#2 Baking BioChar in Earth Pit Oven

This method of making biochar is the most successful I have ever had in over a decade of making, thinking about, watching videos on, attending presentations and demonstrations on, all while making biochar at home in my wood stove and in my backyard. I blogged in detail on this test click here:

Pit Baking Biochar opens up a host of creative new ideas and concepts for adoption of systems, uses and adaptations for agricultural communities and 3rd world people's because the materials for making it are as local and cheap as a hole in the ground - (which, within a multitude of functions and designs) is basically what it is.  And, while it maximizes heat efficiencies in the the making of char, it delivers the remainder "waste" heat in a manner easily available and adaptable for domestic or farm or even urban and manufacturing uses.  
I believe when properly constructed, it is safer to work around than an open or above ground fire, or a barbeque (I dare add and emphasis the word "MUCH"). Because I believe this system is scalable, I believe also that pit baking biochar opens up a rainbow of options for both the backyard tinkerer and the civil engineer.
Check out my blog "I've been wrong before . . .)for more details along with design sketches (which is all you need to put together your own) and my own analysis and conclusions. There were a few false assumptions I made and proved wrong with this experiment.
