I have the best biochar cone kiln. I can probably do the same thing with a cheap tractor supply fire ring. Just use some soil to build up the edges.
I'm looking for suggestions on a biochar retort. I'm chatting with a guy about fabricating one from sheet metal.
Any idea on what to do? A square Kontiki style would probably be the most cost effective. It seems that a cone shape may be more efficient?
Any and all ideas will be considered...except for nostr:npub1w6959jfmvcx70uyyu2hlkwlecllfl9qy74gqpasrmeswhm5fm30q9ufw2l.
