Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The alkali metal thermoelectric converter is a thermally regenerative electrochemical device for the direct conversion of heat to electrical energy. It is characterized by high potential efficiencies and no moving parts, which make it a candidate for space power applications. This device accepts a heat input at 900 K-1300 K and produces direct current with predicted device efficiencies of 15-40%. In this device sodium is driven around a closed thermodynamic cycle between two heat reservoirs at different temperatures. The unique feature of the AMTEC cycle is the isothermal expansion of sodium vapour through a solid electrolyte which causes sodium atoms to separate into sodium ions and electrons.
