npub1jflcdvljl0n8hlz27798d0044rxwkqz69gapvcctt4p4gdt4kasqjgfmdd (npub1jfl…fmdd) How high would it have to be? 100km to “space”, but what application does a 100km space elevator have?
130 miles to be at the lower end of LEO and service the ISS.
1.2k miles to be at the top of LEO and service all things in LEO..
I’d say that since it facilitates easily bringing fuel to space putting it at the lower end is fine since now there is enough fuel for them to get to a higher orbit anyway. I found something saying that 10 miles is the max mountain height, but I think that was taking into account how fast mountain growth processes are vs. erosion, so I don’t think it applies to this project: we can probably go quite a bit higher.
Yea its hard to say how this might translate over to a man made structure though, thats the problem. I agree it seems like if you go wide enough the rocks can probably support 100km without basically liquefying and squishing outward? I think? But I think the crust will deform a ridiculous amount, so be sure to take that into account. :)
Yea it is both these effects im not sure about… I know if you dig even 1 mile down the pressures are so high that the walls of your tunney will slowly move like a liquid and close in unless you reinforce them… go too much deeper and even reinforcement doesnt work.
The depest we ever dug was 7.6 miles.. but im not sure if the limiting factor has any relationship to this…
