Is it possible to build a mile-high skyscraper?
A mile-high tower would not just be a new structure, but a new technology.
- Frank Lloyd Wright originally proposed The Mile-High Illinois in the 1950s.
- Innovations in construction materials and elevators are necessary to reach the one mile height and beyond.
- We may see the first mile-high skyscraper by the middle of the 21st century.
Humanity has been on a quest for millenia to build bigger and taller structures. In our reach skyward we've built ziggurats, pyramids, and coliseums. Our mythologies placed the seat of the gods in lofty towers high on mountaintops. We've had moralizing religious parables like the Tower of Babel, warning those who'd place themselves above a god. And some of the self-proclaimed greatest among us have always sought to immortalize themselves through massive works.
It's safe to say our world civilization is one fixed on achieving ever higher milestones.
Yet, the dreams and wonders of yesterday's buildings look like children's toys compared to our structures now. In the past century and a half skyscrapers have come to dominate the city's form and they haven't stopped growing taller.
Now we have to ask ourselves, is it possible to build a skyscraper one mile high?
Perhaps. Let's find out.
Frank Lloyd Wright’s The Mile-High Illinois
One of the first legitimate plans to build a mile-high tower that wasn't some megalomaniac's fever dream (maybe his was too), was famed architect Frank Lloyd Wright's The Illinois.
On October 16th, 1956 at the Sherman House Hotel in Chicago, Wright at 89 years old presented his design for what he conceived to be the tallest skyscraper in the world, an incredible spire shooting one mile high. The structure proposed to stand 528 floors and 5,280 feet (1,609 meters) tall. Behind him stood an illustration that measured 25 feet (7.6 meters) tall with the skyscraper's dimensions drawn at a scale of 1/16 inch to the foot. The Illinois' dimensions would have been astronomical at the time, with:
- 528 floors
- 76 elevators
- Gross floor area (GFA): 18,460,106 ft² (1,715,000 m²)
- 100,000 occupants
- 15,000 parking spaces
- 100 helicopter landing pads
- Architectural height of 5,280 ft (1,609.4 m)
- Tip antenna height of 5,706 ft (1739.2 m)
"This is The Illinois, gentlemen… In it, will be consolidated all government offices now scattered around Chicago," Wright proclaimed.

Wright in an exemplary display of showmanship unveiled the first proposal for the mile-high tower. He believed that he'd found a method to construct the tower out of two principles he coined "tenuity" and "continuity." With these methods he'd believed he would be able to construct the tower out of reinforced concrete and steel.
The general principles between these two ideas is characterized by Wright's designs in which he used a "taproot" foundation to support the central load of the structure.
Chicago Tribune's Blaire Kamin described it as follows:
"The Mile-High didn't simply aim to be tall. It was the ultimate expression of Wright's "taproot" structural system, which sank a central concrete mast deep into the ground and cantilevered floors from the mast. In contrast to a typical skyscraper, in which same-size floors are piled atop one another like so many pancakes, the taproot system lets floors vary in size, opening a high-rise's interior and letting space flow between floors."
In Wright's own words he saw his method as a break from conventional form, which instead he'd mimic the appearance of a tree with its deep roots and branches spreading deep into the foundation.
"I detest seeing the boys fooling around and making their buildings look like boxes," Wright said. "Why not design a building that really is tall? ... Long ago I observed trees after the passing of a cyclone. Those with deep taproots were the ones that survived."
As evident by our lack of sky cracking buildings, Wright's vision never came to pass. His taproot idea, which had only been put into practice in a single building of his, never became part of the future structural engineer's toolkit. While Wright did put an extraordinary amount of effort working out the details of this vision, there were far too many what-ifs that still hadn't been figured out. Many of which we're still working on today.
But there has been progress.
Building technology for a 1-mile skyscraper
The undefeated champion of the skies right now is the Burj Khalifa in Dubai, which stands at 2,717 feet (roughly half a mile) and is the tallest building in the world.
Although take that with a grain of dusty salt—only 1,916 feet of the Burj Dubai is occupiable space, the rest is vanity height, meaning nearly 800 feet is non-occupiable space. That represents 29 percent of the building's height.
So let's get back to real contenders for a mile high.Researchers at MIT Technology Review used data from the experts at the Council on Tall Buildings and Urban Habitat and predicted that there is a 9 percent chance that a building exceeding a mile will be built by 2050. They've also predicted that by 2050, nearly 6 billion people will live in cities. Already we're seeing that urban areas in China and the Middle East are continually building up, not out.

There are three major construction and stability aspects that must be dealt with if we're to reach a vertical mile. Those are:
- Dampening wind sway
- Elevator speed and length
- Construction materials
The tallest skyscrapers all employ a tapered top design. This serves both a utilitarian and structural purpose. It's simply not possible to take pre-existing buildings and just double their height.
A mile-high tower would not just be a new structure, but a new technology.
Putting aside Burj Khalifa's vanity height for a moment, we have to admire its structural ingenuity. Designed by architect Adrian Smith and structural engineer William Baker at Skidmore, Owings and Merrill, the structure's foundational approach is a buttressed core – which is a hexagonal concrete core that frays out into three triangle buttresses. This was one inventive solution they made to support such a great height.
But that only solves one issue.
Diverting winds at high elevations
What might be a slight breeze on the ground floor can turn into a windstorm in greater heights. Aside from the fundamentals of stability, occupants also need comfortability. Most building sway is harmless to the structural integrity of the building. But the last thing anyone wants is to feel like they're in the midst of a tornado 500 floors above ground level.
Architecture, engineering, and construction (AEC) professionals calculate estimated wind sway from a building's height and incorporate that into the design. Buildings are often made to withstand cataclysmic 500 to 1000 year inclement weather disasters.
To deal with wind, you either confuse it by spinning it around the building in creative structural ways or you use a mass dampener.
A mass dampener is a counterweight suspended somewhere in the building to counteract and balance the movement from the outside. For example, the Taipei 101 Tower employs a 730 ton orb pendulum that sways back and forth to balance wind from storms and typhoons.
Aerodynamic vortexes of wind can exert dangerous amounts of pressure and vibrations on a building. Air currents can be unpredictable, so rather than guess what could happen to the building, AEC professionals need to calculate it directly into the design. If it's not a mass dampener, it'll be a mix of structural fins, curves, and asymmetrical floors.
Elevator speed and stability
The logistical obstacles of moving thousands of people in a mile-high skyscraper is one of the biggest challenges. To reach the floor at the top of a mile-high building with current technology would require people to change elevators multiple times.
The current figure for elevators runs at 1,600 feet as wire suspension ropes cannot support their own weight and any additional weight after that point. Aside from the technical limitations, needing multiple elevator lobbies would take up too much valuable space.
A few years ago, Finnish elevator company Kone developed a carbon fiber cable, UltraRope that they believe could double the distance of an elevator rope. This would be enough to get those would-be mile-high penthouse residents to their sky digs.
Beyond the old school cable elevator, others have floated ideas about a looped system that could pull elevators up, down and sideways. This could increase the building's usable area by 25 percent.
New structural materials
Concrete has served us well for thousands of years. It's time to rethink what materials we can use. Engineers are looking at materials like carbon fiber, an extremely lightweight and strong material.
Carbon fiber is a polymer composed of thin strands of carbon atoms bound together in a unique crystalline formation. It is far lighter than steel, five times stronger and has double the stiffness. Currently carbon fiber is used in a number of manufacturing processes ranging from aircraft wings to bike frames. Carbon fiber and other related composite materials weigh very little but can take on heavy bearing loads.
The future of the mile-high skyscraper
With billions of residents in our cities, it's an inevitability that we'll one day reach the one-mile-high mark, if not beyond that as well. But we need to think about what these skyscrapers will be used for and how they'll interact with and reshape the built environment.
At the turn of the 20th century, the 1916 Zoning Resolution in New York City was a measure adopted to stop massive skyscrapers from blocking light and air from reaching the streets below. It established limits to what could be built and created a series of setbacks to building lots.
New measures would need to be created as a building of this magnitude entered into the public domain. New building uses also need to be considered. How many more luxury condos and office space do we really need?
The advent of a mile-high tower could bring about a new age of the homestead and of our created environment. We have the opportunity to build something that could be a fully functioning self-contained ecosystem, more than just a building, but a city within a city.
A mixed use building like this could shelter thousands and give them a place where they could work, play, live, and exist on the peripheries of humankind's greatest ingenuity. A place like this could also serve as a consolidated seat for governments and working space for companies of the future. Why not continue to build vertically with farms, factories, and more?
When we one day build to a mile and beyond, the sky will no longer be the limit, it will be our domain.
Northwell Health is using insights from website traffic to forecast COVID-19 hospitalizations two weeks in the future.
- The machine-learning algorithm works by analyzing the online behavior of visitors to the Northwell Health website and comparing that data to future COVID-19 hospitalizations.
- The tool, which uses anonymized data, has so far predicted hospitalizations with an accuracy rate of 80 percent.
- Machine-learning tools are helping health-care professionals worldwide better constrain and treat COVID-19.

It's hard to stop looking back and forth between these faces and the busts they came from.
- A quarantine project gone wild produces the possibly realistic faces of ancient Roman rulers.
- A designer worked with a machine learning app to produce the images.
- It's impossible to know if they're accurate, but they sure look plausible.

The freemium online app intelligently generates new images from existing ones and can combine multiple images into…well, who knows. It's addictive — people have so far used it to generate nearly 72.7 million images, says the site — and it's easy to see how Voshart fell down the rabbit hole.</p><p>The Roman emperor project began with Voshart feeding Artbreeder images of 800 busts. Obviously, not all busts have weathered the centuries equally. Voshart told <a href="https://www.livescience.com/ai-roman-emperor-portraits.html" target="_blank" rel="noopener noreferrer">Live Science</a>, "There is a rule of thumb in computer programming called 'garbage in garbage out,' and it applies to Artbreeder. A well-lit, well-sculpted bust with little damage and standard face features is going to be quite easy to get a result." Fortunately, there were multiple busts for some of the emperors, and different angles of busts captured in different photographs.</p><p>For the renderings Artbreeder produced, each face required some 15-16 hours of additional input from Voshart, who was left to deduce/guess such details as hair and skin coloring, though in many cases, an individual's features suggested likely pigmentations. Voshart was also aided by written descriptions of some of the rulers.</p><p>There's no way to know for sure how frequently Voshart's guesses hit their marks.

New research suggests you can't fake your emotional state to improve your work life — you have to feel it.
What is deep acting?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTQ1NDk2OS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxNTY5MzA0Nn0._s7aP25Es1CInq51pbzGrUj3GtOIRWBHZxCBFnbyXY8/img.jpg?width=1245&coordinates=333%2C-1%2C333%2C-1&height=700" id="ddf09" class="rm-shortcode" data-rm-shortcode-id="9dc42c4d6a8e372ad7b72907b46ecd3f" data-rm-shortcode-name="rebelmouse-image" data-width="1245" data-height="700" />
Arlie Russell Hochschild (pictured) laid out the concept of emotional labor in her 1983 book, "The Managed Heart."
Credit: Wikimedia Commons<p>Deep and surface acting are the principal components of emotional labor, a buzz phrase you have likely seen flitting about the Twittersphere. Today, "<a href="https://www.bbc.co.uk/bbcthree/article/5ea9f140-f722-4214-bb57-8b84f9418a7e" target="_blank">emotional labor</a>" has been adopted by groups as diverse as family counselors, academic feminists, and corporate CEOs, and each has redefined it with a patented spin. But while the phrase has splintered into a smorgasbord of pop-psychological arguments, its initial usage was more specific.</p><p>First coined by sociologist Arlie Russell Hochschild in her 1983 book, "<a href="https://www.ucpress.edu/book/9780520272941/the-managed-heart" target="_blank">The Managed Heart</a>," emotional labor describes the work we do to regulate our emotions on the job. Hochschild's go-to example is the flight attendant, who is tasked with being "nicer than natural" to enhance the customer experience. While at work, flight attendants are expected to smile and be exceedingly helpful even if they are wrestling with personal issues, the passengers are rude, and that one kid just upchucked down the center aisle. Hochschild's counterpart to the flight attendant is the bill collector, who must instead be "nastier than natural."</p><p>Such personas may serve an organization's mission or commercial interests, but if they cause emotional dissonance, they can potentially lead to high emotional costs for the employee—bringing us back to deep and surface acting.</p><p>Deep acting is the process by which people modify their emotions to match their expected role. Deep actors still encounter the negative emotions, but they devise ways to <a href="http://www.selfinjury.bctr.cornell.edu/perch/resources/what-is-emotion-regulationsinfo-brief.pdf" target="_blank">regulate those emotions</a> and return to the desired state. Flight attendants may modify their internal state by talking through harsh emotions (say, with a coworker), focusing on life's benefits (next stop Paris!), physically expressing their desired emotion (smiling and deep breaths), or recontextualizing an inauspicious situation (not the kid's fault he got sick).</p><p>Conversely, surface acting occurs when employees display ersatz emotions to match those expected by their role. These actors are the waiters who smile despite being crushed by the stress of a dinner rush. They are the CEOs who wear a confident swagger despite feelings of inauthenticity. And they are the bouncers who must maintain a steely edge despite humming show tunes in their heart of hearts.</p><p>As we'll see in the research, surface acting can degrade our mental well-being. This deterioration can be especially true of people who must contend with negative emotions or situations inside while displaying an elated mood outside. Hochschild argues such emotional labor can lead to exhaustion and self-estrangement—that is, surface actors erect a bulwark against anger, fear, and stress, but that disconnect estranges them from the emotions that allow them to connect with others and live fulfilling lives.</p>
Don't fake it till you make it<p>Most studies on emotional labor have focused on customer service for the obvious reason that such jobs prescribe emotional states—service with a smile or, if you're in the bouncing business, a scowl. But <a href="https://eller.arizona.edu/people/allison-s-gabriel" target="_blank">Allison Gabriel</a>, associate professor of management and organizations at the University of Arizona's Eller College of Management, wanted to explore how employees used emotional labor strategies in their intra-office interactions and which strategies proved most beneficial.</p><p>"What we wanted to know is whether people choose to engage in emotion regulation when interacting with their co-workers, why they choose to regulate their emotions if there is no formal rule requiring them to do so, and what benefits, if any, they get out of this effort," Gabriel said in <a href="https://www.sciencedaily.com/releases/2020/01/200117162703.htm" target="_blank">a press release</a>.</p><p>Across three studies, she and her colleagues surveyed more than 2,500 full-time employees on their emotional regulation with coworkers. The survey asked participants to agree or disagree with statements such as "I try to experience the emotions that I show to my coworkers" or "I fake a good mood when interacting with my coworkers." Other statements gauged the outcomes of such strategies—for example, "I feel emotionally drained at work." Participants were drawn from industries as varied as education, engineering, and financial services.</p><p>The results, <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fapl0000473" target="_blank" rel="noopener noreferrer">published in the Journal of Applied Psychology</a>, revealed four different emotional strategies. "Deep actors" engaged in high levels of deep acting; "low actors" leaned more heavily on surface acting. Meanwhile, "non-actors" engaged in negligible amounts of emotional labor, while "regulators" switched between both. The survey also revealed two drivers for such strategies: prosocial and impression management motives. The former aimed to cultivate positive relationships, the latter to present a positive front.</p><p>The researchers found deep actors were driven by prosocial motives and enjoyed advantages from their strategy of choice. These actors reported lower levels of fatigue, fewer feelings of inauthenticity, improved coworker trust, and advanced progress toward career goals. </p><p>As Gabriel told <a href="https://www.psypost.org/2021/01/new-psychology-research-suggests-deep-acting-can-reduce-fatigue-and-improve-your-work-life-59081" target="_blank" rel="noopener noreferrer">PsyPost in an interview</a>: "So, it's a win-win-win in terms of feeling good, performing well, and having positive coworker interactions."</p><p>Non-actors did not report the emotional exhaustion of their low-actor peers, but they also didn't enjoy the social gains of the deep actors. Finally, the regulators showed that the flip-flopping between surface and deep acting drained emotional reserves and strained office relationships.</p><p>"I think the 'fake it until you make it' idea suggests a survival tactic at work," Gabriel noted. "Maybe plastering on a smile to simply get out of an interaction is easier in the short run, but long term, it will undermine efforts to improve your health and the relationships you have at work. </p><p>"It all boils down to, 'Let's be nice to each other.' Not only will people feel better, but people's performance and social relationships can also improve."</p>
You'll be glad ya' decided to smile<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="88a0a6a8d1c1abfcf7b1aca8e71247c6"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/QOSgpq9EGSw?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>But as with any research that relies on self-reported data, there are confounders here to untangle. Even during anonymous studies, participants may select socially acceptable answers over honest ones. They may further interpret their goal progress and coworker interactions more favorably than is accurate. And certain work conditions may not produce the same effects, such as toxic work environments or those that require employees to project negative emotions.</p><p>There also remains the question of the causal mechanism. If surface acting—or switching between surface and deep acting—is more mentally taxing than genuinely feeling an emotion, then what physiological process causes this fatigue? <a href="https://www.frontiersin.org/articles/10.3389/fnhum.2019.00151/full" target="_blank">One study published in the <em>Frontiers in Human Neuroscience</em></a><em> </em>measured hemoglobin density in participants' brains using an fNIRS while they expressed emotions facially. The researchers found no significant difference in energy consumed in the prefrontal cortex by those asked to deep act or surface act (though, this study too is limited by a lack of real-life task).<br></p><p>With that said, Gabriel's studies reinforce much of the current research on emotional labor. <a href="https://journals.sagepub.com/doi/abs/10.1177/2041386611417746" target="_blank">A 2011 meta-analysis</a> found that "discordant emotional labor states" (read: surface acting) were associated with harmful effects on well-being and performance. The analysis found no such consequences for deep acting. <a href="https://doi.apa.org/doiLanding?doi=10.1037%2Fa0022876" target="_blank" rel="noopener noreferrer">Another meta-analysis</a> found an association between surface acting and impaired well-being, job attitudes, and performance outcomes. Conversely, deep acting was associated with improved emotional performance.</p><p>So, although there's still much to learn on the emotional labor front, it seems Van Dyke's advice to a Leigh was half correct. We should put on a happy face, but it will <a href="https://bigthink.com/design-for-good/everything-you-should-know-about-happiness-in-one-infographic" target="_self">only help if we can feel it</a>.</p>
