Her extremely low cost food preservation setup will help fruit and vegetable vendors and arrest massive food wastage

A ‘magic fridge’ that runs without electricity has been designed by a Class 12 student, Dikshita Khullar. The fridge is expected to help farmers and middlemen who deal with fruits and vegetables every day.
According to government statistics, India wastes roughly 67 million tonnes of food every year. This is more than the national output of Britain. 
The most important reason for the food wastage appears to be the lack of storage facilities that cripple farmers and vegetable/fruit vendors
This Class 12 student from GD Goenka Public School, Delhi,went about tackling that serious issue.
Dikshita said she had always been inclined to finding sustainable solutions for environmental issues she revealed in a recent TV interview.
“Through the concept of evaporative cooling, which is when liquid water evaporates from a surface and hence decreases the temperature, the prototype was built with easily available materials such as bricks, sand, jute bags and bamboo sticks, which are cost effective for farmers too” said Dikshita.
Describing the intricacies of the model, she said, “Imagine one big rectangular structure constructed with bricks and another small rectangular structure built inside the big rectangular chamber. The catch is to leave some space in-between both of these structures so that it can be filled with sand. The upper part of the chamber is covered with the bamboo lid and that’s all that there is to this structure.”
This fridge is estimated to cost Rs. 4,000, with a capacity of holding 6 crates or 120 kg of vegetables, which can be kept fresh for up to 7 days.
 “The methodology is simple, the vegetable vendors have to 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,” she shared with the channel.
The first model of the prototype was built in her hometown village of Sultanpur in Delhi and then another one in the Manger village in Haryana.
The fact that millions die of hunger every year is astounding considering the fact that India is the second largest producer of wheat in the world. “I want to put an end to this sad yet true reality,” she said..
