In a first processing chamber, a feedstock may be combined with plasma from three plasma torches to form a first fluid mixture. Each torch may have a working gas including water vapor, oxygen, and carbon dioxide. The first fluid mixture may be cooled and may contact a first heat exchange device. Water in the first heat exchange device may be converted to steam to generate electric power. The output fluid from the first heat exchange device may be separated into one or more components. A syngas may be derived from the one or more components and have a ratio of carbon monoxide to hydrogen of about 1:2. The syngas may be heated in a second processing chamber and then cooled to form a second admixture. The second admixture may contact a second heat exchange device that may make steam to power a second electrical generator.
