green" project involving new technology, fairly simple too.
