Good suggestion. If we can get Paul, Art and Nathan I'd be happy to moderate
the discussion.

How about World Stove users in Rwanda? I heard at least once they are
bringing in the char.

Paul,

Art Donnelly or someone from Seachar should be on the panel if he is not in
Costa Rica. Who else has worked in the field with biochar from stoves?

Do we have enough information, or field experience, to know whether biochar
from stoves has been adopted and used by cooks? Does the shoe fit? I suspect
that in getting used to a new stove, like a TLUD, it takes the cook awhile
to buy into it. Saving the charcoal is another step. Making biochar of
different qualities for different purposes would be another step. How does
using a biochar stove differ from using the fines from an earth kiln,
beehive kiln, Adam retort, Pronatura kiln or other charcoal making device
that might be is use nearby? 

If we have the cast these topics would be useful. 

Tom

Dear all,

I totally agree with the Tom and Mark about having a panel on biochar at the
ETHOS 2012 meeting at the end of this month (January).

I submit the following additional information:

1.  I offer to be on the panel.  I attend biochar conferences and frequently
present about biochar production.  I think that I should NOT organize nor
lead the panel.

2.  Let's define what biochar issues will be focal, and which will be
secondary.  Tom Miles wrote:
> I think the emphasis should be on field experiences with the use of

However, ETHOS is NOT a group of soil and plant scientists, nor is it
focused on climate change.  Summary statements about the secondary topics
could be useful.  But our primary focus actually is the ability of
cookstoves to make char (and what types of char?) and in what quantities and
with what fuel feedstocks.

3.  I am sbmitting today (via this message to Angie)  my abstract for a
presentation at ETHOS.  I would like this to be a regular presentation that
is at any time slot before the panel discussion.

Abstract for ETHOS 2012

Title:  Micro-gasification for Combined Heat and Biochar (CHAB) in "Mini"
Industries

Authors:   Paul S. Anderson, Charles Anglin, Art Donnelly and Paul W. Wever

Abstract:
Micro-gasification devices at "mini" sizes from 20 to 150 kW (70 K to
500 K BTU/hr) provide far more thermal power than is needed for
institutional cooking and far less than most applications of the heat for
small industry and space-heating of buildings.  Currently functional devices
and applications are explained and discussed with quantitative data.  These
include:  TLUD heat for Paramont Dairy in Uganda; TLUD drying of cacao beans
in the SeaChar project in Costa Rica; AVUD (continuous automated operation)
heat and biochar production for a municipal bio-digestor and for factory
space-heating by Chip Energy in the USA, and barrel-size biochar production
(without use of the heat) by several initiatives, including the Jolly Roger
Oven, the Re:Char project in Kenya, "in-field" biochar-barrel system by
Anderson, and efforts by UB International in Mongolia and elsewhere.

********************************
Notes:

1.  Anderson will be working with Art Donnelly in Costa Rica in the middle
half of this month, so the results presented will be as up to date as
possible.

2.  This presentation is intended to be one of several by different people
at ETHOS about TLUD micro-gasification.  Known or suspected presentations
include (These are NOT in order, and we hope that they will NOT be in
concurrent sessions,)

A.  Marc Pare, on micro-gasification advances using rice husks as fuel in
TLUDs.

B.  Christa Roth, on GIZ advances with charcoal stoves, including the  
TChar technology.   (if unfamiliar with "TChar", please see    
www.drtlud.com   )

C.  Paul Anderson, the CHAB devices (see abstract at start of this message).

D.  Robert Fairchild, (title not known, but he works with TLUD and TChar
devices for project in Haiti, and brings an engineering perspective to the
topic.)

E.  Kathy Nafie, President of the Biomass Energy Foundation, presenting
about outreach activities in North America and overseas by the BEF relating
to micro-gasification.

F.  Presenter unknown, but work by Aprovecho on TLUD / micro-gasification
will probably be presented (we hope).

G.  Does Jim Jetter or someone else involved with stove testing have a
summary of emissions data from micro-gasifiers?  (we hope so.)

H.  OTHERS:  I do not want to leave anyone out, but I do not know of all of
the efforts with micro-gasification, and / or if they will be attending.
There are now numerous projects and efforts around the world (including
Wendelbo / Formo in Zambia).

And because all of the TLUD stoves and devices can be use to make biochar,
these also relate to the topic of this email.  I would like to hear (via a
direct message) from anyone with a TLUD-type topic for presentation, even if
you are not going to attend ETHOS.

NOTE:  The deadline for abstracts to ETHOS is TODAY 1 January 2012.   
In past years there have been some extentions of time, but that is up to
Angie and Mark of ETHOS.  Contact them immediately if considering sending in
an abstract.

Plus:
The Saturday evening presentation (sometimes called a "Keynote"  
presentation) this year will be on

"The Present and Future of Micro-gasification for Cookstoves:   
Expectations for Achieving the 2020 Goals of the Global Alliance for Clean
Cookstoves."

I will be making that presentation, and I assure you that it will NOT be
what you have heard before nor even in the numerous presentations listed
above.

I am suggesting that the ETHOS administration allow this to be a "public
lecture" open to everyone, not just to the those who register for the ETHOS
conference.  If that is allowed, we can attract a larger audience to our
ETHOS objectives.  Perhaps our host University and other organizations such
as SeaChar and BEF could help publicize the presentation.
