"adam-retort" a low-cost retort kiln for a more environmentally
friendly production of charcoal from biomass.
Reduces emissions of up to 75% of methane, which is normally released
into the atmosphere by traditional earth mount kiln.
Saves about halve of the wood- which is needed to produce the same
amount of charcoal with a traditional kiln!
