  • Patent number: 11563217
    Abstract: A method of producing electrodes includes selecting a palladium alloy, annealing the palladium alloy at a first temperature above 350° C., cold working the palladium alloy into a desired electrode shape, and annealing the palladium alloy at a second temperatures and for a time sufficient to produce a grain size between about 5 microns and about 100 microns. The method further includes etching the palladium alloy, rinsing the palladium alloy with at least one of water and heavy water, and storing the palladium alloy in an inert environment.

  • Patent number: 11008666
    Abstract: An exothermic reaction assembly includes a reaction chamber and a generator operative to generate an AC electrical signal and apply the signal to the reaction chamber by superimposing the AC signal over a DC signal. A gas manifold and controller is operative to connect a vacuum pump and one or more gas chambers to the reaction chamber and to control a pressure of the reaction chamber. The signal generator is operative to create a plasma in the reaction chamber by superimposing the AC electrical signal to the reaction chamber over the DC signal. The gas manifold and controller are operative to adjust the pressure within the reaction chamber to achieve a predetermined plasma frequency.

  • Patent number: 10767273
    Abstract: An electrolytic method of loading hydrogen into a cathode includes placing the cathode and an anode in an electrochemical reaction vessel filled with a solvent, mixing a DC component and an AC component to produce an electrolytic current, and applying an electrolytic current to the cathode. The DC component includes cycling between: a first voltage applied to the cathode for a first period of time, a second voltage applied to the cathode for a second period of time, wherein the second voltage is higher than the first voltage, and wherein the second period of time is shorter than the first period of time. The AC component has a frequency between about 1 Hz and about 100 kHz. The peak sum of the voltages supplied by the DC component and AC component is higher than the dissociation voltage of the solvent.

  • Patent number: 10522018
    Abstract: A system includes an energy production device, a tampering detection system comprising a plurality of sensors, and a control system in communication with the plurality of sensors. The control system is configured to detect a candidate for a tampering event, determine if the candidate is a tampering or a normal operational error by comparing a first order condition to a predetermined threshold, and, when the predetermined threshold is not met, comparing the candidate to a subsequent order condition until the threshold is met, and direct an undertaking of a countermeasure when the candidate is a determined tampering or undertaking a maintenance when the candidate is a determined normal operational error.

  • Patent number: 10385468
    Abstract: An exothermic reaction of hydrogen/deuterium loaded into a metal or alloy is triggered by controlling the frequency of a hydrogen/deuterium plasma in a reaction chamber. The plasma frequency is controlled by adjusting its electron density, which in turn is controlled by adjusting the pressure within the reaction chamber. An exothermic reaction is generated at certain discrete plasma frequencies, which correspond to the optical phonon modes of D-D, H-D, and H—H bonds within the metal lattice. For example, in palladium metal, the frequencies are 8.5 THz, 15 THz, and 20 THz, respectively.

  • Patent number: 10295520
    Abstract: Methods and apparatus are disclosed for testing simultaneously multiple fuel materials for suitability of producing excess heat. In some embodiments, multiple fuel materials are placed on a substrate with a thermoelectric converter inserted in between each fuel material and the substrate. When a triggering condition is applied, exothermic reactions may be triggered in some of the fuel materials. The voltage output of the thermoelectric converters is a direct measurement of the temperature of each fuel material, which is an indicator of whether an exothermic reaction is taking place in the fuel material. A known fuel material may be included in the testing array to establish the baseline of voltage readings.

  • Patent number: 10053362
    Abstract: A gas-loading and packaging system is provided for loading a solid material used in a hydrogen fuel cell with gas and packaging the solid material in a sealed container. The gas may comprise a hydrogen gas or other gas. The solid material may, for example, comprise palladium, a nickel alloy, platinum, or other metal. The solid material is loaded with gas by exposing the solid material to the gas under high pressure. When the solid material is exposed to gas under pressure, the gas absorbs into or adsorbs onto the solid material. The mass of the solid material is continuously monitored and used to determine when the solid material is loaded with the desired amount of gas. After the solid material is loaded with gas, high pressure is maintained while the solid material is packaged in a sealed container that is capable of retaining the high pressure gas.
