Dear Otto and all stovers.
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).
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.
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.
Or maybe TLUD-ND is not yet ready for merit acknowledgement. If not,
then let's hear why not.

Dear stovers,
About test of gasifier stoves, forced draft and natural draft.
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.
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.
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)
We are planing field tests for the natural draft gasifier in the new
year to be done in Zambia, Kenya, Uganda and TZ.
Hopefully we can include the forced draft gasifier from Phillips, too.
