Engineer, innovator turned education reformer Sonam Wangchuk has developed a solar-heated military tent for the Indian Army at Galwan Valley. The solar-heated tent was developed at the Himalayan Institute of Alternatives in Ladakh. The tent is highly insulated in the north, east and west direction and in the south, there is a heat storage bank that collects the sunlight in the daytime and releases heat at night. All parts of the tent are light in weight which can be easily carried by the soldiers. For 10 jawans, fully portable all parts weigh less than 30 kgs. For soldiers stationed in strategically important and high-altitude locations like the Black Top Hill or Siachen Glacier, this tent offers comfortable and non-polluting shelter. It replaces tons of kerosene and pollution climate change.
