We are now introducing improved cookstoves to the developing world. Worldwide, 3 billion people cook over open fires. These fires are filthy, unhealthy (smoke), dangerous (fires), expensive and time-consuming (wood collection), cause deforestation and are horrible for the climate.
Our new cookstove design is so simple it can be made by brick makers everywhere using only the clay they already use for bricks. It is just two modified bricks. Women are using our stove in Uganda, Tanzania and Rwanda. They love it. It uses much less firewood and emits much less smoke.
We are spreading the design throughout Uganda, Rwanda, Tanzania, Kenya and numerous other countries. Brick makers should be able to make and sell the stoves for around $1.
