Patent number: 11232880Abstract: A lattice energy converter (LEC) is disclosed that produces ionizing radiation and/or electricity based on the thermal energy in the lattice of a specially prepared working electrode comprised in whole or in part of hydrogen host materials that are occluded with hydrogen or the isotopes of hydrogen and wherein the hydrogen host materials may include vacancies, superabundant vacancies, and other lattice defects. When the hydrogen host material is occluded with hydrogen, the LEC was found to self-initiate the production of ionizing radiation and, when the hydrogen host materials are in fluidic contact with a gas or vapor containing hydrogen or isotopes of hydrogen, the LEC was found to self-sustain the production of ionizing radiation. When the LEC includes one or more additional electrodes or electrode structures, the ionizing radiation was found to be converted to electrical energy. Materials that are normally considered to be radioactive are not required.Type: GrantFiled: May 28, 2021Date of Patent: January 25, 2022Assignee: Inovi, Inc.Inventors: Frank E Gordon, Harper John Whitehouse
