SOLAR-DRIVE MAGNETOHYDRODYNAMIC GENERATOR Russian patent published in 1997 - IPC

FIELD: power engineering; conversion of concentrated electromagnetic radiation energy of sun into electric energy. SUBSTANCE: generator has chamber 1 with heat-insulating walls covered inside with heat-reflecting material which houses hollow heating element 2 gas-tight on surface and placed in a spaced relation to chamber walls; it is made of high-melting conducting material with surface layer of material with low output of electron; it also housed electrode 3 connected to heating element 2, magnetohydrodynamic channel 4 with electrodes 5 joined with outlet hole of chamber 1 aligned with hole of heating element 2, magnetic system 6 that builds up magnetic field in channel 4, DC voltage supply 7 connected to electrode 3 of heat exchanger 2 and electrode 5 closest to heating element in magnetohydrodynamic channel; voltage supply positive pole is connected to channel electrode and its negative pole, to heat-exchanger electrode; it also has high-melting element 8 for introducing concentrated solar radiation placed along channel axis on its output side. EFFECT: improved design. 2 cl, 2 dwg
