E, Kelpie, aloha kaua-

It is nice to see your interest in JR Ovens and particularly in getting them on the open source page. I think that they are destined to become the arch-typical biochar oven (Biochar ovens http://www.biochar-international.org/technology/production). And I think they are destined to play a big role in meeting biochar’s potential in climate change mitigation from thinly distributed feedstock (http://www.biochar-international.org/regional/ubi July update). I would hate to see any commercial impediments do to profiteering holding back implementation, though it would be nice to see some well made ‘back yard’ ovens on the market for urban/suburban yard trimmings.
