20080317657 | Systems and methods for capturing, isolating and sequestering carbon from CO2 in the atmosphere in the form of char produced from biomass feedstock - The invention is a system and methods whereby biomass is gasified in a reactor vessel producing carbon char for the purpose of sequestering that char in soil, thereby reducing the carbon in the atmosphere.
