[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>
