Dear colleagues,
I hope this video finds you well. Our very own Mwoto stove featured at one of
the TED talks recently.

Enjoy it and kindly share it within our stove world.
Kind regards
Emmanuel

Subject: RE: [Stoves] "stove-acceptance" of char-making [TLUD] stoves.
Dear stovers,
I very much agree with Paul.
Oorja and First Energy in India are on the move and also, Phillips, with their
fan driven stove, to be made in Lesotho, are also moving quicly forward.
What`s surprise me most, is that Phillips, as a strong hold supplier, seems to
"overlook" the importance of tests from these types of fan driven stoves,
thinking mainly about emmissions.
These types of stoves consume the char and can not be considered as biochar
stoves, like Paul said.
On the other hand, why dont they also promote and introduce their own, natural
draft gasifier, to the rural areas?
Several pilots should be set up for testing of acceptance and proper use,
including different types of biomass as fuel, haveing in mind both household
energy and bio-char production.
We would be very much interessted to coorperate with Phillips on that issue, to
promote and test out the natural daft gasifier for the rural areas, linked to
both household energy and biochar, refering to the pilot on "Biochar in
conservation farming" - Biochar production using the gasifierstove Peko Pe
(TLUD ND) in Zambia 2011.
Have a nice weekend.
Greetings from DAR, TZ.

Subject: [Stoves] "stove-acceptance" of char-making [TLUD] stoves.
Dear Stovers,

[RWL4b': <snip> I just finished reading the thesis by Robert
Pendleton Taylor recommended by Jim Jetter yesterday. He has 6-7 different

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.
