Excellent open source pyrolysis kiln from Switzerland for biochar production with a very clean burn. Some implements are already available and everything is open source.
Ithaka Institut says: While most of the biochar produced during the last 5000 years was produced with open fire, modern pyrolysis suppresses the fire. The separation of the carbonisation and the flaming of the pyrolysis gases make pyrolysis technology prone to failure and expensive which is one of the reasons why the biochar technology did not have yet it's breakthrough. The Kon-Tiki flame curtain kiln re-connects biochar making to the ancient wisdom and craft of fire making and combines it with smart design based on modern thermodynamics to produce high quality char with low emissions.
My (Rasmus) opinion: these types of open-burn kilns appear to have some advantages over those "barrel-in-a-barrel" retorts that were advocated in the past. The char produced with open burn kilns may be of higher quality. This kiln does away with a metal barrier which is costly, labor-intensive to make, and corrodes easily.
