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
