Thermionic Energy Conversion. This process starting with thermionic emission produces a current of electrons that can subsequently drive an electrical load to produce work. Unlike the conventional indirect methods for generating electricity from heat sources no intermediate form of energy is required and no working fluid except the flow of the electrical charges themselvesare involved in the process. HE thermionic energy converter is a nonmechanical gaseous-electronic device for converting heat directly into electric power by thermionic electron emission. Thermionic Energy Conversion Centers goal is to design fabricate and characterize direct energy conversion systems that meet the above requirements.

HE thermionic energy converter is a nonmechanical gaseous-electronic device for converting heat directly into electric power by thermionic electron emission. While such transformations have been historically limited by low efficiencies recent advances have made thermionic energy conversion a viable source of energy generation in certain applications. Thermionic energy conversion is the process of converting heat directly into electricity using heat as the source of energy and electrons as the working fluid. A thermionic converter is essentially a heat engine converting thermal energy directly to electricity. Thermionic energy conversion TEC for direct conversion of heat to electrical energy occurs when electrons thermally emit from a hot surface traverse a gap and are collected by another surface. Thermionic energy conversion is a process by which thermal energy can be transformed into usable electricity.
