=WHERE TO=

==Major Challenges to Settling the Moon==
===Dayspan Heat - Nightspan Cold===
*The thermal problem as a superficial one in absence of a heat convecting atmosphere
:Shading joints, lubricated areas, material interface areas
:Development of cryo-lubricants
:Operations management issues
:Using materials with near-zero coefficient of thermal expansion
:Using materials that are both heat- and cold-hardy
===Dust Control Problems===
*Exploring electrostatic dust repulsion systems
*Turtle back spacesuits & conformal airlocks* (*also minimizes airlock cycling losses of oxygen, nitrogen, water vapor)
*Biodegradable suit and boot coverings
*Paving or sintering vehicle and pedestrian approaches to airlocks
*Covering joints and lubricated areas to minimize dust problem
===Power Options dayspan===
*Solar concentrators
*Solar panels
*Circum global solar powered supermagnetic belt
*Solar arrays distributing beamed power by relay sats
*L4, L5, L1, L2
*Lunar polar power tower global networks
*Nuclear
:Waste treatment
:Waste disposal
:Lunar nuclear fuels industry
:Scavenging nuclear wastes from Earth
:A lunar nuclear fuels industry based on the thorium 232 > uranium 233 cycle
===Power Options nightspan===
*Nuclear (see subcategories under Power Options Dayspan)
*Potentiation cycles - storing potential energy
:Water-oxygen fuel cells
:Flywheels
:Storage rings
:Hydroelectric loops
:Magma pools
:other
*Operations management
:Energy intensive dayspan tasks
:Energy-light nightspan tasks

==Site Type Pros & Cons==
===Polar Sites===
*Pros
:Both poles have "peaks of eternal sunshine" for power generation
:Thermal conditions do not vary greatly through the sunth (lunar month)
:Both poles are in the center of extensive coldtrap or permashade areas where we expect to find water-ice deposits
*Cons
:Both poles are rugged highland areas in which construction may be difficult
:The sunlight always comes in at, just above, or just below the horizon sibility and location identification problems
:The high amount of total tonnage needed to erect a solar power tower system
:Expected polar ice-deposits are of unknown quantity, concentration, and difficulty of extraction
:All our efforts mastering the challenges of the polar areas, will not prepare or enable us to set up outposts elsewhere on the Moon
:The polar highlands do not offer all the resources needed for industrialization
:Solar wind hydrogen, with which to make water, is available anywhere on the Moon
===Mare-Highland Coast sites===
*Locations of Interest
:[[Mare Anguis]]
*Pros
:Access to both major regolith suites
:Some coastal sites are also ilmenite rich
:Some coastal sites may involve potassium and phosphorus rich KREEP deposits
:Some coastal sites involve subsurface lavatubes
:Maria provide extensive areas of obstacle free transit
:Some coastal sites are much closer to the nearest circumpolar coldtraps, than either pole itself is to the nearest coast
:other
*Cons
:Extreme dayspan-nightspan temperature swings are a challenge to vehicle and structure design, as well as to lubricants
:The need to store up enough power during dayspan to get through the lunar nightspan
:Counterpoint: mastering these twin challenges will allow us to set up shop and settle anywhere on the Moon.
