Men’s Journal: Tether Is a Trail of Shady Deals and Shattered Promises. Too Bad Cryptocurrency Now Depends on It

CAS PIANCEY could feel his heart pounding as the elevator doors slid open onto a tiled corridor of the eighth floor of the K Wah Centre. He was sweat-grimed and wrung out after a day of scouring Hong Kong for traces of a mysterious corporate entity. This was his final stop. Ahead lay a door marked “Proxy CPA Co. Ltd.” Piancey reached for the buzzer, then paused. What if the people he was chasing were really here—and understood what he was after?

It was September 2018, and Piancey, a cryptocurrency journalist, had flown from Los Angeles on a hunch. (“Piancey” is a pseudonym; doxxing is an occupational hazard best conducted anonymously.) He suspected that a handful of very clever and not particularly scrupulous people had come up with a way to create money in any quantity at the stroke of a keyboard—artificial electronic dollar bills that could be swapped for the real stuff. If he was right, these people were pulling off the swindle of a lifetime, a scam that would dwarf Bernie Madoff’s Ponzi scheme. If he was wrong, he owed some serious apologies.

Piancey pressed the buzzer. A Chinese woman in her 40s appeared. “Hello, can I help you?”

“I’m looking for Tether. This is the listed address. Is this Tether?”

“No, no,” she shook her head. “I have never heard of Tether. Sorry.” She disappeared.

And there it was. A company that supposedly held $3 billion in assets didn’t have a real office. Continue reading Men’s Journal: Tether Is a Trail of Shady Deals and Shattered Promises. Too Bad Cryptocurrency Now Depends on It

New York: How to Make Carbon-Neutral Gasoline Out of Thin Air

In a clearing on the edge of the Black Forest in southern Germany, a modified shipping container painted an immaculate white sits near a field of solar panels. Inside, ducts wrapped in insulating foil elbow between racks filled with cabinet tanks. Everything is motionless and silent, except for a soft whirring and humming. Michael Klumpp, a postdoc at the Karlsruhe Institute of Technology, turns a spigot and a clear liquid flows into a glass flask. The substance smells faintly of warm wax. Though it resembles oils derived from plants or petroleum, it does not come from any familiar source, but has literally been pulled from the thin air, transubstantiated from gas to liquid with the help of renewably generated electricity. On a mass scale, it could be used to fly airplanes or power heavy machinery, replacing petroleum in some situations. It even has a catchy name: eFuel.

The idea of turning air into liquid fuel may sound fantastical, but the underlying principle is as mundane as a head of lettuce. “It’s the same thing that plants do with photosynthesis,” says Roland Dittmeyer, leader of the project and director of the Institute for Micro Process Engineering at KIT.

While the machine that I watched produce that energy-dense liquid in the forest clearing is just the first stage of a pilot program, the underlying technology could help reshape the battle against climate change. Continue reading New York: How to Make Carbon-Neutral Gasoline Out of Thin Air

Businessweek: Underwater Drones Nearly Triple Data From the Ocean Floor


Last November a small seabed-exploration company out of Houston called Ocean Infinity made the discovery of a lifetime–or so it seemed, until it made another three months later. First, Ocean Infinity successfully located the remains of the San Juan, an Argentine navy sub that had vanished while on patrol. Then it found the wreck of the Stellar Daisy, a South Korean bulk ore carrier. Both vessels had been missing for more than a year, which often means a wreck won’t ever be found. The two-year-old company’s secret was teamwork: a set of eight drone subs working in tandem to scan a much larger area in record time.

These successes could be part of a broader shift in how humanity understands the sea. We know far more about the surface of Mars than we do about the bottom of the ocean, but seabed-scanning technology is growing sophisticated enough to render the inky depths much more transparent. Seabed 2030, a joint project of two nonprofits, aims to map the entire ocean floor by its namesake year. Key to that effort is Kongsberg Maritime AS, the Norwegian company that made Ocean Infinity’s subs.

Bjorn Jalving, senior vice president of Kongsberg’s subsea division, says the Hugin, its flagship drone, is a testament to advances in robotic strength and stamina. Hugins can dive as deep as 20,000 feet and stay underwater for 72 hours at a stretch. Costing $5 million to $10 million apiece depending on the onboard instruments they have and the depths they can handle, the drones are hardy enough, Jalving says, that “you let them out in the ocean, and you know that they’ll come back.” They’re also packed with sensors, including sonar that can cover five times the area of models from a decade ago, with 10 times the detail.

The subs can also transfer, process, and share much larger amounts of data with distant control centers than was possible before. Five years ago, Fugro NV, the Dutch survey and geosciences company responsible for searching the Indian Ocean for the downed Malaysia Airlines Flight MH370, relied on crewed survey boats that towed sonar gear on long cables up and down the seafloor as shipboard analysts monitored incoming data. Today the company streams field data to command centers onshore and plans to do away with some crews entirely.

Since 2017, Seabed 2030 has single-handedly increased the percentage of the seabed that’s been surveyed from 6% to 15%, mostly by compiling data from the likes of Fugro and Ocean Infinity. Fugro keeps mapping even when it’s moving ships between jobs. Beyond potential benefits such as finding clearer routes for undersea internet cables or energy pipelines, the extra intel will help answer big scientific questions related to climate change, says Larry Mayer, who contributes to Seabed 2030 as director of the Center for Coastal & Ocean Mapping at the University of New Hampshire. “How heat is distributed has to do with currents, and where those currents go is determined by where there are ridges and valleys and things,” he says. “It’s the most fundamental information that we can get.”

Just as the first sequencing of the human genome led to businesses sequencing many other people’s genomes, seabed mapping could one day become routine, or even just an ongoing process, helping to track things such as pollution, ocean warming, and fish stocks. “It will enable the world’s decision-makers to sustainably manage the oceans,” Jalving says.

For now, though, the oceans are keeping a great many secrets. After Fugro failed to find MH370, Ocean Infinity gave the search a shot last year, scanning 43,000 miles in five months—about 15 times the pace in 2014. That team, like Fugro’s, found nothing.

Businessweek: Addiction to a Language-Learning App Can Be Good for You

ReCaptcha inventor Luis von Ahn introduced Duolingo in 2012, hoping to help users master a new language. In minutes a day, the app promised, you could learn English, Spanish, French, or German—no books required, no instructors. And all for free.

The pitch sounded convincing enough. But in the first year after its debut, Duolingo had a hard time persuading hopeful linguists to keep up with the lessons. For every eight users who downloaded and tried Duolingo, seven never returned.

So von Ahn set out with his developers to make the app as addictive as Candy Crush and other popular games—in a good way. The addiction Duolingo cultivates, he says, isn’t harmful in the way the World Health Organization says compulsive video-game playing is; the organization classifies excessive video-gaming alongside opioid or amphetamine abuse. Duolingo really is about self-improvement, von Ahn says—time otherwise spent playing games, on social media, or doing nothing, is applied to developing a skill. What’s so bad about that?

Good or bad, Duolingo’s addiction rate is way up. Next-day retention is 55 percent, up from 13 percent in 2012. “That’s about as good as a middle-of-the-road game,” von Ahn says. And with about 300 million users, Duolingo is the largest language-teaching company in the world, by user base.

Businessweek: This Thiel-Backed Startup Says It Can Clean Up the Seas. Scientists Have Doubts

Boyan Slat, a Dutch 23-year-old who’s collected $30 million for his plastic-removal startup, is ready to test Ocean Cleanup’s System 001 prototype, but he hasn’t assuaged his expert critics.

Of all the things San Francisco has brought into the wider world, few have been as big and curious-looking as Ocean Cleanup’s System 001, the contraption an offshore supply ship towed to sea through the Golden Gate last month. Black, snakelike, and 2,000 feet long, System 001 was beginning a slow 1,300-mile journey to a remote garbage patch in the Pacific Ocean. When it arrives in mid-October, it will spend a year drifting around and around in a circular current, gathering as much plastic as possible, like a gigantic pool skimmer.

The idea can be attributed to Boyan Slat, a slight, 23-year-old Dutchman of Croatian descent who wears his curly brown hair in a mop and favors sunglasses made of recycled plastic. He says he became concerned about ocean debris when he was 16, scuba diving off the coast of Greece. In the intervening seven years, with the help of a viral explainer video, he’s raised more than $30 million from Inc. co-founder Marc Benioff, Palantir Technologies Inc. co-founder Peter Thiel, and others to try to prove that setups such as System 001’s can, in great enough numbers, help rid the ocean of plastic by 2050.

There’s just one problem, say ocean scientists: The device can’t possibly work on the scale imagined, and it could end up becoming just another piece of litter in the ocean. “People think that it’s an easy, sexy solution, but it’s not,” says Kim Martini, an oceanography postdoc at the University of Alaska at Fairbanks. Given that only single-digit percentages of the plastic entering oceans each year wind up in the garbage patches, “it’s clear that the problem is much bigger than what we’re able to solve,” admits Ocean Cleanup spokesman Joost Dubois.

Slat says Ocean Cleanup has conducted extensive modeling and prototype testing and that the outcry from his more credentialed peers (he dropped out of college) just proves he’s on to something. “If you don’t have any critics, it means that what you’re doing is easy and obvious,” he says.

New York: Coding Kids

coding131202_katie_wenger_250The doorbell rings, and Katie Wenger, 13, leaps up from the family dinner table and throws open the front door. On the stoop of her family’s building in Chelsea stands a 26-year-old Yale graduate named Allison Kaptur. Formerly a financial analyst, Kaptur quit to teach herself how to program and now works as a facilitator at Hacker School, a “writers’ retreat for programmers,” with a sideline as a coding tutor. The two descend the stairs to a basement study, and Katie shuts the door. “I’ve got exciting news,” she says. “I’m going to launch a start-up! It’s called Let Us.”

“What will it do?”

“It’ll be like Chatroulette, but connected to Facebook.” Katie describes her concept for an online environment in which strangers can randomly meet and either just chat or interact educationally as student and teacher. Kaptur nods. “Okay,” she says. “A little later, we can talk about the pieces we would need to make that work.”

For most people, software programming’s social cachet falls somewhere between that of tax preparation and autism. But it’s catching fire among forward-thinking New York parents like Katie’s, who see it as endowing their children both with a strategically valuable skill and a habit for IQ-multiplying intellectual rigor. According to WyzAnt, an online tutoring marketplace, demand for computer-science tutors in New York City has doubled each of the past two years. And if one Silicon Alley–backed initiative pans out, within a decade every public-school kid in the city will have access to coding, up from a couple of thousand.

Distant Tracks

A striking visual echo between two very different things:

The image on the left was taken by the Mars Reconnaissance Orbiter, a NASA spacecraft orbiting Mars. (I found it here.) It’s a zoom-in from outer space, showing the newly arrived Curiosity rover shortly after it began trundling around on the surface of the Red Planet. As a science fan, I find it incredibly wonderful that we not only have a brand-new mobile lab roaming Mars, but we can look down on the surface from orbit with telescopes so powerful they can make out the rover and even the twin tracks it has left behind in the soil. In this image Curiosity has just left its touchdown spot; the bluish (false color, btw) splotch to the lower right is where the “sky hook” retro rockets have blasted away the dust from the underlying bedrock. What we have, in essence, is a story in a single image — the arrival of a visitor to a distant planet, and the beginning of its exploratory career.

The image to the right shows another wanderer and its strikingly similar set of tracks. It’s a little hard to read, so here’s a rendering of the tracks alone, without all the extraneous background detail:

Here we see not the beginning of a journey, but the end.  The circle to the left is the fossilized remains of a horseshoe crab very much like the kind that wash up on beaches today. Some 150 million years ago, during the reign of the dinosaurs, this individual got swept by a wave out of the ocean and into a stagnant lagoon. The water there had no oxygen, so the clock was ticking. The creature managed to scurry along the muddy bottom for 32 feet before expiring. Apparently it’s not entirely unusual for fossilized horseshoe crabs to turn up alongside traces of their final steps; what’s special about this one is that this particular set of tracks tells an entire story, from the disturbed area of mud where the wave deposited the beast, to the meandering course it took as it sought to escape, to its moment of death. To see the whole set of tracks, and read a more detailed story, click here.

What I love about these pictures is how similar they seem, though they represent two very different kinds of wanderers, separated by hundreds of millions of years and hundreds of millions of miles. Nabokov famously opined that true literature can be recognized as a thing that creates an “indescribable tingle of the spine.” What tends to be overlooked, it seems to me, is that science can create that same feeling.

Facebook’s Fatal Flaw

Given the fact that Facebook just filed for a public offering of its shares which will value the company at $100 billion and make thousands of its current investors wealthy beyond imagination, you might be forgiven for thinking that Facebook is a wild success. That, and the fact that some 800 million people currently use Facebook, or more than 10 percent of the total world population.

But despite all that, I think that Facebook is failing.

Do I think that Facebook is going to go bankrupt tomorrow? Far from it. I’m sure that it will continue to print money for years to come, based on sheer momentum alone. (Hey, AOL still exists.) But if you listen to the way that people talk about Facebook you sense – or at least I do – that its cultural moment has passed. This is just based on a very unscientific analysis of my own very small circle of acquaintances, but once upon a time, Facebook was this awesome cool thing that you just had to try. Lately, all everyone seems to say about Facebook is “I don’t get it” or “I find it annoying but I feel like I have to go on once in a while.” Facebook, in other words, is heading the way of MySpace.

Becoming MySpace, of course, is the specter that haunts the nightmares of every Facebook investor. The company has been super aggressive in trying to avoid that fate by trying to metastasize into something grander than an automated blogging site, sending out tentacle everywhere in order to become a ubiquitous presence that binds together every aspect of the internet experience. They have striven for immortality through intrusiveness. And this, I think, will be their undoing. Continue reading Facebook’s Fatal Flaw

How GPS Makes Clueless Drivers

We were driving somewhere in central New York State, along a two-lane blacktop that wound a spectacular course through farm-dotted valleys, past placid lakes and along forested hillsides.  My brother’s attention, though, was on the unwavering purple line on the dashboard-mounted GPS unit. At last we reached the interstate on-ramp – and he drove right past it. “Turn left in 50 feet,” the GPS said. My brother obeyed, hanging a left onto the access road. According to the machine we were smack on the highway, yet here we were, stuck behind a tractor pulling a load of hay. “Time to destination, 30 minutes,” the GPS announced.

As we idled along behind the cloud-belching agriculture machinery, I had a feeling of déjà vu. Not for this exact moment of farm-machinery-induced frustration, but for that hot moment of clarity when you realize that you’ve been suckered by the self-assurance of modern technology.

It’s something I find happening more and more often. In the 25 years I’ve been a travel writer, the information revolution has changed everything. Once, we visited travel agents, bought paper maps, consulted destination guides. Now, all of those needs can be taken care of by a few flicks of a finger across a phone’s touch screen. Because information is so cheap, we don’t need to pay much attention to it. We can browse around the world the way we browse around the web.

Apps and gadgets of every kind allow us to summon instant expertise that otherwise would have required years of study. But they also remove the need to learn, to engage, and to be curious. We can ignore context. And so even when we know exactly where we’re located, we have no idea where we are.

Pilots have a word for the state of presence in the world around you; they call it situational awareness. “Keep your eyes out of the cockpit,” my flight instructor always used to tell me. Meaning: look at the world around you. Don’t get fixated on what your instruments are telling you. Understand the context of what you’re seeing. Situational awareness means understanding where things are in relation to one another.  It means knowing what’s going on, and what you can do when your plans start to unravel.

Electronic gadgets, in contrast, urge us to forget all that tiring mental work and just follow the purple line. They’re the mental equivalent of the electric scooters that obese people ride around at amusement parks to save themselves the effort of walking. Continue reading How GPS Makes Clueless Drivers

Could a Sendai-sized Earthquake Hit the US?

The massive tremors and ensuing tsunami that devastated Japan earlier this month was an order of magnitude more destructive than anything that has hit the continental Unites States in historical times. But seismologists say that a similar event could well strike here. In fact, it’s only a matter of time. And compared to Japan, we’re far less prepared to deal with the consequences.

The danger zone is not California. While Los Angeles and San Francisco suffer frequent damaging quakes, they owe their seismic woes to a relatively shallow phenomenon called a slip-strike fault, caused by two tectonic plates sliding against each other. Sendai was a result of something far more dangerous: a so-called subduction zone, a deep-lying discontinuity caused by one plate slowly burying itself under another.

In both cases, earthquakes are caused by the slow building of pressure as the two plates move relative to one another, but remained locked together at the fault line. The strain increases steadily until the fault gives way, releasing the energy in the form of an earthquake. While strike-slip faults are relatively shallow, a subduction fault is deeper and can release a lot more energy. “One of the signatures of this type of fault,” says Mike Blanpied, associate director of the US Geological Survey’s Earthquake Hazards Program, “is that they sit quietly until they create a giant quake.”And by giant, he means monster. The Sendai event contained more than 30 times the energy of the San Francisco Earthquake of 1906.

Only one such region lies within the Lower 48. Continue reading Could a Sendai-sized Earthquake Hit the US?
