The most common method of cooking for impoverished people in developing countries is the three-stone fire, which not only requires large amounts of wood (that children are often sent to fetch rather than going to school), but it also produces unhealthy amounts of carbon dioxide. Swedish design studio Claesson Koivisto Rune devised a simple solution to ease this burden via the Baker Cookstove. Made from recycled aluminium, the brightly hued stove uses less than one third of the wood needed for the three-stone fire and reduces carbon dioxide emissions by 56%.
