Douglas Clayton has updated his video about making Biochar in the Jolly Roger Oven.

He has a bit of help from Hugh (making jokes about steam activating the char). It's a great video, well worth the watch.

If you are new to the Jolly Roger Oven, Doug has more detail in his first video

more about the the line of thought behind the Jolly Roger biochar method can be found here:

For those of you in New Hampshire, Doug Clayton and Intuitive Biochar is in Jaffrey, NH 03452

Douglas Clayton and Hugh McLaughlin

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.
