<div class="moz-cite-prefix">Dear Otto and all stovers.<br>
<br>
Otto's message reminded me of something in that stoves article in
the Simthsonian. Did you notice that the comments jumped from
rocket stoves with some emissions limitations to stoves with
fans? The authors (and probably many others) simply jumped past
the micro-gasifiers that are with ND (natural draft). The
authors lamented the high prices of the stoves with fans (FA = Fan
Assisted). But the the ND units are already certainly under $20
and we are headed to $10 TLUDs in the near future (based on
pricing in Uganda). <br>
<br>
So, would everyone please try to remember that there are stoves
with quite clean emissions that do not require fans. Fans are
great, but while the price is high, let's at least acknowledge the
TLUD-ND technology.<br>
<br>
BTW, Who was interviewed by the Smithsonian author? Authors like
that just do not make up stuff. And they could have put in a
single sentence about ND gasifier stoves if they had been
informed. Someone (maybe several) in the Stove community failed
to acknowledge the existence of the natural draft TLUDs. I'd
like to think that the lapse was unintentional, but then what do
we say about their ability to represent all of the Stove
Community.<br>
<br>
Or maybe TLUD-ND is not yet ready for merit acknowledgement. If
not, then let's hear why not.<br>

Dear stovers,
<div><br>
</div>
<div>About test of gasifier stoves, forced draft and natural
draft.</div>
<div><br>
</div>
<div>The other day, I happend to find among my dokuments, a
paper from Phillips, that they actually had done some tests
back in 2006 and 2008 for the natural and forced draft
gasifier stoves.</div>
<div><br>
</div>
<div>It very much confirm the results, we have had for the
gasifier Peko Pe ND, apart from that the FD, are utillizing
the charcoal for cooking as well.</div>
<div><br>
</div>
<div>The paper is marked confidential, so I leave it to Phillips
to open up for the excact results from the tests, done in
labs. (Field tests remains)</div>
<div><br>
</div>
<div>We are planing field tests for the natural draft gasifier
in the new year to be done in Zambia, Kenya, Uganda and TZ.</div>
<div><br>
</div>
<div>Hopefully we can include the forced draft gasifier from
Phillips, too.</div>
<div><br>

<div>Back home in the cold - 21 C and light snowfall</div>
