Interesting article,
* however why is it so awful ?
A) to weight the wood before carbonisation
B) estimating the water content of the wood,
C) to weight the charcoal received,
D) calculating the efficiency.

2ndly I do not understand the table:
Wood moisture 12% = 100% yield
20% = 76% yield
60% = 44% yield   etc.
