[Stoves] A user-centered, iterative engineering approach for advanced biomass cookstove design and development

[Paul Anderson]

Ron,

Not correct.   The stove type was not TLUD.  It was essentially a 
trickle-feed forced air pellet heater (as in the home heating units) but 
made at the size of a cooking stove.   Nice work, but not a TLUD and no 
real chance to make charcoal because the pellets are burned to ash under 
the streams of forced air.   It might become very successful.   Good 
approach to designing changes.  But also heavy and expensive compared to 
the TLUD stoves that are currently having great success in West Bengal.
