[Stoves] Report #1 from ETHOS meeting

Mon Jan 26 13:28:32 CST 2015

Hi Crispin and all, 

One of the groups of talks that I very much enjoyed were not on the official schedule, and they were a very thoughtful series of critiques of the current WBT, CCT and KPT tests by Nelson from CREEC and also Sam from Aprovecho.  It was encouraging to see the thoughtful engagement of both the strengths and the limitations of the tests, and that they'd very much like the conversation about the limits and conditions of the test to be included along with the results.  

I need to sit down and write up my impressions. It was wonderful to see people - and it was nice to see some great information about stove use and adoption along with the technical conversations about reducing particulates.

Dear Bodie

Please take these performance numbers with a grain of salt. 

Three of the metrics have no physical basis in reality and several of the others are misleading. ‎ For the char making TLUD's the 'fuel consumption' metric is highly misleading to the tune of >200%.  

Marc Park pointed out at ETHOS that in a village studied where all users had an 'improved stove and used them religiously' there was no net fuel saving. 

Before using a performance metric for comparison check first if it is telling you what you think it is (or have been told it is).  

Frankly, we don't really know how improved stoves compare in performance, for the most part. The ISO and the South-South Sustainable Stoves Group are both working on cleaning up this situation because it is wasting a lot of time, social capital and money.

Regards 

Crispin 

Wow! This is a great resource, Christa!  

I'm really curious about the StoveTec TLUD -- does anyone know why it had/has such incredible performance? And why is it not in production now (as the document says)? I would love to know more about it.

Thanks!

Bodie

Where is Christa’s “Microgasifier” compendium downloadable from?

List:

    A pretty good crowd (two, three dozen to start, and doubling [?] by end) for the Stove 101 learners session from 4-6.  Christa Roth, Dean Still, and Dale Andreatta all did great jobs.  Roth used parts a new more polished version of her “Microgasifier” compendium  (downloadable; highly recommended).  Dean showed 3-4 brand new stoves that are just beginning to be field tested (all types, not only rockets).  Dale gave overview of terms, especially testing.

    Buffet dinner (paid for I think by Aprovecho) until 7.

    Slide shows and some videos until maybe 9 - with the crowd continually growing  (maybe up to 2/3 of registrants?).  

Speakers were 
    Dale A. (on Sanitation) 
    Christa R. on some of her work in Africa 
    Christa has been working with a Senegalese  [maybe an engineer - Andre] who gave a full Ppt (partly in French) on their work - largely on charcoal using and microgasifier stoves); 
    Paul Anderson (short - on Gary Larson stove cartoon);  
    Sebastian Africano of Trees, Water & People - on their activities - mostly in Central America; 
    Adrian Padt of Durban, SA.  A clever Rocket design that can be shipped flat (stamped stalnless;  about 5000 sold in 2013, ten times as many last year); 
    Jon Anderson introduced video from Rebecca Vermeer of Phillipines and then his and wife Flip’s work on ceramic ovens.
    Gregory Egan on products with charcoal from Bamboo

Apologies for brevity and any errors.  Meeting off to a good start.  Seen lots of friends and many not yet seen.

Ron
