An alternate History: If Martin Luther King had not been killed?

A life devoted to peace ended in a sickening act of violence on April 4, 1968. The gunshot that echoed across the parking lot of the Lorraine Motel in Memphis, Tennessee, not only took the life of 39-year-old Martin Luther King Jr., it silenced one of the world’s most strident voices against racism, war and poverty. It also left a lingering question: How would the course of history have been different had the social activist and civil rights leader not been felled by an assassin’s bullet nearly 50 years ago?

Had Martin Luther King Jr. not been killed as he stood on the Lorraine Motel’s second-floor balcony on that spring evening in 1968, it’s almost certain that the Baptist preacher would have remained a powerful voice against injustice. While King would have spoken out against racism in the ensuing years, it’s important to remember that the 1964 Nobel Peace Prize winner had begun to pivot his activism to economic inequality and antiwar causes by the time of his death, says Stanford historian Clayborne Carson, who also serves as director of the university’s Martin Luther King Jr. Research and Education Institute. It was economic inequality and fair housing that led him to march through a rainstorm of bottles and bricks in Chicago in 1966 and drew him to Memphis in support of striking sanitation workers.

“I don’t think of him primarily as a civil rights leader during the last years of his life,” Carson tells HISTORY. “Once the Voting Rights Act passed in 1965, his goals extended beyond civil rights at that point. In his Nobel Prize lecture he pointed out the triple evils in the world. Racial oppression was one, but poverty and war were the other two, and those were what he had turned his attention to.”

“The entrenched racism King confronted during his trip to Chicago in 1966 and the escalation of the Vietnam War broadened his understanding of civil rights to include the entire national landscape and the nation’s role abroad,” says Lillie Edwards, professor emerita of history and African-American studies at Drew University. “By 1968, this broader landscape signaled that he was fully engaged in keeping pace with new arenas of social justice and willing to embrace new paradigms and new strategies.”

High on King’s list of plans was the Poor People’s Campaign, which he had announced in November 1967 along with other civil rights leaders. He planned for an initial group of 2,000 impoverished Americans of all races to descend upon Washington, D.C., in May 1968 to lobby for an “economic bill of rights” that included jobs, unemployment insurance, a fair minimum wage and more low-income housing.

Before they could march into the nation’s capital, however, King’s followers found themselves marching behind a a mule-drawn wagon bearing his casket through the streets of Atlanta. The Poor People’s Campaign went on as scheduled, but it floundered without King’s leadership. The “economic bill of rights” never came to fruition.

Edwards says King’s presence would have boosted the profile of subsequent anti-poverty campaigns. “Supporting garbage workers in Memphis signals to us that King would have been a hands-on participant in movements to empower the poor and working class. His presence would have provided additional gravitas, leverage and media attention to local movements that the media and general population might have ignored,” she says.


Had King lived, he likely would have continued to speak out against U.S. involvement in the Vietnam War. Exactly one year before his death, King delivered one of the most controversial speeches of his life inside Manhattan’s Riverside Church in which he called the U.S. government “the greatest purveyor of violence in the world today” and said it was morally indefensible to send African-American troops to “guarantee liberties in Southeast Asia which they had not found in southwest Georgia and East Harlem.”

While some argue that racial relations would have been different had King lived, Carson says that expectations that King could have dramatically altered the ensuing direction of the civil rights movement, “economic bill of rights” and Vietnam War discount the power of the turning tide of the country. “The United States is like an ocean liner. One person is not going to change its momentum and direction. Even a great individual would not be able to turn it around and make it go in a different direction. The basic attitudes of people don’t change rapidly, and the nation was heading in a much more conservative direction after the 1964 election. We entered an era in which it was difficult enough to defend the gains that had been made before.”


In the year before King’s death, peace advocates tried to draft him to join a third-party antiwar ticket to run with pediatrician Benjamin Spock in the 1968 presidential election. King ultimately decided against a try for political office, and Carson doesn’t believe that he would ever have done so in the future, unlike civil rights leaders such as Andrew Young and Jesse Jackson who were at King’s side when he died. 

“He made a decision that he was not going to be a candidate for office,” Carson says. “He would continue to be a voice in the political arena but as a private citizen.”

Ironically, there may never have been a federal holiday honoring King had he not been killed so suddenly in 1968. King was not a universally revered figure at the time of his assassination. In the five years leading up to his death, King appeared on the top 10 of Gallup’s most-admired list only twice—in 1964 and 1965. In 1967 Alabama’s segregationist governor, George Wallace, ranked eighth on the list, while King could not crack the top 10. Gallup reported that nearly twice as many Americans in 1966 had a negative view of King as a positive one—and that was even prior to his controversial Riverside Church speech. By 1999, however, a Gallup poll found that King ranked behind only Mother Teresa as the century’s most-admired person.

Edward says public memory of King would have been quite different had he lived. “King is a martyr whose nobility of consciousness—non-violence—is embedded in the American and international consciousness,” she says.

 “However, King’s martyrdom has also diluted, if not erased, the power of his militant and revolutionary messages about human dignity and taking immediate rather than piecemeal action. Some people find it easy to embrace what I call ‘the birthday King’ who is devoid of urgency and militancy. The public has framed a ‘moderate’ King as a foil to a ‘militant’ Malcolm X for this reason.”


Death brought King a reverence that never existed during his life, and in 1983 the federal government designated his birthday as an annual holiday. “If he had lived, there clearly wouldn’t be a Martin Luther King holiday,” Carson says. “I think it was easier to see the idea of the holiday when he was no longer around.”

In Australia, bees and wasps are more dangerous than spiders and snakes

Australia has a reputation for being a hotbed of deadly spiders, snakes, and jellyfish, but a new study shows that bees and wasps are not to be trifled with either, because they're actually Australia's most dangerous stingers.

The country's first national analysis of data on bites and stings reveals that bees and wasps send the most people to hospital each year, and contribute to the equal highest number of sting-related deaths.

A team led by public health researcher Ronelle Welton from the University of Melbourne analysed national coronial data from 2000 to 2013, when bites and stings resulted in almost 42,000 hospitalisations, including fatalities.

Among this, stings from bees, wasps, and hornets were responsible for 31 percent of hospital admissions, edging out bites from Australia's more infamous venomous predators – spiders (30 percent) and snakes (15 percent).

But while snake bites requiring hospitalisation may be significantly less common than stings and bites from bees, wasps, and spiders, they're no less deadly when it comes to causing fatalities – and in fact are the most lethal proportionally.

Between 2000 and 2013, 64 people were killed by a venomous sting or bite, with 27 fatalities due to snakes, and an equal number attributable to bees and wasps.

Even more remarkable, despite popular fears of Australian spiders – which are pretty well-warranted, given they sent almost 12,000 people to hospital during 2000 to 2013 – they're not ultimately as deadly as we might think they are.


During the study period, spider bites didn't cause a single fatality, which the researchers attribute to the success and availability of anti-venom treatments.

According to the team, the last documented death from a spider in Australia was a redback spider bite in 1999.

A 2016 fatality was also reportedly due to a redback bite, but the cause of death wasn't conclusive.

In terms of non-venomous animals causing death, again the perception of Australia's dangers doesn't meet up with reality.

While the coronial data shows that 19 deaths between 2000 and 2013 were due to crocodiles, and 26 deaths caused by sharks, the leading animal-related cause of death was a much less fearsome creature: horses.

In the period, 74 deaths were caused by horses trampling or throwing people – and encounters with dogs led to 23 fatalities.

But in terms of venomous creatures, the fact that so many deaths and hospitalisations are being caused by bees and wasps suggests that people might not realise how dangerous these stingers really are.

Of the 27 snake bite fatalities recorded in the study, about three-quarters of those bitten made it to the hospital alive, before later dying during treatment.

When it comes to bees and wasps though, only 44 percent of those who died made it to hospital alive, and the researchers think it's because they initially underestimated the danger – not realising how deadly sting-based anaphylaxis (severe allergic reaction) can be.

"Perhaps it's because bees are so innocuous that most people don't really fear them in the same way they fear snakes," says Welton.

"Without having a previous history of allergy, you might get bitten and although nothing happens the first time, you've still developed an allergic sensitivity."

Allergen sensitivity in Australia made headlines around the world last year, when eight people were killed and more than 8,500 hospitalised after a severe outbreak of thunderstorm asthma, brought on by a massive pollen dispersal following a storm.

The researchers hope their findings will help better inform people and health providers about the real risks posed by Australia's stingers and biters.

And at the same time, if the research can provide a little context – and help lay to rest some of the hyperbole and stereotypes swirling around the country's 'deadliest creatures' – that might not be a bad thing either.

"The biggest surprise is just how small the numbers are — from a national perspective, we get a lot of media hype on how dangerous [animals] are, but if you look at things like drowning, there was nearly 5,000 deaths in the same study period," Welton told Loretta Florance at ABC News.


"[S]o it's nothing to be alarmed about, just be prepared, make sure you understand your first aid, if you do have allergies or know someone who does."

8 Mysterious Underground Cities

There’s not much to be said for the views, but underground cities have frequently been used throughout history as wartime shelters, refuges from the elements and sacred spaces. Many even included dedicated infrastructure and their own subterranean schools and churches. From ancient hideouts to Cold War-era bunkers, explore eight astonishing settlements beneath the earth’s surface.


Derinkuyu underground city

This labyrinthine complex dates to around the 8th century B.C. and was most likely built to serve as a refuge during periods of war and invasion. With this in mind, its 18-story interior was a self-contained metropolis that included ventilation shafts, wells, kitchens, schoolrooms, oil presses, a bathhouse, a winery and living space for some 20,000 people.

When threatened by attack, each level of the city could be sealed off behind a collection of monolithic stone doors. Historians believe that the Hittites or the Phrygians were among Derinkuyu’s earliest builders, but it was later occupied and expanded by a host of other groups including Byzantine-era Christians, who left behind a collection of underground frescoes and chapels. Despite its long history, the city wasn’t rediscovered until the 1960s, when a local man stumbled upon some its tunnels while renovating his home.


Naours


Located in northern France, the underground city of Naours includes two miles of tunnels and more than 300 man-made rooms—all of them hidden some 100 feet beneath a forested plateau. The site began its life around the third century A.D. as part of a Roman quarry, but it was later expanded into a subterranean village after locals began using it as a hiding place during the wars and invasions of the Middle Ages

At its peak, it had enough room for 3,000 inhabitants and included its own chapels, stables, wells and bakeries. The Naours caves were later sealed off for decades before being reopened in the 19th century as a tourist attraction

They became a popular sightseeing spot during World War I, and modern visitors can still see more than 2,000 pieces of graffiti left behind by Allied soldiers, many of whom fought nearby at the Battle of the Somme.


Wieliczka Salt Mine


Also known as the “Underground Salt Cathedral,” Poland’s Wieliczka Salt Mine is a massive subterranean complex of rooms, passageways and statues located on the outskirts of Krakow. The site dates to the 1200s, when miners first descended beneath the earth’s surface to find rock salt. In the centuries that followed, they slowly carved the mine into a warren of galleries and tunnels that extended more than 1,000 feet underground.

When they weren’t digging for “white gold,” the workers also used the mine’s salt crystal deposits to build a stunning collection of chapels, chandeliers, statues and bas reliefs, including a detailed replica of Da Vinci’s “The Last Supper.” The Wieliczka mine stopped producing salt in 2007 after some 700 years in operation, but it remains a popular tourist attraction in Poland. It’s also home to a health spa that touts the therapeutic properties of the mine’s salt-rich microclimate.

Lalibela


In the 12th century A.D., a devout king ordered the construction of 11 eye-catching Christian churches in the Ethiopian village of Lalibela. This “New Jerusalem” is notable for having been fashioned from the top down: all of its churches were hewn from volcanic rock below the earth’s surface then hollowed out, giving them the appearance of having grown directly out of the ground.

The most iconic building is the cross-shaped Church of Saint George, which was cut from a monolithic slice of stone inside a trench 100 feet deep. It was then connected to the rest of the complex via a network of underground passageways, hidden caves and catacombs. Legend has it that the construction of Lalibela took just 24 years, but many historians believe it was actually completed in phases over several centuries. The village is now considered a sacred site for the Ethiopian Orthodox Church, and its subterranean places of worship continue to draw as many as 100,000 pilgrims each year.


Beijing Underground City


In the 1960s and 70s, as the threat of nuclear war loomed, the Chinese government ordered the construction of a mammoth fallout shelter beneath their capital of Beijing. Also known as Dixia Cheng, the hand-dug site was supposedly capable of safeguarding around one million people for up to four months.

It consisted of fallout-proofed rooms and tunnels that snaked their way underground over an area of several dozen square miles. Certain passageways were reportedly large enough for tanks to pass through, while other housed purpose-built schools, hospitals, granaries and restaurants. There was even a skating rink and a 1,000-seat movie theater. While the Beijing bunker was never put to use, its decaying tunnels still exist today, hidden beneath the city’s homes and businesses. Most are sealed off, but they were briefly opened as a tourist attraction in the early 2000s.



Famed for its cameo in the film “Indiana Jones and the Last Crusade,” Petra is an ancient caravan city tucked away in the mountains of southern Jordan. The site has been inhabited since prehistory, but it reached its peak some 2,000 years ago, when the ancient Nabataeans hand-chiseled the surrounding sandstone hillsides into a dazzling collection of tombs, banquet halls and temples

One of the most exquisite edifices is Al Khazneh, or “The Treasury,” which includes an ornamental façade that extends 130 feet up a rock face. Petra may have been home to 20,000 people at its height, but it was later abandoned sometime around the seventh century A.D. and wasn’t known to Europeans until the 1800s. Excavations at the site are still ongoing today, and it’s believed that the vast majority of its ruins may still lurk underground.




The Italian hilltop town of Orvieto is known for its white wines and picturesque architecture, but its most mysterious wonders lie underground. Beginning with the ancient Etruscans, generations of locals burrowed their way deep into the volcanic rock bluff on which the city was originally built.

The subterranean maze was first carved to build wells and cisterns, but over the centuries it grew to include more than 1,200 interlocking tunnels, grottoes, and galleries. Some chambers include the remnants of Etruscan-era sanctuaries and medieval olive presses, while others show signs of having been used as storage places for wine or roosts for pigeons—a common local delicacy. Orvieto’s underground city was also frequently employed as a hiding place during times of strife. As recently as World War II, people were still using certain sections as bomb shelters.



In the event of a Cold War-era nuclear strike, the most important members of the British government would have retreated to a 35-acre underground complex located 100 feet beneath the village of Corsham.

This “Burlington Bunker,” as it was codenamed, was first built in the 1950s from a series of existing tunnels and stone quarries. It contained office spaces, cafeterias, a telephone exchange, medical facilities and sleeping quarters—all of it designed to keep the British Prime Minister and some 4,000 other key government personnel alive during an emergency. There was even an in-house BBC studio that the PM could use to address the public. While never put into active use, the Burlington facility remained partially operational until 2004, when it was finally decommissioned and declassified.

Viking raids in the east: The fight for the riches of Constantinople

No place on Earth was as coveted by the Vikings as Constantinople, but the Scandinavian warriors could never breach the formidable defenses of the world’s richest city in spite of repeated attacks. It was only after the Vikings became the personal bodyguards of the Byzantine emperor that they grabbed a piece of Constantinople’s wealth.

The epic voyages of the Vikings to the British Isles, Iceland, North America and points west tend to obscure the fact that the Scandinavian warriors also ventured far to the east across Europe and parts of Asia. While the Danes and Norwegians sailed west, Swedish fighters and traders traveled in the opposite direction, enticed initially by the high-quality silver coins minted by the Abbasid Caliphate that sprawled across the Middle East.


Painting of The Invitation of the Varangians: Rurik and his brothers arrive in Staraya Ladoga.
These Vikings who crossed the Baltic Sea and descended across Eastern Europe were branded “Rus”—possibly derived from “ruotsi,” a Finnish word for the Swedes meaning “a crew of oarsmen” and the term from which Russia receives its name. As the Rus migrated down the Dnieper and Volga Rivers, they established settlements along trade routes to the Black and Caspian Seas and conquered the native Slavic populations in present-day Russia, Belarus and Ukraine.

By the middle of the ninth century, Rus merchants turned up in Baghdad. The capital of the Abbasid Caliphate may have been the world’s largest city with a population of more than one million people, but it failed to capture the Viking imagination like Constantinople, the capital of the Byzantine Empire that was said to harbor even greater riches.


“Silk and gold are the big lures,” says John Haywood, who chronicles the exploits of the Scandinavian raiders on four continents in his new book, “Northmen: The Viking Saga AD 793-1241.” “The Rus would have heard stories about the riches of Constantinople. The big attraction in trade was silk, which was a massively prestigious product for which they traded slaves, furs, beeswax and honey with the Byzantines. Constantinople was also one of the few places that still had gold coins, which were in short supply compared to the Roman period.”

Constantinople’s location on the shores of the Bosporus strait, which divided Europe from Asia, allowed it to become a prosperous crossroads of trade, the largest city in Europe and the richest city in the world. Great treasures necessitated stout defenses. The most-heavily fortified city in the world, Constantinople was encircled by a moat and three parallel walls. In addition, an iron chain that could be stretched across the mouth of the city’s harbor protected it from a naval assault.


It is not known when the Rus first reached Constantinople, but it was before 839 when Rus representatives arrived at the Frankish court as part of a Byzantine diplomatic mission. In June 860, the Rus launched a surprise attack on Constantinople at a time when the city was left largely undefended as Byzantine Emperor Michael III was off with his army fighting the Abbasid Caliphate in Asia Minor while the Byzantine navy was engaged with Arab pirates on the Mediterranean Sea.

In what the Greek patriarch Photius called “a thunderbolt from heaven,” the Rus plundered the suburbs of Constantinople and launched coastal raids around the Sea of Marmara in which they burned houses, churches and monasteries and slaughtered the patriarch’s servants. However, they never attempted to breach the city walls before suddenly departing in August. The Byzantines credited divine intervention, but the Rus likely departed to ensure they could arrive back home before winter set in.


A medieval Russian source details a second attack on Constantinople in 907 when a fleet of 2,000 ships encountered the iron chain blockading the harbor entrance. The resourceful Vikings responded by going amphibious, hauling their ships ashore, affixing wheels and dragging them overland before placing them back in the water on the other side of the chain before being repelled by the Byzantines. No Byzantine accounts of a Viking attack in 907 exist, however, and Haywood notes that the story could have been concocted as a way to explain a subsequent trade agreement between the Rus and the Byzantines.

In 941 the Rus launched a disastrous attack on Constantinople. With the Byzantine army and navy once again gone from the city, a fleet of 1,000 ships descended upon Constantinople only to be done in by 15 old dromons fitted with Greek Fire projectors that set the Viking ships ablaze. Weighed down by their armor, the Rus who avoided the flames by jumping into the sea sank to a watery demise. Others caught fire as they swam. When Byzantine reinforcements finally arrived, the Rus sailed for home.


A half-century later, the Vikings would be recruited to defend Constantinople instead of attacking it. When Byzantine Emperor Basil II faced an internal uprising in 987, Vladimir the Great gave him 6,000 Viking mercenaries known as Varangians to differentiate the native Scandinavians from the Rus who by the middle of the 10th century had assimilated with the native Slavs and lost their distinct identity. Impressed by the ferocity with which the Vikings battled the rebels, the emperor established the elite Varangian Guard to protect Constantinople and serve as his personal bodyguards.

 With no local ties or family connections that could divide their loyalties and an inability to speak the local language, the Varangians proved far less corruptible than Basil’s Greek guards.

“They were immensely well rewarded,” Haywood says of the Varangians. “They were given silk for everyday wear. If you are Scandinavian at that time, you are doing well if you have silk trim on your clothes. They get an enhanced share of the booty. It’s this trickle of well-to-do homecoming mercenaries that spreads this image of Constantinople as the promised land of fabulous wealth.”


The Varangian Guard fought in every major Byzantine campaign—from Sicily to the Holy Land—until Constantinople was captured by Crusaders in 1204. Visitors to one of the most famous sites in the city now known as Istanbul can see that the Vikings left their mark on Constantinople—literally. At least two runic inscriptions carved into the marble walls of the Hagia Sophia may have been engraved by members of the Varangian Guard.

Mystery of Lilly E. Gray from Salt Lake City - "Victim of the Beast 666"

The legend, a synopsis: In the Salt Lake City Cemetery, there is a gravestone for a woman named Lilly E. Gray with an inscription that reads, "VICTIM OF THE BEAST 666." Many people have attempted to research this stone and Lilly, but strangely always hit a brick wall, as there is no information aside from her obituary, which states only that she died in a local hospital from natural causes.

Within the sublime Salt Lake City Cemetery, there is indeed a gravestone which has aroused interest and curiosity over the years, and has recently, with the advent of the internet, become the object of intrigue and fascination, amateur and oftentimes apathetic sleuthery. The stone is modest- a small, flat marker; the inscription is anything but: "VICTIM OF THE BEAST 666"

Cemetery legends abound. These stories, more often than not, especially when pertaining to specific gravestones and their inhabitants, tend to take on the attributes of the urban legend, mirroring societal fears, horror, and capitalizing on mystery; they usually have an associated thread of religious intrigue, including 'devil worship'. The legends also tend to arise from the most benign origins.

Part of the fascination with the Lilly E. Gray mystery could be due to its "legend in reverse" quality. The impetus is its blatant-ness, its in-your-face refence to satan, then an unravelling reveals "nothing". The strange lack of any story associated with Lily Gray's gravestone is its biggest mystery and also the not very festive centerpiece its own developing, unique legend. The stone's astonishing, provocative inscription begs for interpretation and meaning; where are all the suppositions? They are few, certainly. There are a couple websites that allude to the use of stone's image within a report by investigators of satanic ritual abuse hysteria. There are a few jokes in a thread about Lilly's husband perhaps being the 'beast.'

Salt Lake City is home of the massive LDS-operated Family History Library, and the world's geneaological research mecca--since the stone's erection in 1958 no one has dug deeply enough to uncover even a minimal account of Lily Gray's life and the origins of the inscription? When confronted with apparent true lunacy, evil, religious ferver, abuse, or implausible as it may be, ultimate victimhood at the hands of satan (as the stone literally implies) do we collectively turn our heads?

He was born into the family of a carpenter and had no money to study. It later became one of the great inventors of the world.

Portrait of James Watt (1736–1819) by Carl Frederik von Breda photo: wikipedia

On 19 January 1736 was born James Watt, inventor of the steam engine (d. August 25, 1819).

James Watt was born in the Scottish town of Greenock, Scotland, UK, in the family of a carpenter. In school he was interested in mathematical physics, other objects not having too brilliant results. He wanted to study at university but the family could not allow it. After much hesitation, it decided to learn precision mechanics items that in view of the precarious state of his health, it would not be exhausted.

He began studying at Glasgow, optics and mechanics in 1754. After just one year of teaching has gone to a manufacturer of mathematical tools, Morgan in London where he learned a lot and was highlighted by the precision and skill. which satisfied all her tasks incumbent.

In 1757, he obtained a place at the University of Glasgow as a mechanic. He found here a well stocked cabinet of physical conditions for further study and conduct experiments. The idea of steam engine began to preoccupy Watt after the first two years at university, at first without results.

When he was entrusted to repair the Newcomen's steam car model in 1765, it not only repaired, but it has also strived to improve his. He noticed that the steam from the boiler machine arrived only a few strokes of the piston, after the car had to wait until the boiler as steam again. It has focused on this issue for several weeks and found its solution: the steam not be formed directly in the cylinder, but separately, in another vessel bound for steam cylinder. Watt invented the condenser, heating cylinder valves at both ends, double-acting steam engine.

Due to financial problems, Watt is associated with Dr. Roebuck in 1769. It has been given a patent for the "new way of reducing steam consumption in cars, but the device built after the patent has not worked. The fault was not only imperfect seals the connections between different parts of the machine, but also the quality of material used. Watt was separated from his partner, who gave up his part of the bargain to Boulton manufacturer.

Watt found support for his experiences and inventions, soon becoming his partner in the new car factory  "Boulton and Watt". Watt worked tirelessly to perfect the invention, which had caused so many disappointments.




In 1775 he managed to build the most important part - steam cylinder  that really work so the factory managed to produce the first steam car and, after a year, two. The machines were a success and the factory is ready for production.

For his merits, towards the end of life he received many honors. The most important are the fact that he was elected to the French Academy of Sciences, the Royal Society of London, doctor honoris causa of the University of Glasgow and others.

Watt was married twice. First wife had five children, and the second two, who died at an early age. Shortly before his death on August 19 1819 and it has been awarded the title of nobility. Watt refused and remained faithful to its modest origins and creative work he loved above all.

The greatest accomplishment is considered to be the patent in 1784 of the steam locomotive.

Watt is the one who introduced measurement unit called horsepower, to compare different powers steam machines of the time and which was then equivalent to lifting 550 pounds in one second, or the equivalent of 745.7 watt unit the power measurement in the International system.

The future is now: Engineers have released plans for a 5-km-high skyscraper that absorb smog

Credit: Arconic

2017 only just arrived, but one manufacturing company is already looking 45 years into the future.

Arconic, a materials science company, has envisioned a 3-mile-high (4.8-km) skyscraper built from materials that are either in-development or have already been brought to market, including smog-eating surfaces and retractable balconies.

The tower was concocted as part of the company’s larger campaign known as The Jetsons, an homage to the 1962 cartoon set in 2062. Arconic’s engineers worked alongside futurists to imagine the technologies that will be most useful several decades from now.

Sherri McCleary, one of Arconic’s chief materials scientists, says one of the most exciting and immediate projects is EcoClean, a special coating that helps buildings self-clean and purify the surrounding air.

It was first released in 2011 and offers a number of benefits over traditional pane glass windows, McCleary says.

"The functional coating provides aesthetics, it provides maintenance benefits, and it also provides a benefit to the surrounding environment by reducing the content of pollutants around it," she tells Business Insider.

EcoClean works with help from light and water vapour, which mix with the chemicals in the coating to produce atoms known as free radicals.

These free radicals pull in pollutants from the air and break them down to get sloughed off the side of the building along with dirt and grime - almost like dead skin.

The end result is a cleaner building surrounded by cleaner air.

Another innovation is in the windows themselves. The new design is called Bloomframe. Essentially, it’s a motorised window that converts into an all-glass balcony in under a minute.

Arconic has been showcasing the technology at trade shows around the world and will hit the market in the "near future", a company spokesperson says.

Rather than spend twice the money on materials to build separate windows and ledges, Arconic wants to invest in flexible components that can make buildings more than just static giants.

Skyscrapers built from 3D-printed materials could stretch more than 3 miles in the sky, Arconic says.

Some of Arconic’s other futuristic designs include flying cars, ultra-lightweight car bodies, and aerodynamic aeroplane wings.

In the meantime, it continues working to push the limits of what modern-day skyscrapers can look like and do. Thanks to 3D printing, McCleary says many structures that aren’t currently feasible could withstand high winds and unique climates.

"We’re looking at optimising the materials that can be 3D-printed to give more and more options to designers and architects," she says.
