Peterberg style batch box burner. Different to the ‘J-tube’ style rocket stoves I have made so far in that all the wood is placed in the batch box at once. The idea is that the precise, calculated dimensions of the batch box facilitate a maximum-efficiency combustion of the wood.
No idea what I will end up doing with the burner yet. I made it out of sheer curiosity. What is really nice is that this tiny one is move-able by two people.
