Matt has done it all, from mud to ceramic insulation, j tube to batch, indoor and outdoor, cooking and space heating.
He is an rocket stove innovator, who took the known and ran with it into the "impossible", and just kept going.
I kinda dig his work, a little.
Most importantly for your question, some his earliest work involved multi use out door rocket cooker.
He is a strait up carnivore, and his rocket stove in the video definitely can smoke some meats.
