They use biomass fuels like wood, crop waste, animal waste or coal. These solid fuels may be the least costly fuels available. But they are also a major cause of health problems and death.
For more than thirty years, the Aprovecho Research Center has been designing cleaner, low-cost cooking stoves for the developing world. Dean Still is the director of the group which is based in the United States. He notes a World Health Organization estimate that more than one and a half million people a year die from breathing smoke from solid fuels.
DEAN STILL: "And half of the people on planet Earth every day use wood or biomass for cooking. These are the people on Earth who have less money, and the richer people use oil and gas. It's been estimated that wood is running out more quickly than oil and gas. And so it is very important for the poorer people to have very efficient stoves that protect their forests and that protect their health."
Every year Aprovecho holds a "stove camp" at its testing station in Cottage Grove, Oregon. Engineers, inventors, students and others come together to design and test different methods and materials for improving stoves.
