By rad you mean radical? Can you share some more, like how much fuel in a load, how long does it lasts, how clean is the exhaust on low power and... pipe temperature at the bottom of the barrel?
By radical, I mean cool. The stove is very unique. It is the first rocket stove hooked up to a mini mass that I have seen.
This stove was built by Studentoflife2013. Here is the direct link on Youtube. You can read his comments on the build and ask questions.

Mini is used in the title because the size of the mass is much smaller than the norm.
