The Indian Institute of Technology Bombay (IIT Bombay) has unveiled an innovative prototype aimed at heating homes sustainably during the harsh winter months in the Himalayas. Utilizing strontium bromide, a salt compound, the prototype captures and stores solar heat collected during summer.

This clean and smoke-free alternative offers a significant improvement over traditional diesel heaters and firewood, often relied upon by Himalayan communities. The unit, which can store about 500 kilowatt-hours of energy, is designed to be portable and easy to operate, with potential for recharging solar stations in sun-rich areas like Gujarat or Rajasthan.

Successfully tested in lab conditions and with the Indian Army, the technology promises long-term cost savings and environmental benefits. While initial costs are higher than other heaters, over time, the economic advantage, bolstered by reduced fuel and carbon emissions costs, becomes apparent.
