Refrigerate Without Electricity


Put a smaller pot in a larger pot, they must be clay/earthenware and unglazed, fill up the space between them with sand, water the sand and cover the pots with a wet cloth,

when the sand dries, it pulls out the heat to keep the inside cold.

This refrigerator named Zeer Pot is very popular in northern Nigeria because it’s cheap, natural and runs with out electricity, this invention won a Rolex Award and is being used to help people of Third world countries to preserve food.

It’s easy to make, you can have a try.
