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.

ETHOS 2012, Seattle, Washington January, 2012

The annual lighting of the fires was well represented by various forms of TLUD and T-CHAR units. Christa Roth and Amanda are in the top picture with the prototype of the new Hot Cube. It's a flat pack design that can be assembled by local artisans. The top cube is a biomass burning t-char design, and the bottom cube is an improved charcoal cooker.

In the second photo, Paul Anderson is showing off a brand new T-CHAR protype. The T-CHAR is very much like a TLUD but it has an open bottom. Biomass can be burned to make char over a can or pot to reserve it later, or it can be used over a conventional charcoal stove.

Jet City Stoveworks brought their metal Jatropha Seed Gasifier. It was a windy, wet day, and the stove burned jatropha seeds pretty well. The metal between the gasifier top and the chimney is a warming area that was requested by the community that they are developing the stove for. It gets pretty warm. I may still have the burn on my finger from touching it when it was hot. (I work with hot stoves all the time, and it amazes me how often I forget that metal that's been near fire is frequently hot).

The blue 'tank' is a beautiful looking insulated charcoal stove that Burn Design Lab (Peter Scott and co) has been designing. Burn has is responding to consumer pressure and offering a more effecient, and beautifully designed charcoal stove. They are also planning to sell the latest versions of their biomass cooking stoves this year.

The final two pictures highlight Karsten and the metal TLUD stove that he is building in Uganda. It is well manufactured, sturdy, was my favorite for cooking marshmallows and it sells for just under US$20.

Stovers,
Its a long winter, and old bones and cord wood and Crispin make me
think......

Attached are two pictures which show my early steps towards
understanding the limitations of gravity with stoves.
One shows a wedge shaped door spacer "the Artful Dodger' which picks the stove's pocket for draft and connect it to any burner idea I can cobble together.

The other shows it operating with a burner that has a small unsealed
hopper for pellets. I use a loose lid/follower to ride down on the
pellets. So far there has been no fumes coming up and out, and the fire has not chased the air and fuel back into the hopper. The bottom throat on the hopper is about 5 cm diameter. It operates continuously at one speed with an input of 1.6 kg of wood pellet per hour.

To the members of the list who don't know Energypedia yet: it is an online resource created as a Wiki by GIZ . After some years of development as company-interal resource, it was opened to the public energy community late last year. No registration needed to read.

Dear all,

For over two years we have been telling people that in two weeks or so we hope to have the mud Rocket Stove website updated. It finally happened. Flip has worked countless hours on this. This morning she shouted out, "The baby is born!"

Thanks to Larry Winiarski for all the mentoring and watching over us. Without Larry and the Good Lord this would have never happened. http://www.rechoroket.com/Home.html

Happy New Year,
Jon and Flip

The Sustainable energy Technology and Research (SeTAR) Centre is a multi-disciplinary research facility that operates under the aegis of the Faculty of Science at the University of Johannesburg. The SeTAR Centre was formally launched in March 2010. The centre is housed in a cottage within the University of Johannesburg Research Village on the Bunting Road Campus, with dedicated office space and a testing laboratory in the basement of the Faculty of Art, Design and Architecture (FADA) building.

The SeTAR Centre is engaged on research programmes that focus on energy poverty in both rural and urban areas of South Africa; the role that energy has to play in climate protection in the sustainability of a megacity (Gauteng); the public understanding of science; and networking on energy issues in the Africa region. The SeTAR Centre provides research facilities for energy studies for masters and doctoral students through its affiliation with the Department of Geography, Environmental Management and Energy Studies (GEMES) in the Faculty of Science.

One of the Research Programs is the Basic Energy Programme

The programme focuses on energy poverty and acts as an innovation hub for the development of basic energy solutions for cooking, heating, lighting and productive use for the low income communities. Services and research streams include:

Testing Laboratory
: SeTAR centre has a fully equipped basic energy testing laboratory for use as part of research activities or on a fee-for-service basis. The centre has advanced equipment and automated systems to ensure all tests are carried out satisfactorily and competently. The SeTAR centre was commissioned to characterize thermal efficiency and gaseous emissions of a variety of fuel/stove combinations. In the process of evaluating these stoves, the research staff have also been engaged in the development of written procedures, leading to the Heterogeneous stove Testing Protocol (HTP).

Energy Poverty Research: Focusing on energy access, socio-economics and user needs and aspirations. This assists in designing sector-specific intervention.

Energy Design Innovation: Involved with the design and innovation of safe, clean and affordable basic energy technologies.

Networking and Information: Coordinating a regional (Africa) university-based People’s Energy Network (PEN) and also developing a South African network and industry association.

Attached is the 2011 Annual Report,

BIOMASAS COMBUSTIBLES DEL PERU S.A.C.

POR QUE CARBON ECOLOGICO ?

PORQUE SON FABRICADOS A PARTIR DE BIOMASAS SOLIDAS.

QUE LO DIFERENCIA DEL CARBON VEGETAL:

Dr TLUD (Paul S. Anderson) would like to share recent documents about rice husk gasifier technology and its application from Alexis T. Belonio (Professor and Engineer) of the Center for Rice Husk Energy Technology (CRHET).

The first four documents describe stove developments through CRHET’s collaboration with fabrication shops. These stoves provide rural households and small cottage industries new options for clean cooking using agricultural wastes, like rice husks, as fuel.

  1. Batch Type Rice Husk Gasifier Stove, Model RHGS-12D
    (Document URL: http://drtlud.com/wp-content/uploads/2011/12/rhgs1.pdf )
  2. Continuous Type Rice Husk Gasifier Stoves, Models 10D, 12D, and 14D
    (Document URL: http://drtlud.com/wp-content/uploads/2011/12/rhgs2.pdf )
  3. Firefly (BMG-1040SS), Quickfire (BMG-1050SS), and Wildfire (BMG-1060SS) Biomass Gasifier Stoves
    (Document URL: http://drtlud.com/wp-content/uploads/2011/12/rhgs3.pdf )
  4. A Two-Burner, Continuous-Type Rice Husk Gas Stove (CFRHGS Model 16D-2B)
    (Document URL: http://drtlud.com/wp-content/uploads/2011/12/rhgs4.pdf )
  5. Small-Scale Rice Husk Gasifier Plant for Community Street Lighting
    (Document URL: http://drtlud.com/wp-content/uploads/2011/12/rhgs5.pdf )

The fifth document describes a rice husk gasifier plant which produces enough electricity for community street lighting. This plant was developed by Suki Trading Corporation in Lapu-Lapu City, Cebu, Philippines in collaboration with Kanvar Enterprises and the Center for Rice Husk Energy Technology (CRHET).

OPB did a nice story on stove designers that call the Pacific Northwest (of the US) home.
