The concept of using fire to cool the earth is not new. Awareness of the remarkable climate cooling power of biochar is growing by leaps and bounds. Believed to have been first created by Amazonian jungle charcoal makers thousands of years ago and known as Terra Petra in Brazil, Biochar is today the subject of thousands of peer reviewed scientific articles into its remarkable ability to sequester carbon and help restore agricultural fertility which has been ravaged by 80 years of a supposed green revolution based on herbicides, pesticides and inorganic fertilizers.

Kon Tiki style biochar

For thousands of years people have been producing biochar with open fire. Here we use a modified Kon-Tiki flame curtain kiln. In this way we use ancient techniques of fire making combined with modern thermodynamics to produce high quality char with low emissions.
