Hubble, the space elevator post:

xxx: to the ISS 400 kilometers, and to Peter 700. However, the ticket to the ISS is also more expensive.
To me here, Captain Evidence tells me that he read a textbook of physics for the 6th grade of high school and understood a little about potential and kinetic energy. To lift an object for 400 kilometers, you need to apply a little more energy than to move it for 700.
Yyy: No one guessed just taking a section of the railway and bending the rails up :)
Zzzz: No, it won’t work out. Snip 32-01-95
The limiting deviation shall not exceed for high-speed railways, high-speed railways and category I - 18 o/o, II - 20 o/o, III - 30 o/o, IV - 40 o/o.
