How to Make a Natural Non-Electrical Refrigerator Using Terra Cotta Pots
I am very passionate nigh sustainable living, which is why I am constantly in search of free energy-saving hacks. One thing I recently learned near 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 take one smaller terracotta pot nestled within another and a barrier of wet stand up between them. This sand acts as a wick to move moisture upward the pot walls. It doubles equally a thermal mass to keep the pot cool once its temperature starts to drop. Yous but put information technology in a shady, breezy location, and expect for it to cool. It is similar to the consequence of stepping out of a pond puddle moisture and getting struck by the wind. Imagine how common cold y'all'd go if you let that go on for hours.
Zeer pots piece of 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 tin extend the life of vegetables from days to weeks, which helps to counter the hunger trouble.
You can learn how to make your very own zero-electricity zeer pot out of simple materials on Instructables here.
There are a lot of steps, simply there are pictures for each, so it is easy to follow. I have e'er been very curious how y'all can keep food absurd without electricity, then purely from a science perspective, this project is utterly fascinating to me. But it is a great style to reduce your ecological footprint and cut your energy bills as well. I am definitely going
