Dear Ron
We are back to repeating old arguments.
>…directly contradicted this sentence just in from Crispin
"The transport of charcoal (MJ per ton-mile) is much cheaper than
transporting wood and this difference dominates the charcoal economy"
A ton of damp wood and a ton of dry charcoal do not have the same energy
content. That is why people transport charcoal 600 km to Maputo and to Dakar,
not wood.
Regards
Crispin
