TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Process: The process further comprises: igniting the elemental magnesium; passing the elemental magnesium into a conduit; passing the flue gas into the conduit; pre-treating the flue gas to remove the oxygen, by exposing the flue gas to silane, which reacts with the oxygen to yield silicon dioxide and water; and igniting and burning the elemental magnesium in the conduit to yield a mixture of heated gases and powders; transporting the mixture to a heat transfer chamber, where the heat from the mixture is used to generate energy; separating the gases from the powders; exposing the flue gas to amorphous silicon, which reacts with monatomic nitrogen in the flue gas to yield silicon nitride; and obtaining at least a magnesium oxide fraction (404) and a molecular carbon fraction from the burning step, where, after the burning step, the magnesium oxide fraction is further reacted with hydrogen iodide to obtain a magnesium iodide fraction (424), and the hydrogen iodide is obtained by contacting iodine with water. The magnesium iodide fraction is heated at 600-800 degrees C to obtain the elemental magnesium fraction (434) and an iodine fraction, where the elemental magnesium fraction is recycled to the burning step, and the iodine fraction is recycled and treated with water to obtain the hydrogen iodide. The molecular carbon fraction is utilized in a direct carbon fuel cell to generate electrical energy and a carbon dioxide fraction, which is recycled to the burning step. In the burning step: at least a first portion of the elemental magnesium reacts with at least a portion of the carbon dioxide to yield magnesium oxide, carbon, and UV light; at least a second portion of the elemental magnesium reacts with at least a portion of the carbon monoxide to yield magnesium oxide, carbon, and UV light; at least a third portion of the elemental magnesium reacts with at least a portion of the sulfur dioxide to yield magnesium oxide, UV light, and at least one of elemental sulfur or magnesium sulfide; at least a first portion of the nitrogen dioxide is exposed to the UV light and is decomposed into nitric oxide and monatomic oxygen; at least a second portion of the nitrogen dioxide and at least a portion of the nitric oxide are exposed to the UV light and are decomposed into monatomic nitrogen and monatomic oxygen, where at least a first portion of the monatomic oxygen reacts with a fourth portion of the elemental magnesium to produce magnesium oxide, and at least a first portion of the monatomic nitrogen reacts with a fifth portion of the elemental magnesium to produce magnesium nitride. The burning step further comprises exposing a solar cell to at least a portion of the UV light to generate electricity from the solar cell. The flue gas is generated from combustion of natural gas, and the process further comprises obtaining at least a magnesium oxide fraction, a molecular carbon fraction and a hydrogen gas fraction, where the molecular carbon fraction is: reacted with hydrogen gas in the presence of a catalyst (powdered nickel) to obtain a methane gas fraction; or oxidized to obtain a carbon dioxide fraction. The methane gas fraction is combusted to obtain thermal energy and a natural gas flue gas, where the natural gas flue gas is recycled back into the burning step.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The flue gas: comprises carbon dioxide, sulfur dioxide, carbon monoxide and nitrogen dioxide; and further comprises water vapor and oxygen, where at least a portion of the water vapor reacts with at least a sixth portion of the elemental magnesium to yield magnesium oxide and hydrogen gas. The elemental magnesium is in the form of a powder, rod and/or brick. EXAMPLE - No suitable example given.
