Abstract
The sodium thermoelectric converter using the sodium ion conductor ( beta double prime -alumina) is a device to convert directly heat energy to electric energy. It is characterized by high conversion efficiencies (20 to 40%), high power densities (2 w/cm**2), no moving parts, low maintenance requirements, high durability, and efficiency independent of size. Because of these merits, the sodium thermoelectric converter is one of the most promising candidates for aerospace power systems. Though its R&D efforts are now under laboratory study, the power density of 1. 1 w/cm**2 and the conversion efficiency of 19% have been demonstrated.
