[Stoves] Terra preta from wood fires in Peru

[Crispin Pembert-Pigott]

Dear Friends

 

Lovely story from Josiah Hunt.

Wood fired ovens and cooking fire generate charcoal naturally. It has been
placed into the local garden soils for a very long time, according to
tradition.

 

Question for Ron Larsen: is the wood fraction consumed to make such charcoal
part and parcel of the fuel consumption of the stove, or not? If we can
agree on the answer to that question, we will achieve much.

 

Regards
Crispin
