Oh no.....PCU limit reached.
Well, it was always optimistic right from the start.
Tunnel through the Earth Planet and float at zero G at the core. Tick
Construct a multi-head drill to all in Auto collect a serious amount of ice, construct a conveyor >2km long to take it back to base. Tick. No problem.
Next. Build the holy grail.
Space elevator. ~41km vertical.
Build it in space and lower it to ground. Where to built it? Easy. GPS mark the point to land. Calculate a marker from 0;0;0 through the target marker up to 42km AGL. Calculate an alignment marker another 2km out and use those as starting points and alignment so the whole thing is gravity aligned.
No challenge.
Advantage of building in space? All the raws you need and you aren't fighting gravity for 41km.
Right. Built it to 3km with a hydrogen powered reverse thrust braking mechanism at the tail end and nose down a cab with landing legs. Beautiful.
Test the principle. GREAT. IT WORKS.
Now, build to 6km length and test. Again success. The braking mechanism sliws it down from 104m/s to 0 in 210m. Smiles all atound.
Go to 12km and test. We are now getting really serious. Very nervous but here we go. Again success.
With reduced gravity at altitude from 12 onwards you can stretch the reverse thruster station. We'l go to 20km and do the next check. That is almost halfway 🤭🤭🤭
And then, at 16km conveyor lenght, this...😵😵🥴🥴🥴😳😳😳🤬🤬🤬🤬🤬🤬😩😩😩😡😡😡
🤷♂️ oh well, ...next project.
