Indoor air pollution from burning solid fuels like wood causes 4.3 million premature deaths each year, is the leading cause of premature deaths among children, and is a major contributor to climate change. Firewood harvesting is responsible for half of global deforestation and can lead to the assault, abduction, or rape of the women and girls responsible for gathering it. Unstable and unsafe cooking techniques frequently cause debilitating, life-altering burns. This toll on human health and well-being is paid almost exclusively by women and children. The InStove offers dramatic improvements over traditional cooking techniques. It is safe, stable, and vents to the outdoors to protect people from the effects of indoor air pollution. Its high-efficiency design reduces fuel use by 75-90% and harmful emissions by more than 90%, dramatically reducing the time, cost, and danger associated with collecting fuel, as well as pressure on our forests and atmosphere.
