Some supressed notions for fridges were solar powered, compressed gasses, working like ammonia fridges, but using concentrated solar heat during the day for fuel. Expensive to build, and technically complex, once built, have no moving parts and work as long as there is sun! Some similar ideas are found here!

this is not new ,,,,ages old idea still found in ‘desert coolers’ and doubled walled thermoses filled with wet hay or rags and made from anything—used in Africa and Bangla Desh.

I’m sorry, I’m not sciencey at all, but surely the point here is that Emily has taken a simple design and put it to good use?

Sounds like basic evaporative cooling to me. Here is a magic trick for anyone that thinks this is revolutionary…

1. buy a 20oz bottle of soda and test it’s temperature

2. put the bottle inside 2 wool socks

3. dip the whole thing in water

4. lay it out in a dry area (dry climate) to dry (re-wetting it every so offten

5. after several hours, compare the temp of the soda to the starting temp

Sounds more like a keg party.
