Episode 117: How can a cook stove change the world? Three billion people burn traditional biomass and coal indoors in cook stoves. These stoves are having a tremendous impact on our environment and on the health of those who use them. Some of the health problems associated with non-improved cook stoves include increased rates of asthma, indoor air pollution, (CO2, methane, and nitrous oxide), and respiratory infections. Cook stove use also contributes to climate change and deforestation. 
For over thirty years, the Aprovecho Research Center has been designing and implementing improved biomass cooking and heating technologies in more than sixty countries. Aprovecho is the world leader in open source development of all aspects of improved cooking stoves.
In this episode, Dean Still, Aprovecho's Executive Director, talks about the benefits of improved stoves, Stove Camp, and why it's important to "find a problem that entrances you".
