How could solar concentrators supply heat for an MHD generator?

In theory, solar concentrators could supply the thermal energy required for a magnetohydrodynamic (MHD) power generator by heating a working fluid to temperatures high enough to achieve thermal ionization.1

While conventional heat sources like fossil fuels are typically used to produce the high-pressure, electrically conducting gas necessary for MHD systems, solar-based systems remain a potential alternative. The primary challenge for this application is the development of solar collectors capable of operating reliably at these extreme temperatures for extended periods. If such technology were realized, it could provide the necessary heat to ionize the gas, allowing the kinetic energy of the expanding plasma to be converted directly into electric power as it passes through a magnetic field.21
