The Alakli Metal Thermal to Electric Converter (AMTEC) technology is extremely amenable to a modular configuration. Several modular designs have been proposed for coupling to the radioisotope general purpose heat source (GPHS). Current AMTEC cell designs, producing approximately 5 W at over 20% efficiency, can be integrated into a radioisotope heated module that provides 10–28 per 250 Wth GPHS. The mass of these modules is approximately 4 kg. The cell design used in this concept is under development. The first generation model has already been operated for one year. Smaller, higher efficiency cells are now being fabricated.
