New Design Promotes Thermoelectronic Generator Concept

Posted on: 01/06/2014
Researchers with Augsburg University and the Max Planck Institute for Solid State Research in Germany, and Stanford University, United States, have developed a thermoelectronic generator model that they say will convert heat energy into electricity with high efficiency.

Thermionic generators use the temperature difference between a hot and cold metallic plate to create electricity. Previous models have been ineffective because the negative charges of the electrons leaving the hot plate repelled other electrons as well, effectively killing the current.

This latest research circumvented the problem using an electric field to pull the charge cloud away from the hot plate, allowing electrons to fly to the cold plate.
