A cook stove is heated by burning wood, charcoal, animal dung or crop residue. Cook stoves are commonly used for cooking and heating food in developing countries.
Improved Cook Stoves (ICS) are designed to reduce the fuel consumption per meal and to curb smoke emissions from open fires inside dwellings. They are designed for developing country settings as a low cost bridging technology. It is generally claimed that the new designs burn the wood (or other fuel) more efficiently. Evidence refers to significant reductions on firewood consumption, time consuming wood extraction and respiratory diseases. Important features may include a pipe (chimney) to vent the smoke and a different chamber design.
There are various designs, such as the ONIL Stove which uses mortar-less concrete blocks in its construction and costs $150 USD per stove and the LORENA stove which was designed with the mistaken belief that rammed earth would act as insulation; there was a basic misunderstanding of the difference between mass and insulation. Good insulation resists the passage of heat; thermal mass does the opposite, it absorbs heat. Testing has shown that the rammed earth used in the Lorena stove absorbs heat that should be directed toward cooking.
The Justa Stove has been deployed in Honduras by Trees, Water & People and AHDESA, for which they jointly won an Ashden Award in 2005. An improved Justa Stove jointly developed by the non-profit Proyecto Mirador and the Aprovecho Research Center called the Dos por Tres is being disseminated in Honduras with more than 20,000 stoves installed as of 2011. The Dos por Tres has been registered as Project 690 and certified by the Gold Standard Foundation to reduce greenhouse gas emissions by 2.7 tons per year.
The Patsari stove shares similar benefits with the Justa Stove, and is also used in Central America. Their proponents claim that these stoves use approximately 1/3 of the fuel required by traditional three stone stoves, lessening the daily labor devoted to gathering wood and also preventing deforestation.
The Ecocina stove was designed by StoveTeam International and is manufactured at a central locations from cement, pumice, and ceramic tiles. It resembles a large flower pot, with a steel cooking surface which can also receive a pot. It is actively produced in several countries, including Guatemala, El Salvador, Honduras, Nicaragua and Mexico.
Unlike its brick and mortar counterparts, the Ecocina stoves have no flue and are manufactured in a factory. They are then placed in a home on top of a table or similar raised surface. Again, as with their brick and mortar counterpart, the Ecocina stove employs a rocket stove combustion chamber and promises the same reduction in consumption of fire wood and reduction in fumes emitted into the home. It also remains cool to the touch, preventing burns.
