We found a video by mixcatcom to teach you how to cool your food and drinks without electricity. This is a fascinating survival tip that makes use of the natural laws of physics in a clever yet simple way. It’s a true “low tech” solution.

Long before refrigerators were invented, people used different methods to chill their food so that it would last longer. There is some evidence that the principle of evaporative cooling was used in Ancient Egypt, at around 2500 BC. There are frescoes that show slaves fanning water jars – a method that increases the air flow around the porous jars. There are also many earthenware pots that were used in the Indus Valley Civilization at around 3000 BC.

In the early 20th century century people would buy a block of ice and fan it for a cooling breeze.

Koreans store their kimchis in clay pots and keep them cool underground. The temperature has to be controlled so that the kimchi attains perfect fermentation.

Another example is by using a mixture of salt and ice. This process makes it possible for people to make ice cream. This is due to the fact that salt causes a temperature drop that slows the melting rate of the ice.

Another way of storing food is the pot-in-pot method. Zeer pots use this principle of evaporative cooling. This is a natural phenomenon in which the evaporation of a liquid cools the liquid and anything else in contact with it.

Take note that this method of storage will only work if the pot is placed in a dry area. Like a swamp cooler – if it’s too humid, it won’t be able to “work its magic”.

The pot-in-pot technique was almost forgotten because of the advent of modern technology where people rely on electric-powered refrigerators to store their food.

However in 1995, Mohammed Bah Abba, a Nigerian pot maker, wanted to help the livelihood of poor Sudanese families. Freshly harvested vegetables don’t last after a few days because of the warm temperatures. He played around with different clay pots and developed a unique pot-in-pot creation that helped preserve their vegetables for a longer period of time. This earned him the Rolex Award in 2000 https://www.youtube.com/watch?v=7LUc5U5isVk and the World Shell Award for Sustainable Development in 2001.

It would be nice if the Zeer pot becomes more popular in other third world countries so that people who don’t have money to pay for electricity (or live in areas too remote) can also have the opportunity to store their food in the most economical way.
