Exactly.
The investment to make charcoal in an inefficient way is about 6$: 3$
for a spade or a shuffle,
3$ for an axle and the "sweat equity", not to forget bags for 30
cents............
The wood itself you are "steeling" from a remote place...
Thats the secret making some income where cost calculations would fail
otherwise!

Distributing or disseminating "low-cost retort kilns" will not work
without a "project structure".
It will not work just distributing building manuals to non-technicians .
It should not be done without assuring the wood comes from a sustainable
place.
The project needs to give easy access to the metal sheet needed, and
easy access to some pre-assembled parts like the fire-box cover.
And the project needs to give guidance and training.....
But isn't this the case with most new technologies you introduce in
South Countries (tilapia fish pools, goat projects, improved stoves etc.)

Much easier it will be to approach forestry plantations and energy-wood
plantation owners.
As the carbonization of a part of their wood- will add value to the product.

("Without charcoal," writes John Uhlmann and Peggy Heinrich in their
book, /The Soul of Fire/ (University Books, 1987),
"mankind probably never would have made it out of the Stone Age.
Charcoal provided the intense heat necessary to melt iron and other
metals.")
