Many developing countries use traditional wood fuel stoves without proper ventilation, which produces indoor concentrations of smoke particles "typically 10 to 100 times the long-term levels recommended by the World Health Organization." Chronic exposure to these particles are linked with disease. Aprovecho rocket stoves were sold in Lesotho, Malawi, Uganda, Mozambique, Tanzania, and Zambia. Aprovecho won the same award in 2006 for their rocket stoves. A stove was designed to make tortillas based on the principles of the rocket stove and won an Ashden Award in 2005.
Larry Winiarski, Technical Director of Aprovecho, began developing the rocket stove in 1980 based on a VITA stove, designed by Sam Baldwin, and rediscovered the principles of the systems developed by the Romans in hypocaust heating and cooking systems. As well as being used for lighting, this design was also used for cooking and for heating water due to its "affording much the strongest heat without smoke." This was a major development of the traditional oil lamp, which introduced a glass chimney above the flame to increase air-flow. History Ī precursor to the rocket stove was the Argand lamp, which was patented in 1780. In field tests in India, rocket stoves used 18 to 35 percent less fuel, compared to the traditional stoves, and reduced fuel used 39-47 percent, compared to the simple, traditional, open, three-stone fire.

Rocket stove designs are most often used for portable stoves for cooking but the design is also used for large, fixed stoves in institutions, and to make rocket mass heaters for heating. Fuel is burned in a simple combustion chamber containing an insulated vertical chimney, which ensures almost complete combustion prior to the flames reaching the cooking surface. A small manufactured rocket cooking stove A rocket stove Rocket stove illustrationĪ rocket stove is an efficient and hot burning stove using small-diameter wood fuel.
