Fancy a refrigerator that does not use electricity? An eco-friendly, clay refrigerator, Mitti Cool, proved to be a big draw at the Vishwa Show 2010 which annually showcases green initiatives.
Developed by Gujarat-based rural entrepreneur Mansukhbhai Raghavbhai Prajapati, a school dropout and a National Award winner for innovation, the product has two large water tanks at the top and bottom that cool the sides in the same manner as a clay pot keeps water cool in summer.
Priced at Rs 2,500, the top half of the refrigerator can store 20 litres of water, while the bottom cabinet has separate space for fruits, vegetables and milk.
“It is a suitable invention for villages without electricity. It can also inspire Mumbaiites to save electricity and hence the environment,” said Prajapati, who has also made a non-stick pan, pressure cooker and water filter — all from clay.
“Several such unique micro solutions for macro problems are available at the exhibition. It is not just an exhibition, but also a festival where innovators from different parts of the country offer ‘green’ solutions and wellness alternatives,” said Yogendra Vora, the show’s convener.
Another interesting product was the Watermaker, which allows one to make water from atmospheric air. Working on the principle of condensation, it gathers the humid air and then chills it.
Water droplets are collected in an internal chamber and filtered to remove the impurities.
“The water generator gives best result in coastal areas with temperatures between 25 to 35 degree centigrade and humidity levels ranging from 60 per cent to 70 per cent,” said Amrit Tanshu Patil, the product’s marketing executive.
“The younger generation should imbibe these techniques in their life and also inspire their family to follow,” said Neha Parekh, a teacher who had accompanied students from Sri Sri Ravishankar Vidya Mandir, Mulund, to the exhibition.
