How we built a less-explodey lithium battery and kickstarted the EV revolution
For the final installment of Hitting the Books for 2023, we're bringing you an excerpt from the fantastic Material World: The Six Raw Materials That Shape Modern Civilization by Ed Conway.
HP's 'Copper' VR headset will boast extra-sharp displays
HP is working on a new virtual reality headset, which will be a part of Microsoft's Mixed Reality program, according to a report from Road to VR. The headset, codenamed Copper, is still being developed but promises a high-resolution display and a more comfortable, ergonomic design than the company's previous models.
Verizon policy: switch from copper to fiber, or no fix for you
It won't shock you to hear that Verizon is not so fond of copper phone lines (just ask those left out in the cold after Hurricane Sandy), but it's now clear exactly how the carrier plans to make you ditch those old wires. The Philadelphia Inquirer has obtained documents detailing a longstanding "Fiber is the Only Fix" policy that effectively forces you to move to a fiber optic connection if you want assistance. If you ask for repairs on copper phone service in an area where fiber is available, technicians are supposed to tell you that the only remedy is to move to the newer technology. Decline, and you won't get any help -- Verizon's official stance is to refuse repairs on copper.
Phone companies ditching copper wires will have to follow the rules
The age of the copper land-line is nearing its end, but traditional phone lines aren't going quietly: new rules from the FCC now require service providers notify customers of the impending removal and drawbacks of switching to a VOIP line three months before killing a copper network. It sounds like a reasonable move -- customers need to know that the technology replacing their traditional land-line won't work during a power-outage without an external power source -- but not everybody at the FCC is happy with the new rules.
BT's latest broadband trial will more than treble download speeds
For the fastest broadband speeds, you normally need fibre optic cables running directly into your home. While that's still the perfect solution, BT will soon be trialling a new technology that could give those on copper a much-needed speed boost. Fibre To The Distribution Point (FTTdp), commonly referred to as "G.fast," uses a wider frequency band to increase data speeds over copper. It works best over short distances, so usually a node is required somewhere between the cabinet and your home to extend the reach of the faster fibre. As ISPreview reports, BT is beginning its first residential trial next month in Huntingdon, Cambridgeshire, with Gosforth, Newcastle and Swansea to follow. It should be able to deliver "a few hundred megabits per second" at first, although BT says 500 Mbps should be achievable in the future. Given Fibre To The Cabinet (FTTC) normally tops out at 80 Mbps, this will be a huge jump for households still waiting on full-blown fibre.
Apple's Beats-based music service may come with an iOS 8 update
You might not have to wait that long to try Apple's rumored Beats-based streaming music service. Tipsters tell 9to5Mac that the folks in Cupertino are "currently considering" a launch for the all-you-can-hear offering in tandem with iOS 8.4, rather than holding off for iOS 9 or later. This new software would supposedly arrive some time after the Apple Watch release in April. That may still sound distant, but Apple just gave developers its first iOS 8.3 beta (yes, even before 8.2 has shipped) -- if 8.4 happens at all, it's on a fast track.
BT says faster broadband is coming, but it could take 10 years
Everyone in the UK wants super-fast broadband in their home. The most reliable and effective solution right now is fibre, which every internet provider uses as the backbone for their network nationwide. But there's a problem -- the fibre often stops at the street cabinet, and many customers are limited by the slower copper cables running up their driveways. While fibre can be installed for the final leg, it's expensive, so companies such as BT are looking for new ways to give their traditional copper a speed boost. One approach is "G.fast," a technology that uses a wider frequency band to increase performance. It works best over shorter distances, although rural homes can still be supported via remote nodes and distribution points, which bring the fibre connection closer to the property.
Researchers get record broadband speeds out of old-school copper wire
While telecoms companies around the world are investing millions into the development of fiber-optic networks, the standard copper telephone line may still have some life in it yet. Experts at Alcatel Lucent's Bell Labs research division are claiming a new world record by achieving super-fast speeds through the aging technology. Researchers were able to achieve 10Gbps speeds with the same cables you'd find under many residential streets.
Onkyo's latest headphones add iOS controls to their posh copper cables
Does the choice of metal inside a headphone cable have much discernible impact on sound quality? It's a debate we'd struggle to contribute to, with ears as bruised as ours, but Onkyo clearly believes that such things matter. Its latest over-ears (the ES-CTI300) and in-ears (IE-CTI300) come with the company's first "super-conductive," oxygen-free 6N copper cable to include in-line controls for music and calls on iOS devices. The translucent cable is detachable, so you can switch it out if it gets damaged or if you'd prefer the older, seamless 6N cable (which has no controls) or the flat anti-tangle cable instead. Other specs are pretty much on a par with Onkyo's existing range, with the on-ears having 40mm titanium drivers tucked inside aluminum ear-cups, and with the in-ears using 14.3mm drivers inside hybrid aluminum/ABS resin enclosures. We're waiting to hear on US availability, but Brits should expect to find these products in stores from December, priced at £200 and £150 for the bigger and smaller pairs respectively. Oh, and depending on your own level of bruising, you might want to try them with Onkyo's new iOS app, which lets you play your iTunes library through a touch-adjustable equalizer that claims to have 16,000 discrete bands, no less.
LG Chem develops very flexible cable batteries, may leave mobile devices tied up in knots
The world is no stranger to flexible batteries, but they've almost always had to be made in thin sheets -- that doesn't amount to a long running time if you're powering anything more than a watch. LG Chem has developed a flexible lithium-ion battery that's not just better-suited to our bigger gadgets but could out-do previous bendable energy packs. Researchers found that coating copper wires with nickel-tin and coiling them briefly around a rod results in a hollow anode that behaves like a very strong spring; mating that anode with a lithium-ion cell leads to a battery that works even when it's twisted up in knots. Join multiple packs together, and devices could have lithium-ion batteries that fit many shapes without compromising on their maximum deliverable power. Some hurdles remain to creating a production-grade battery, such as a tendency for the pack to shed a small amount of capacity whenever it's put under enough stress. LG Chem is fully set on turning these cable batteries into shippable technology, however, and could ultimately produce mobile devices and wearables that really do bend to their owners' every whim.
IBM alliance sets efficiency record for solar power cells using common materials
There have been more than a few solar power efficiency records set in the past few months, let alone years. What makes IBM, DelSolar, Solar Frontier and Tokyo Ohka Kogyo think they can just waltz in and claim a record of their own? By using more commonplace elements in the periodic table, that's how. The partnership's new photovoltaic cell based on copper, zinc and tin (CZTS for short) can convert light rays to electric power with a 11.1 percent efficiency rate -- still nothing to upset traditional silicon power, but a large 10 percent more efficient than anything else in the class. In its early form, CZTS can already be manufactured through ink printing and could be produced in quantities equivalent to about 500 gigawatts of power per year, or five times more than some of the next-closest alternatives. The group wants to improve CZTS' efficiency over the course of the next several years, ideally reaching the point where it's useful as a truly cheap, ubiquitous source of power. We're looking forward to the day when there's a little slice of solar energy in just about everything, hopefully including a few more hybrid cars and private aircraft.
The Queue: It's been a long time since we faced Jaraxxus
Welcome back to The Queue, the daily Q&A column in which the WoW Insider team answers your questions about the World of Warcraft. Mathew McCurley (@gomatgo) will be your host today. Still the best Mr. Voletron song. Link Thorim all you want -- you know I'm right. MattressWX asked: Do you think Blizzard will ever get rid of the requirement of being in a raid group in order to enter a raid instance? It would be nice to solo old content without having to ask someone to group with you just to get in the door. No only do I hope that Blizzard gets rid of the requirement for raid groups, especially for old raids that we can solo, but I hope that Blizzard gets rid of some of the heroic lockouts for doing Burning Crusade and Wrath content more than once a day. Farming for certain transmog weapons and specific pieces is a pain in the butt when you've got one shot at the boss a day.
Copper-nickel nanowires from Duke University could make ubiquitous printable circuits
Nanowires, although they're building steam, still have to overcome the not-so-small problem of cost -- they often have to use indium tin oxide that's not just expensive, but fragile. Duke University has developed copper-nanowire films that could remedy this in style. The choice of material is both a hundred times less expensive to make than indium and is much more durable. It's flexible, too: if layered on as a coating, the nanowires would make for considerably more viable wearable electronics that won't snap under heavy stress. The catch, as you might suspect, stems from the copper itself, which doesn't conduct as much electricity as indium. The nickel will keep your copper electronics from oxidizing faster than the Statue of Liberty, however. Any practical use could be years away, but further successes from Duke could quickly see printable electronics hit the mainstream power and power our dreams of flexible displays.
Dell begins test deployment of ARM-based Copper servers
Back in February, Dell revealed its intentions to enter the ARM server field. Today, the company announced that it is shipping ARM-based Copper servers to a limited number of customers. Copper is lower power than x86 servers, and Dell thinks this makes it a good fit for energy-intensive platforms such as Hadoop. In that same vein, the company views Copper as a cost-effective option that can be used for light workloads and for testing performance. In addition to deploying its new servers to select clients, Dell will be looking to the open source community for help in further developing its ARM system (the platform currently runs Linux). No word on when Copper will move beyond the testing phase.
The NOFAN CR-95C: a fanless copper CPU cooler for your next-gen build
Interesting times to be shopping around for a processor, but what about a new cooler to go with it? This unassuming little work of art is the copper special edition of the NOFAN CR-95C, which is rated to cool CPUs of up to 100W TDP without the need for a fan. Judging from all the Intel and AMD leaks, that level efficiency ought to have you covered regardless of whether you opt for Ivy Bridge or Trinity -- so long as you don't mind hanging around until June, because FanlessTech reckons we won't see it go on sale any sooner.
NC State researcher finds more efficient way to cool devices, looks to cut costs too
Does your electronic device have you a bit hot under the collar these days? A researcher at NC State has developed a faster and less expensive method for cooling gadgets -- especially those that tend to crank the heat up. Dr. Jag Kasichainula, an Associate Professor of Materials Science and Engineering, authored a paper on the research that implements a "heat spreader' composed of a copper-graphene composite and an indium-graphene interface film to cool devices. Because the two materials exhibit a high thermal conductivity, they allow the device to cool more efficiently while distributing said heat -- 25 percent quicker than the pure copper in many pieces of tech. And if that wasn't enough, the research also details the process for creating the composite using electrochemical deposition. "Copper is expensive, so replacing some of the copper with graphene actually lowers the overall cost.," Kasichainula notes. If you're itching to read a full rundown of the findings, the full text can be accessed via the source link below.
Huawei hurls Gigabit broadband across 100 meters of old copper
There's little point in having a super-speedy optic backbone if broadband gets yellow-flagged on the final straight between junction box and home. But Huawei claims it's developed prototype DSL technology that can deliver 1Gb/s downstream and upstream over common twisted pair copper telephone cable for distances of up to 100 meters. This could provide a "cost effective option for telecom operators building ultra-broadband access networks," but will it be enough to overcome America's anxiety towards Chinese-made telecoms infrastructure? In any case, some lucky people have had fiber-to-the-home Gigabit broadband for months already.
More efficient heat sinks could sport nanowire whiskers
Sintering is a common process for creating copper heat sinks that involves packing powdered metals into a particular shape and baking it in a vacuum. A funny thing happens though, if you leave out the vacuum part of the equation: you don't get a solid shape, but a porous pile of particles with hollow, nanowire whiskers sticking out of it. The serendipitous discovery could lead to a new way to make heat sinks for everything from CPUs to boilers at power plants. Now researchers at MIT are trying the process with practically every material they can get their hands on. Of particular interest is zirconium, which could be used with fuel rods in nuclear reactors to improve efficiency. The idea of whisker-covered heat sinks may sound strange, but the potential for improving thermal management across a range of applications is huge. Just don't try and pet it -- these things tend to get a little toasty.
Elderly Georgian lady disconnects Armenian internet for half a day... by accident
A 75-year old lady from Georgia (the country, not the state) has perpetrated an impressive feat of international sabotage in what seems to have been an accident of extremely bad luck. While foraging for copper wire near her home in the village of Ksani, the unnamed septuagenarian managed to come across a critical fiber optic cable, one responsible for serving internet connectivity to "90 percent of private and corporate internet users in Armenia" and some in her own country as well. Her swift strike at the heart of said bit-transferring pipeline resulted in all those folks being thrown offline for a solid 12 hours, while the Georgian Railway Telecom worked to find and correct the fault. In spite of her relatively benign motivations, the lady now faces three years in prison for the damage she caused. We'd say all's well that ends well, but this doesn't actually seem like a very happy ending at all.
Just say no: Apple and Intel stop using conflict minerals
While the US government hasn't issued an outright ban against the use of 'conflict minerals' coming from the Congo, it has passed a law that will require companies who use them to tell all of us when our gadgets have been paid for (in part) with blood. Looks like Apple and Intel weren't too keen on the bad PR that would come from such disclosures, and joined the Electronic Industry Citizenship Coalition and its Conflict-Free Smelter program. The program requires mineral processing plants either prove that they don't fund the ongoing hostilities in central Africa or peddle their war-supporting wares elsewhere. For now, that means that the folks in Cupertino and Santa Clara will have to find other sources for the three Ts (tungsten, tin, and tantalum) needed to sate our technological appetites.
