This kiln is clean. This video proves it. The Ring of Fire Biochar Kiln is designed to burn the smoke.
Tabor made this great video showing how he turned a giant pile of brush into biochar - all by himself.
Down to Earth: Biomass to Biochar and Storing Carbon in the Forest Soils. A short video about using the Ring of Fire biochar kiln in the Redwoods.
The great forests of the Western US are mighty storehouses of carbon and life. But poor management, exclusion of natural fire and climate change are having a terrible impact. We need boots on the ground, converting woody debris to biochar to restore healthy forest soils and sequester carbon. This video describes the methods and technology for making biochar in the woods, and proposes a program for paying our youth to do this important work to save our forests and our climate.
Kelpie Wilson presents techniques for making biochar on site at the first US Biochar Week
