• Varun recalls the time, three years ago, when he and some friends were stuck in a hail storm in Uttarakhand. "We made it to a village called Sidri, and took shelter in one of the huts," he recalls. What struck them all was just how suffocating these homes were, as they were hit by the heavy fumes of earthen, wood-burning stoves or chulhas that filled the entire hut. He got in touch with an NGO called The Himalayan Environment Trust, and provided the village with emission-free stoves instead. "They use the same fuel, but compress the energy and reduce the smoke," he explains. Though each stove weighs about four kilograms, it was worth the effort "because once the stoves are in, they stay put." Today, five villages in the vicinity use these stoves, and the children of the village, once trained by Varun, have now taken the prerogative to spread this technology further.
