The Mitti Cool fridge from India is a new spin on an ancient design used to keep food cool. According to Virgin’s page on entrepreneurship, the Mitti Cool was designed in the wake of the Gujarat earthquake in 2001. Mansukhbhai Prjapati, a local clay artisan who was affected by the quake, designed the fridge, we’re assuming, as a response to the infrastructure damage that followed the quake. It’s about the size of a mini-fridge you’d find in a college dorm room.
Virgin explains how it works:
“The refrigerator works by using the principle of evaporation. Water from the upper chamber drips down the side and evaporates; removing heat from the inside and leaving the chamber cool.
“Requiring only water to work, the MittiCool refrigerator is capable of keeping food, vegetables and milk fresh for days, using only natural resources. The product is one of a number developed in India by Mansukhbhai Prajapati, who has taken his family’s long tradtions for clay craftsmanship and applied to off-the-grid innovation.”
The design is a spin on the zeer, a clay pot cooler that may have originated in Egypt around 2,500 BC. If you’d like to try the design out for yourself, we found an engineering page that explains the basics.
