Nearly half the people on Earth use inefficient fuel sources like wood or coal to cook their food. Every year three to four million people die from illnesses related to smoke inhalation from cooking this way, as smoke from open fires contains high amounts of toxic chemicals which can cause a variety of illnesses, including lung cancer and stroke.

To help combat this global health issue, UC Berkeley student Danny Wilson has developed a specially designed efficient cookstove. Wilson and his team are distributing these stoves to places like Sudan, Darfur and Ethiopia where the problem is quite prevalent.
