Abstract:     An MHD power generator includes a pair of electrode units between which a plasma stream flows from a plasma stream generating source. Each electrode unit comprises a plurality of segmented electrodes connected with each other with an insulating material disposed between the next adjacent segmented electrodes. The segmented electrode is made of magnetic material such as iron and cooled by an electrode cooling device. A pair of electrically insulating plates are mounted i.e. one on the upper surface of the electrode units and the other on the lower surface of the electrode units to define a plasma passage. A plurality of lead wires are each connected to a corresponding segmented electrode so as to take out an electric power which is generated in the plasma passage.

What we claim is:     1. An MHD power generator comprising means for generating a weakly ionized plasma stream, a pair of electrodes made of magnetic material and arranged opposite to each other, means for defining a plasma passage between the pair of electrodes through which the plasma stream flows from the plasma stream generating means, means for cooling the pair of electrodes, and a plurality of output lines each connected to the mutually facing electrodes so as to take out an electric power generated therebetween.
