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 http://www.aprovecho.org/lab/index.php.

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.

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:
*An attached .pdf of the results and highlights of camp.
*All of the presentations and resources posted on our website at: http://www.aprovecho.org/web-content/publications/publications.html
*Many photos are also uploaded on picasa at http://picasaweb.google.com/aproresearch

Thanks for making Stove Camp 2008 a great success, and we hope to see you in the future!

With best wishes,

Introduction to Gold Standard/Carbon Credits

Gold Standard

There has been a lot of interest recently in carbon credit financing for improved stove projects. Since 2006, stove organizations have begun to receive funding from carbon credits. The Gold Standard has just published a set of protocols formalizing how stove projects can prove the lowering of emissions. Large financial institutions, like Climate Care/JP Morgan, are now participating in the relatively new market.

Summary of Aprovecho’s Summer Stove Camp, 2006

Aprovecho 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!
