[Stoves] Applications of TLUD heat - not for cooking and biochar and terra pretta

[Paul Anderson]

Michael,

At least as important as the source of the heat, the "dryer" device (the 
application of the heat) needs to be described. Could be several models, 
or just one.   Please describe the options.   And give us some numbers 
of quantities, size of pieces, moisture content at start and finish, etc 
so that the quantifiers among us can make some calculations on amount of 
heat needed.

Paul
