Engineers universally agree that the Chrysler Bulding and the ESB would have survived a commercial jetliner. Because they're predominately stone-mason, and not utlra-modern flammable materials. So not only were the Towers a more symbolic target, they were literally weaker buldings.i guess you can build as tall as you want,

i think the highest will be less than 2000m..if more,then it will be less practical

The higher you build, the thicker the base has to get to withstand all the mass on top of it.
That will produce very deep floorplans where the sunlight will never touch the ground.
What rooms shall be in such floor plans and who shall work or live there?

Burj Khalifa is a very elegant solution for that problem through its 3-winged-design of a floorplan
but that can not be extended endlessly.

At very high altitudes also the air itself gets less dense, so there will probably never be a skyscraper taller than Mt. Everest

I think there will be a lot of ~1 km buildings in the not too distant future, but probably very few of well over 2 km.

technical innovations will give us taller and taller buildings and since it will never stop to be a sign of prestige, people will always want to have the tallest, so they will try to trumpf each other again and again.

Will we have the same soft of ethic issues when people starts to print a puppy.
Printing a living thing is a BIG step further (if not impossible. Cloning and growing a puppy is more logical) than printing an apple. An apple, or a steak, is basically just the same cells stacked on top of each other and they already have printers that can print layers of human skin. It would solve some huge problems in the world if we could print a steak, but that's another discussion.

Advance in material science will help a bit, but there will be a limit.

A huge footprint will be kind of defeat the purpose as it is the lack of space at the first place.

Burj Khalifa is all about pride then need, Dubai or even the whole of UAE doesn't need it.

It is much cheaper and less risky to build 2x 600m then 1x 1000m tower.

I really want to see (if I am still alive) to see how technology progress to print organic materials, what base materials do you need, etc. Printing apple, steak is not as trival as "same cells stacked on top of each other".

Skins or other organs contains genetic informations and printing those will probably be as complicated as cloning.

I wonder if someday we could grow buildings and skyscrapers like "super trees" using genetically reassigned protein 'building blocks' that enable the organism to rapidly shoot out of the ground, absorb huge amounts of CO2 and grow to enormous heights with a hollow core that can be fitted out for dwellings and other uses. I wouldn't imagine such an organism growing to megatall height but it would be cool to grow structures that could replace conventional high rises that would require increasingly scarce materials.

Also, we could develop strong, lightweight new materials using bioscience to enable extremely tall structures to be built more cheaply and sustainably.

I think the physical limit for it based off of how high a human can with stand do to air and air pressure is 4000 meters in that the Andes Mountains and Rockies are around that tall above sea level and they have people living on them. So if we look at it that way people should be able to live in a 4000 meter skyscraper.

If there's one thing that we must learn (more like unwillingly accept) is that we have NO limitations, other than what technologies we can afford at each stage of development.

Imagine the face of a caveman that would had traveled to today's time and landed in midtown Manhattan or God forbid! On the front door to the Burj Khalifa in Dubai?

Limitations are only a temporary thing for humanity. A mere pothole in the road.

Can we build them 2 miles and up? Can we reach the limits of our own atmosphere? These are not questions, but simple problems that can be dealt with with time.

Would there be any usable need to live at such high places? Can you go back in time to the 1800's and make the same question? Or better yet! Why not go back in time to when we all lived in communal homes!

The driven factor is not development for the sake of reaching new altitudes, but driven by needs our present heights can't fulfill 100%.

Why go up? $$$! Space is equal to $$$ and the more that space goes up in value and scarcity, the higher we'll be seeking the skies above us.

We have already reached the point where "air values" have been preset in highly congested and supra developed cities. The next limit, of course, would be space.

The question is not how tall can we build, but how soon will the next altitude records be reached in our generation.

The TV set was not created after the programming, but the contents followed the invention. If it can be made to be habitable, by any means of technological advances, then it will be populated for sure. That's the lesson we take from our long history and development.

If you take a look at what we have today for basics in our tallest residential buildings (or mixed use if you will), you'll find that things as old as plumbing for water needs and sewage are included.

Given the advances we have reached so far and will surely step onto in the next generations, it's safe to say that plumbing won't be a factor in future buildings at all. We can, today, make water from other particles. It's safe to say that the same trend will also make it viable to take apart when it's not needed, or after use. It's not only viable, but done today in space!

The number of things that can and will change, are only limited by our imagination.

Again, take the Burj Khalifa concept and go back in time to the Empire State building's next day inauguration. See how such idea would had seemed out of the Milky Way then... And yet, today that same outlandish concept is very real to all of us!


If you had the resources today to place the best and most innovating minds of today's world in the same room, give them a concept to build not only a space elevator but a functional space elevator spacescraper whilst at it. Not only will you have the blue prints for such outlandish concept within our generation, but so many innovations and world setting inventions to boot, that the future of development would take a giant leap for the engineering mankind.

I believe that mankind is bound to reach a technological advanced that in the future, we'll be able to engineer and design an entire man-made planet from the other celestial bodies. A man-made planet will not only be more stable and purpose-built than what we have now, but made to order to our very needs as an species.

We soar in the skies above us and beyond the limits or our own planet. We dive in the deepest waters of our seas. We can probe the inner core of our own Earth. We populate the most inhospitable and barren sites in our crust's surface.

All this was achieved and being achieved as technology, innovation and inventions, answer each riddle we come across in our quest to push the boundaries of said limitations.

The only limitation know to be a major problem to surpass for us a men, lies in our mortality. And even that's the subject of intense research today and ever since we took upon that bump in our road.

Maybe for a man of today the physical limits to withstand altitude and air pressure is low. But for a possible man of tomorrow with a technological enhanced body, that would be the same trial our present amputees faced in order times.

We have a little discussion about office vs telecommuting 6 months ago, today, we see some company want to reverse it.

http://www.smh.com.au/it-pro/busines...225-2f10u.html

Quote:
With Yahoo and Google sledging teleworking as slow and detrimental to work quality and creativity, has working from home lost its lustre?

Yahoo's head of human resources Jackie Reses sent out a memo on Friday telling remote staff they must be working in the office by June and if they had an issue they could quit.

Is this the end to what Deloitte said would be one of the biggest structural changes to the Australian labour market this decade?

If made on the equator exactly the centrifical force of the rotation of the earth could keep it up and it may even be stretched sure it might cost a few hundred billion bucks and holes be needed for satellites but possible with the money.

With respect to high of building tall limit depend on new theory of discover technology that appears in each time
And I think any roles of tall building will be not stable and rehanged due to ideas
Therefore, this scenario will be developed continuously

Here is an interesting article on building height. Kinda lengthy but thought provoking.

Feel free to crosspost as it might be relevant to other threads as well.
