Alkali-metal thermal to electric converter

An Alkali-metal thermal-to-electric converter (AMTEC) is a type of thermal energy conversion device that directly converts thermal energy into electrical energy using alkali metals, typically sodium or potassium, as the working fluid. The basic principle leverages the high vapor pressure and conductivity of alkali metals at elevated temperatures. ### How It Works: 1. **Heating**: The alkali metal is heated to high temperatures, where it vaporizes.
