[Stoves] Simithsonian article Re: Test of Gasfier-stoves (FD and ND) and results.

[Paul Anderson]

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.
