[Terrapreta] medium-size charcoal making - the tools?

[Greg and April]

I can't speak about the others, but, I have just this pass couple of weeks, talked to the developer of the Adam-retort / ICPS.

He says that he normally spends a month in country to give a training course.


Otherwise $1000 Euro + shipping charges ( about $1500 US before shipping ) for a construction manual ( about 30 color photos, 20+ pages of text, and about 15 pages of drawings/sketches ), with the permission to build a retort for your own needs, and e-mail technical support.
English translation of the manual not yet completed / available.


He says that it is adaptable to masonry construction if you wanted to make it with a refractory cement.

  The idea of charring forest wastes is great...but how could this be done on a farm or a community level?  How can we direct interested communities to the best technology available??


  Barrel-sized charcoal makers are great for house and garden level stuff, and Antal's flash carbonizer or the various pyrolysis sytems are great on a commercial level.  Is there any open-source do-it-yourself technology  that is ready to be made and used locally by communities on the medium level scale?

  2. the Adam-retort seems the most efficient, but it is very labour intensive to make and there's a lot of potential cracking in the double-wall masonary wall;  besides there are no drawings for it.
