Just wanted to share my second attempt in the rocket stove world. It is powered by broaudio's super hot 6" j. I ordered his plans and built my core. The plans were perfect. My stove is a heater plain and simple, designed to give me fast heat out in my workshop. I gotta say that my first couple burns are very promising. Zero, meaning cold, to 600f in under 30 minutes on 2 loads of sticks. The second, or top barrel really surrenders the heat quickly and radiates very well. I'm pretty sure this isn't an original idea but I haven't run across it yet. Let me know your thoughts on this idea folks. I'm all ears!
