In Rajasthan, India, where summer temperatures can soar to nearly 50 degrees Celsius, a traditional cooling system known as the 'desi fridge' has been used for over a century to keep food fresh without electricity. Constructed from locally sourced materials such as clay, cow dung, and grass, this ingenious method relies on the porous nature of clay for slow evaporation, which cools the air inside. The khipra grass roof provides additional insulation, allowing items like milk and curd to stay fresh for extended periods and keeping rotis soft even in extreme heat. Despite its effectiveness, this method is fading into obscurity as modern refrigeration becomes more prevalent. Other regions, such as Kerala, also utilize sustainable practices, like the 300-year-old kaavi flooring, which keeps homes cool using natural materials. These traditional techniques highlight the importance of eco-friendly solutions in a world increasingly reliant on technology.
