Stove Camp

Aprovecho Stove Camp, April 2-5th, 2012

From Mike Hatfield:

Attached is a flyer for the week and here are some logistics for those interested.


I will send out an updated agenda but a tentative agenda is as follows:

Stove Camp 2012

Day 1

Stoves Camp 2010, Cottage Grove Oregon

Stoves Camp ParticipantsStoves 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.

Forty three folks attended Stove Camp this year coming from as far away as Norway, Germany, Honduras, and Mexico. Some people were too busy making stoves to be in the official photo. Paal Wendelbo, winner of the $250 prize for most interesting development, is the white haired gentleman two spaces to Dean’s left. The theme this year constellated around health issues. You can see the presentations and results from Stove Camp by visiting

Stove Camp featured many experiments. We set up a Test Kitchen, in which stoves were tested, making posho (African corn meal mush). Particulate Matter and Carbon monoxide were recorded in both the room air and at the nose/mouth of the cook. We also used a RAD 57 from Masimo to non-invasively measure levels of CO in the cook’s blood before and after cooking. Stoves were also tested under the emissions hood, and practice WBTs were run without emissions measurements. Peter Scott and Dr. Andreatta were successful in creating an aluminum mitad with even temperatures for making injira.

Fuel Briquette Burning at Stoves Camp 2008

This prototype was to check the hole of the briquette and how gasification can do a nice job. As said, starting the fire with few small sticks and then after preheating the chamber, briquettes ignite by themselves and burn throughly. You can help flames with having a stick in the hole while burning. I really liked how the briquette retained its shape after it burned out, so you could still push the next one it without preventing the draft..

But the briquette burned with the surface lit from the combustion chamber, as Larry predicted. You could literally walk away of the stove with the consistent flame going on all the time (I guess the briquettes were good quality :) The air inflow was only through the hole of the briquette.

Funny was, that even when one briquette burned out, the next one ignited and the airflow continued through the hole of the first briquette.

Greetings Stove Campers!

I hope you are all well, back in your corners of the world.

At long last, the summary and data from stove camp is available, including:

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

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!

Dear All,

Stove Camp this year will take place August 4-8 here at the new lab which is on 4 beautiful acres with a nice river on two sides of the property. Folks are invited to camp here near the river! We will cook on wood burning stoves for lunch and dinner and bake tasty bread in a Rocket bread oven. We can have bonfires at night and figure out how to distribute one billion stoves.

Paul Van der Sluis from Philips may be able to attend. Friends in India are trying to buy and send us a BP stove. Can anyone in India assist them? I'll pay costs, shipping, etc.

Pam Baldinger, now in Darfur with USAID, very much supports this year's theme and contest. The team that cooks corn flour using the least fuel, etc. wins the more and more coveted Dr. Kirk Smith Cat Pee Award and $250! The most effective solutions will be sent to Pam.

Let's prove that cooking with wood can be done with very little fuel! It's important! Let's help refugees.

There's room for 25 participants. Book early!

ETHOS Stove Camp costs are:
Instruction/Participation: $100 students $200 others
Camping (5 nights): $25 students $50 others
Five dinners cooked here with wood on Rocket and other stoves: $25

Aprovecho Stove Camp 2007 SCHEDULE
Jeremy Roth, Aprovecho Research Center, July 12, 2007

Stove Camp 2007 is set to start on Monday 7-16 at 9:00 am. If you are planning on attending and haven't contacted us yet, please get in touch ASAP!!

The following is a schedule for the classes that will be offered for during the 2007 Aprovecho Research Center / ETHOS Stove Camp.

Aprovecho / ETHOS Stove Camp 2007- Creswell, Oregon
Jeremy Roth, Aprovecho Research Center, April 26, 2007

Once again, the annual Aprovecho Stove Camp will be held July 16-20 at the Aprovecho Research Center lab in Creswell, Oregon. Click here for a map

More information on the Aprovecho Stove Camp can be found on their website.

The Aprovecho Stove Camp is a chance for people interested and involved in the research, design, construction, and dissemination of biomass cooking stoves to come together for a hands on collaborative event. Participants will discuss, design, build, and test cook stoves in Aprovecho's laboratory. Sessions for newcomers and stove veterans will run concurrently.

Nordica MacCarty will do a training on how to use the Portable Emissions Monitoring System (PEMS) at Stove Camp July 16-20. We can evaluate emissions using the PEMS.

Paul Anderson will teach a session on TLUD (Top Lit Updraft) stoves.

We are awarding a $250 prize to the best natural draft stove...and doing a very thorough two day review called" Almost Everything About Stoves" that will run concurrently as folks build and test best stoves. (Two tracks happening at the same time). Tami Bond will probably be there and Dale Andreatta along with many other notables. Aprovecho has THREE COOL NEW STOVES to share.

COME ONE, COME ALL! Directions, etc. to follow!! Sailing on the lake, too!
