Ron,
Thanks for the report.
I would be interested in reading your presentation, "Specifying Stove
Performance in Climate Terms".
Interesting to read about the "emphasis on China" that Dean refers to...
and that ~1800 or so Stove manufacturers in China might be making
"gasifiers"... that could also possibly be producing Biochar.

Two Lists (cc 4 who read both lists; two of whom have promised to
add and hope other 2 will also, as well as any/every one else who
cares to - especially not limiting their scope in any way.)
1. This summary is intended to only cover topics that might be of
interest to both the above lists. Emphasis only here on what most
interested me. What are not covered in detail are things like rocket
stoves, details on stove testing, work of the GACC not pertaining to
biochar, etc.
2. To understand the following, you will have to have a copy of
the session schedules - as sent around by the Conference chair Prof.
Ken (Mark) Bryden - and can be found at
http://lists.bioenergylists.org/pipermail/stoves_lists.bioenergylists.org/attachments/20130122/a516d2d2/attachment.pdf
To shorten this writeup, I have given numbers to the time slots,
so that Sat AM and PM are 1A and 1P. Sunday same as 2. Then within
the A's and B. I add another few numbers. For instance I really liked
a modeling talk by Nordica MacCarty, now a PhD student with Mark. Her
session would be labeled as 1A51-2 - The Monday AM, fifth time slot
in Room 1 (there were 3) and she gave the 2nd talk. Just to finish
up with her contribution as it applies to char-making stoves, I
believe that her thesis is maybe quite complete, but not available for
some months. It will give good design data for best pot sizes, flame
path dimensions, skirt dimensions - and many topics that are
transferable between rocket and char-making stoves. I raise this
first to ask if anyone knows of modeling programs that cover
char-making stoves? Nordica's program covers 16 specifiable
dimensions/parameters - and then calculates interior temperatures and
pressures using standard engineering equations and all the important
flow numbers that you can imagine.
3. Before going through the full agenda, my overall impressions
(have been to 5-6 of these including last year):
a. Big positive changes in almost everything related to
low-cost wood/pellet burning cook stoves - all due to the growing
funding importance and influence of GACC
Seewww.clean*cookstoves*.org/
Maybe a staff of 20?? (at least 15?)
b. A session on carbon credits. Bad now but I think 50 stove
programs getting carbon credits now.
c. Many from other countries this time - because GACC is
finding 12 regional stove testing centers (meeting also this week in
North Carolina with Jim Jetter as a trainer)
d. The older stove companies are all doing quite well (Maybe
10 from Approvecho, 3-4 from CSU, half dozen (?) from Burn Design Lab
(who are signing big deal with GE this week)
e. The role of char-making stoves and biochar hasn't changed
that much in a year - but some progress in understanding. I saw
little emphasis at GACC on TLUDs as being special. They are
supporting char-using stove improvements.
(There were at least 4 people from Solar Cookers International -
that technology being covered by GACC, but nothing special happening,
I think.)
f. I think attendance was up a little to 140 over previous
120 level. For those there at earlier times, I saw no changes of any
kind in format.
4. Now by time slot, startng with 1A
a. Two excellent talks by Ranyee Chiang (new to the
conference) on the plans and goals of GACC. This group has I think
excellent home in the UN Foundation - must be a big plus in raising
funds and getting the attention of appropriate governements. Now have
six early government partners. See above website. Nothing really to
report yet I think.
b. Good background talks by previous attendees Katie Gross
(phaseout of PCIA) and John Michell (EPA - DC) on the development of
an ISO standards program. Some discussion on Water Boiling tests.
c. Nine talks in three rooms. have already mentioned that by
Nordica. Other two from CSU and Aprovecho (Dean)
5. Time Period 1P
a. 1P1 Really good panel of five on carbon credits.
b. 1P2 - again multiple talks (7 here). I went to nice talk
by Dale Andreatta who has some of the best theoretical and
experimental data on small stoves then switched to a panel in
different room on WBT with three actively involved. Much done by Ryan
Thompson, having left Aprovecho to work with Prof Tami Bond at Illinois
c. 1P3 - Small group (10?) heard Tom, Paul and I talk about
biochar. Tried to put emphasis on stoves, but wide ranging
d. 1P4 - good after dinner discussion of black carbon by
Prof. Bond - a leader in recently released major study. She felt it
could be used to support stove development, but the technology really
looking bad are kerosene lanterns.
6. Time period 2A
a. 2A1 Dean Still led panel of 5 on how the GACC goal of 100
million clean stoves might be accomplished by 2020. He put most
emphasis on China - can do it alone, if they take it seriously. Three
Chinese there. One said that about 2/3 of the 2800 (?) stove
manufacturers in China are pursuing "gassfiers". To me this was one of
the major pieces of news - boding well for some must be top lit and
making char. General agreement that too little is known of China's
stove program details.
2. 2A2 6 talks in three tracks. I went to Room 2 to hear Jim
Jetter (EPA update) and then Ranyee Chang and Michael Johnson
(Berrkeley group) mostly on stove reporting - both WBT and health.
3. Time period 2P
a. .2P1 Panel of 3 - mostly on other RE in village settings
b. 2P2 Again 9 talks. I was first giving talk "Specifying
Stove Performance in Climate Terms". Glad to send PPt to anyone
writing me (off-list). I think I showed that the present approach in
the efficiency computations considerably undervalues the value of the
produced char.
Second talk by a woman from the Philippines with larger wood
burners (not on printed agenda) somewhat based on rocket principals -
all clay.
Third talk by Prof. Harold Annegarn of South Africa -
coauthored with Crispin P-P. Urging a standard vocabulary for GACC use
c. Chloe Shields on how information will be transmitted
through GACC
d. Stove demos - Paul A. was one demonstrating and hope he
can add. I had to leave for airport.
Hope others will add.
