Subject: [ethos] Highlights from ETHOS 2007

 

All,

 

ETHOS 2007 in Seattle was a stimulating and inspiring event. Many thanks to
the ETHOS executive committe for organizing it and to the 120 attendees,
some who dragged stoves on airplanes to the event. There were many high
points during three (for some four) days of meetings which I am sure will be
discussed in these forums and on the web for weeks to come. To list a few:

 

Stove Demonstrations:

 

Paul Anderson's "Lily" alcohol burner and the Petrobryte alcohol lamp were
demonstrated and shown to be very clean burning.

The latest version of the Philips fan stove was demosntrated and lived up to
its promizes as being the cleanest burning wood burning stove.

Aprovecho demonstrated two of their institutional stoves and Alan Berick
showed off his energy efficient cooking pot.

Project Gaia demonstrated their Dometic alcohol twin burner.

The Anderson family demonstrated a selection of clean burning gasifier
stoves from a natural draft "Chipenergy grill" burning cherry pits and chips
to a small fan powered rice hull burning Juntos B and the Reed Woodgas stove
burning wood chips.

Crispin probed all the stoves with a portable combustion analyzer and
performance was discussed as stoves were stoked, adjusted and tuned.  

 

Stoves on Display:

 

We saw a real-life versions of Crispin's Maputo Clay Stove (MCS) for
charcoal, a Hot Pot (Solar Heat Energy) solar cooker, a Winiarski steam
boiler and engine and a selection of rocket stoves. Displays were enhanced
this year with video and computer animations.

 

UCODEA (Uganda) showed us a video of their production facilites and program
for wood (rocket) and improved charcoal stoves.

Ken Goyer had a running display of images from Uganda and AIDAfrica.  

 

Food, Agricultural and Soil improvement techniques related to household
energy:

 

Laurie Childers gave us a tour, history and update of reforestation, water
conservation and KCJ production in an area of Kenya including
water-conserving trees, sand dams, results of 23 years of tree planting. 

Dr. Karve displayed an interesting selection of ARTI technologies for plant
production and energy conservation including solar dryers, low cost
greenhouses and water tanks using bamboo, compact biogas, strip growing
crops with seawater, and feeding crops with sugar.

 

ETHOS Committee on Standards and Methods:

 

Tami Bond organized and led an extended discussion on the possible formation
and role of ETHOS technical committee(s) to develop, review, or adopt
methods, standards and practices for building or testing stoves. This has
started a process which should help promote understanding and definition of
how we build and test stoves for diverse environments. 

 

The technical committee discussion was partly prompted by a PCIA Stove
Performance Guidelines Meeting held Jan 25 to consider stove performance and
emission thresholds for stove selection to meet WHO standards. At that
meeting the water boiling test (WBT) as currently used was challenged as a
basis for measuring performance or emissions. An ETHOS Technical Committee
is a possible mechanism for resolving issues of this kind. 

 

Technical Program

 

The formal program was full of fascinating reports on stoves work. 

(See program http://www.bioenergylists.org/en/ethos2007program )

The presentations will be available on the ETHOS site within a few weeks.

Publications:

 

In the printed information for sale or circulation at the meeting were:  

An advance copy of the "Comparing Cookstoves" by Aprovecho for Shell
Foundiation and Partnership for Clean Indoor Air. 

"Place-Based Education Workship Guide" by HELPS International for
Partnership for Clean Indoor Air.

Video of Aprovecho's Rocket Institutional Stove.

"Forests Forever" Trees Water People Newsletter, Fall 2006, 

ETHOS 2006 conference proceedings,

and other organizational brochures and information. 

Links to these publications will be provided on the Biomass Cooking Stoves
website as they are made available.    

 

Thanks again to all for a productive and entertaining meeting.
