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.

What is an Improved Cook Stove?

Aprovecho Stove Camp 2007 UPDATE: 6-12-2007
Jeremy Roth, Aprovecho Research Center, June 12, 2007

The 2007 Aprovecho Stove Camp is almost 1 month away! We have reserved a group campsite at Dorena Lake (where Dean keeps his sailboat) just outside of Cottage Grove. If you plan on attending Stove Camp, and would like to stay at the campsite (cheaper than a hotel, and much more scenic), please contact Jeremy at Aprovecho to reserve a spot. Total cost per person is $40 for 5 nights. We have the site reserved from 7-15 through 7-19. There are also hotels in Cottage Grove and Creswell for approx. $60 - $100 /night.

Cost for the Stove Camp is $100 for students. $200-$500 for others (Sliding Scale)
Please contact us to sign up!

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!

Laboratory Testing of Rocket Stoves of Various Capacities As Compared to the Three Stone Fire
Dean Still, Nordica MacCarty, Aprovecho Research Center, April 2007

In an effort to understand the relationship between stove capacity and fuel use and emissions the performance of three sizes of rocket stoves were compared.


The stoves were tested with the 2003 UCB revised Water Boiling Test. Pots that were integral to the stoves were used without a lid. Kiln dried Douglas fir at approximately 10% moisture content was burned in all tests. Only one test was performed on the household stoves. Therefore, results are not statistically valid but should be useful for general comparison. The [attached] graphs show results from three Rocket type stoves as compared to a carefully tended Three Stone Fire.

As seen at ETHOS 2007, we have put together a step be step video on how to build Damon Ogle's design of an Institutional Barrel Stove. The stove is constructed from 200L barrels.

The stove was able to bring 45L of water to boil in 37 minutes using only 2150g of wood.

In a Controlled Cooking Test the Institutional Barrel Stove used 73% less fuel than an open fire!!

The video is available in multiple part downloads here on our website

The video is also available on DVD for $10 + Shipping.

Rocket Stove Questions and Answers: Rocket Stove Air Supply - Primary and Secondary Air

Dear Stovers,
The fuel magazine that sticks out the side of a rocket stove is divided into two: above the shelf is where the fuel goes, and air passes under the shelf. Am I right in thinking that the fuel should be packed in as much as possible, to try and minimise the amount of air entering the stove through the fuel inlet? If so, why? My experience is that char builds up at the bottom of the elbow, so air is needed to burn the char (which in turn pyrolises the fuel), and a second air supply is required to burn the volatile gases. Any pointers would be warmly received.
Confused, Hugh.
