I don't know where to look for it anymore. It was someone's joke, there's just no way, even theoretically, to make a pipe 400-600km high.
A body moving on the surface of the Earth at 8 km/sec weighs nothing. Electrons in a kinescope, for example, don't weigh anything either.
And if you make a big current...
If you accelerate it to the second cosmic speed, will it fly into space?
If accelerated to second space speed, will it fly off into space?
what about a pyramid? like rings of 10 km in diameter.... narrowing slightly in diameter and increasing in height.....
...
And, if you make a big current ...
The catch is whether it is possible to get a geostationary satellite at the altitude the ISS is at. I don't know.
There doesn't seem to be a catch. Regardless of the speed of the earth we have a boundary zone distribution ( doesn't fall away) depending on mass
Now by adding the speed of the satellite's rotation around the earth, it is possible to reduce the distance to earth by increasing the velocity and considering the mass
well - a 15-20 km high pyramid is enough to make a pyramid.... there will be less air resistance, the missiles will take out more cargo by an order of magnitude....
The ISS rotates at 16 revolutions per day around the Earth. How can it not fall if it rotates at 1 revolution?
We need to increase the orbit
Look at the solar system
The complete set. Different masses, different orbits, different speeds. Those closer to the sun tend to rotate faster, but given the masses.
