The two-phase-generator, liquid-metal magnetohydrodynamic (LMMHD) energy conversion system has an inherently thermodynamic efficiency for the same heat source and sink temperatures and is better suited for cogeneration than other conversion systems. For solar applications, attractive efficiencies in comparison with alternative systems are calculated at approx. 580 K and approx. 1090 K, and cogeneration advantages are indicated. For coal applications, recent coal combustion gas-copper reaction results show that the copper can be used to control SO/sub 2/ emissions. The calculated cycle efficiencies are comparable to those for open-cycle plasma MHD at combustor temperatures of 2220 K or less.
