Getting to space is incredibly hard, expensive and needs a lot of resources.
A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space.

    Probably wont happen in less than yo, this require extreme calculus, consideration of so many factor, without real efficient quantum computer this is not a good solution and even when the tech get there you need the program, the ai, so much preparation, its just not practical, the space elevator already is much less fiction compared to this, since it is going nowhere, I just suspect that this is an idea that you personally like and wanted to give credit to and this is not objective.

    Imagine the CONSTANT calculations having to be done to accommodate this. Shuttles latching on to the hook, automatically rotating the momentum of the hook with engines.

    This'll end up being something like the oil industry in that it'll be difficult to shift away from it to something better once the technology is readily available. There will then be hundreds of whirling cables swinging around the earth (I doubt, by the time we come up with something better, we'll have gone further than Mars) that will require synchronicity with all nearby satellites and shuttles. It's a quick and cheap solution but I think it is not a long-term one - hence my comparison to the oil industry (which is now obsolete - for energy, anyway). My goodness that is some primitive technology. Look up the "atlatl" an ancient javelin which utilizes the same physics trick. I hope someone figures out a better idea before somebody actually tries this. The soundtrack on this video is awesome.

    Correct me if I'm wrong but to keep the thing going there needs to be ships coming in right ? If the tether is built spinning so that it's moves slower when closer to earth and faster when further from the earth wouldn't it be hard for ships coming in to lock on to it ? English is not my first language so i apologize for any spelling and grammatical mistakes or that something isn't clear. Thank you

    Stuff like this is theoretically possible. With an emphasis on "theoretically". I'm sceptical of the claim that the materials exist that are tough enough to make the cable from - the current construction materials can't even support their *own* weight over such distances, let alone the weight of a massive rocket, let alone a massive rocket which is also being accelerated to escape velocity and back down again. Humanity may be doing this sort of stuff one day, but almost certainly not within any of our lifetimes. I genuinely think that cold fusion is a more credible way of solving the fuel-payload problem.

    Making a hypersonic high altitude vehicel is hard, but its also something we've done so in theory the hook part of the sky hook is feasible, but how do you get the tether to survive hypersonic reentry (if only partial reentry into the exosphere) over and over and over again?
