Dear Leslie and all Stovers, especially those with interest in
char-making stoves,
(also being sent one time to the Biochar Listserv (yahoogroups) for
their comments also.)
Leslie raises a valid question:
Should the various issues about "making of char in cookstoves" be a
topic at the GACC Forum?
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.
And when that char will be burned in improved charcoal stoves, it
becomes doubly interesting for the stoves conference.
Mention can certainly be made that the produced char could also be used
as "biochar" (char destined put into soils).
Here I raise the questions:
Which of the biochar (BIOchar) aspects can or should be presented at the
Stoves Forum?
To what extent should they be emphasized?
And who will be in attendance at the Forum for such discussions?
__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.
Please speak up about "biochar as a topic at a stove Forum". And do
say if you plan to be there in mid March.

Colleagues -- the abstract submission process is currently open for
the Alliance Clean Cooking Forum in Cambodia. We have not finalized
the agenda by any means so please feel free to submit an application
on that the biochar subject where it will be considered with the other
submissions. We will also have open sessions each morning from 7-9 am
for groups to meet on whatever subject they choose as well as many
informal opportunities to share information on topics like biochar and
so I invite you to join us.
Regards,
Leslie
p.s. the travel scholarship application process is also open right
now. Please note you must be a member of the Alliance to apply.

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.

*[RWL4b': <snip> I just finished reading the thesis

*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.
