The resources, techniques, and purposes to which lunar materials could be put are discussed, with attention given to transporting lunar materials to cislunar space for the construction of space manufacturing and habitable facilities. A model molecule, demandite, which represents the mole fraction of all materials used in the U.S. in 1967, is used to assess the lunar resources defined during Apollo missions. It is shown that duplication of the same manufacturing, fuel, and life-support systems in space as those on earth would cost several orders of magnitude more if the materials originated on earth than on the moon. The demandite would be sent into cislunar orbit using linear electric motors. Lunar surface concentrations of pyroxenes, olivine, feldspars, ilmenite, basalts, anorthostatic rocks, and breccias are reviewed, noting that carbon in the regolith is solar-wind derived, while in lunar rocks the carbon is indigenous. Lunar mining techniques are envisioned, especially the capacity to move large masses at 1/6 the effort required on the earth.
