Mitti Cool Refrigerator

Mansukhbhai Prajapati

The Mitti Cool Refrigerator is a low cost refrigerator made of clay that can run without electricity. The innovative fridge cools water naturally while keeping food such as vegetables, fruits, and liquids fresh for several days. Mansukhbhai Raghavbhai Prajapati, a Gujarat-based potter, makes this fridge that uses no electricity.

The refrigerator works on the principle of evaporation. It has two large tanks, one at the top and and the other at the bottom with a capacity to store approximately 20 L of water. The fridge also has a cabinet to store food items. The water tanks cool the sides of the fridge in the same manner as clay pots used to cool water during summers. The water from the upper chamber drips down to the sides, taking the heat from the inside thus leaving the chambers cool. This helps to preserve the food for days. “The refrigerator is a natural cooler. Unlike the fridges used normally in homes, the water that is stored in the clay tanks is cooled naturally. This has several health benefits as well. This also helps preserve food items like fruits and vegetables, which can be stored up to six days, and liquids like milk up to three days.
