In this Technical Working Papger, he generously shares his experience improving specific technical problems with stoves in Tajikistan, Pakistan and Afghanistan. In this report, he presents and improved pot skirt, stove, and chimney design for street vendors and restaurants. And he considers the multiple challenges faced by poor people in the Himalayas, where it is very cold, and there is very little wood available. This paper includes plans for a modified bread oven that can be used as a space heater in the winter time, as well as carefully considering the many factors that go into building and using the new design.
In addition to the attached paper, Sjoerd has drawings and other information on his web site: http://www.nienhuys.info
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).

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.
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.
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.
Biocharproject.org announces the stumpy biochar combination cooker.
Its a tlud its a rocket stove it has many applications and fully customisable.
Simple design utilises waste LPG tanks to provide safe efficent cheap cooking.
Designed and Made in Australia by Biochar Project and Labrador Mens shed.
An Efficient Cookstove with two burners, two heating surfaces and a small oven:
This stove is designed to work with Vetiver Grass, they also have plans to encourage small scale productions of Vetiver grass straw pellets for use by the wider Haitian community.
* About 30% biochar production
* 3 to 4 days for a batch of charcoal production
* Continuous hot water access (pot 1)
* Highly suitable for institutional cooking and as well making biochar
* Additional heat generated by flaring the pyrolysis gases, used for cooking
* Mitigation of the emissions during the pyrolysis by flaring
* Costs about Rs. 3000 for a 2’ width x 5’ depth x 6’ hight (in feet) “GEO Biochar pit stove”. (cost including, tin sheet for cover, digging the pit, three pot stove and chimney.)
*_"GEO BIOCHAR STOVE" is designed by Dr. N. Sai Bhaskar Reddy, CEO, GEO. Demonstrated to farmers under the project Good Stoves and Biochar Communities Project, being supported by GoodPlanet.org, France
