Carbon particles entrained in the gas flow into a magnetohydrodynamic generator are electrostatically charged from a source of high voltage and then function as charge carriers in the MHD process. Lower flow temperatures may be used and seeding with alkali metal salts is unnecessary as the MHD process becomes independent of thermal ionization of constituents of the gas flow.
