MittiCool clay refrigerator cools food without electricity
According to the Food and Agriculture Organization of the United Nations, while a large number of people in the world go hungry, 1.4 billion tons of food a year is thrown into landfills. Food is thrown away for a variety of reasons – in developed countries due to its excess, and in poor countries, the reason is often the lack of ability to save food for longer – there are no refrigerators or even electricity.
Indian inventor Mansukhbhai Prajapati has come up with a refrigerator that won’t solve the problem for the world, but it does help to save food for more time on a local scale.
The MittiCool refrigerator is made of clay and does not need any energy to work. According to its inventor, the refrigerator is able to store vegetables and fruits for a week and even dairy products can be stored in it. Prajapati started developing MittiCool back in 2001 and now sells around 230 units per month in India, Kenya and the United Arab Emirates.
MittiCool is made from a special, porous type of clay, which in the Gujarat region, where the Prajapati workshop is located, is an excess. The refrigerator operates on the principle of evaporation. It consists of the upper and lower chambers. In the upper chamber is water, which gradually seeps through the walls down into the lower chamber and evaporates cooling the clay. In the lower chamber there are two shelves for storing food. Using this mechanism, the temperature inside MittiCool is up to 8 degrees Celsius lower than outside.
Thus, MittiCool does not require energy to work and does not pollute the atmosphere. Its use significantly extends the shelf life of fruits, vegetables or dairy products. Plus, it costs only about 50 US dollars. Such a refrigerator is an excellent solution to problems in remote villages of India and other countries. The disadvantage of MittiCool is that the production of one refrigerator by hand takes about 10 days and it turns out to be quite heavy. It takes at least two men to move one refrigerator.
