Title: Solar-powered liquid-metal MHD power systems

Abstract

The two-phase liquid-metal MHD power cycles coupled to solar collectors have potentially a higher efficiency of converting solar energy input into useful electrical power output for all collector temperatures. The MHD interaction is a volume effect, so that efficiency is essentially independent of design level down to fractional-megawatt size, and the performance is attractive even at approx. 50 kWe size. The use of two working fluids in the energy-conversion system is advantageous in coupling the conversion cycle to solar collectors and direct-contact boilers can be used to obtain higher conversion system temperatures. Two liquid-metal MHD systems of interest for solar collectors are presented and explained. Liquid metal MHD conversion systems appropriate to low, intermediate, and high collector temperatures are described along with initial efficiency and cost results.
