An electrolytic solution generator includes an electrolyzing unit having a stacked structure in which a conductive film is interpose between a cathode and an anode, the electrolyzing unit electrolyzing a liquid, and a housing in which the electrolyzing unit is placed. A channel is disposed in the housing, and a groove is disposed in the electrolyzing unit, as a groove which is open to the channel and to which at least a part of an interface between the conductive film and the cathode and an interface between the conductive film and the anode is exposed. A space is disposed between at least either an outer periphery of the cathode or an outer periphery of the anode and an inner surface of the housing.

A system to generate gases from a liquid or a solid source including a generator, a dual arbitrary generator, a turbine, a thermoelectric generator, a pulse-width modulation device, a suction pump, a radiolytic cell, and magnets. The radiolytic cell includes a body, a first disk, a second disk having a plurality of perforations, and a plurality of radiotrodes. Each radiotrodes includes a large diameter tube, a small diameter tube concentric with the large diameter tube, and metallic wires having an end fixed into an upper section of the large and small diameter tubes and to lower sections of the large and small diameter tubes. The second ends of each one of the metallic wires are connected into the perforations of the corresponding first disk or second disk. The radiotrodes hang up inside the electrolytic cells by the metallic wires producing movement or vibration of the radiotrodes inside the radiolytic cell.

A desalination battery includes a first electrode, a second electrode, an intercalation compound contained in the first electrode, a container configured to contain a saline water solution, and a power source. The intercalation compound includes at least one of a metal oxide, a metalloid oxide, a metal oxychloride, a metalloid oxychloride, and a hydrate thereof with each having a ternary or higher order. The first and second electrodes are configured to be arranged in fluid communication with the saline water solution. The power source is configured to supply electric current to the first and second electrodes in different operating states to induce a reversible intercalation reaction within the intercalation compound. The intercalation compound reversibly stores and releases target anions from the saline water solution to generate a fresh water solution in one operating state and a wastewater solution in another operating state.

A method and system for electrolysis. The system includes a system and method for separately collecting hydrogen and oxygen gases produced by a plurality of anode and cathode plates, one of the anode or cathode plates surrounded by an envelope penetrable by an electrolyte solution and impervious to hydrogen and oxygen gas. The system includes an electrolytic cell which has a front end and a back end. The front end has a cathode electrode coupled to a cathode screw, and an anode electrode coupled to an anode screw. The screws are coupled to a spacer, which is coupled to an insert. Each insert is further coupled to a second insert. The coupling results in the plate being conductive. The plates each have at least two holes, a large hole and a small hole. The small hole makes contact with a spacer and/or an insert.
