Can you help design a stove that solves this problem?

1. The standard cooking stove in Pakistan: 3 stones with the pot on top

2. Very inefficient: most heat lost out the sides. Every family has to find firewood locally – inevitably deforesting the area.

3. Also very unhealthy – this lady is constantly bothered by smoke

4. Whatever she does, she is constantly rubbing her eyes and coughing. And this happens every day, in every village, and women bear this burden

5. It need not be this way. People said they were really keen to try other methods. They said “just show us another design and we will try it!”

6. Firey debates about how cooking fuel. In this camp for displaced people they explain how they have to pay a lot for firewood or dried dung. Smokey and seriously inefficient, costly and unhealthy: the worst possible approach, yet the one used by everyone!

7. When the trees are gone people use dried animal dung, also smokey. This manure could be put to much better use as fertiliser for growing food or reforestation.
