Аннотация: A new concept of a closed cycle MHD generator without alcali seed has been suggested. The essence of it is the use of the high-energy electron beams technology for a nonuniform gas-plasma flow in MHD channel creation. At the inlet of MHD channel in supersonic flow of noble gas (He) plasma clots with a density about 1015cm-3 are formed by pulsed intense electron beams with energy about 100 keV. Gas flow drives these clots in a cross magnetic field along the MHD channel which has electrodes connected with a load by Faraday's scheme. Because the nonuniform gas-plasma flow does not have the conductivity in the Hall's EMF direction a Faraday's current can flow only through the narrow plasma layers. The energy dissipation and Joule's heating in MHD channel support the nonequilibrium conductivity in these plasma layers.
