How to Make a Natural Non-Electrical Refrigerator Using Terra Cotta Pots

How to Make a Natural Non-Electrical Refrigerator

I am very passionate about sustainable living, which is why I am constantly in search of energy-saving hacks. One thing I recently learned about which I never knew existed before is a “zeer pot.”

A zeer pot is simply an electricity-free “fridge” for vegetables. It works through evaporative cooling. You have one smaller terracotta pot nestled inside another and a barrier of wet stand between them. This sand acts as a wick to move moisture up the pot walls. It doubles as a thermal mass to keep the pot cool once its temperature starts to drop. You just put it in a shady, breezy location, and wait for it to cool. It is similar to the effect of stepping out of a swimming pool wet and getting struck by the wind. Imagine how cold you’d get if you let that go on for hours.
