A discussion of the history and possibilities for terra preta.
“Terra Preta: Black is the New Green”
A scholarly paper from Cornell University. Abstract: “At best, common renewable energy strategies can only offset fossil fuel emissions of CO2 – they cannot reverse climate change. One promising approach to lowering CO2 in the atmosphere while producing energy is biochar bio-energy, based on low-temperature pyrolysis.”
