Christa Roth took these photos of Paal Wendelbo making a Peko Pe stove in the Aprovecho workshop during stove camp 2009. The stove, made from what was availble on site in about 2 hours, proved successful burning wood pellets and was awarded the prize for most interesting development.

Dean Still and Nordica MacCarty

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.

Stoves Camp 2009 Group Photo

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.
