TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The anode and cathode (14) structures comprise an electrolyte gel. A gap remains between these 2 structures. A water-based gel is provided at the gap. The rigid structure contains apertures for ionic communication between active material of the anode structure and hydroxide ions generated at the cathode structure. It comprises plastic coated metal honeycomb mesh having an open ratio of 70-90, preferably 78%. An electrolyte is embedded in the anode structure. The anode structure includes a tube having inlet and outlet. A bimodal gelling formulation is used to promote even distribution of electrolyte gel within the anode structure. The cathode structure includes air frames positioned adjacent an active cathode portion for assisting in distributed air flow across the surface of the active cathode portion.Preferred Materials: The rigid materials consist of plastic, plastic-coated metal, ceramics, and/or non-conductive or carbon composites. The gelling formulation comprises a first type gelling agent for providing a matrix having low viscosity with matrix structure to allow dispersion of a second type gelling agent for providing a desired viscosity of the gelled solution and is prevented from settling or forming undesirable dense chunks or globs during gelling.    TECHNOLOGY FOCUS - POLYMERS - Preferred Materials: The rigid materials consist of plastic, plastic-coated metal, ceramics, and/or non-conductive or carbon composites. It comprises plastic coated metal honeycomb mesh having an open ratio of 70-90, preferably 78%. The first gelling agent is consists of cellulose fiber, alpha-fiber, and/or microcrystalline cellulose. The second gelling agent is consists of crosslinked polyacrylic acid, potassium and sodium salts of polyacrylic acid, carboxymethyl cellulose, hydroxypropyl methyl cellulose, gelatin, polyvinyl alcohol, poly(ethylene oxide), and/or polybutylvinyl alcohol.    TECHNOLOGY FOCUS - METALLURGY - Preferred Materials: The anode structure includes a metal constituent consisting of zinc, calcium, lithium, magnesium, ferrous metals, aluminum, their oxides, and/or their alloys. The metal constituent is mixed or alloyed with constituents consisting of bismuth, calcium, magnesium, aluminum, indium, lead, mercury, gallium, tin, cadmium, germanium, antimony, selenium, thallium, and/or their oxide. The anode structure is formed of metal constituents consisting of powder, fibers, dust, granules, flakes, needles, or pellets, preferably of fibrous metal constituent.
