Not my decision, but at the moment, with the current state of technology, they do fade.

As you say, you would need a lot of batteries. Flywheels brought from Earth would by a similar mass, but they would last far longer. And...

True. My main argument is that batteries fade over time, but a flywheel won't.

Indeed. Perhaps I shouldn't have added that to the proposal, it just complicates things. I do think it is possible that basalt fiber...

Yes, and while real examples of both vary, a flywheel without the mass of a vacuum container is broadly similar to battery. But with the...

For controlling robots on the Moon, for mining or construction. We have robots that can copy human movements from camera vision...

If making basalt fiber on the moon presents problems, then I propose making the flywheel on Earth. For a energy storage solution, I am...

Batteries bad The article linked above says batteries are problematic in space. I propose a flywheel, which is suited to the Lunar...

I think you may be referring to the nausea that is caused by turning your head in a small radius rotating environment. But these...

"ultimate deep freeze at about -100°C." yes but insulation is much easier in vacuum, and so is arranging to expose it to sunlight.

Why hollow out - the reason is delta-V. Why not find mass that is already moving where you want it to. And why rotate them? - find ones...

That sounds comfortable. If I were living that far from home, I'd want comfort. And at least 6 meters of radiation shielding.

Yeah, but they just talk about unicorns. Oops, I didn't mean to end the thread. I like to talk about things that actually could be...

One of them is a near-Earth object. The rest are in the asteroid belt. The asteroid belt could be a source of zero-g materials to an...

TL;DR: Fast rotating asteroids could be rotating habitats Fast rotating asteroids The rotation is so fast that if there were internal...
