The Bay Bridge Gets Its Glow On
![]()

Last week, for the first time in 75 years, the Bay Bridge, connecting San Francisco and Oakland, made the Golden Gate seem like just another bridge.
Kudos to Leo Villareal. He’s an artist who works with lights, but also with algorithms. And his latest project, The Bay Lights, is probably the most spectacular example of that mix of art and tech that most of us have ever seen.
Under Villareal’s direction, teams of electricians spent the past five months stringing 25,000 LED lights a foot apart–from the top of the bridge’s towers down to the deck–for the full length (almost two miles) of the bridge’s western span.
Drivers crossing the bridge aren’t distracted by the spectacle of all the white dots. They can’t see them. But from the shore, it’s a very different view. Sometimes the light seems to drip down like a steady San Francisco rain. Other times it looks like shadows of clouds moving over the bay. That’s the point. Villareal wants the lights to mirror the natural elements around them. And like nature, the bridge’s lights will never look exactly the same for the next two years. That’s the algorithms at work.
There are no cheap tricks–no splashes of color, no words spelled out, no images–in fact, nothing clearly identifiable. Just constantly shifting abstractions so people can see what they want to see.
Says Villareal: “My goal is to make it feel alive as possible, as alive as a sequence of numbers can be.”
Whither reality?
Public art has come a long way from statues of white guys on horses. And it’s not just about the scale of something like The Bay Lights. It’s what technology has made possible–art that’s dynamic, that shifts mood and shape and sometimes augments reality. Some, of course, are not impressed, seeing art by algorithm as not much more than a 21st century version of parlor tricks. So be it.
But there can be little question that digital technology is now the driver in not just how we interact with our environment, but also in how we view it. And whether its method is to enhance the world around us or to change entirely how it appears, this is where public art is headed.
Like Leo Villareal, B.C. Biermann is a digital artist who wants to provide fresh visions to city life. But he does it by offering slices of an alternative reality. His art projects involve adding a new interactive layer to public spaces.
A few years ago, he co-founded an organization called RePublic and one of its first augmented reality projects, in July 2011, allowed people to point their smartphones at specific Times Square billboards and instead of viewing massive, flashing ads, they were able to see original pieces of urban art. Next came a project in which people aiming a digital device at a fading mural in Norway could see what it looked like when its paint was fresh. And then came the augmentation of buildings in Los Angeles and New York, which were were transformed into fanciful virtual murals on the small screen.
Biermann is now looking at refining his augmented reality concepts so that people could have choices of what “surface” of a building they want to see. Maybe they get an image of what it looks like inside the walls, maybe how it might look 20 years from now. He’s also working with an architecture professor at Washington University in St. Louis to develop a version of his app that would digitally revitalize several of the city’s buildings, with the goal of showing how better urban planning can profoundly change a streetscape’s looks.
As Biermann sees it, one day we may be taking virtual tours of cities, but what we see on our smartphones could be a very different-looking place than the one before our eyes.
That is, if we’re still paying attention to the one before our eyes.
Art palpitations
Here are a few other public art projects built around digital technology:
- But the lights will not spell out, “Hi, Mom: Now that Bay Lights is in play, a little of the glitter is gone from Luminous, the light spectacle covering the front of a four-story building in Sydney, Australia. When it was unveiled last year, it was described as the world’s largest permanent interactive light display. And one big difference between it and the light show on the Bay Bridge is that it comes with touchscreens that give people in the restaurant down below the chance to become LED programmers.
- However, they refuse to dance to “Gangnam Style”: And in Winnipeg, Canada, they now have their own interactive art piece that makes up in whimsy what it lacks in grandeur. It’s a collection of 68 LED lights that react to sound, specifically whistling. Called Listening Lights, its inspiration is a Canadian legend that when a person whistles, the Northern Lights become more intense and dance towards the person doing the whistling.
- Finding their inner building: While it lasts for only a few days in January, the Ghent Light Festival in Belgium is worth a mention if you’re talking about doing digital magic on buildings. Here’s a video from the dazzling 2012 version of the event.
- And they should know at least a few insults: And here’s one that’s a work in progress. Believe it or not, New York City still has 11,000 payphones, which actually came in pretty handy during Superstorm Sandy. But clearly they need a 21st century facelift and now the city has just announced six finalists in a competition to reinvent the payphone. The entries will be judged on what their reinventions can do. Are they wifi hotspots? A gatherer of data, such as street level pollution levels? Or a true urban kiosk, one that can wirelessly call a cab and be able to tell you what food trucks are where that day? And they have to look good. This is New York, after all.
Video bonus: See for yourself the spectacle of the new Bay Bridge and get an explanation of how it works from the artist himself in this New York Times video report.

Learning From Nature How to Deal With Nature
![]()

During his inaugural speech Monday, President Barack Obama uttered a phrase that during last year’s presidential campaign were The-Words-That-Shall-Not-Be-Spoken.
He mentioned climate change.
In fact, President Obama didn’t just mention it, he declared that a failure to deal with climate change “would betray our children and future generations.”
But ask any Washington pundit if Congress will do anything meaningful on the subject and they’ll tell you that that’s as likely as D.C. freezing over in July.
Also this week, as it turns out, a study was released outlining the latest geoengineering idea for saving the planet in the event of an unstoppable downward spiral of the Earth’s climate.
This one would involve dumping billions of tons of dust of the mineral olivine into the oceans, a process that, in theory at least, could significantly reduce carbon dioxide levels and also slow the increasing acidification of the oceans.
But there’s a catch. Actually, there are many. For starters, the German scientists who did the study estimate that it would require an undertaking as large as the entire world’s coal industry to mine enough olivine, and then it would take at least 100 large ships working 24/7 for a year to spread enough of the mineral dust around to have an impact. Plus, all that olivine dust would undoubtedly change the biology of the oceans in ways no one can really predict.
Back to nature
Okay, back to reality. The only response to climate change that’s truly moving forward is what’s known as adaptation. Or, put more simply, preparing for the worst.
It’s not likely that there will be another Hurricane Sandy this year. Maybe not next year either. But no one running a city, particularly along a coastline, can dare to think that the next devastating superstorm won’t come along for another 50 years.
So their focus is on minimizing the damage when it does hit. And, perhaps not surprisingly, they’re increasingly looking to nature’s resiliency to help them deal with nature’s wrath.
Case in point: One proposal to reduce future flooding of Lower Manhattan is built around the idea of converting part of that section of the city into wetlands and salt marshes. That’s right, the concrete jungle, or at least the lower end of it, would get very squishy.
As architect Stephen Cassell envisions the transformation, the edge of low-lying neighborhoods, such as Battery Park, would become a patchwork of parks and marshes that could sop up future storm surges. And on the more vulnerable streets, asphalt would be replaced with porous concrete that could soak up excess water like a bed of sponges.
It’s just one of several ideas that have been floated, but its mimicking of natural wetlands has a simple, rugged appeal. As Cassell told the New York Times:
““We weren’t fully going back to nature with our plan. We thought of it more as engineered ecology. But if you look at the history of Manhattan, we have pushed nature off the island and replaced it with man-made infrastructure. What we can do is start to reintegrate things and make the city more durable.”
Know your roots
But that’s almost prosaic compared to Skygrove, the concept for a skyscraper inspired by the mangrove tree. Mangroves, which often grow in swamps or along rivers, are known for their gnarly network of roots that keep their trunks above the water.
Architects at the New York firm of HWKN copied that model for a building that could sit above rising water. Instead of having a single foundation, the Skygrove would rest on a base of “roots” extending outward like fingers spread under the water.
Each root of the building–which is meant to be a vertical office park for the City of New York–would be independent of the others and self-sufficient, able to provide its own energy. And each would be designed to survive whatever extreme weather may come its way.
To believe the designers, the Skygrove is a model for the kinds of buildings we may see more often in what they call the “newly nebulous coastal zone.”
It’s nature’s way
Here are other new inventions based on mimicking nature:
- But do not try this on trees: A London industrial designer has created a super-strong bicycle helmet by modeling it after the heads of woodpeckers.
- No word yet on how it may affect human mating: A team of researchers has found that LED lights that copy the structure of a firefly’s “lantern” are 55 percent brighter.
- Okay, let’s clear the air: A Copenhagen chemist has invented an air-cleaning device that mimics the process through which the Earth’s atmosphere cleans itself. In response to sunlight, polluting gases rising into the sky form particles when they come across compounds such as ozone. And those newly formed particles are washed out of the atmosphere by rain. The invention, which removes industrial pollutants from the air, is now being tested at a Danish plant.
- But do they ever tell dogs “You’ll just feel a little stick?”: One day we could have less painful hypodermic needles thanks to a group of scientists who studied porcupine quills. They determined that the backwards-facing barbs on a quill help it enter skin easily and then stay in place. The researchers learned this by measuring how much force it took to push in and pull out porcupine quills jabbed into pig skin and raw chicken meat.
- Mussels and bodybuilding: A team of researchers from Penn State and the University of Texas, Arlington believe that a version of the powerful adhesive that allows mussels to stick stubbornly to underwater surfaces can be used in operating rooms to close and heal wounds.
Video bonus: An idea whose time, sadly, has come: robot cockroaches. It will creep you out.

10 Ways Travel Is Getting Better
![]()
Most Americans have already kicked into Thanksgiving mode, looking ahead to Thursday when they’ll sit down with family and friends, pile an unfathomable amount of food on their plates and then sleep it off to the soothing sound of supersized men smacking helmets on TV.
But between now and then madness lies. There will be traffic jams and long security lines and countless other aggravations that will make you wish that this year you had stayed home and opened a can of tuna.
Don’t despair. Believe it or not, traveling is getting easier. Here are 10 innovations that can help you now or give you hope about the future.
1) You’re the one who likes his cranapple juice shaken, not stirred: British Airways is breaking ground in showing passengers how much it knows about them. As part of its “Know Me” program launched last summer, the airlines is using data it has accumulated about its customers to allow flight crews to give them particularly personal service.
For instance, say a person is flying business class for the first time. That would be flagged 0n the crew’s iPads and a flight attendant could offer a special welcome and make sure he or she knew how to use the seat. Or someone who usually flies business class might instead be in coach taking a vacation trip with his family. A crew member might offer a free drink and make a fuss in front of the whole gang. That’ll score some points.
The big question, though, is when does knowing so much a customer slide from solicitous to creepy?
2) People you meet at airports can be so shallow: When they started showing up at a dozen or so airports around the world this summer, greeter avatars were by no means a sure hit. There was some concern that arriving passengers would be creeped out by holograms that go into a 90-second rap on airport info–location of baggage claim, bathrooms, etc.–as soon as anyone comes within 30 feet of them.
But generally the response has been positive, with plenty of passengers reaching for their cell phones to snap shots of these virtual women for the folks back home. And why not? They’re happy to be on a first-name basis. (Hi, I’m Eva…or Paige or Emily or Heather or Carla.) And they no doubt they bring back memories of Princess Leia, only they’re taller, have much better hair and are way too cheery to bring up anything having to do with Death Stars.
3) Because the real adventure starts after you leave the airport: Last year the Australian start-up Rome2rio launched its search engine designed to provide you with all the travel details for any trip–not just airport-to-airport, but door-to-door. So it includes train schedules and prices, driving routes, even ferry times, if that’s part of the journey. And just last month, it came out with an iPhone app that digs up the same info for you.
4) But can it make the cheapest be the fastest?: Madrid-based Amadeus has been in the airfare search business for several years now, but next year it hopes to take a big leap forward in simplifying the process for travelers.
Using a technology it calls Featured Results, it will be able to do a high-speed search of all possible fares between two locations and, in a matter of seconds, provide the top option in three different categories–the cheapest, the fastest, and the most popular.
5) The next best thing to not having a layover: Another tech product that’s been around for a few years is the mobile app GateGuru. It gives travelers the lowdown on the mysterious world beyond the gate–where you can find the best food, the best airport bar, the fastest security lines, a place to get a massage, the ATMs.
Now it’s entered into a partnership with JCDecaux, a company that handles advertising at airports. Which means the GateGuru content will soon be showing up in digital displays in airports. The first will be at Baltimore-Washington Airport.
6) And then you shoot on down to LA: You have to admit that Elon Musk has earned some cred when it comes to transportation. He’s co-founder of Tesla Motors–its Model S was just chosen Motor Trends’ “Car of the Year”–and founder of SpaceX–which last month flew the first commercial resupply mission to the International Space Station.
So when he talks about a transit system that he says could move people from San Francisco to Los Angeles in a half hour, you can’t dismiss him as someone who’s been munching on a bowl of crazy. Musk’s idea is something he calls “Hyperloop,” which he described as a cross between the Concorde and a railgun. Based on the few details he’s provided, it would be some kind of tube vehicle that would be able to leave as soon as you arrive and then get you to SF or LA in half the time a plane would take.
7) While you’re in the neighborhood: Airbnb started out as an online service that hooked up people looking for a place to sleep in another city or country with people willing to have strangers stay over. And it’s grown quickly–it has listings of 250,000 properties in 30,000 different cities around the world.
Now it’s taken a leap toward becoming more of a full-blown travel service by launching guides to the lesser-known neighborhoods where Airbnb clients are more likely to be staying. So far neighborhood guides have been rolled out in New York, Paris, London, San Francisco, Washington D.C., Berlin, and Rio de Janeiro.
8) What did you expect in Vegas, a milk store?: Given the location, this seems long overdue, but now an operation called the Liquor Library is open for business in Las Vegas’ McCarran Airport. It’s just as it sounds, a place where travelers can pick up beer, wine or booze–and not in some duty-free shop, but in a real live liquor convenience store that calls itself a library.
9) Surprise! There’s a Cracker Barrel in your future: Yes, we’d all like to be able to predict the future, but sometimes we’d settle for being able to know what’s off the next exit. That’s where mobile apps, such as Road Ninja, can make your life easier. It not only lets you know what’s up ahead, but you can also call ahead or read a restaurant review, although there’s only so much you can say about Denny’s Grand Slam.
10) What, no free cocktails for the parents?: Early next year, Air Asia will start setting aside a kid-free zone on its flights. And now a California consulting firm, RKS Design, has gone even further by dreaming up how an all-family airline might work.
They’ve named it cAir and it would feature express check-in services, stroller rentals and play lounges to keep the kids amused. The seats would be arranged so parents would face their kids, bathrooms would be large enough for diaper changes, and sound curtains could be pulled around a noisy little tyke. A kid would even be able to pick out a toy to play with during the flight–which parents would have the opportunity to buy if they can’t wrench it from his hands.
For now, it’s only a concept–no one’s sure if you could actually make a business out of the idea.
Video bonus: The Hobbit opens soon and fittingly Air New Zealand has started airing safety videos featuring a few flight attendants who look like they took a detour from Middle Earth. Sit back and relax, my precious.

Should Cities Prepare For the Worst?
![]()
Talk about being prescient.
Not quite two months ago Mireya Navarro wrote the following in the New York Times:
“With a 520-mile-long coast lined largely by teeming roads and fragile infrastructure, New York City is gingerly facing up to the intertwined threats posed by rising seas and ever-more-severe storm flooding.”
She also noted that critics say “New York is moving too slowly to address the potential for flooding that could paralyze transportation, cripple the low-lying financial district and temporarily drive hundreds of thousands of people from their homes.”
Actually, Navarro was not quite as oracular as it might seem. Scientists at Stony Brook University, working together as the ominously-named Storm Surge Research Group, have been beating this drum for years, warning that New York City becomes more vulnerable with each passing year as ocean levels rise. And last year, a New York State report estimated that a bad coastal storm could flood the subways and cost up to $58 billion in economic damage and revenue lost.
Even the city’s Museum of Modern Art has raised the spectre of a shrinking New York, with a 2010 exhibit titled “Rising Currents.” It included one architect’s vision of a Lower Manhattan defined by “a network of walkways that allow people to walk among the marsh and tall grass.”
Don’t speak of this
The idea of building a series of sea gates along Manhattan that could be closed during a major storm has been much discussed, but so far hasn’t moved much past the talking stage. For starters, there’s the potential cost, estimated at $10 billion, probably more. Also, it hasn’t helped that climate change has become the Lord Voldemort of political issues–you know, the He-Who-Must-Not-Be-Named guy.
Which helps explain why New York is hardly alone among American cities when it comes to being skittish about investing heavily in climate change protection, which, by the way, is now referred to as “resiliency planning.” In fact, according to a recent study at MIT, only 59 percent of U.S. cities are engaged in such planning, as opposed to 86 percent of cities in Australia and New Zealand, 84 percent in Europe and 80 percent in Africa.
Luckily, most American cities aren’t as close to the brink as New York when it comes to the impact of extreme weather. So they’ve been able to get by with adaptation more incremental than transformative.
But at least some cities are starting to make resiliency planning a core part of their 21st century agenda. Chicago, for instance, has for several years now, been repaving its almost 2,000 miles of alleys with permeable concrete, a surface that allows storm water to seep through into the soil below instead of streaming into an overwhelmed sewer system or flowing as polluted runoff into streams and rivers. And that water in the ground beneath the concrete also keeps the aIleys cooler during the blisteringly hot summers Chicago has suffered though in recent years. Soon the city will start using the porous pavement in bike lanes.
Chicago’s also become a leader in the development of green roofs--rooftops covered with grass, flowers and decorative bushes that not only cut a building’s air conditioning costs, but also reduce the amount of rainwater that pours down gutters and into the sewers.
Other cities, such as Philadelphia, Nashville and Houston, have become much more aggressive about planting trees in environmentally sensitive areas to help them counter the impact of storms capable of unloading several inches of rain in a day.
Why quibble?
Will that be enough? Maybe not. But one of the lessons from Sandy is that cities, in particular, no longer have the luxury of waiting for scientific certainty in linking extreme weather to climate change.
As Michael Oppenheimer, a professor of geosciences and international affairs at Princeton, told the Huffington Post:
“Whether or not there was a climate change component to this storm, it teaches us a lot of things, including how behind the 8-ball we are in being able to handle big events of the type that we believe — that scientists think — are going to get more frequent and intense in the future. So whether this one was 5 percent due to climate change or 1 percent or 10 percent — it’s interesting, it matters to a certain extent, but it’s not the whole story by any means.”
Jennifer Morgan, the director of the climate and energy program with the World Resources Institute, put it another way: “While it’s important to understand the scientific evidence underpinning these events, waiting for certainty that a particular storm or other event is caused by climate change is courting disaster. You don’t wait for 100 percent certainty that your house will burn down before you take out fire insurance.”

Can We Link Hurricane Sandy to Climate Change?

Getting Smart About Traffic
![]()
Usually I walk to work, but earlier this week, after another apocalyptic forecast of torrential rains and head-twisting winds, I fell prey to weather dread and drove in.
In no time, I was reminded of why Washington D.C. has the worst drivers in the U.S.–Allstate verified it–and also why it’s among the Top 10 congested cities in the country. The latest estimate is that drivers here waste an average of 45 hours a year in traffic jams. I don’t know if anyone’s come up with a comparable analysis of how much time the stress of sitting in gridlock takes off your life, but I’m guessing I said goodbye to 15 minutes or so that morning.
The experience revived my interest in the science of traffic flow and how GPS, sensors, and algorithms have made it possible to imagine a day when the commuting madness will end.
Here are some of the ways we just may get there:
1) Follow the wisdom of E. coli: That’s the thinking of two Chinese engineers wrestling with the hideous traffic of Guangzhou, a city of 13 million in southern China. They are advocates of applying “swarm intelligence” to traffic lights in the city, or more specifically, something known as Bacterial Foraging Optimization. This is an algorithm based on the behavior of E. coli, which, while very basic, ultimately results in the optimal solution to problems. In this case, the algorithm would be applied to stop lights, adapting them to traffic flow instead of keeping them on a fixed loop.
2) Failing that, you can still learn a few things from humans: Scientists at the University of Southampton in the U.K. found that real humans are better traffic controllers than computerized systems. So now they’re focusing on developing artificial intelligence for traffic control systems so they can learn from experience as humans do.
3) Or feel the pulse of social chatter: IBM studied traffic jams in three Indian cities over the past year through the social network comments of people stuck in them. The company’s evaluation of tweets, Facebook updates and other social network discussions of people in Mumbai, Bangalore and New Delhi is designed to show how social data can be used to read public attitudes on big urban issues, such as traffic. Among its findings: Drivers in New Delhi talked more about public transportation, weather and the stress of commuting, while those in Bangalore vented about the overall driving experience, construction and parking. And in Mumbai, they tended to rant about accidents and pollution.
4) Twitter intelligence is not an oxymoron: And Twitter is also being used in real time to stay on top of traffic accidents and backups on British highways. A mobile app called Twitraffic analyzes what people are saying on Twitter about traffic and warns you about problems that have popped up. The company behind the app claims it lets people know about accidents an average of seven minutes before the government’s Highways Agency does. It hopes to launch a U.S. version next month.
5) Meanwhile, back in the U.S.: There’s already a pretty impressive mobile app available here for helping you avoid commuting nightmares. It’s called Waze and it not only gives you directions, but it also monitors what other drivers are saying about what’s happening on the streets around you. It’s a traffic report through crowdsourcing, and one that constantly updates with new directions if there’s bad news coming in about the road ahead.
6) Just let the cars work it out: Since last month, about 3,000 vehicles around Ann Arbor, Michigan have been able to talk to one another. As part of a joint project of the U.S.Department of Transportation and the University of Michigan, the cars and trucks have been adapted to be able to communicate wirelessly and warn each other of potential accidents or backups. For instance, one vehicle could tell another when it’s approaching an intersection or if it’s stopping on the road ahead. The Michigan researchers think these wireless systems, if they become a standard feature, could cut accidents by 80 percent.
7) Car Talk was taken: MIT scientists are heading down the same road, developing something they calls CarSpeak. It’s a communication system for driverless cars that lets them “see” through the data provided by other cars on the road. And that would allow a car to cruise right through an intersection because it would know no other cars were coming.
Down the road
Here are a few other developments designed to help us get around:
- Not so mellow yellow: A researcher at Virginia Tech concludes that one of our big problems is yellow lights because they create what he calls a “dilemma zone” for drivers. He’s developing a system for giving drivers a few seconds notice when a light is about to turn yellow.
- We don’t need no stinking stretch limo: The largest buses in the world, 98-foot-long vehicles capable of carrying more than 250 people, will be rolled out in Dresden, Germany next month.
- Nothing makes an old man feel young like driving at night: According to a study at MIT, the most important car feature for drivers over 50 are smart headlights, which adjust the range and intensity of light based on the location of other cars. The idea is to reduce glare and improve visibility at night.
- I’m sleepin’ here: A new study of traffic noise levels in and around Atlanta found that almost 10 percent of the area’s population is exposed to traffic noise at a level described as “annoying.” And more than 2 percent live where traffic noise was described as “highly disturbing to sleep.”
Video bonus: How maddening are phantom traffic jams, you know, when everything slows to a crawl for no apparent reason? Here are two explanations, one from scientists, the other more like what we imagine.
