Does anyone know where I can get the plans to build one?

Sci Gal, Ck out Codys link, It does work just like the RV Propane, or Electrical heated element, 12v and 110 v in the Made for rv fridge. Science …hum, maybe you should consider another field…

I bet this could somehow be combined with the IceBear air conditioning unit so that you could cool your house more efficiently.

Hmmmm….evaporator and pressure difference? Um, that’s how normal ACs work, ScienceGal. Cool a hot liquid at high pressure, let it evaporate at lower temperate, and the temp drops. I’m not sure the description is great, but the university’s site corroborates the article.

Science gal: prove your claim.
I can’t find a mythbuster’s episode that matches your description:
http://en.wikipedia.org/wiki/List_of_MythBusters_episodes

and the team site is here:
http://www.engr.sjsu.edu/jrhee/solar/people.htm
ON the SJSU website.

You should be here:

ScienceGal (Susan Maples??) or you just lost ALL credibility. You can get to this site EASILY from the SJSU home page.

Yeah, its as ridiculous as those mythical refrigerators that are powered by propane.
How can something use heat to make things cold?

Seems counterintuitive, but its thats science for you.

B.S. That is all. Move along, nothing to see here.

This is based on an “Urban Myth”, that you can use high heat to set-up a huge ‘thermal difference’ and literally “suck” the heat from one object to another, thus cooling one of them drastically and rapidly. This has been disproved on a number of occasions by Universities, Think Tanks, Research Labs, hell, even the Discovery Channel show “Mythbusters” tackled the question. ALL come up with the same answer — B.S.

The above referenced “Team”, in fact, doesn’t exist, it’s a hoax, or a joke at the very least. I know. I’m an Assistant to the Dean of Engineering at San Jose…
