Batch box rocket heater (massless)- PEM BB woodheat.straw.batchheater

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.

Rocket technology allows us to heat things very fast with wood.  Batch boxes hold a lot of wood and act more like a traditional wood stove.  Let's build one!

 

Here's an overview of one:


Minimum requirements:
  - Build a batch box rocket heater
  - Metal assemblies/components can be purchased (hint: Dragon Tech)
  - No mass
  - A lot of radiant heat surface
  - At least a 6" system
  - Includes a door on the batch box
  - Includes a secondary air feed

Provide proof of the following as pictures or video (<2 min):
  - The bricks you're starting with
  - Several points during construction
  - Finished batch box rocket heater
  - Fire going in the batch box
