But doesn't charcoal rquire some minimal diameter to be efficently made?
I can image OP's context has it that only the smallest pices of wood can be sparsed for burning,
and any available wood charcoal would be used for more valuable purposes like
Water purificaton, soil ammendment and mulch.
Also i am really interested if a
rocket stove would be efficient.
