How a Clay Fridge Without Electricity Is Changing Lives Around the World
In a world where cutting-edge technology often comes with a high price tag and environmental cost, one Indian entrepreneur is proving that innovation doesn't have to be expensive or high-tech. Sometimes, the best ideas are simple, sustainable, and inspired by tradition.
This is the story of Mansukhbhai Prajapati, a potter from the small town of Morbi in Gujarat, India, who turned a centuries-old tradition into a life-changing invention: the MittiCool clay fridge—a refrigerator that works without electricity.
The Humble Beginnings
Mansukhbhai was born into a family of potters. From a young age, he would walk six miles each day with his mother to collect clay for their pottery business. Though the work was hard, the income was meager. Pottery, in many parts of India, is seen as a low-status job. Yet, Mansukhbhai believed there was value in the craft that had sustained his family for generations.
But life took a difficult turn in 2001, when a massive earthquake struck Gujarat. His home was destroyed, and so was his stock of clay pots. Among the rubble, a journalist covering the disaster described broken clay pots as the "poor man's fridge" because they could keep water cool even during the hottest months.
This remark stuck with Mansukhbhai—and planted a powerful idea in his mind.
The Birth of the MittiCool Fridge
Inspired by that comment, Mansukhbhai began experimenting with clay in a new way. He wanted to create a refrigerator made entirely from clay that would not require electricity. He had no formal engineering education. Still, with determination and creativity, he started working on prototypes.
Over the next four years, he tried many designs and faced constant challenges. He invested all his savings and took loans, accumulating over $22,000 in debt. Many around him doubted his dream, but Mansukhbhai persisted.
Eventually, his hard work paid off. He built a working prototype of the MittiCool Fridge. It had a clay tank on top to hold water, which slowly seeped down through the porous sides. As the water evaporated from the clay surface, it cooled the interior—a process called evaporative cooling.
Inside, there were storage shelves for vegetables, milk, and water. The simple device could keep vegetables fresh for up to 5 days and milk safe for 24 hours—without using a single unit of electricity.
Affordable, Eco-Friendly, and Revolutionary
The MittiCool fridge is sold for about $95 (₹7,500 INR)—making it accessible for families who don’t have regular access to electricity or who want an eco-friendly alternative. It’s now sold in over 300 retail outlets across India, and exported to countries like the United Kingdom, Kenya, and the United Arab Emirates.
But the fridge is more than just a product—it represents a new wave of frugal innovation, where low-cost, sustainable solutions are built for real-world challenges. Mansukhbhai's work has been recognized internationally. He has received awards, praise from scientists, and even visits from dignitaries who admire his grassroots innovation.
A Model for Sustainable Innovation
The success of MittiCool shows that we don’t always need expensive gadgets to solve big problems. Across many developing regions, access to electricity is still unreliable or too costly. But the need to keep food fresh and safe remains critical.
Mansukhbhai's fridge offers a sustainable, zero-emissions alternative that could be a blueprint for similar solutions around the world.
His story is a reminder that true innovation often begins at the grassroots level—fueled by local knowledge, personal passion, and a deep understanding of community needs.
