[Stoves] This Stove can Save 4 big trees and $884 every year

Crispin,

Are you saying that if insulated, and hot enough, that the pyrolysis 
reactions will give sufficient H2 and O2 to combust (become simple 
water) even into the center of very thick logs?

I will allow for some (but not massive fire) extra external heat to be 
added as needed, because the NET heat of pyrolysis and this combustion 
is endothermic (slightly).   I also allow some extra heat because the 
biomass will not be totally dry so some heat is needed to bring up the 
temperature of that inert H20.

Other issues:  What about all those other tars and oils and vapors that 
are combustible but for which there is not sufficient Oxygen inside the 
biomass molecules?   Are you expecting this to drain? Or to remain 
inside the "char" that would be loaded with such "gunk"?    That would 
be interesting char for burning, but not as biochar for soils and plants.
