Alright, we had a return of certain poster on half chan that dropped good amount of info from a different perspective during 2016-2017.
Everyone has heard of the high level insider aka HLI, with past compiled posts here:

Last night he seemed to have made a return albeit without the namefagging. It was in the newly revived Space Elevator General thread and he answered some questions before just going silent for a bit and there was excitement in the air in either direction.

In the spirit of optimism and renewed hope, I decided to start an ongoing /SEG/ aka Space Elevator General to encourage other people to not only consider the negative but also a positive way forward, and meme some good things into existence, because we know this administration is watching all these boards like a mother fucker.
Introduction to the topic:
It is already possible to build a space elevator. The key idea is the Orbital Ring version of the space elevator, not the geosynchronous tether concept you are familiar with.
See, for example, Paul Birch's writings:

There are many other feasible ways for us to get to space much more cheaply and safely than rockets:

You get the idea. Any of these could be done for $100 billion or less, a negligible cost when considering a GDP of trillions of dollars.
Why do something like this? Overnight, asteroid mining becomes an incredibly profitable industry. Because the cost of delivering payloads to LEO drops from thousands of dollars per kilogram to less than $100 (potentially less than $1) we can now retrieve asteroids with trillions of dollars worth of minerals for mere tens millions of dollars in addition to having an easy viable way of returning those resources back to the surface. We acquire the ability to deploy profitable solar power in orbit above cloud cover and with the ability to return said power back to the surface with near zero loss by running power transmission cables down the elevator.
