When will we have a 1 mile high skyscraper?

Just curious when it will be possible, if not yet, and what kind of footprint would it require?

i'm sure it's possible to built a mile high tower. from the engineering standpoint it might be possible, but no one feels the need to fund such a building

Ask Dubai
and possibly China/India

the West has already built their cities. The "east" or whatever you want to call it is finally building their cities.

I guess that would make it easier to enter the mile high club :)

At what height does the atmosphere and winds and other things make it unrealistic?

That tall of a skyscaper is just completely absurd in terms of cost to even consder nowadays. You would pretty much have to have the entire surface of the earth covered with people before that became viable. Instead if you wanted office space now and had that much money you could build 10 smaller buildings out in the suburbs and build an underground bullet train from the city to your complex. That way you would have the same advantage of being able to reach it quickly from the city, and it would probably still cost less. IF i am not mistaken, cost goes up by the square of the height, so a building like that would cost just obscene amounts of money.

When the moon starts bumping into you, there's a problem ;)

I imagine most huge skyscrapers are more about bragging rights and accomplishments than about space.... of course in some cases it matters, but in most your solution would obviously be way more efficient.

It would just be crazy to reach 1 mile high :)

the Federal Aviation Administration imposed a limit of 2,063 ft, based on this tower's height, on future construction; consequently, no taller structures may legally be built in the U.S. at present.


bummer :(

that tower in dubai is supposed to be as high as 3,000 feet so we are getting closer.

I suppose someone could pull a Freedom Tower and add a 5,200 foot spire on top of a McDonalds.

Actually, the biggest issue with building a skyscraper much taller than the current ones is elevators. You'd have to have so many of them to accommodate getting people to all of the floors that either the hole building is made up of elevator shafts, or you'd have to make the building wider than you otherwise would to make room for them. Neither is particularly feasible, so generally buildings aren't going to get much taller than they currently are, other than the jump of a story or two just to be considered the tallest.

Architecturally though, you could definitely do it.

We are not even close. I think it would be way too dangerous

I find it amazing that a building that is 75 years old is still #9 on that list. And #19 on the list was never finished. And there is no building on that list between 1933 and 1970. For about four decades, the top skyscraper list didn't change.

The elevators in the CN tower move at approximately 15 mph. It's pretty scary the first time you ever get in one because you really feel the G force as you accelerate straight up at to get to that speed.

One approach to fix the elevator issue is to have a multiple-tiered system. Many buildings already do this, where they have elevators that are split, based on what numbers of floors you wish to go to.

For example....a few elevators go to lower numbered floors....more elevators go to upper level floors....and eventually take you to a floor with a connection elevator to yet 2 more tiers of elevators to service the higher leveled floors. Express elevators can be available for a straight-shot to the upper floors. (preferred by CEOs)
