Abstract: A neutron detection system may include a volume of neutron moderating material, and a plurality of solid state neutron detection devices disposed within the volume of neutron moderating material, wherein some of the neutron detection devices suitable for transduction of primary reaction products resulting from a neutron interaction event, wherein some of the solid state neutron detection devices include two or more solid state neutron detection elements, and wherein the solid state neutron detection elements are configured for omnidirectional detection of impinging neutrons.

Abstract: A hydrogen gas generation system is provided for use in a mobile vehicle. The mobile vehicle may be for example, a car or truck or other vehicle such as a balloon, dirigible, airship, ship, or boat. The vehicle has an on-board hydrogen generator for generating hydrogen gas, preferably using an electrolysis process. The hydrogen produced by the electrolysis process is stored in an on-board hydrogen storage tank. Hydrogen from the storage tank is flowed into a vehicle propulsion system where the hydrogen gas is consumed to provide power to propel the vehicle. An on-board electrical generation system provides at least some of the electricity for the electrolysis process. In one example, the vehicle has an on-board electrical generator for providing electricity for the electrolysis process. The on-board electric generation system may be, for example, a solar photovoltaic cell system, a wind turbine generator system, or a regenerative braking generator, for example.

Abstract: A system and method for generating hydrogen gas is described. The system uses a vessel for holding an electrolyte solution. A membrane is arranged in the vessel to form a chamber, and a cathode electrode is positioned in the chamber and in the electrolyte solution. An electric current is applied to the cathode, and with a cooperating anode, produces hydrogen gas using an electrolysis process. The membrane traps the hydrogen in the chamber, and assists in keeping the hydrogen separate from oxygen or other gasses. The hydrogen gas is exhausted from chamber for further refining, storage, or use.
