[Stoves] Help with rocket stove for Cameroon

[Huck Rorick]

I read the paper.  Very interesting.

Did you build the stoves with the chimney?  I want chimneys for our stoves
and had thought of adobe chimneys.  The one in the Ugandan design looks very
fragile.  Did you build any?  If so, how did they perform?  How thick walls?
How tall?  (The elbow looks very improbable to me).  

What kind of testing was done with the stoves?  Anything I can get access
to?  I'm curious how they determined efficiency?  Was any emissions testing
done?

Thanks,

Huck

I think the Ugandan design is appropriate for your service population.  
  I had to abandon it when my service population was displaced and they no
longer had easy access to clay soils.  Now that the resettlement areas are
stabilizing somewhat, I may revisit it and suggest that my local contact try
a pilot project.
