Vithusa Biochar Kiln

Vuthisa Technologies in South Africa have been working on improving the Portable Metal Kiln Charcoal Making Method and using a retort design to reduce emissions and improve efficiency making charcoal.

They have a great description with lots of detail on their web site: http://vuthisa.com/biochar/
as well as a Google Group:

In short the system is composted of an outer drum, often fabricated of sheet steel enclosing an inner set of 30 gallon drums.
