Thanks for the report.<br>
<br>
I would be interested in reading your presentation, "Specifying
Stove Performance in Climate Terms".<br>
<br>
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.<br>
<br>

<div style="font-family: Arial; font-size: 12pt; color: #000000">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.)<br>
<br>
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.<br>
<br>
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<br>
<a class="moz-txt-link-freetext" href="http://lists.bioenergylists.org/pipermail/stoves_lists.bioenergylists.org/attachments/20130122/a516d2d2/attachment.pdf">http://lists.bioenergylists.org/pipermail/stoves_lists.bioenergylists.org/attachments/20130122/a516d2d2/attachment.pdf</a><br>
<br>
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. <cite></cite><br>
<br>
3. Before going through the full agenda, my overall
impressions (have been to 5-6 of these including last year):<br>
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<br>
Se<cite>e</cite><cite></cite> <cite><a class="moz-txt-link-abbreviated" href="http://www.clean">www.clean</a><b>cookstoves</b>.org/</cite><br>
Maybe a staff of 20?? (at least 15?)<br>
b. A session on carbon credits. Bad now but I think 50
stove programs getting carbon credits now.<br>
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)<br>
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)<br>
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.<br>
(There were at least 4 people from Solar Cookers
International - that technology being covered by GACC, but
nothing special happening, I think.)<br>
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.<br>
<br>
4. Now by time slot, startng with 1A<br>
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.<br>
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.<br>
c. Nine talks in three rooms. have already mentioned
that by Nordica. Other two from CSU and Aprovecho (Dean)<br>
<br>
5. Time Period 1P<br>
a. 1P1 Really good panel of five on carbon credits.<br>
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<br>
c. 1P3 - Small group (10?) heard Tom, Paul and I talk
about biochar. Tried to put emphasis on stoves, but wide
ranging<br>
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.<br>
<br>
6. Time period 2A<br>
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.<br>
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.<br>
<br>
3. Time period 2P<br>
a. .2P1 Panel of 3 - mostly on other RE in village
settings<br>
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. <br>
Second talk by a woman from the Philippines with larger
wood burners (not on printed agenda) somewhat based on rocket
principals - all clay.<br>
Third talk by Prof. Harold Annegarn of South Africa -
coauthored with Crispin P-P. Urging a standard vocabulary for
GACC use<br>
c. Chloe Shields on how information will be transmitted
through GACC<br>
d. Stove demos - Paul A. was one demonstrating and
hope he can add. I had to leave for airport.<br>
<br>
Hope others will add.<br>
