I have now done tests with a pit, and contrasted with the retort.

For information on the retort see: http://terrapreta.bioenergylists.org/content/small-kilnretort-my-farm-ahualoa-hawaii and http://tech.groups.yahoo.com/group/biochar/message/11011

Since the retort had issues, i looked for a way to get larger capacity and fewer parts to wear out. The idea: a pit lined with concrete blocks, which can be covered with a piece of sheet metal and soil.

I gave a 40-minute talk on biochar recently to the Kona Coffee Grower's Association (here on the island of Hawai'i).

10 minutes of it got uploaded: http://www.youtube.com/watch?v=42gr_1whjc8

It covers the basic carbon cycle, biochar's agricultural use, interaction with nutrients and microbes, reversing fossil fuel use, appropriate sources of renewable biomass.. my sources of information are, basically, this mailing list, and my own experiences making and using biochar.

A few unburned logs go to the side, the rest goes into a wheelbarrow

It's quick and simple to make a fire in the box

So, also trying a lower-tech solution: a simple pit, dug down and lined with blocks
