<div class="moz-cite-prefix">Dear Leslie and all Stovers, especially
those with interest in char-making stoves,<br>
<br>
(also being sent one time to the Biochar Listserv (yahoogroups)
for their comments also.)<br>
<br>
Leslie raises a valid question: <br>
<br>
Should the various issues about "making of char in cookstoves" be
a topic at the GACC Forum? <br>
<br>
For THAT I can fully agree with. One or two presentations, or
maybe an open session. That aspect of the session/presentation
would be a natural fit with discussions of TLUD gasifiers and any
other devices that can intentionally produce char.<br>
<br>
And when that char will be burned in improved charcoal stoves, it
becomes doubly interesting for the stoves conference.<br>
<br>
Mention can certainly be made that the produced char could also be
used as "biochar" (char destined put into soils). <br>
<br>
Here I raise the questions: <br>
Which of the biochar (BIOchar) aspects can or should be presented
at the Stoves Forum?<br>
<br>
To what extent should they be emphasized?<br>
<br>
And who will be in attendance at the Forum for such discussions?<br>
<br>
__I__ intend to be at the Forum and will be speaking (if selected
to be a presenter) about TLUD stoves that "make charcoal that can
be burned or used as biochar". My current thinking is that I
will request to present about the latest developments of the TChar
variation of TLUD stoves, and in those stoves the charcoal is
consumed by burning. I will mention the biochar prospects and
can answer questions that could arise about biochar, but there
will not be more than a minute of two for BIOchar comments. <br>
<br>
Please speak up about "biochar as a topic at a stove Forum". And
do say if you plan to be there in mid March.<br>
<br>

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>

[RWL4b': <snip> I just

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.</span></strong></span></b><span

<p class="MsoNormal">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 : <o:p></o:p></p>
<p class="MsoNormal"><strong>char-making stoves win the
stove-acceptance battle hands-down
</strong><o:p></o:p></p>
<p class="MsoNormal">remains to be proven or dis-proven.<br>
