Аннотация: It is shown in the present work that space conditions form new requirements to MHD generator. The requirements differ qualitatively from those to a ground power plant. Apparently, beginning from the power level of 1 MWe the MHD generator is the preferable type of power plants. Exactly the MHD generators can make manned missions into deep space real. It is carried out the analysis of two types of MHD generator with non-uniform gas-plasma flow supposed to operate in space. The first type utilizing the "frozen ionization" phenomenon in non-equilibrium plasma clots is well combined with sun radiation concentrators. In such devices the level of specific power about 500 W/kg can be achieved. The second type assumes utilization of equilibrium plasma non-uniformities (T-layers). This type of MHD generator is supposed to work with gas-phase nuclear reactor, and in this combination the level of specific power could be of an order of 1500 W/kg.
