In our country around 40% of the food produced gets wasted even before it reaches your plate, moved by this fact , a class 12 student, Dikshita Khullar, from G.D. Goenka Public School, Vasant Kunj, New Delhi made a prototype of a ‘magic-fridge’ which can run without electricity and can help combat food wastage issues. The young innovator has simply used bricks, sand, jute bags and bamboos to make this prototype of the magic-fridge which can hold up to six crates or 120 kg of vegetables and can keep the veggies fresh for seven days.
Her innovation consists of one big rectangular structure constructed with bricks and another small rectangular structure that is built inside the big rectangular chamber. Using the basic science phenomena, some space has been left in-between both of these structures, and the gap has been filled with sand. The upper part of the chamber IS covered with the bamboo lid and that’s all that there is to this simple innovation.
All the user has to do is water the chamber every 2-hours because that’s what will keep the inside area cool. This chamber can keep the temperature 10-15 degree Celsius lower than the outside temperature and maintain about 90% relative humidity.
