Sorry for any cross postings

We have a patron that is looking for information on the Coolgardie Meat safe or similar products. We found information on this item at an Australian Museum. " A Coolgardie safe helps keep perishable food items cool, free of insects and therefore fresh. It relies on the principle of evaporation absorbing heat. This particular safe is made of metal and may have been purchased rather than home made. All coolgardie safes work using the same principle of heat being dissipated by evaporation. The safe is placed in a spot where it will be in the breeze, if any, and shade. Water is used to wet the fabric sides in the safe. The heat of the climate evaporates the water off the sides of the safe creating a cooler interior. "
This is from the Powerhouse Museum site (a museum in Australia).
I am sure there are similar products in the US and Canada, any ideas?
The patron is looking for a detailed description and how it is used. Also maybe how to create one. Thanks. 
Thanks for your help. You can respond off list.
