Space Colonization Options (Orbiting Stations, planets/moons)

You don't have to spend energy to spin.

The only energy that would be spent would be the energy put into building the Lagrange Point Hub.

The Lagrange Point Hub would be very similar to how a wind turbine operates. You have a central hub that is attached to vanes that are turned by the wind.

Gravity would function very similar. Since gravity is a body or force in motion and the vanes of the Lagrange Point Hun would be effected by gravity, the vanes would turn while the hub remained relatively motionless, save for the thrusters that would have to be used to keep the hub from wobble orbiting out of the Lagrange Point.

I'm certain politicians of the world will put having deal with the caldera off as long as possible in order to only save theirs elves.

Germany has already taken steps to ensure its power grid stays on by burying their powerlines underground.

Germany seems ideally suited to building the Lagrange Point Hun. But who will save the elves if not the politicians? Oh, the huge manatee!
 
Perhaps the following is a more "grounded" idea taken from the fusion thread, which I copy here:

Lest we forget, a space elevator could potentially be built using current technology from the Moon's surface to beyond the Earth-Moon L1 point.

(PDF) Lunar Space Elevators for CisLunar Transportation (researchgate.net)
Lunar space elevators could revolutionize the development of the Moon. The lunar space elevator system allows solar-powered robotic vehicles to climb a high-strength composite ribbon from the lunar surface to beyond the L1 Lagrangian point, where payloads of lunar resources could be released into Earth orbit for major space construction projects.

The overall system concept includes the lunar space elevator, a robotic construction system for the components, and robotic vehicles to carry lunar products into Earth orbit for construction and for upper stage propellant, and Earth-orbit payloads to the lunar surface for lunar habitat supplies. The construction system creates building blocks from lunar materials, using automated assembly and wire forming to construct complex shapes. The lunar space elevators provide non-rocket transportation of these lunar products from polar and equatorial mining sites into Earth orbit.

This architecture is a new way to create a lunar base for robotic and human operations on the surface. A lunar space elevator using existing high-strength composites with a lifting capacity of 2000 N at the base equipped with solar-powered capsules moving at 100 km/hour could lift 584,000 kg/yr of lunar material into high Earth orbit. Since launch costs twenty years from now may be $1,000/kg, this material would be worth half a billion dollars per year, creating a new era of space development.
In fact, Friedrich Zander first conceived of a lunar space tower in 1910. This idea was revived by Yuri Artsutanov in 1960, by James Cline in 1972 and by Jerome Pearson in 1978. More on the idea here:

(PDF) The Lunar Space Elevator (archive.org)
This paper examines lunar space elevators, a concept originated by the lead author, for lunar development. Lunar space elevators are flexible structures connecting the lunar surface with counterweights located beyond the L1 or L2 Lagrangian points in the Earth-moon system.

A lunar space elevator on the moon’s near side, balanced about the L1 Lagrangian point, could support robotic climbing vehicles to release lunar material into high Earth orbit.

A lunar space elevator on the moon’s far side, balanced about L2, could provide nearly continuous communication with an astronomical observatory on the moon’s far side, away from the optical and radio interference from the Earth.

Because of the lower mass of the moon, such lunar space elevators could be constructed of existing materials instead of carbon nanotubes, and would be much less massive than the Earth space elevator.

We review likely spots for development of lunar surface operations (south pole locations for water and continuous sunlight, and equatorial locations for lower delta-V), and examine the likely payload requirements for Earth-to-moon and moon-to-Earth transportation.

We then examine its capability to launch large amounts of lunar material into high Earth orbit, and do a top-level system analysis to evaluate the potential payoffs of lunar space elevators

The Moon is outside the Earth's magnetosphere most of the time, occasionally dipping into the magnetotail. The technique really depends on the solar wind so that's ok. Probably best to have four such tethers spaced equidistantly around the Moon's equator to allow for the Moon's changing orientation with respect to the interplanetary magnetic field and the solar wind. (At 1 AU, the IMF is at an angle of about 45° to the solar wind flowing radially outward from the Sun.) The main problem is the inherent diffraction pattern of a maser beam aimed at Earth, as the beam would have a large diameter after 380,000 km, depending on the diameter of the transmitter dish and the microwave radiation's wavelength. I supposed one way around this would be to use satellites to relay the power although a proportion of the energy would be lost at each stage.
 
Tethered statites above the Earth’s poles have quite the gravity well to fight…less so over the Moon’s poles…these could tack against the photon pressure (sunlight) while drawing off the solar wind…perhaps protecting Earth from CMEs at times.

Now…we think of the Moon as orbiting the Earth…but from the Sun’s perspective…we just get a little closer or farther…

Could tacking cables pass over and under our planetary poles….maybe doing a hand-off of some kind. I imagine the Moon with these huge whip antennae cables looking like a giant Sputnik I…half orrery…half tram cable…

I wonder if a nickel iron asteroid might be easier to move if most of its mass is extruded into wire…I can drag more weight than I can lift.

The same force with the same mass produces the same acceleration. You're describing moving a mass against friction as opposed to changing its potential in a gravitational field. Two different things, or if dragging an object via a path to the same gravitational potential, likely the elapsed time for dragging is longer than for lifting so the power required is reduced. Dragging will also expend more energy because of the friction.

One thing we haven't factored in with these generative tethers is that conductive objects moving through a magnetic field will feel deceleration due to eddy currents that produce magnetoresistive force. Interaction of their intrinsic magnetic field with the interplanetary magnetic field will also occur. These forces could easily destabilise the tethers if not compensated for.

The energy used to melt and extrude iron wire could have been used towards delta-v. Maybe the cable could be used as some kind of magsail, but dunno.
 
It could starwisp to Jupiter and sling back to the inner solar system…

A single device that both generates fuel and oxidant from water and, when a switch is flipped, converts the fuel and oxygen into electricity and water, has a host of benefits for terrestrial, space and military applications. From low environmental impact to high energy density, developing efficient unitized regenerative fuel cells, or URFCs as they are called, has been in researchers’ sights for years now.

What is highly unusual, however, is what a research team at TU Wien has now observed when studying hydrogen oxidation on a rhodium catalyst: The surface of a rhodium foil can be highly chemically active in some surface regions, while in others, only a few micrometers away, it is completely inactive, and still in others oscillations between the active and inactive state occur. Such behavior was previously thought to be almost inconceivable. The results, which have now been published in the scientific journal Nature Communications, show that catalysis is more complicated than previously thought.

"In some safety-critical scenarios, such as concerning the integrity of reactor containments, and metal vaults and bulkheads in maritime structures, it can be important to minimize the number of penetrations made through such metal structures for communications cabling. The use of neutrons for information transmission through such structures could negate the need for such penetrations and is perhaps also relevant to scenarios where limited transmissions are desirable in difficult circumstances, such as for emergency rescue operations."

A genetic breakthrough is on the horizon

By adding the genes necessary for transcription and translation to the artificial genomic DNA developed by the group, it could be possible to develop artificial cells that can grow autonomously simply by feeding them low-molecular-weight compounds such as amino acids and nucleotides, in the future. If such artificial cells can be created, we can expect that useful substances currently produced using living organisms (such as substances for drug development and food production) will become more stable and easier to control.

I don't think space elevators will be particularly useful. They're incredibly difficult and expensive to build and maintain. And I have yet to find anyone excited about riding in an elevator car with a few other people for 36000 km. Could the cost of such a thing ever bring it to the level of rockets? It seemed possible 20 years ago, but advances and simplifications in rockets, especially via SpaceX have changed that argument. Maybe in the farther future a rotorvator could be useful.

I haven't seen Foundation the series yet, so i don't know what their elevator looks like. Was it a carbon nanotube ribbon? I can see it causing some damage, but not necessarily anything horrific. The entire point of it being the mass of the ribbon is a small fraction of the counterpoise mass. (at about 60000km iirc) or that of the upper station at GEO.

For the moon, I don't know. The elevator would have fewer challenges like atmosphere, but more challenges requiring en-situ manufacturing. It would get around the problem of the moon's "lumpy" gravity profile that requires very careful and somewhat limited orbital options. Lunar orbital velocity is so low, however that a railgun (or even possibly a really good howitzer in vacuum) can put objects in orbit. The first SSTO rocket was not earth bound, it was the LEM's ascent stage. So, I am uncertain again there would ever be demand for it.
