We describe preliminary findings from our recent field trip to Darfur, Sudan, where we aimed to introduce fuel efficient stoves to the internally displaced persons (IDPs) camped there. There are 2 million IDPs in Darfur refugee camps, with another 200,000 across the border in Chad. We visited two camps in South Darfur, Otash and Kalma -- the latter is the largest camp in the world housing more than 100,000 refugees. With our improved stoves we demonstrated fuelwood savings of about 50%. The talk will describe the background and the goals of this visit and our technical and field impressions along with illustrative slides.
