He is also talking about maintainance whose costs may eventually become higher than the original cost of construction and greater than the Annual income of the tower and thus making it a loss making business.

Well, I could just charge more then

Also a tower like the fordham spire which consists of uber-class apartments needs less lifts than an office tower of similar height

The tallest building ever designed is X-Seed 4000 in Tokyo, which is 4000m tall !

I honestly believe that we'll see buildings in the 2km+ range within the next 50 years. As we go through various the various environmental/economic crises that will be caused by oil scarcity, then global warming and the accompanying flooding crises in coastal cities (i.e. the majority of major cities), the economics of density will change, and people will be forced to be much more open to new ideas. Cars will become less efficient and cities will become more dense. Environmentally friendly cities will come to be seen as self-preservation rather than luxury, and highly controllable environments like X-Seed 4000 will start to look viable in economic terms.

Space elevators also have a better than 50/50 chance of getting started sometime in the next few decades. The whole reason to build them is that it's so expensive to maintain things in space. Space elevators are tremendously cheaper than rocket launches. Also, although they will be hit by rapidly moving debris, the current designs (and yes, current designs exist, using current technology for the fundamentals) use high-strength self-healing fabrics (like in fancy tires.) This also allows them to be supported by pressurization rather than a structural frame.

In the meantime, Burj Dubai is secure for the next 10-20 years. In the long run, the sky is no limit.

If a building is the inspiration of a government or civic affiliated companies and auspices where more then profit is a consideration then there will be little end to "go higher". If let to private developers then there is indeed a limit (though varying and hard to gage).

I do not believe that the space elevators will be there anytime soon. Not for a few centuries. Nobody has the resources and the technology to build them. Space elevators will be extremely expensive to construct. I think evetually the battle for the word's tallest building will end at around 3 km.

it's difficult to say where the limit is. I Think, if the Japan like they could build the XSeed 4000 without really big problems but if you'll build an tower which is thin like the burj dubai with an height of more than 2000m you'll get many problems.
look at the mountains, they're more than 8000m high but they're not thin, the're very very fat.

It's silly to say there's no limit, or until oxygen levels run low.

Are space elevators really skyscrapers? they're not buildings but they definately do touch the sky. Anyways i read an article int he economist that says that a space elevator is an idea that isn't that far away, they have determined that the most availible material for building the elevator is only about 4% of the required strength of the elevator, they have this carbon fiber stuff that is half as strong as it's required to be but too expensive. All in all the cost in the future should be somewhere at about 10 million dollars, not that much considering the costs of projects that NASA engages in.

Space elevators will not be built for hundreds of years if ever. By the time the technology is available to do so we will already have cheaper alternatives to reach earth orbit. I can't see buildings rising much higher than 1000m. There is simply no need for them, apart from forfilling the fantasy's of the kids on this forum.

Hey hey just a minute.

When some "mads" built Woolworth, Chrysler & ESB nobody considered them economically affordable. But look at them now: they're monuments of a recent past. Higher skyscraper spirit is not a short period economical business.

I think 1000m/3000ft is the actual "visions" reliable limit, and it will last for long.
