Abstract: Prevention of buildup of material on the cathodes and anodes in direct current magnetohydrodynamic devices which would otherwise occur is substantially reduced if not prevented by providing periodic current reversal in the electrodes. Such current reversal may be achieved in accordance with the invention by providing electrode segments around the periphery of the channel, maintaining a fixed relationship between magnetic field and means coupling appropriate electrode segments to the load and rotating the channel.
