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.

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.

and the movie:

Flip and Jon Anderson put together a beautiful earthen oven that's powered by a Rocket stove. They've got all of the details on their picassa photo album:

They were inspired by Kiko Denzer's book Build your Own Earth Oven to build the supports with apple pruning into an inverted basket, and then mix the clay and straw to put over it. This was done on a wonderful earthenware support built on top of simple framing to elevate the oven to allow for the rocket stove underneath.

Larry Winiarski offered suggestions and tweaks to improved the efficiency of the stove, and Flip and Jon report that it makes a beautiful pan of rolls and marionberry pie, with very little wood, and can also boil water off the top of the chimney. Nicely done.

Kobus Venter put together a great article that helps define the Rocket Stove. Please take a look at it on his web site: http://vuthisa.com/2011/03/21/what-is-a-rocket-stove/

The "Easy 5 Gallon Bucket Rocket Stove", is very easy to build. All materials anyone needs to cook a good hot meal is a metal 5 gallon bucket, some stove pipe and vermiculite, pearlite or similar insulation (even "wood ash" can be used). Since the insulation separates the heat from the housing, almost ALL of the flame and heat is directed up to the cooking pot or utensil. Almost NO heat is wasted, making it one of the most efficient rocket stoves I've seen. Definitely one one the EASIEST to build and transport!

One fine rainy morning two fine fellows from StrawJet (http://www.strawjet.com) , an Oregon company that makes equipment to bundle agricultural waste in Malawi, wandered into the lab and asked if it’s
possible to make a stove that uses bundled corn stalks to cook food. I said that I thought it was possible and after some conversation and testing of prototypes StrawJet put up a $250 prize to encourage Stove Camp participants to make it so.

Burning corn stalks leaves quite a bit of ash that does not fall apart but keeps its shape.
For this reason stoves must be adapted to deal with a lot of solid ash. Two types of stoves
were tested: 1.) A Jon Anderson Rocket Stove with lots of draft and a grate and 2.) Two
large TLUDs built by Paul Anderson and Art Donnelley that were vertically loaded.


Participants voted for the best stove that, in their opinion, was most effective. Jon
Anderson won the 2010 Cat Piss Award for a tall Rocket stove made entirely from found
materials that successfully burned the bundled corn stalks. The hope is that a pilot test
could be conducted in Malawi. If so, we’ll pass along the results.

Jon and his wife Flip have been in Haiti recently for three months helping folks to build
these kinds of Rocket stoves. They are beautiful, dedicated people, who like many folk at
Stove Camp, deserve real praise and adoration. I’m happy to send them some of both and
congratulations for making a wonderful stove!

Fuel, Stoves and Water for Haiti
January 27, 2009

There are several projects to supply fuel, stoves and potable water to Haiti. Some have been been ongoing since before the quake and some. The organizations we know of are:

CHF International, Helps (Water Purifier)
To donate a $35 water purifying system, go to https://secure.helpsintl.org/store/haiti.php

Legacy Foundation (Fuel Briquettes)

Miombo, Project Haiti www.prohaiti.org
Peko Pe TLUD pellet fueled stoves to be distributed by Project Haiti. Pellets from Georgia.

Trees, Water, People TWP
Ananda Marga Universal Relief Team AMURT http://www.amurthaiti.org/ and
Recho Rocket stove made from mud formed in a bucket, the Haiti Rocket Stove
Stovetec Rocket Stoves in a metal bucket.

World Stove, International Lifeline Fund
Biucci, Everything Nice TLUD stoves fabricated in Haiti. Pellet fuel from Florida (Green Circle). Grass pellets to be made in Haiti.

Summary of Aprovecho’s Summer Stove Camp, 2006
By Dean Still and Nordica MacCarty, September 6, 2006

Aprovecho Camp 2006 02Aprovecho Camp 2006 02

Stove Camp 2006 was extremely interesting, especially because we had experts here who could help define what is known, figure out what needed to be done to expand the state of knowledge, and then, most importantly, have the tools to accomplish the experiments.

For Dean, the best moments happened around the table above when Chris Roden, Jonathan Lewis, the Aprovecho staff and everyone tried to get a general feeling for wood-burning stoves effect on global warming. Aprovecho’s recent tests at CSU of greenhouse gas emissions such as CO2, Methane, N2O, NOx, etc. helped to predict the gaseous emissions from the following stoves:
• Three stone fire
• Rocket stove
• Karve Gasifier stove
• Philips fan stove
• Charcoal Jiko stove
• Mayon rice hull burning stove

The gases, however, are only a part of the picture: particles also play an important role in the atmosphere. We learned that elemental (black) carbon particles produced in flames have a warming effect 1000 times greater than CO2 per gram, while organic carbon (white) particles produced by smoldering have a cooling effect 150-200 times stronger than CO2. Thankfully, Chris Roden had brought his and Dr. Tami Bond’s ARACHNE system which could measure the composition of the total PM to determine what percentage of black or white particles were produced by the stoves above. Chris, Damon and Nordica were at the lab till 11pm having a great time testing these stoves. Results should be available soon.

Doing this kind of research in a small lab in Creswell, Oregon for no money is what ETHOS stove camp is all about!

The publicized theme of this year’s camp was a competition to design the cleanest-burning fan stove. Two categories, side feed and top feed were awarded prizes. The top feed prize went to Dr. Paul van der Sluis for the Philips fan stove. The side feed Rocket stove with fan developed by Roger and Sule of Colorado State was the cleanest burning side feed stove. Congratulations to the winners!
