Mitticool is a natural refrigerator made entirely from clay to store vegetables, fruits and also for cooling water. It provides natural coolness to the stored material without requiring any electricity or any other artificial form of energy. Fruits, vegetables and milk can be stored fresh without deteriorating their quality for 2 to 3 days retaining their original taste. It works on the principle of evaporation. Water from the upper chambers drips down the side, and gets evaporated taking away heat from the inside, leaving the chambers cool. The top upper chamber is used to store water. A small lid made from clay is provided on top. A small faucet tap is also provided at the front lower end of chamber to tap out the water for drinking use. In the lower chamber, two shelves are provided to store vegetables, fruits and milk etc.
