After working as a tea-seller, he joined Jagdamba Potteries, a rooftop tile manufacturing facility in 1985 where he earned a wage of Rs 300 per month. But with a zeal to do something different, Mansukhbhai left his job in 1988 and took a loan of Rs 30,000 to start his own earthen plate manufacturing unit.
Mitticool has to its credit a horde of achievements and awards. All thanks to one man, whose determination led him to do something different which benefited the society at large.
That is indeed one true scientist.
The rural innovator is researching on low cost houses which can adjust temperature according to the climate outside. The houses will not just be for the economically poor people, but also for the richer class to encourage sustainable living.
Remember the amazing Mitticool refrigerator which runs without electricity and also preserves the original taste of the food items? The inventor of that unique refrigerator, Mansukhbhai Prajapati, has now come up with an idea of a house that requires no air conditioner or fan and yet remains cool during summers. Not only this, the house adjusts the temperature itself according to the climate.
Sounds incredible. Right? Imagine how much we can save on the huge electricity bills every year. Prajapati is working to create eco-friendly and low cost houses which will have natural lighting and cooling.The dream houses will have no external electricity and will run on renewable energy. Made of clay, natural material and simple physics, the alternate energy will help maintain a comfortable temperature indoors.Gujarat government has given Prajapati a land in Wankaner where he will carry out research on his green homes. He is currently testing soil and doing basic research to come up with the first model which is expected to be ready in next six months.
Prajapati’s idea is to make affordable houses which are not just useful for the poor but can also be used by the richer class for sustainable living.
The devastating earthquake of 2001 destroyed thousands of homes in Gujarat, but the destruction sparked an idea in the mind of Mansukhbhai Prajapati.
Prajapati had been making earthen water filters but a benign news caption about his broken water filter wrought a change in perspective.
In February 2001, a Gujarati newspaper carried a photo feature on the earthquake. Among the photographs was one of a broken water filter produced by him, with the caption: ‘the broken fridge of poor’.
"This got me thinking and I actually started working on a refrigerator that would keep food cool without needing electricity," said Prajapati about the pradigm shift in his thinking.
After a painstaking three years during which he tested all sorts of soil, clay and refrigerator designs, Prajapati finally came out with his unique "Mitticool" fridge in 2005.
Mitticool is made of a specific type of terracotta clay with numerous pores on its walls. Its function is simple: keep things cool, for which it uses the basic principles of physics.
About 10 litres of water travel through it, circulating through the pores and eventually evaporating. The evaporation lowers the temperature of the clay, and keeps things stored in the ‘frig’ fresh.
"Mitticool can keep the food fresh for five days," Prajapati explained.
