Jiko Kenya–fuel-efficient cook stove featuring an innovative in-built jacket that can be filled with 3 liters of water that enables the user to simultaneously boil water thus sanitizing it whilst cooking enabling households to have safe drinking water free of disease-causing micro-organisms. The stove through pilot studies was able to save a household USD 17.85 monthly with fuel reduction from USD 23.81 to only USD 5.96 monthly which translates to a 75% reduction in fuel costs and zero cost in water sanitization which has contributed to the reduction of water-borne diseases.
