Food Cooling Without Refrigeration: Desert Fridge

Food Cooling Without Refrigeration: Desert Fridge

Postby jpf1030 » Wed May 25, 2011 5:42 pm

Howdy All,
Though we are working on a tad complex solar ice maker to supply ice for ice boxes, there are other alternatives. A year or so ago, we were researching and found articles on a young gal from England that developed an evaporative cooler in Africa for her college work. Today I received a newsletter on a little more primitive method being employeed
in Gambia, Africa which is pasted below with the link to a 3 1/2 minute video on the Desert Fridge. It is ultra simple to make. It would certainly be worth having some extra clay pots around for this purpose along with a stash of sand. It would surely add a good degree of back-up emergency refrigeration for when the massive power outages come...jpf

The Pot in Pot method of keeping food cool in hot climates is
even becoming popular among people in the West who wish to
reduce their dependency on a big energy sucking refrigerator.

The method is very simple: There are two clay pots, one
inside the other. In between there is sand that is filled
with water a few times a day, which evaporates and removes
heat.

This video is filmed in Gambia, and shows us that if the
farmers have a storage system, it changes everything. No
need to dump wilting produce at the day's end anymore.

Keep it cool and sell it tomorrow.

No electricity needed!
