This refrigerator is extremely simple and does not require power, making it suitable for use in desert environments without easy access to electricity or repairs.

It consists of a small glazed earthenware pot placed inside a larger unglazed one, with the space between the two filled with moist sand.

The inner pot is filled with whatever is desired to be cooled (fruit, vegetables, drinks) and covered with a wet cloth.
