In this TED talk Amy Smith talks about the problems of indoor cooking fire fumes and the fuel that is being used in different regions of the world. Did you know over 2 million children die each year from the fumes from such fires? Amy Smith is working with a team of students from MIT to develop devices for producing more effective and cleaner burning fuels. In India for example they are using cow dung which produces a lot of smoke, her team have been trying to replace this with something better. In her last trip to Guinea she could see here efforts in effect, instead of burning normal wood charcoal people are now making charcoal out of corn husks. She also talks about how much deforestation is going on because poeple need wood for cooking but with these alternative fuels wood charcoal might be a thing of the past.
