No Electricity Needed

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. As the water evaporates it removes heat from the inner system, thereby leaving it cool.

One major benefit is that the pot-in-pot enables Gambian farmers to retain food for future sale, instead of dumping all the produce that doesn't sell during a given day.

If the farmers have a storage system, it changes everything. No electricity needed!
