Rocket Stove

A rocket stove is a super-efficient heater invented at the Aprovecho Research Center to reduce biomass fuel requirements in developing countries. It combines the stove’s air-intake with the fuel-feed slot in an opening terminated by a combustion chamber, which in turn leads to a chimney and heat exchanger. Rocket Stoves are commonly used today in Lesotho, Malawi, Uganda, Mozambique, Tanzania, and Zambia. The stoves are easy to build using local materials, and accept small diameter fuel such as twigs and branches. The resultant heat is directed to a very small area, and greatly reduces the amount of wood fuel needed for cooking and boiling water. Aprovecho won the 2009 Ashden International Energy Champion Award for its Rocket Stove technology. More information.
