In this video you can see two of my biochar methods that I use, a 20liter TLUD gasifier that is gasifying stove pellets and its heat is used to heat up a 60 liter retort which sits inside an insulated 200 liter drum.
The smoke is passed through a cyclone filter followed by a condensation system to extract wood vinegar.
The copper pipe from the condensation system was soldered using one of my smaller TLUD gasifiers.
This is a very promising innovation, Martin, but it is above me technically. Maybe some day I will develop the skills to do something like this.
