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.<br>
<br>
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.<br>

<div>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.</div>

[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.. <br>
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.<br>

I agree with Ron on several points:<br>
1. Almost no data.<br>
2. TLUD stoves have acceptance by users.<br>
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.<br>
<br>
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. <br>
<br>
Four exceptions:<br>
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.<br>
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.<br>
C. Some models of World Stoves by Nat Mulcahy make char,
but again data on acceptance is not released.<br>
<br>
[All three cases above are by for-profit businesses.]<br>
<br>
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.<br>
<br>
In summary, Ron's statement of his belief that :
<blockquote type="cite"><strong>char-making stoves win the
stove-acceptance battle hands-down </strong></blockquote>
remains to be proven or dis-proven.<br>
