Biochar kiln progress

Just wanted to share a few photos with you all, I have made some progress with the biochar retort kiln. I have not mortared anything together yet, but I did stack the bricks in the formation they will eventually be mortared. I did start a fire in it, and it burned horizontally just like it was supposed to, pretty amazing to see. This will be a two barrel design just like shown in the photo, but instead of just a burn barrel on the bottom, the rocket stove will be incorporated.

Are you going to redirect the gasses from pyrolysis back into the rocket?
