Sure, biomass energy on its own is pretty compelling when we have so much of it around, but if you can do higher material throughput fixing half of the carbon is the icing on the cake.

Flame cap done well is very clean. The dynamics of the rolling vortex are an effective reburner and about all that goes up is CO2 and H2O. There are some papers (Cornelissen et al) that quantify kontiki emissions and I wouldn't want to compare a one-off heating event with GHGs that will be around for decades if not millennia. Run some tubing around the hot zone and heat a spa pool whenever you do a burn (I'm thinking about wrapping a length of soft copper around my big vessel for this very purpose). Add a few TEGs to run a little circulating pump.

I'd love to see your friend's rig. That sounds amazing.
