My take on this... distributed rural biochar production and application should be limited by two factors - the need for distributed energy and soil improvement. We are a long way from fulfilling either of these and they should be balanced (not waste the energy).  We still don't have the simple low cost equipment at a community scale... but we do have TLUD's at a family scale.
