Abstract:

	This project relates to energy conversion systems that utilize a liquid-vapor phase
change with liquid metals, in particular, alkali-metal, thermoelectric conversion
(AMTEC) systems. These thermally regenerative, electrochemical devices for the direct
conversion of heat to electrical energy are being considered for use in space nuclear
and solar power generation. AMTEC systems are good candidates for space power applications
because they have high efficiency, long life expectancy, redundancy, and no moving
parts. The objective of this project is to assess the performance of a novel condenser
design for liquid metals, with specific application to AMTEC devices that are of
immediate interest. This design for a thin-film condenser is based upon capillary
principles, which take advantage of the high surface tension of liquid metals.
AMTEC technology could be applied to solar power conversion systems for Earth-based
power systems.
