Development of HighEfficiency Thermionic Power Generator, Phase I

Completed Technology Project

Project Introduction

In space exploration missions where photovoltaic power generation is inadequate due to a lack of sunlight, and for missions with moderate power draw and increased mobility requirements, thermal-to-electric power generator systems using radioisotopes as heat sources provides NASA with a viable solution. Nanohmics Inc. proposes to develop a novel high efficiency thermionic thermal-to-electric converter (TTEC) using nanostructured emitters for integration with radioisotope thermoelectric generators application. The emitter material employed in the proposed TTEC device allows the device to be operated in harsh and high temperature environment. More »
