NOVELTY - The apparatus comprises first and second electric field sources, an insulation layer to electrically isolate the first field sources from the water, a first conductive deionization surface within a field line of the first field source, an electric conductor connected to the first deionization surface and adapted to discharge charge built up due to attracted ions at the first deionization surface, a second conductive deionization surface, an electric power source adapted to charge the first field source, and a switching circuit adapted to connect the power source to the field source.    USE - The apparatus is useful for producing hydrogen gas from water.    ADVANTAGE - The apparatus economically produces hydrogen gas from water with high resistance and electric energy and minimal leakage and without dismantling, and maintains the water at a predefined temperature or range of temperatures.    DETAILED DESCRIPTION - The apparatus comprises first and second electric field sources, an insulation layer to electrically isolate the first field sources from the water, a first conductive deionization surface within a field line of the first field source, an electric conductor connected to the first deionization surface and adapted to discharge charge built up due to attracted ions at the first deionization surface, a second conductive deionization surface, an electric power source adapted to charge the first field source, a switching circuit adapted to connect the power source to the field source, and a field shielding structure adapted to shield the electric conductor from electric fields. The first and second deionization surfaces are electrically connected. The switching circuit includes a diode. The field shielding structure is grounded. The deionization surface is grounded through a ground switch, which is adapted to oscillate. An INDEPENDENT CLAIM is included for a method of producing hydrogen gas from water.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of single pair of field sources to produce hydrogen from water.
