Charcoal making stove - PEM BB woodheat.straw.charcoal

This is a badge bit (BB) that is part of the PEM curriculum.  Completing this BB is part of getting the Straw badge in Wood Heat.

Several permaculture and alternative energy activities require charcoal.  Let's build a stove to make charcoal and harness the heat!

Unfortunately this is such an awesome idea there aren't good pictures or videos of it out there.  Here's a basic video by Sean about how the process can be done inside your wood stove:


Minimum requirements:
  - Build a wood heating contraption that also generates charcoal
  - Gassification of the charcoal feed stock contributes heat to the process
  - Contraption doubles as a usable heat source (house, greenhouse, etc)
  - Can be a modified wood stove but needs to be permanently set up to produce charcoal

Provide proof of the following as pictures or video (<2 min):
  - A description of how your device will work
  - Several points during construction
  - Finished charcoal maker/heater
  - Charcoal feedstock going in
  - Fire underway in the contraption
  - Charcoal coming out
