[Stoves] "stove-acceptance" of char-making [TLUD] stoves.

[bukenya emmanuel]

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

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.

Dear Stovers,

            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.
