TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred System: The system further has a discharge housing, an osmotic controller, pH-sensors (I,II), a power source of solar, geothermal, hydro, hydrocarbon and/or wind-based energy generator to generate electricity for powering the electrolysis of the electrolyzer, a tower, a wind-turbine, and a reservoir. The discharge housing receives solution discharged from the osmotic exchanger. The discharge housing comprises a dehydrator to dehydrate the discharged solution to produce dehydrated product of metal carbonate/bicarbonate for external release and handling. The discharge housing is operatively configured to enable external release of at least a portion of the solution received. The osmotic controller is operatively configured to influence the flow of the ambient atmosphere in fluid communication with the external surfaces of the permeable walls, a ratio of the metal hydroxide to water in the solution fed into the osmotic exchanger and the rate of discharge from the osmotic exchanger based upon at least one of the concentration of metal carbonate and/or the concentration of metal bicarbonate in the solution discharged from the osmotic exchanger. The pH-sensor (I) determines a pH level of an external component of water, where the osmotic controller is further operatively configured to base the influence a portion on the pH level determined. The pH-sensor (II) determines a pH level of the solution discharged, where the osmotic controller is operatively configured to enable release of the solution from the discharge housing when it has pH higher than the pH determined for the external component of water. The wind-turbine is supported by the tower to generate electricity, where at least a portion of the electricity generated is available to power the electrolyzer, and the permeable wall define a gas-to-liquid transfer network of the osmotic exchanger that is supported and extends along at least a partial height of the tower. The reservoir receives water and metal hydroxide from the electrolyzer for the solution, the reservoir supplies the solution to the gas-to-liquid transfer network of the osmotic exchanger under the influence of pump(s) and gravitational forces. Preferred Material: The permeable wall of the osmotic exchanger comprises micro-, meso- and/or macro-porous membrane material. The membrane material comprises GORE-TEX (RTM: hydrophobic, micro-porous material). The osmotic exchanger further has hydrophilic material disposed within an interior of the osmotic exchanger between inwardly facing surfaces of the permeable wall. The hydrophilic material is operatively disposed therein for increasing an effective surface area of the solution flow for absorbing the carbon dioxide.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: A carbon dioxide sequestering method of fuel synthesis involves producing hydrogen by electrolysis of saltwater/brine, sequestering carbon dioxide with metal hydroxide byproduct resulting from electrolysis of saltwater, reacting nitrogen with hydrogen produced from electrolysis to produce ammonia, reacting ammonia with carbon dioxide to produce urea, and reacting urea with ammonia to produce guanidine. The electrolysis process further produces hydrochloric acid.
