These known magnetohydrodynamic-generator (MHDG) configurations are briefly examined: (1) Continuous-electrode channel, Faraday emf; (2) Sectionalized-electrode channel, loads fed with Faraday emf's; (3) Sectionalized-electrode channel, Hall emf; (4) Montardi scheme. The potentialities of these two combined configurations are considered: (5) A coaxial channel with a two-component magnetic field in which the emf is generated by both Faraday and Hall effects; no insulating wall is needed, and a small-size super-conducting magnetic system is applicable; (6) Same, but the electrodes are sectionalized as in (2). The latter two schemes are explored analytically. It is found that: (1) Scheme 5 with continuous electrodes obviates the difficulties connected with insulating walls and inserts in the channel; however, its specific (per unit volume) electric power is only 1/12 to 1/3 as high as that in other MHDG schemes; the specific power can be stepped up considerably if a higher temperature - and, therefore, higher gas conductivity - be used; (2) The characteristics of scheme 6 approach those of scheme 3; however, scheme 6 has no advantages stemming from the absence of insulating inserts; (3) The axial symmetry of the working flow and the applicability of simple torus superconducting magnetic systems are the two advantages of magnetohydrodynamic flows using the Hall effect and two-component field.
