1. A method for reducing a carbon-containing gas content of an input gas mixture, the method comprising steps of:
(a) providing a molten electrolyte media in fluid communication with a source of the input gas mixture, the molten electrolyte media having an affinity for carbon within a carbon-containing gas of the input gas mixture;
(b) positioning a thermal insulator between the molten electrolyte media and a source of the input gas mixture, wherein the thermal insulator allows a net passage of the carbon-containing gas from the source through a first layer of the thermal insulator that is adjacent to the input gas mixture and through a second layer of the thermal insulator that is adjacent to the molten electrolyte media;
(c) establishing a temperature differential whereby the molten electrolyte media has a greater temperature than the input gas mixture; and
(d) reacting the molten electrolyte media and the carbon-containing gas together so that the molten electrolyte media acts as a carbon sink for reducing the carbon-containing gas content of the input gas mixture,
wherein the molten electrolyte media defines a surface with an upper surface area and wherein the upper surface is in fluid communication with the source of the input gas mixture.
