Phonon-Glass Electron-Crystal

A phonon-glass electron-crystal (PGEC) is a high-efficiency thermoelectric material that is used by humanity in many solid-state energy generation systems. While the first PGECs were developed in the early 21st Century by Voima Tech Industries as Voimaflex; they have since evolved and increased greatly in efficiency. They are used frequently in large-scale power plants as well as portable fission batteries; they are also usually stacked for greater efficiency.

Heat removal from the cold side of the thermoelectric generator is a significant challenge with PGECs, especially at smaller scales and higher power densities. For this reason, generators often utilise exofluids for energy transfer, which are able to achieve an extremely high rate of thermal conductivity. High-efficiency nano-machined radiators are then able to efficiently radiate the waste heat into the surrounding atmosphere or a liquid.
