yeah right ... if all the nasa dreams/plans would be realistic, we would have had a permanent base on the moon back in 1991 ... Look how hard it is to keep that spacecenter running, i think we'll sooner see that thing drop in orbit than we'll ever see anything human bigger than a house in space again

Uh no! Do you even know how long that would take to construct? Oh, only about 50 years! Also, were you too stupid to realise that there are bits of space junk that fly past earth at around 30, 000 kilometres per hour? Your "space elevators" would not even last an hour in space. And anyway, if you were to attach it to a meteor, it would be invulporised by the sheer speed of the meteor itself.

The tallest structure in the world will be the Enviromission Solar Tower, which will be built in AUSTRALIA!

Dubai will sure have the world's tallest if they can successfully build The Burj.

The military owns the airspace above a certain height, so there is technically a limit to how tall skyscrapers can be.

With that in mind, there is no place else better than Chicago!

I think it would kind of be kool to build really tall skyscrapers next to really tall clifs then supports could be put in the side of the clif like start at the bottem on the grand canyon and some of them are like a mile high

Actually a 500m building is not economically viable. I heard somewhere that a building becomes not eco viable around 300m.

That's what I was thinking when they started announcing all this megatowers liek the Burj and FS. They must have found a way to make the money needed to support this megatowers or else they are doomed projects so why would they build them? Something's fishy :P

Yeah, like Detroit, New Jersey, Bronx and favella style LA neighbourhoods are exactly what a "first world" country is all about.

It depends on loads of things. If I were to build a 700m tower with 1000 apartments each going for 5 million then it would be no problem.
