I read this on SHTFplan.com and I thought I should pass this on GT.com.

The zeer, or clay pot refrigeration keeps food cool (icy cold) without electricity by using evaporative cooling. Essentially, a porous outer earthenware pot, lined with wet sand, contains an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed. The evaporation of the outer liquid draws heat from the inner pot.

wonder if the inner pot could be metal.

could be a way to cool some drinks for a power-out-cook-out.


reminded me of "desert water bags", using evaporation to cool water.
