Sonam Wangchuk, an engineer and educational reformer from Ladakh, has invented solar-heated tents for Indian soldiers facing the bitter cold of the region. The character of Phunsukh Wangdu in the Bollywood film ‘3 Idiots’ was inspired by Wangchuk’s life. He built a sunlight tent for the army in the Galwan Valley. A tent can accommodate as many as 10 soldiers. Weight is less than 30 kg. It can operate even at a temperature of minus 14 degrees Celsius. No kerosene is needed and since it is carbon neutral, there is no air pollution as well.
Wangchuk had previously built solar-powered mud tents. Earlier, he had called on Indians to boycott Chinese companies and products amid growing tensions between the neighbours.
