A proposal to erect high altitude towers by using the Stonehenge builders technique of letting gravity do the work:

How to raise a tower to space? The ancient Stonehenge builders may have had
the right idea. And applications. https://exoscientist.blogspot.com/…/how-to-raise-tower-to-s…

The nice thing about this approach is that it allows an incremental approach
to testing rather than jumping immediately to a ca. 100 km high tower. In
fact, just a 10 km high tower would be important for generating power from
the jet stream. Once that is successful, that would give greater credence to the idea a 100 km high tower would be possible.

Actually, the much easier 10 km tower might turn out to be the far more important one since it would provide a high energy source of power: a single jet stream wind turbine could supply 1 GW of power, enough for a city of 1 million people.

For a couple of seconds until it disintegrates.

Sorry. That link was garbled it should be as below:

how are you going to get a 1GW generator upon the top of a 10 km tower ?

how much does a 1GW generator weigh ?

wind loading is the amount of side pressure by the wind on your tower,
how much should it be in the jet stream ?

How wide is the base of your tower in km? (you have weight of generator,
and wind loading)
