Our site is dedicated to helping people develop better stoves for cooking with biomass fuels in developing regions.

For additional detail and information, join the Cooking Stoves Mailing List, browse the archives, read about current projects and ask other cooking stove builders, designers, and organizations disseminating improved stoves around the world.

MIT has recently published the paper "Up in Smoke" by Rema Hanna, Ester Duflo and Michael Greenston which studies the a randomized installation of the Chullah in India. The study participants received skilled help in installing the Chullah stove and minimal help in maintaining them.

A Geyser, is a hot water heater in South Africa. There are many houses that are not connected to conventional utility grids, and heating water with electricity and natural gas is expansive and/or impractical.

Tankless, batch hot water heaters directly connected to the shower etc, are a great single-use application for an efficient stoves.

Rogerio Carneiro de Miranda shared his new video that highlights the features of the Ecofogão in Brazil.

It is is a rocket style stove that uses wood to heat a cast iron griddle and an oven. It is an efficient stove that also includes an chimney, and the option to build it into an attractive and functional kitchen island. They also have an option that heats water (for washing or bathing).

For more information, and pictures, and to buy the stove, see their website:

Dennis Hartley, who volunteers for Aprovecho put together a nice video about the
2012 ETHOS Conference.

They have developed a various biomass stoves ( Kompor Biomass ) The fuels also vary from chopped woods/twigs, pellet, palm kernel shell, hazelnut kernel shell, corncob, etc..

And they have a nice collection of YouTube videos:

All stoves presented above are of TLUD types, but the combustion is improved by using pre-heating and counter-flow burning mechanism. The one intended for palm kernel shell utilizes diffused-combustion mechanism, in addition to pre-heating and counter flow mechanism.

The latest one

is devoted for institutional cook stove or small restaurants.

Very recently, we have also developed a new rocket stove. The combustion in this new rocket stove is improved by introducing counter-flow burning mechanism.

Contamination of drinking water sources by synthetic organic compounds (SOCs – e.g. pesticides, pharmaceuticals, fuel compounds, etc.) is a growing worldwide problem. Many of these chemicals bio-accumulate in the human body and cause cancer, birth defects and diseases of the reproductive system, and disrupt endocrine and neurological systems. However, few low-cost, sustainable and appropriate treatment technologies are available to rural and developing communities for SOC removal.

Water filtration using charcoal is an ancient practice that continues today in non-industrialized regions around the world, though it has not yet been rigorously demonstrated for removal of modern industrial pollutants. Unfortunately, charcoal production by traditional kiln systems is often a resource-intensive and highly polluting process, and kiln processes are typically not optimized for production of good water filter char. Low cost, energy efficient, environmentally sustainable and scalable local production of optimal water filter char can be accomplished with biomass gasification (e.g. cookstoves and larger units using the TLUD design).

The video and print resources available on the Aqueous Solutions website (www.aqsolutions.org) are intended to

  1. summarize current results of collaborative field and laboratory research pertaining to the use of traditional kiln charcoals and gasifier chars in decentralized water treatment that targets SOCs,
  2. provide instructional materials for construction and operation of small- and intermediate- scale gasifier char production units using local materials, and
  3. provide instructional materials for integration of biochar filtration into a multi-barrier small- and intermediate- scale water treatment systems constructed from inexpensive and widely available materials.

Did you know that more then half of the price of a bag of charcoal in Nairobi is money needed for paying bribes to get illegal bush charcoal to town? Save your money (and Kenya's forests) by making your own charcoal at home using only your own twigs and pruned tree branches. (or timber mill waste)

The Greenway Smart Stove is an insulated metal stove, that appears to be a rocket style design with bakalite handles and a metal pot rest and fuel rest. You can see more details in the Greenway Smart Stove flyer.

This stove is marketed as an improvement over the mud Chulha, which is familiar in India.

UNEP and the GACC is working with (COAM) the Conservation Organization of the Afghan mountains.

There are a couple of additional pictures of their stoves here:
