In the age of modernization and technology, we often take for granted the convenience of having a refrigerator to store our food and keep it fresh. But what if you could have a fridge that does not need any electricity and is eco-friendly too? Sounds too good to be true, right?
Well, meet M Sivasamy, a 70-year-old potter from Coimbatore, Tamil Nadu, who has created a clay fridge that can keep your vegetables, fruits, curd, milk, eggs and other perishables fresh for up to four days without any power supply.
How does the clay fridge work?
The clay fridge is made of two cylindrical pots of different sizes that fit inside each other. The space between the pots is filled with water, which evaporates through the pores of the clay and cools down the inner pot. The inner pot has a lid and a tap to drain out the excess water. The food items are placed inside the inner pot and stay cool and fresh for days.
The clay fridge works on the principle of evaporative cooling, which is a natural phenomenon that lowers the temperature of a surface when water evaporates from it. The water absorbs heat from the surroundings and evaporates, leaving behind a cooler surface. This is how our body sweats to cool down when it is hot.
What are the benefits of the clay fridge?
The clay fridge has many advantages over conventional refrigerators that run on electricity. Some of them are:
- It is eco-friendly and does not emit any harmful gases or chemicals that contribute to global warming or ozone depletion.
- It is cost-effective and does not require any maintenance or repair costs. It also saves on electricity bills and reduces carbon footprint.
- It is portable and can be easily moved from one place to another. It does not need any installation or wiring.
- It preserves the natural taste and nutrients of the food items and does not alter them with artificial cooling agents or preservatives.
- It can be used in rural areas where there is no access to electricity or where power cuts are frequent.
How did M Sivasamy come up with this idea?
M Sivasamy belongs to a family of potters and has been working with clay for most of his life. He learned the art of pottery from his father and grandfather and has been running his own shop for the past 50 years.
He got the idea of making a clay fridge when he saw some people using earthen pots to store water and keep it cool. He thought of applying the same concept to food storage and experimented with different shapes and sizes of pots until he found the optimal design.
He makes two variants of the clay fridge: one is 1.5 feet in length and the other one is 2 feet. They cost Rs 1,700 and Rs 1,800 respectively and Sivasamy has sold more than 100 pieces so far.
He says that his motivation behind making the clay fridge is to contribute to people's health and help the environment. He also hopes that his innovation will inspire more people to adopt sustainable and eco-friendly practices.
I'll try to write that conclusion for you. Here is a possible paragraph:
M Sivasamy is a remarkable example of how innovation and creativity can solve everyday problems and make a positive impact on the society and the environment. His clay fridge is not only a simple and effective way of preserving food, but also a testimony of his passion and dedication for his craft. He deserves our admiration and appreciation for his ingenious invention that can benefit millions of people across the country and beyond. Hope that his story will inspire more people to follow their dreams and use their skills and talents for the greater good.
