very encouraging news about the project. I am happy to hear

</div>
</blockquote>
In the pilot project in Deganga, the earliest stoves have completed
over 4 years of virtually daily usage (with annual confirmations by
the carbon credit verifiers). This is with maintenance and
repairs. The major parts have many years of life ahead of them.
The repairs are on the grate and on the fuel chamber (innermost
cylinder). The project purchases the produced charcoal, so the
users are quite good at dumping out the char at the end of the
pyrolysis stage, thereby helping protect the grate and lower
sidewalls.<br>
<br>
The fuel cylinder has a "sacrificial cylinder" that is inside the
main wall of the fuel cylinder. When it is showing stress, it is
removed (one screw) and inverted so that the less-stressed upper
portion becomes the bottom area. I am asking the project
implementer (MB) about the frequency of the repair work. The
cylinders are produced with seam welding of stainless steel sheets.
Look good and hold up well.<br>

The stoves are assembled at one location (with quality supervision)
from components from 5 different suppliers whose components are
clearly comparable with each shipment. There is surplus production
capacity in the Kolkata area to greatly expand the number of pieces
of each component. <br>

I agree. Just need to find the time to do the write-up. I hope to
do it before ETHOS. By January 2018 the project will be passing
50,000 stoves in use, and (I anticipate) that the number of stoves
per month will be over 4000, with new expansions of the project
coming on-line as fast as funding will allow. (I will discuss
funding issues in a later message.)<br>

Only yesterday did I return from India (GACC Forum and then 9
days at the TLUD (woodgas) project in West Bengal near
Kolkata. Passed 40.000 Champion TLUDs, and increasing at
3000+ per month. More messages will follow.<br>
