Since living in Botswana, Amy Smith has dedicated her life to solving daily problems in the developing world. From machines that produce clean drinking water, vaccines and cheap charcoal, the MIT instructor’s inventions are made with local materials.

Beyond making life easier for the world’s poor, Smith also wants to change what it means to be an inventor. In a world obsessed with gizmos costing hundreds of dollars, Smith wants instead to focus minds and imaginations on simple solutions for big problems.
