Dear Dean and all,

What tests are you calling "recent"?   Jim is into his third or fourth 
set of stoves?   The recently published paper is actually of data show 
to Stovers at the Lima Forum 1.5 yrs ago.

In that group, there was    A     TLUD-ND.   A  meaning one.   It was a 
prototype unit, and yes, it did very well.  The Champion TLUD by Servals 
in India in production since 2008 was not included.

Oh yes, there was also the test results of the gasifier from ARTI.   It 
did not perform as well and has resulted in a designation of a lower 
performance gasifier.   (There are several reports such as by ACCES 
(World Bank activities with cookstoves) that are shown but labeled 
"DRAFT" and are not released.)   In my opinion, it does not utilize all 
of the known ways to  get better performance.   And why it is being 
promoted by GVEP in Kenya is beyond understanding.

I have heard that Jim is testing some TLUD-ND in this current round.   I 
have not seen the list of stoves selected for testing.   If you or 
anyone can direct me to that list, I would appreciate it.   I hope that 
it includes the Peko Pe by Wendelbo, the Champion by Servals, and the 
Mwoto by the Uganda BEIA project.   And maybe other natural draft TLUDs.

Otherwise, the only test results of TLUD-ND that I know of on the 
Internet are those of my Quad TLUD   (at www.drtlud.com    and elsewhere).

I will be so glad when we finally have results for the well made TLUD-ND 
units.
