-==Methods of LUNOX Production==
+==Lunar Production and Use==
-Most of the methods of lunar oxygen production envision the [[reduction]] of lunar [[regolith]] or rocks to liberate oxygen, although another possible method of harvesting oxygen is to free small amounts of trapped gas from soil by heating.  Reduction methods include:
+Oxygen production from lunar sources (sometimes referred to as '''LUNOX''') is a critical element of any plan involving long term human presence on Luna. Oxygen is required for both life support and rocket fuel, and as such would be needed in large quantities. Lunar Oxygen production is one category of [[In Situ Resource Utilization]](''ISRU'').

-In lunar oxygen production, it is necessary that the net reactions be limited to the planned raw materials being converted to oxygen and the planned tailings.  Catalysts and other reactants must be returned to their initial states as much as is possible.

 From review by Arthur Smith on ADB:   "In particular Appendix E's coverage of oxygen extraction is extremely thorough, and the authors, while finding it somewhat difficult to directly compare techniques, find 4 of the approaches worthy of considerable further research: hydrogen reduction of glass, magma electrolysis, sulfuric acid dissolution/electrolysis, and ion sputtering."
