Lifetime lithium-ion in view as serendipity uncovers way to make it happen for clever student:

Scientists can now make lithium-ion batteries last a lifetime – Computerworld

The discovery could lead to vastly longer lifespans for batteries in computers, smartphones, appliances, cars and spacecraft

Who says playing around is a waste of time?

Researchers at the University of California at Irvine (UCI) said that’s exactly what they were doing when they discovered how to increase the tensile strength of nanowires that could be used to make lithium-ion batteries last virtually forever.

Researchers have pursued using nanowires in batteries for years because the filaments, thousands of times thinner than a human hair, are highly conductive and have a large surface area for the storage and transfer of electrons.

The problem they have encountered, however, is that nanowires are also extremely fragile and don’t hold up well to repeated discharging and recharging, known as “cycling.” For example, in a typical lithium-ion battery, they expand and grow brittle, which leads to cracking.

UCI doctoral candidate Mya Le Thai solved the brittleness conundrum by coating a gold nanowire in a manganese dioxide shell and encasing the assembly in an electrolyte made of a Plexiglas-like gel. The combination, they said, is reliable and resistant to failure.

Energy Letters
Gold nanowires were surrounded by an electrodeposited layer of Plexiglas-like gel called propylene carbonate, which has a thickness of between 143 and 300 nanometers. Identical capacitors without the gel show cycle stabilities ranging from 2000 to 8000 cycles. With it, the nanowires stood up to 200,000 recharges.

The findings were published today in the American Chemical Society’s Energy Letters. Hard work combined with serendipity paid off in this case, according to senior author Reginald Penner.

“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” Penner, chair of UCI’s chemistry department, said in a statement. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”

“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most.”

The researchers believe the gel plasticizes the metal oxide in the battery and gives it flexibility, preventing cracking.

Thai, the study’s leader, cycled the nanowire-enhanced electrode up to 200,000 times over three months without detecting any loss of capacity or power and without fracturing any nanowires.

“All nanowire capacitors can be extended from 2000 to 8000 cycles to more than 100,000 cycles, simply by replacing a liquid electrolyte with a… gel electrolyte,” the researchers wrote in their paper.

The result: commercial batteries that could last a lifetime in computers, smartphones, appliances, cars and spacecraft.

“The coated electrode holds its shape much better, making it a more reliable option,” Thai said in a statement. “This research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality.”

Why vinyl, why old? Nostalgia or something better?

Come on don’tcha love them – take them out of the bottom drawer! Graphic by Ellen Weinstein for NYT

Here’s an interesting think piece exploring the fruitful topic of why old tech hangs on and eventually makes some kind of comeback in many uses. Examples might include the celebrity fashion for flip phones (which avoid hacking unlike smartphones) and old digital cameras as well as film, which impose slow photography levels of choice and discrimination on photographers who otherwise flail away with machine gun repetition in the hope they will (and often do) capture shots they would otherwise never shoot.

More than 571 million print books were sold in the United States in 2014. About 55 million newspapers still land on doorsteps every morning. As for those vinyl records, 13 million LPs were sold in 2014, the highest count in 25 years

Why Vinyl Records and Other ‘Old’ Technologies Die Hard

For a glimpse of what teenagers are into these days, all you have to do is visit Abbot Kinney Boulevard in the Venice neighborhood of Los Angeles. On weekend nights, the half-mile shopping drag is packed with style-conscious kids who traipse past coffee shops, ice cream parlors and boutiques, often while taking selfies.

Yet one of the most popular destinations for these teenagers is a white, single-story building with big pink letters on the roof that spell “Vnyl.” The store sells vinyl records, and the kids who gather there are often in awe.

“I’d say half of the teens who hang out in my store have never seen a record player before,” said Nick Alt, the founder of Vnyl. “They will walk up to the turntable, and they have no concept where to put the needle.” But once they figure out that the needle goes into the outermost groove, those smartphone-toting teenagers are hooked.

Whenever a new technology comes out, we often believe it will make an older technology obsolete. As a reporter who has been covering technology for The New York Times for more than a decade, I’ve made such proclamations, saying that the iPad would kill the Kindle (I later realized the error of my ways, and now own both), that eBooks would be the death of print (I later reversed myself, several times), and that driverless cars will make driving passé and allow us to nap in the front seat (this has yet to be disproved).

But what I’ve come to realize is that while the new thing gets people excited, the old thing often doesn’t go away. And if it does, it takes a very long time to meet its demise.

Just look at film cameras. You would think they have been vanquished from the planet, but millions of people still use them. In 2012, more than 35 million rolls of camera film were sold, compared with 20 million the year before.

And while Polaroid has filed for bankruptcy (twice) in the age of digital cameras, the company is making a resurgence (again). One of Polaroid’s largest growing demographics, surprisingly, is teenagers who want a tangible photo but also don’t want to wait. (Polaroid has also become the go-to camera for people who take nude photos and fear that their phones could be hacked.)

Other types of physical media have also held on.

More than 571 million print books were sold in the United States in 2014. About 55 million newspapers still land on doorsteps every morning. As for those vinyl records, 13 million LPs were sold in 2014, the highest count in 25 years, according to the Recording Industry Association of America. (Records are also one of the few growth areas for the beleaguered industry.)

So why does old tech survive and, in some cases, undergo a revival? For some consumers, it’s about familiarity (e.g., newspapers and print books), while for others, it’s about nostalgia (e.g., record players and film cameras).

For example, I’ve been taking photos for over 25 years, and what made me fall in love with photography was the dirt, grit and grime of film (I used to shoot with Tri-X 3200 for the film nerds out there). And as much as I love my digital cameras, I’ve been shooting with film again to capture some of that visceral quality I no longer get with pixels.

The resurgence of old tech doesn’t stop with physical media.

For example, tens of millions of Americans still own a landline; millions of USB thumb drives are still being used, even though you can store anything in the cloud free; and people still use and buy tens of millions of flip phones every year, including such notables as Mayor Bill de Blasio, Anna Wintour, Warren Buffett, Iggy Pop and Rihanna. Pagers also never completely died.

You’ve probably heard the saying that the minute that you drive a car off a dealer’s lot, it loses value. Well, that is no longer true for old cars. Some vintage cars have increased in value by 500 percent. (One reason for this is that younger car owners want to be able to fix and tinker with their own cars. Try doing that with a Tesla, and you’ll void the warranty.)

Of course, there are some outdated technologies that die a fateful death and never return. I don’t know many people with a dedicated car phone, for example. (Though I’m sure some hipster just posted one to Instagram.)

To be fair, we have been wrongly predicting the demise of old technologies for some time. In 1876, for example, when The New York Times first wrote about the telephone, and later the phonograph, the writers of the day said that these devices would empty the concert halls and churches, as no one would ever want to leave home again.

And yet, just this month, Diplo held a concert for an estimated half-million people in Cuba. Something tells me that some of those people will also be buying the performer’s album on vinyl.

Serious stalking danger from an extension to Facebook Messenger is revealed in a recent geek post. The extension locates you within one meter ie which dorm, where in dorm, etc.

“However, everyone I have shown this extension to has been anywhere from surprised to appalled that this much of their very personal data is online for their friends (and even complete strangers) to access. So it is seems that there is an issue.”

Wonders from Aviation Technology: An IMAX Celebration

National Geographic Praises Flight Technology With Stunning Pictorial

Reminder of all that airplanes have brought, including world shopping and families back for Thanksgiving

But Isn’t This A Poignant Last Look at Earth at its Peak?

With its Smithsonian premiere tomorrow in Washington, New Yorkers will also now have a chance to catch probably the most resolutely positive documentary on air travel and its benefits ever made.

Living in the Age of Airplanes’ is a 47 minute IMAX, HD 4K digital, Dolby extravaganza of superb shots of the major scenic spots of the world, together with other benefits of the invention of the airplane, such as the flowers and myriad other household goods from half way round the world in every living room, which cranky passengers squeezed into narrow, unforgiving seats in late arriving aircraft never think of anymore.

Hail to the Airplane: Tourists thrill to an approaching plane landing over their heads on St Maartens.

Actually, the gifts of the airplane in this National Geographic special have never looked so good even to those who have actually visited them in person, but no matter. The aim of this all-too-brief, 48 min documentary is to remind us just what a remarkable transformation of human existence has been wrought in a blink of time’s eye by aviation, and it succeeds triumphantly. If anything, it is far too short.

Tourists walking on the sight seeing bridge at Brazil’s extensive Iguazu Falls (click to expand to very large size)

Covering all seven continents, from Iguazu Falls, the gigantic Brazilian set of waterfalls 1.7 miles long stretching into Argentina, to the Maldive Islands, where some brilliant shots are taken amid fish under the clear water as the floats of a seaplane take off the surface overhead.

The filmmakers are undeterred by remoteness or time. They manage to get a rare visit to the South Pole with cinematographer Doug Allan, the Polar wildlife specialist who had spent 30 summers in Antarctica but never reached the Pole, which demands perfect weather to coincide in three airports.

The DC-3 can land on skids in Antartica, but weather has to be fine in three airports to get you to the South Pole itself.

The DC-3 can land on skids in Antartica, but weather has to be fine in three airports to get you to the South Pole itself.

What they find there, on top of the two mile thick ice sheet, is a decorative pole and other ceremonial trappings from 12 nations that signed the Antarctic Treaty, in force since 1961. The marker is a barber pole with a mirrored sphere on top, and it now lies several hundred feet from true 90° south, since the ice cap shifts 30 feet every year, and moving the pole and the ring of national flags would be too much trouble. (The US station with its record size neutrino hunting IceCube particle detector is discreetly in the background).

Now you’ve got there, you may reflect that the Pole is 300 feet farther south. (Click twice to fully enlarge)

But many of the visuals are stunning, new shots of familiar locations and lesser known ones by cinematographer Andrew Waruszewski using the very cinematic, new digital camera Alexa and often accompanied by the overwhelming music typical of IMAX presentations as if vast natural beauty doesn’t speak for itself. Even the platform stretching over the Grand Canyon lends itself to emphasizing the grandeur of the chasm below.

The platform at the Grand Canyon is called the Skywalk (click to enlarge)

But the point the movie makes best is its basic theme, just how immense an acceleration of human life aviation has brought so quickly.

The timeline is, if you think about it, astonishing. For almost 200,000 years we walked at three miles an hour and most humans traveled less than 20 miles from their birthplace. The wheel arrived 5000 years ago, but the steam engine powered the wheel only 175 years ago, when we were still as separated by time and distance as the ancient Egyptians. On screen the map of the USA is lit up by glowing rail connections which networked the entire country by the end of the 19th Century.

Are you thinking of how overweight your neighbor is, or looking out of the window at more land than your ancestors saw in a lifetime? (Click twice for full size)

Then in only a century of aviation, and sixty years of the jet age, the entire globe is lit up with planes like fireflies – 100,000 takeoffs every day, 250,000 people in the sky at any one time. The cliches praising this transformation are all very true: Aviation is now “the lifeblood of the modern world”. The airport is “portal to the planet”. Now “it’s walking distance to almost anywhere”. “What once demanded migration is now a vacation.”

Somehow the pyramids don’t seem as evocative of the secrets of the past when Mum and kids are towed past on camels (Click twice to enlarge)

The film conveys the sense of wonderful mastery conveyed by this change, without delving into its other consequences. Some may privately feel that the Sphinx loses her mystery when a camel carrying Mum and children comes into view, and others worry about global warming and global disease, not to mention the original sin introduced by aviation, the civilian mass deaths of bombing. But this is a feel good trip to things we experience now without a second thought, but are really marvels of life in the age of the airplane.

“Since we were all born into a world with airplanes, it’s hard to imagine that jet travel itself is only 60 years old, just a tick on the timeline of human history,” says director Terwilliger. “Yet practically overnight, our perception of crossing continents and oceans at 500 mph has turned from fascination to frustration. I want to reignite people’s wonder for one of the most extraordinary aspects of the modern world.”

In this huge hangar in Amsterdam, flowers from Kenya will arrive and be sent to Alaska via another hub to reach an Alaska living room in a day, with ten days of fresh bloom left.

Plane passion

One reason may be that almost everyone important involved has access to what is now the best benefit of all, the freedom and adventure of flying small planes, for which they feel a personal passion. Funded by GE as the main sponsor, Terwilliger visited 18 countries over several years for this film, a dedication to the topic that arose first from his childhood awe at the performance of the Blue Angels. He made a 2008 film about this team of Navy jet pilots, Flying Full Circle, in which he himself flew in an F-18 Hornet. Filled with enthusiasm Terwilliger soloed at 19 and got his private pilot license a year later, and his first feature film in 2005 was One Six Right, which told of a day in the life of the local Van Nuys airport on Los Angeles.

The Maldives don’t have an airport but one of these pretty seaplanes can get you there directly.

Harrison Ford, also a keen pilot, narrates the film’s expertly written voice over, which compresses great historical trends as skilfully as Eugene Weber (the UCLA professor whose peerless history of Western society, Western Tradition, is still running on CUNY TV). The star keeps a small fleet of airplanes in a Santa Monica hanger, including a Bell 407 helicopter which he has flown to rescue Wyoming hikers. At 72 recently he had to crash land his vintage plane on a golf course, but survived with a gash to the head.

Not so wonderful: Harrison Ford’s engine failure after takeoff recently landed him on a golf course with a nasty gash in his forehead.

The composer, James Horner, who also pilots his own plane, contributes an appropriately stirring score which is only occasionally intrusive (he won two Oscars for Titanic, for the score and a song, ‘My Heart Will Go On’, and the album was the largest-selling instrumental score ever, at 10 million in the US and 27 million worldwide).

The airplane can take you to see the elephants in East Africa, but did anyone ask the elephants if we are welcome?

Living in the Age of Airplanes” will be showing at the Cradle of Aviation Museum, the National Geographic Leroy R. & Rose W. Grumman Dome Theater (Garden City, NY), and the New York Hall of Science in Queens. If busy New Yorkers can be persuaded to lift their eyes from their phones long enough to get their whole family there, it will give them a new appreciation of all that the airplane has brought to our lives, and perhaps inspire them to transcend the inconvenience of modern air travel and visit faraway places themselves before they all are submerged by the banality of mass tourism, or ultimately sink beneath the ocean rise of global warming.
