Stephen,
Excellent. Please note: There is a major GACC stove meeting in
Cambodia in March 2013. Not much there about biochar, so it is
unlikely that you will attend. But I will be there and I (and others)
would like to have your data / results about acceptance of "stoves that
make biochar" (probably aka TLUDs ). Please make every effort to make
the results available in time.
If you need a person for discussions without using list serves (such as
for commenting on drafts on a confidential basis), I volunteer or could
help you find others.

Hi Guys
Very positive acceptance of the PED biochar stove in Northern Vietnam.
Initial results to be published next year and a short article soon
when I manage to get time to write it.
Regards
Stephen Joseph

*[RWL4b': <snip> I just finished reading the thesis by
Robert Pendleton Taylor recommended by Jim Jetter yesterday. He
has 6-7 different ways to subdivide the stoves universe and none
are by char character..
However, the issue of how to handle char permeates that
thesis - and I think appropriately. The char issue raised by Dr.
Taylor revolves around "batch" stoves - which is a pretty close
match to your "climate change" stoves. I need to emphasize that
primary emphasis has to be on the "cooking/heating" (not on the
char) - or no one will use a char-making stove. I think
char-making stoves win the stove-acceptance battle hands-down -
but there is almost no data to prove that.

I agree with Ron on several points:
1. Almost no data.
2. TLUD stoves have acceptance by users.
3. That Ron and I are biased [but correct!!] in our favorable
opinions about char-making stoves. But we also have some of the
longest times working with them. Ron started in the 1990s and me
in 2001, both with Tom Reed.
The lack of data on stove acceptance of TLUD stoves is largely
because of so little offer of them to users. And almost never
have they been offered side by side with other types of stoves.
Four exceptions:
A. The Oorja TLUD-FA (fan assisted) did 400,000 units in India
with BP funding. And that stove (with some style updates, etc)
is still on the market by First Energy. Clearly somebody liked it
enough to use it. However, the Oorja is not designed to make
char. So set that case aside.
B. Philips is getting into the gasifier stove scene. Unlikely
that they are doing it without some data on acceptance by users.
But no data from them.
C. Some models of World Stoves by Nat Mulcahy make char, but
again data on acceptance is not released.
[All three cases above are by for-profit businesses.]
D. The recently complete (Sept 2012, with Final Report still in
Draft form) Mwoto TLUD-ND (natural draft) by the World Bank BEIA
project in Uganda found that acceptance of that TLUD exceeded the
ability of the tinsmiths to produce units. That shows some very
favorable acceptance. As a result of that project, at least
three private companies have been created (Mwoto Factories, Awamu
Biomass Energy, and Pamoja - Uganda) and some independent
tinsmiths are continuing to make TLUD-ND gasifier stoves in
Uganda. These are start-up operations with minimal funding, but
they are progressing and certainly have a positive attitude about
user acceptance.
In summary, Ron's statement of his belief that :
*char-making stoves win the stove-acceptance battle hands-down *
remains to be proven or dis-proven.
