[Stoves] Aprovecho Stove Camp

Thu Aug 1 04:39:10 CDT 2013

Hello Cecil,
Thank you for your excellent questions and comments.  I will answer you later today after I get some sleep.   It is only now –August 1 at 2:36 AM  in British Columbia, Canada – that I read your email.  I have been busy cleaning my house after a painting and drywalling job  during a 10 day absence;  and reviewing with my staff and potters in the Philippines possible changes to the Eco-kalan designs.  Regards,
Rebecca

Ditto the appreciation.  

Can you name, describe and link us to the rocket stove from the Philippines?  Is it the three component clay ECO-KALAN C stove that was recently introduced to the stove discussion group by Rebecca A Vermeer? 

If it is this stove, can someone explain to me how the cost to produce these three components comes - as reported by Rebecca - to $25?  How can the cost of production for a fired clay stove produced by local potters and ceramic workers in the Philippines possibly cost that much?  In Java I am sure the indigenous stove makers would be able to produce them for $2.50 to $3 each; the retail price would be perhaps $4 to $5.  

If the same ECO-KALAN C stove is on display at Stove Camp, then can somebody who is attending the camp find out how a ceramic stove that would probably retail for $4 to $5 in Indonesia (all costs in) can possibly cost a charitable stove agent in the Philippines $28 per stove to produce and bring to market??..I understand that Rebecca is including all the cost to her stove charity to produce, store, transport, distribute, promote, demonstrate and finally to market an improved stove. 

There must be well established traditional stoves on the markets in her area that sell for less than 500 pesos each ($11.50) and stove customers are simply not willing to spend an additional 700 pesos ($16) - which may take a low income household a month of scrimping to save - to purchase the higher performance ECO-KALAN C stove. In the end the battle to take and hold market share has to be fought and won in the local stove markets.  The benefits offered to a stove buyer's household have to be obvious to consumers who will not be willing to give up the familiar conveniences of their baseline stoves.  It will be dramatic reductions in fuel collected or purchased together with equally dramatic improvements in 

(i.)    speed of stove ignition and smoke production during start up, 
(ii.)   ability of a stove to burn damp or wet wood, 
(iii.)  the ability of a stove to combust multiple biomass fuels, 
(iv.)  the capacity to turn up a stove's power to accelerate the cooking process or to cook for special 
        occasions and the extended family, 
(v.)   the capacity of an improved stove to performs both household and home industry functions  with
        equal facility, 
(vi.)  little or no change required in stove operation techniques and knowledge to successfully cook on an 
        improved stove and to get full benefit of its higher performance, and
(vii.) the capacity of an improved stove to replicate all of the essential stove work functions traditionally
        performed by the dominant baseline stove(s) or by radically improving one or more specific stove
        work functions such as introducing a TLUD stove that cooks very clean thereby minimizing soot 
accumulation on pots and pans and n in a much cleaner kitchen possible,

e savings of money, time and effort to low income households at the Bottom of the Pyramid rather that 'saving' the lungs, eyes and health of stove users that will determine whether new stoves will gradually gain an increasing share of the 'traditional' stove market.

  List:

      This just a short summary of yesterday's first of five days at the Aprovecho Stove Camp.   This year, they are focusing on TLUDs.  About 50 people were at the opening session, with about 20 - 25 from the different parts of Aprovecho, and maybe 10 staying of those on as part of the camp.  
      The old timers here included
       a  Dean Still, who was the key organizer.  I was most amazed of everything here about how much Aprovecho has grown and changed over the 15 or so years I have known Dean  (who says he will retire in a year).
         1.   We go maybe today to a new factory for an off-shot firm called InStove  (Only institutional stoves  (like one 100 liters).  Damon Ogle is with them now. A first overseas factory coming soon.  Only Rocket principles here.
         2.  We will visit the factory where they are making the US StoveTec 
         3.  We will visit a new 5 acre campus about 6 miles away - a former high school where they will be moving to this year.
         4.   I heard a little about a new large research grant from DoE - one of four nationally,
         5.   There were staff people all over the place - maybe more than ten (?) not part of the camp.  
         6.   A key organizer who introduced Dean was Mark Hatfield.   
         7.  Owner of the Apro property was Fred Colgan - alo head of InStove
         8.  Larry Winiarski is a leader of one on 4-5 subgroups that formed.  Interestng oven design with a Rocket, built by a couple named Anderson.   Also a ceramic Rocket from  Philippines.
         9.  Dean is leading one of the 4-5 subgroups - which is mostly on TLUDs, but one large plancha design (18 by 24 inch - $22) plancha from Guatemala.   Much of yesterday  learning how to use test equipment

      b.  Paul Anderson, who brought 10 flat packs of a nice looking new TLUD design from Uganda, for on-site assembly.  
  Maybe 8-10 people in his subgoup.  Mostly will be doing testing here on (like all)
  Paul gave a nice one hour intro to TLUDS.  Both a son and grandson are here.

      c.  Art Donnelly at last minute decided to assemble one of his very large TLUD stoves from Costa Rica.  His primary air control from slight tilt using a wedge at the bottom.

  Of course many new-comers.   I ended up speaking most to three school teachers from D.C., hoping to establish a stove design challenge for 7th and 8th graders

  More coming.    Questions?      Ron
