Default Evaporative cooling and desalination

Once I saw a water container in St Augustine made by the Spanish in
the 1600s from permeable coral. They put water into it and water
wicked through it and evaporated causing the water inside to become
cooler. I could not ascertain its effectiveness because the museum
had it in the shade out of the wind too.. Perhaps one could make
something like this from modern lightweight materials.

When I was a scout about 40 years ago, we had "Lister" (spelling
strongly suspect) bags that did just that. The water kept the canvas
sides damp, the wind evaporated the water and cooled the contents
slightly.

A variation of that put a can of water above a sack draped over some
shelves. Worked somewhat as a camp refrigerator.
