  • Patent number: 11876254
    Abstract: A solid-state thermal battery system is disclosed herein. The system includes a stationary thermal storage medium that can be charged by adding heat to the thermal storage medium. Actuated heat engines can be utilized to discharge the solid-state thermal battery, converting the heat stored in the thermal storage medium into electricity. The heat engines are actuated in a manner that reduces thermal gradients in the thermal storage medium to increase the efficiency of the system. In one embodiment, the thermal storage medium is contained in a main chamber of an insulated container. The heat engines are stored, when idle, in an ancillary chamber adjacent to the main chamber and moved into the main chamber by an actuation system to begin discharging the solid-state thermal battery. The heat engines follow a path during discharge to dynamically move between regions of the thermal storage medium to reduce thermal gradients induced therein.

  • Patent number: 10566094
    Abstract: Enhanced Coulomb repulsion screening around light element nuclei is achieved by way of utilizing electromagnetic (EM) radiation to induce plasmon oscillations in target structures (e.g., nanoparticles) in a way that produces high density electron clouds in localized regions of the target structures, thereby generating charge density variations around light element atoms located in the localized regions. Each target structure includes an electrically conductive body including light elements (e.g., a metal hydride/deuteride/tritide) that is configured to undergo plasmon oscillations in response to the applied EM radiation. The induced oscillations causes free electrons to converge in the localized region, thereby producing transient high electron charge density levels that enhance Coulomb repulsion screening around light element (e.g., deuterium) atoms located in the localized regions.

  • Patent number: 10264661
    Abstract: Enhanced Coulomb repulsion (electron) screening around light element nuclei is achieved by way of utilizing target structures (e.g., nanoparticles) that undergo plasmon oscillation when subjected to electromagnetic (EM) radiation, whereby transient high density electron clouds are produced in localized regions of the target structures during each plasmon oscillation cycle. Each target structure includes an integral body composed of an electrically conductive material that contains light element atoms (e.g., metal hydrides, metal deuterides or metal tritides). The integral body is also configured (i.e., shaped/sized) to undergo plasmon oscillations in response to the applied EM radiation such that the transient high density electron clouds are formed during each plasmon oscillation cycle, whereby brief but significantly elevated charge density variations are generated around light element (e.g.
