World's Tallest Building to Rise Higher than Mount Fuji

The X-Seed 4000 gives "highrise" a whole new meaning!The X-Seed 4000 gives "highrise" a whole new meaning!
At 13,123 feet high, the massive, mountain-shaped building envisioned by Japan's Taisei Construction Company would overshadow Mount Fuji itself by nearly 700 feet. That's the equivalent of NINE Empire State Buildings stood one upon the other!

A city within a cityA city within a city
The building, known as the X-Seed 4000, is designed to house up to one million residents on as many as 800 floors! Designers have had to consider tricky questions of temperature and pressure differentials between the base and topmost floors, and are looking to utilize solar power to solve these and other critical issues. The cost, you ask? Somewhere between $300 and $900 billion... what's that, an Iraq War or two? Couple of manned Mars missions? Quite do-able - if you're Japan, one of the world's richest countries.

Home to a million pharoahsHome to a million pharoahs
One might think the Japanese government would never allow the placing of an edifice the size of the X-Seed 4000 anywhere near sacred Mount Fuji, but Taisei's plans call for the monumental mini-city to rise relatively close by, rising up upon huge caissons sunk deep into the mire underlying Tokyo Bay.

Above the crowds and above the cloudsAbove the crowds and above the clouds
Could it happen? Well, skeptical citizens of Florence, Italy, scoffed at Leonardo da Vinci's detailed drawings of helicopters and other flying machines. Yet da Vinci's dreams did take flight, centuries later. I wouldn't rush to put down a deposit on a unit just yet, but Taisei's outrageous X-Seed 4000 proposal has the same potential to fly high.

Maybe the same will happen as with the Tower of Babel in acient times.

I don't think this will ever take off. A MILLION people in a building? Nah... They won't build it.

Why do we need building to house that many people? Humanity doesn't need to continue to grow, so many of our current world problems would be alleviated by reducing poppulation not continueing to expand it.

oh that's smart...can't wait

oh that's smart...can't wait for the earthquakes to test the tower's stability.

Good idea

That's a smart thing to build in a earthquake - tusnami prone area.

Looks like a setting for Logan's Run to me.  The earth was flat once - remember. Of course projects like this will happen.

Yeah, block out mount fuji.

Yeah, block out mount fuji. Good call.

It would definitely be a feat, but it would not be in my best interest to see horizons and mountains blocked.

Anyone check the demographics on this?

"Why do we need building to house that many people?... Humanity doesn't need to continue to grow..."

 Maybe you should ask humanity before flogging that viewpoint, hmm? But in fact, the Japanese birth rate has plummeted to the point that their population could drop by 20% by the middle of this century.

 And yet this mega-structure idea has been proposed. Maybe they figure that concentrating housing, services and jobs will prolong the useful working life of a collapsing population?

 In any event, do ask Uncle Google about the word "arcology."  This is an old idea whose time may be fast approaching.

Food for thought

In a crowded place like Tokyo the only way to go is up. Things like this are enevitable. Earthquakes are no longer an issue. Mexico City is home to a skyscraper that uses shock absorbers and a pendulum system to withstand earthquakes. The last earthquake Mexico City experienced the building held up with no damage even though surrounding buildings experienced minor structural damage and broken windows. The pyramid's sloping design will help it weather high winds as it breaks away from the vertical designs common to very tall buildings. Many sky scrapers with flat, perpendicular-to-the-base surfaces have to factor in the sway of the building as it tries to resist wind. The Science channel did a special on hypothetical architecture and something similar to this was on there. A lot of consideration and forethought went into this and I was impressed.

whats with the negativity u all westerner arent the most advance of human race...

if this project go on n complete, u westerners would eventually have to live there since your country is under the water lever flooded...cant see it now us is flooding, uk is also following in its foot steps oh and india too.

and about the fire....they would build some thing that big without thinking of the implication of fire hazard damn u people...they arent as stupid as you OK...

With all buildings of this

With all buildings of this type of concentrated human mass, the key thing to the buildings success is access, and you would need massive ,massive infrastructure to operate it, and some incredible redundancy, as the building would become a target of every type of trouble maker imaginable.

It would need a nuclear power station to supply the power, train stations and an airport to provide the massive transport hubs, and then there is the IT side. A building of this size would be controlled like something out of George Orwells 1984, as the security and Big Brother complex would run wild. I am not saying this is a bad idea, but there would be a definite "us and them" metatilty take over occupants and those"outside" Think of the movie Gattica, that is human nature at it's most primal, and it exists even today. Got to think about human nature here, no one, nomatter what the politcally correct brigade says, are ever polite all the time.

Ground Zero Is More Beautiful

A place where the grass is truly green

A place  crickets chirp at dusk

A place of cool streams with little fish and natural water

A place  I  dig the ground and plant  roses

A place little Bingo can play in the fields and poo without bother

A place called Ground Zero, where life is at its best

A place humans were designed to live . . .

You're not the brightest spark in the bunch

This idea is a dead one - an old one.

Also, by trying to say that every other country is ignorant or stupid you're just "Westener-bashing"... Whatever that is.

The idea of several billion people living in this brings a fair bit of skepticism to this from me, judging by the fact that it's rather small for several billion people to fit in - so I doubt that everybody in the world would go there to live.

Anyhow, if you're too thick to think your posts through then I don't think I should even bother to reply to the rest of your reply (How ironic). Doesn't it make you think that people like you are the least advanced of humanity? Yell

They are now making a smaller version of this

I was watching a show on inventions several months ago and they showed they were already making a smaller version of this.  They showed how they would deal with fire and earthquakes and any other disasters.  The smaller one gave them lots of opportunities to work out any design flaws and change anything they need to.  It is pretty awesome.  It's not done yet but it does have a lot of potential.

 I can't remember how big it was but it was pretty big and it's going to be livable too.  It'll be like a city all to itself.  No one would ever really need to leave.   There would be businesses and homes and schools all in one spot.  And on the ground I think there is a giant park for kids to play sports and have concerts and such.  Forget about parking!

Won't see it in my lifetime but it does have great potential.

Well that is a building that is really something. And it holds "only" a million people. There are already 6300 million people in world, so there could be many of those big buildings. But that building should not be an excuse to pollute and trash the rest of the world.
