“Why not make a refrigerator out of clay?” thought the potter, entrepreneur and inventor Manshuk Lal Raghavjibhai Prajapati from India. In 2002, after three years of hard work on various prototypes, he launched the Mitti Cool – a refrigerator made out of clay.
The fridge consists of two tanks containing 20 liters of water, naturally cooling the inner cabinets of the fridge where fruit, vegetables and liquids can be stored. Manshuk’s invention works on the principle of evaporation: The water dripping down from the upper chamber takes the heat from the inside thus keeping the inner cabinets cool. With a capacity of 50 liters, the fridge can keep food and liquids fresh for several days. As it is a low-cost product that runs without electricity, it can help prevent food spoilage especially in rural areas where power from the grid is rare and financial resources low. In addition, the clay fridge requires no maintenance costs and efforts.
“My aim is to provide all luxurious things to people around the country who can’t imagine affording electronic goods” says Manshuk about his motivation in finding low-cost innovations. He has already invented a motorized hand press machine helping to increase efficiency for potters producing earthen pans and a clay water filter for which he has received numerous awards. Participating in fairs and exhibitions throughout India, Manshuk sells his products both in urban and rural areas. Here you can watch a CNN video about Mashuk and his enterprise Mitti Cool.
