Molecular Transport Mediated Direct Energy Conversion

Project: Research project


This project addresses an all new approach for direct conversion of heat into electrical energy. The concept is based on including inter-gap molecular species in a heat cell with low work function materials. The approach has the potential to achieve current density, output power and efficiency far beyond that of standard thermionic and thermoelectric cells. If successful, it is anticipated that the system will exhibit an efficiency greater than 20% at hot side temperatures of ~500C. Moreover, the larger gap characteristics of this approach would enable a manufacturable technology. These characteristics would enable application for heat reclamation in electric power systems.
