>> id like to see some calculation
I can just pull some numbers out of my ass for this one, but they won't necessarily make any sense. You can cheat a bit though by boiling water to get rid of heat. Although I'm starting to realize that hey you need a decent amount of surface area for lift and that the rocks you're picking up are indeed still hot, so maybe it doesn't work out. There are high temperature polymers that work at these temperatures, but experience degradation over long time periods:

These have even been used in plastic engines:

>>cargo you mined god knows how
I will admit this is insane, but I was thinking of just dredging shit up. Fly near the ground and slow, which you can do cause the atmosphere is fucking dense, deploy a dredge and pick it up once it's full of rocks. Otherwise, we can just mine with remotely controlled robots using silicon carbide electronics..
>>It's not a fucking space elevator.
you need a tether an order of magnitude longer than anything we've ever built. Longest tether I can find is 3 km:

Wikipedia does say that there are high end carbon fibers with breaking lengths 250-399 km long.

God knows if they work at these temperatures though.
>>you're fucked as soon as you wind up on the night side
The atmosphere still rotates on the night side, so you just need some batteries or fuel cells. So again, you get a day night cycle close to 4 days if you don't fight the wind
>>fighting the extremely slow rotation with engines wouldn't be so bad
so you have a giant fucking tank at the end of your tether? That's fucking nutty.
>>fighting the wind
which is why you don't fight it.
