[Terrapreta] BAMBOO CHARCOAL MAKING

[Gerald Van Koeverden]

Sounds like a new version of David yarrow's "Malawi Cigar"

 From a previous posting from him:

i forgot to mention the malawi cigar.

the homesteader lad's younger brother had lived in malawi with ordinary
village people.  he observed their method to turn a tree trunk into
charcoal.  robert klein will love this, and sean barry will turn purple.

as he dscribed the process, a family would selectg a downed log of a  
large
tree, and build a fire at one end of it.  the purpose of this fire  
was to
ignite the tree trunk wood.  while this initial fire was getting
established, they began heaping dirt all around and over the log,  
covering
and enclosing it with dirt.  once the end of the log was burning well  
with a
large red ember, they closed up the end of this earthen sarcophygus.   
they
left this slow-smoldering log alone undisturbed for a few days, making
occasional small digs to inspect the condition and progress of the burn.

the log slowly burned from end to end, like a giant cigar.  but  
instead of
ash, at the end of the burn, this hardwood cigar had become a large  
supply
of charcoal.  they only had to bust it up in chunks to use as fuel.
