<html><head><style type='text/css'>p { margin: 0; }</style></head><body><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>http://lists.bioenergylists.org/pipermail/stoves_lists.bioenergylists.org/attachments/20130122/a516d2d2/attachment.pdf<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>www.clean<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><br></div></body></html>
