It spins to provide artificial gravity.
Spinning could be done with thrusters and then sustained by polarising the station to be spun by earths magnetic field.
Stable? Who knows, but I'm sure some nerd will figure it out.

The earth is flat and stationary with a dome. You are never ever leaving this enclosed plane alive and you will most definitely never jet through the galaxy in your rotating wheelstation. You'll have to do with CGI, possibly streamed straight into your vaxxed brain.

>> No.15438226

>>15438204
I know the purpose of the spinning, but I'm questioning the logistics.
If they start it spinning during construction, stability/wobble would be a nightmare. If they wait till after construction it would take incredible amounts of energy as well as time to get it to spin (and again, the nightmare of stability).
Looks cool for sci-fi, but practicality-wise a pipe-dream.

So the outer structure also has to withstand the near constant force of the thrusters anchored to it. How many centuries of operating and refueling these thrusters do you suppose it would take to finally get it rotating at sufficient speed?

Eh it depends, without lend lease I doubt the soviets would have had the same scale of industry that they had late war, plus if both the US and the British stayed out for whatever reason it would be a one front war, freeing up 2 other fronts' worth of manpower and logistics. It'd still be close though because Russia is fuck off huge but most of the important parts are in Europe

Without lend-lease, without the second front, Germans would have brilliantly adapted even better than they did--high tech weapons, all kinds of breakthroughs like petrol from coal. And Russians were coming for them anyway. No Ameri-golem, and they had a smart puncher's chance.
And then we might have had this kind of future in space. Well at least the best race would have had it.

What for? Every profitable thing we know how to do in space requires microgravity. Building a station specifically to defeat microgravity also defeats the purpose of being in space.

Now, on a vehicle, sure. Then the purpose is clear, to keep astronauts' bodies from falling apart on long journeys around the solar system. But there won't be a case for stationary spin habitats until we've got such abundant lunar resource processing and robot labor that we can start thinking about building o'neill cylinders as permanent human population centers.

We probably aren't gonna live to see that. In our lifetime it'll all be tiny 2-4 man commercial LEO nanofabrication and specialized medical labs, which not only don't need to spin, they specifically need not to
