[Stoves] COMPULSORY VIEWING!!! link from Re: The Aprovecho Newsletter - December 5th, 2014

Stovers,

Absolutely interesting and important is the just-released 8-minute video 
from Aprovecho.   Especially the final 2 minutes (starts at 5:50) need 
to be seen by all serious stove developers.  There ....

This is the first time these stoves have been openly shown, even though 
showing only a few seconds each.   Of exceptional note is the natural 
draft TLUD-ND stove designed by Kirk Harris!!!

One error (a very common misconception) is in the video at 6:46 
concerning the Aprovecho "Top Loaded Forced Air stove", putting it into 
a category with forced air TLUD stoves, saying that the "TLUD-FA design 
[that] is used in the Philips, BP, and Biolite stoves."  These four 
stoves use the migratory pyrolytic front (MPF) of the TLUD technology 
only at the beginning of burning, and then the fire is in the bottom 
(bottom burning with additional fuel added on top, as in standard (not 
MPF) up-draft gasifiers) with forced primary air blowing onto the 
charcoal located there, creating forge temperatures that require special 
materials (ceramics, cast iron, special metals) to avoid fast damage to 
the fuel chamber.  We do not know yet what is inside the fuel chamber of 
the Aprovecho "Top Loaded Forced Air stove".   These are cost factors.

This is all great progress!!!.   Congratulations Aprovecho!!!!

We will want to be comparing the cost of manufacture (or the sales 
price) of all of these stoves.   And the announced field trials of these 
5 stoves in 6 countries will be of great interest.

The first 6 minutes shows the sophistication of mass production of SSM 
company in China.   In the world of cookstoves, this is big business.

And  we will see these 5 stoves (among others) at the ETHOS meeting 
23-25 January 2015 in Seattle area.

Enjoy!!

Paul
