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

Modified: Sep 27, 2016 by Vanessa Beaty · This post may contain affiliate links · 1 Comment

How to Make a Natural Non-Electrical RefrigeratorI 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.

Zeer pots work similarly to refrigeration solutions which were pioneered in ancient times before human beings discovered how to use electricity. Today they are used mainly in Third World countries. They can extend the life of vegetables from days to weeks, which helps to counter the hunger problem.

You can learn how to make your very own zero-electricity zeer pot out of simple materials on Instructables here.

But it is a great way to reduce your ecological footprint and cut your energy bills as well. I am definitely going

    The dryer the climate, the better it works. Often articles cite genuine 'hacks' only to find out they don't work for you. You need ALL the information. It does not work that well in most of the US, damp climates, or cool climates.
