OED is working with its partners in the Himalayan region to develop a personal heating solution that meets communities' changing needs. HeatSource Textiles is an innovative product that captures and redistributes excess body heat during use, allowing users to spend more time gathering food or tending to herds in extreme cold. Comprised of phase change capsules embedded in traditional Himalayan textiles, HeatSource is designed to replace traditional household heating methods with a clean and mobile solution to warmth.  Climate change has forced many communities in the Himalayan region to alter their daily routine. In many cases - an extended trip to collect increasingly sparse fuel, a longer walk to gather food - nomads are now exposed to extreme cold for longer periods of time. HeatSource keeps people warm without relying on dirty fuels burning, reducing the health burden of indoor air pollution.
