Abstract
A method for converting solid organic fuels, most particularly coals, into high temperature gases that can easily be transformed into useful energy. This method employs a substantially closed reactor, referred to as a gasifier, having an internal reaction chamber or cavity made of materials that can tolerate the presence of oxygen at high temperatures, that possess low thermal mass, that limit or restrict the passage of heat, that function as almost perfect black bodies at high temperatures, and that are resistant to the abrasive effects of the solid fuels.
