Bundled Corn Stalk Stoves for Malawi, Stoves Camp 2010

24 August 2010 - 2:36pm

Dean Still, August 2010

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!

Stoves Camp 2010 Charcoal Stoves for Haiti

24 August 2010 - 2:01pm

Stoves Camp 2010, Cottage Grove Oregon

Stoves Camp Participants

Fifty two high energy participants attended Stove Camp this year at Colgan’s Island, camping near the river, making and testing stoves, and listening to Fred’s Big Band harmonize so beautifully. Fred and his volunteers cooked breakfast every morning and dinners at nighttime parties on Rocket and TLUD institutional stoves.

Nick Salmons from International Lifeline Fund made a very successful Haitian charcoal stove that was voted “Best in Class” by his peers!

Stove Camp provides a venue for a gathered scientific community to advance knowledge of biomass cook stoves. Participants made new stoves and tested them daily for fuel use and emissions. Every morning the test data was shared and new stoves were constructed.

This year, a great deal of progress was made on charcoal stoves for Haiti. Camp participants, some of whom have worked in Haiti,designed a two-hour Water Boiling Test for Haiti, which uses a Haiti pot
and mimics a typical cooking task, cooking rice and beans. Charcoal stoves were constructed that used less fuel and produced less carbon monoxide compared to traditional Haitian stoves.

See the attached Stoves Camp Report for details of the tests, the interesting findings about the optimum charcoal to use for each stove, and pictures of the stoves tested.

Testing of the Anila stove in India August 2010

22 August 2010 - 2:24am

The aim of this test was to finalise the design of the Anila stove, which had been produced in India ready for distribution to households to gather feedback from them about usability.
This is for the project:

Without wanting to change the design too much from the original plans, the following changes were deemed necessary –

Mali Sewa Stove Update

9 August 2010 - 4:32pm

Katene Kadji, is now manufacturing the Sewa Stove in Bamako, Mali.

The new Sewa Improved Charcoal Stove has a ceramic liner, and a painted metal exterior, with jiko style pot rests that put the bottom of the pot low enough to improve heat transfer to the tobt

The carbon finance company E+Carbon is using carbon credits to help Katene Kadji to be able to offer the stoves for 2,500 CFA francs (5.33 USD) as opposed to the original retail price of 3,500 CFA (7.47 USD).

There is a current case study of the Sewa Stove at the Gold Standard web site:

Testing of the Sampanda stove in Cambodia 12.07.2010
Sarah Carter, UK Biochar Research Centre

See http://www.bioenergylists.org/content/testing-andersons-tl for a similar test on Anderson's TLUD, and http://www.bioenergylists.org/content/testing-everythingni for testing of EverythingNice stove, and Anila stove http://www.bioenergylists.org/content/testing-anila-stove.

Stove: Sampanda stove. Produced by the [Samuchit Enviro Tech Pvt Ltd](http://www.samuchit.com/) in India.
Test: A water boiling test (time to boil 2.5 litres of water, in a pan without a lid)
Location: The Iron Workshop, Siem Reap. A well ventilated building – 2 surrounding walls, and a roof. Wind conditions were low, but blustery at times.

Proyecto Estufa Finca An Update from Seattle

Art Donnelly, SeaChar.Org June, 2010

It was not quite 9 months ago, when I sent out an email to a small group of collaborators, with a Subject line that asked the question: "How do we get biochar stoves to Central America?" Of course, like the punch line to the old vaudeville joke, the answer is "lots of hard work". I could not have imagined 9 months ago was how rewarding all that work would feel. I want to share that feeling with all of you.

I recently returned to Seattle from Costa Rica's famed coffee producing area the Santos Zone. This was my second trip since mid- January. I have been continuing my work as a technical consultant to a clean stove/biochar project. Proyecto Estufa Finca (Farm Stove) was initiated by organic coffee farmer Arturo Segura http://www.solcolibri.com/ and the members of the local citizens group APORTES.

The Peacham iCan TLUD Stove

Gill

Jock Gill, May 2010

With one can: I can make a stove I can cook a meal I can make biochar I can be carbon negative I can start to change the world

This iCan is made from a 7" tall pineapple juice can

I took a 7" tall pineapple juice can, removed the contents, and then marked it thusly:

1. A line around the can 1/3 from the bottom --- this is the top of the fuel load

2. A line around the can 1/3 from the top -- this is the line for the secondary air holes

The middle section is for the wood gas buffer to insure pyrolysis, not combustion.

Primary air supply for a 7" tall pineapple juice can

Marked the bottom of the can off into 8 equal sections. I then used a nail set to make 8 equally spaced holes about half way between the outside of the can and its center. I made a 9th hole in the center. Not too big -- about 1/2 way down the small nail set shaft.

Then I used the line1/3 down from the top to locate the secondary air holes.
I made 8 equally spaced holes with the small nail punch and then used the the biggest punch to enlarge the holes to the full width of its shaft.

At this point I removed the top of the can completely. I left it on for the best structural integrity while I was punching holes.

Done. The All-in-One TLUD is complete. Very simple. Just 17 holes in the right places in one can.

World Stoves work in Haiti covered in the press

Mulcahy

Nathaniel Mulcahy May, 2010

Nat Mulcahy and the World Stove Haiti project was nicely profiled on the web site The Charcoal Project. Read the full article A Man, a Stove, a Mission

From the Charcoal Project article:
"Mulcahy is the founder of WorldStove, a small Italy and U.S.-based company that manufactures a range of energy efficient, biomass-burning cookstoves. The company operates two business lines. One sells pricey cookstoves and barbeque grills for the outdoor/camping crowd in industrialized societies. The other line of stoves, the research of which is funded by the former, helps bring energy efficient cookstoves and locally owned businesses that produce them, to the oceans of energy poor people around the world who don’t have access to modern fuels like LPG and electricity.

"Mulcahy has recently returned from Haiti where he spent two months setting the foundations for a sustained long-term plan to alleviate the country’s heavy dependence on the inefficient combustion of the wood and charcoal. President Bill Clinton, the UN Special Envoy to Haiti, highlighted WorldStove’s remarkable and quick work in Haiti in a recent Earth Day address."

The World Stove has also been profiled (by Kelpie Wilson) on the Huffington Post, read WorldStove: Transforming Haiti and the World

And there are some great videos on YouTube, including this one:
