I've had this dream, where the elevator just keeps going up, enough said.

Elevator to space, the structure would be deeply rooted underground, never fall, never bend, titanium alloy, completed through 3D printing. On top of mountains.

You sure do have weird dreams

Theoretically possible, but instead of a tower it uses a satellite in geosynchronous orbit as the anchor. The tricky bit is getting a cable light yet strong enough to not break under its own weight. Last I remember they were looking at carbon nanotubes as the base for it...

True, I too looked into carbon nanotube, but even with the strength of steel it is still not good enough to handle the pressure. Right, even titanium alloy at that height could bend, maybe a different type of structure is needed, like a pyramid.

Only issue with your dream is titanium while being very strong is a bit brittle. I would be concerned with it snapping in prolonged sub zero temperatures of space. The other issue your going to face is where to place it(tornado, hurricane, large earthquake are all issues) and how your going to keep air traffic away from it. I suppose if it was an international project(cheaper to ship goods up an elevator) you could designate it a no fly zone. Also you'd need to make the structure larger then needed. With an elevation going into space its prime for cell towers, other instrumentation.

Though I do agree a Geo-synchronized satellite would be an ideal anchor though you'd have to come up with some sort of space defense system. Not against humans but rather meteorites, ect. Having a 4mile high structure fall to earth because it got hit with a pebble going 10,000mph would be a real kill joy. Perhaps building the structure a bit like the eiffel tower would work? Triangles are the strongest shape in normal gravity. Would add a bit to materials list but I think it would be safer in the long run.

I dont think I'd want to be stuck in a tiny metal box with 5 other people for 30 hours

This reminds me of Kaiba's elevator to space in Yu-Gi-Oh!: The Dark Side of Dimensions.

Top grade steels are actually stronger than titanium alloy. What titanium has going for it is that it is has a high weight to strength ratio. As for your space elevator carbon nano tubes are the only current material coming close to having the necessary tensile strength while still being extremely light for the project. Problem is carbon nano tubes production is extremely limited.

Better be careful of your design; a guy from Croatia has already claimed a patent for some of the concepts http://www.zadar.net/space-elevator/. I have no idea which jurisdiction the patent was filed in or even if it is valid.

My only concern is how do you actually go back to earth...

With 96 hours of elevator music.

(And that one idiot who keeps turning to the side and back to see if everyone else in the elevator will automatically do it...)

I would saying falling
But that doesn't really work in space

Ideally an elevator goes both ways, you know?
