To facilitate getting cookers into the hands of people who need them, Diassana has sold cookers at half price or on credit. He has been able to follow up directly with most of the users and observes that they are using less conventional fuel. He estimates that about 950 people have directly benefited from his cookers, while 10,000 more have witnessed solar cooking at his exhibitions and demonstrations. Radio and television coverage has spread the word further. Diassana reports that the effects of deforestation have become increasingly visible near Bla in the past few years, and that his work with solar cooking is meant to address this problem while also helping women save money and time and reduce their exposure to smoke.
