A thermal-battery powered cooling device could help farmers in India save millions of litres of milk every year
India has the highest number of undernourished people in the world. According to the United Nations Food and Agriculture Organisation (FAO) that figure currently stands at 217 million and more than 30% of children are born underweight.
Against this backdrop, lack of refrigeration in rural India is leading to millions of tonnes of fresh produce going to waste every year. India is the largest producer and consumer of milk in the world; 130m tons of milk are produced annually by rural farmers in India, yet a significant proportion of this is lost.
