Hugh McLaughlin and I have been working on describing our retort over TLUD char maker, which Hugh has christened the Jolly Roger Oven or " J-RO". The current draft of our paper The “Jolly Roger Ovens” family of Biochar-making devices in pdf, and attached to this story

From the YouTube notes:
A 30 gallon retort heated by a 55 gallon TLUD is the basic idea. I've been a biochar enthusiast for 5 years now and riding the learning curve on how to make and use biochar at home. This device can run very cleanly. The cleanest I have seen for a simple batch device.

Playing with large, red hot, drums is a safety concern. So be thoughtful and careful if you try it. I am looking forward to making improvements to the design and looking forward to seeing anyone elses. This is an open architecture. If you come up with improvements, please share them.

As the world of biochar expands, the need for definitive research to answer core questions grows. One such question is “What is the role of adsorption and when does it make a pivotal difference in growing situations?” Answering those questions has been hampered by the historical absence of adsorption as a monitored property in soils and soil components (as compared to CEC) and the lack of a reliable method to create low and high adsorption biochars. While there is little that can be done about the former situation, the later may have a fairly facile solution, which will be presented here.

This is a nice series on growing your food "close to home" which also features Hugh Mclaughlin giving a nice presentation about making biochar and incorporating it into your garden.

Biochar is a vague term that applies to a potentially broad class of charcoal materials intended for addition to soils. Many raw materials and conversion processes can lay claim to producing biochar, and the resulting biochars will have different characteristics. The purpose of this discussion is to formulate a simple scheme for characterizing biochars before addition to soils. Efforts will be made to discuss the logic behind the individual characteristics, in addition to the limitations of the individual assays.

The presentation and content here is consistent with the paper titled
