Consortium Roadmap Shows 100TB Hard Drives Possible By 2025 116

Posted by samzenpus
from the in-the-future dept.
Lucas123 writes An industry consortium made up by leading hard disk drive manufacturers shows they expect the areal density of platters to reach 10 terabits per square inch by 2025, which is more than 10 times what it is today. At that density, hard disk drives could conceivably hold up to 100TB of data. Key to achieving greater bit density is Heat-Assisted Magnetic Recording (HAMR) and Bit Patterned Media Recording (BPMR). While both HAMR and BPMR will increase density, the combination of both technologies in 2021 will drive it to the 10Tbpsi level, according to the Advanced Storage Technology Consortium (ASTC).

Jackie Chan Discs Help Boost Solar Panel Efficiency 155

Posted by samzenpus
from the super-solar-cop dept.
wbr1 writes Apparently the pit pattern on a blu-ray disk is great at helping trap photons, rather than reflecting them. Applying this pattern to the glass in a solar panel can boost efficiency by 22%. Researchers at Northwestern tested this system with Jackie Chan discs. From the article: "To increase the efficiency of a solar panel by 22%, the researchers at Northwestern bought a copy of Police Story 3: Supercop on Blu-ray; removed the top plastic layer, exposing the recording medium beneath; cast a mold of the quasi-random pattern; and then used the mold to create a photovoltaic cell with the same pattern....The end result is a solar panel that has a quantum efficiency of around 40% — up about 22% from the non-patterned solar panel."

WaveNET – the Floating, Flexible Wave Energy Generator 75

Posted by Soulskill
from the making-bernoulli-work-for-us dept.
Zothecula writes: Scotland's Albatern is putting a new, modular spin on renewable energy generation. WaveNET is a scalable array of floating "Squid" generator units that harvest wave energy as their buoyant arms rise and fall with the motion of the waves. Each Squid can link up to as many as three others, effectively creating a large, floating grid that's flexible in every direction. The bigger this grid gets, the more efficient it becomes at harvesting energy, and the more different wave movements it can extract energy from. Albatern's 10-year target is to have 1.25 kilometer-long floating energy farms pumping out as much as 100 megawatts by 2024.

Ask Slashdot: Why Is the Power Grid So Crummy In So Many Places? 477

Posted by Soulskill
from the it's-not,-the-power-company-just-hates-you dept.
An anonymous reader writes: I live in a relatively large college town that's within easy driving distance of several major metropolitan centers. In many ways, the infrastructure around here is top-notch. The major exception is the electrical grid. Lightning storm? Power outage. Heavy winds? Power outage. Lots of rain? Power outage. Some areas around town are immune to this — like around the hospital, for obvious reasons. But others seem to lose power at the drop of hat. Why is this? If it were a tiny village or in the middle of nowhere, it would make sense to me. What problems do the utility companies face that they can't keep service steady? Do you deal with a lot of outages where you live? I'm not sure if it's just an investment issue or a technological one. It hasn't gotten better in the decade I've lived here, and I can imagine it will only get worse as the infrastructure ages.

Is LTO Tape On Its Way Out? 272

Posted by Soulskill
from the IT-no-longer-caught-on-tape dept.
storagedude writes: With LTO media sales down by 50% in the last six years, is the end near for tape? With such a large installed base, it may not be imminent, but the time is coming when vendors will find it increasingly difficult to justify continued investment in tape technology, writes Henry Newman at Enterprise Storage Forum.

"If multiple vendors invest in a technology, it has a good chance of winning over the long haul," writes Newman, a long-time proponent of tape technology. "If multiple vendors have a technology they're not investing in, it will eventually lose over time. Of course, over time market requirements can change. It is these interactions that I fear that are playing out in the tape market."

How the World's First Computer Was Rescued From the Scrap Heap 122

anavictoriasaavedra sends this quote from Wired: "Eccentric billionaires are tough to impress, so their minions must always think big when handed vague assignments. Ross Perot's staffers did just that in 2006, when their boss declared that he wanted to decorate his Plano, Texas, headquarters with relics from computing history. Aware that a few measly Apple I's and Altair 880's wouldn't be enough to satisfy a former presidential candidate, Perot's people decided to acquire a more singular prize: a big chunk of ENIAC, the "Electronic Numerical Integrator And Computer." The ENIAC was a 27-ton, 1,800-square-foot bundle of vacuum tubes and diodes that was arguably the world's first true computer. The hardware that Perot's team diligently unearthed and lovingly refurbished is now accessible to the general public for the first time, back at the same Army base where it almost rotted into oblivion.

Samsung Shows 'Eye Mouse' For People With Disabilities 17

Posted by Soulskill
from the eye-for-a-ui dept.
Samsung today announced a project among a group of its engineers to build an input device that allows people with limited mobility to operate a computer through eye movement alone. The EYECAN+ is a rectangular box that needs to be situated roughly 60-70cm away from a user's face. Once calibrated, it will superimpose a multifunction UI and track a user's eye movements to move the cursor where they want. Samsung says they won't be commercializing this device, but they'll soon be making the design open source for any company or organization who wants to start building them.

How Intel and Micron May Finally Kill the Hard Disk Drive 421

Posted by Soulskill
from the it-was-the-SSD-in-the-enclosure-with-the-massive-IOPS dept.
itwbennett writes: For too long, it looked like SSD capacity would always lag well behind hard disk drives, which were pushing into the 6TB and 8TB territory while SSDs were primarily 256GB to 512GB. That seems to be ending. In September, Samsung announced a 3.2TB SSD drive. And during an investor webcast last week, Intel announced it will begin offering 3D NAND drives in the second half of next year as part of its joint flash venture with Micron. Meanwhile, hard drive technology has hit the wall in many ways. They can't really spin the drives faster than 7,200 RPM without increasing heat and the rate of failure. All hard drives have now is the capacity argument; speed is all gone. Oh, and price. We'll have to wait and see on that.

A 72-page document throws detailed light on the far-reaching implications of the Pentagon's plan to monopolize imminent "transformational advances" in biotechnology, robotics and artificial intelligence, information technology, nanotechnology, and energy.

jones_supa writes: Eizo has introduced an interesting new PC monitor with a square aspect ratio: the Eizo FlexScan EV2730Q is a 26.5-inch screen with 1:1 aspect ratio and an IPS panel with resolution of 1920 x 1920 pixels. "The extended vertical space is convenient for displaying large amounts of information in long windows, reducing the need for excess scrolling and providing a more efficient view of data," the firm writes. The monitor also offers flicker-free (non-PWM) backlight and reduced blue light features to avoid scorching users' eyes. Would a square display be of any benefit to you?

Linux On a Motorola 68000 Solder-less Breadboard 147

Posted by Soulskill
from the back-to-basics dept.
New submitter lars_stefan_axelsson writes: When I was an undergrad in the eighties, "building" a computer meant that you got a bunch of chips and a soldering iron and went to work. The art is still alive today, but instead of a running BASIC interpreter as the ultimate proof of success, today the crowning achievement is getting Linux to run: "What does it take to build a little 68000-based protoboard computer, and get it running Linux? In my case, about three weeks of spare time, plenty of coffee, and a strong dose of stubbornness. After banging my head against the wall with problems ranging from the inductance of pushbutton switches to memory leaks in the C standard library, it finally works! (video)"

An anonymous reader writes: When looking for a new (or used) car, I have readily available information regarding features, maintenance history, and potential issues for that specific model or generation. What I would really like is a car that is readily hackable on the convenience-feature level. For example, if I want to install a remote starter, or hack the power windows so holding 'up' automatically rolls it up, or install a readout on the rear of the car showing engine RPMs, what make/model/year is the best pick? Have any of you done something similar with your vehicle? Have you found certain models to be ideal or terrible for feature hacking?

The bogosity meter just pegged.
