3 billion people cook with biomass, primarily wood. This causes disease and death, fires and burns, deforestation and climate change.
3-stone and other traditional wood cookstoves are extremely inefficient. They use too much wood and emit too much smoke. Our designs make the fires more efficient, reducing the use of firewood and reducing smoke.
One important principle in our designs is to elevate the firewood to allow air under the fire. The air under the fire makes the fire burn more efficiently. Less wood is needed and less smoke is emitted.
