Researchers over at the National Renewable Energy Lab have reportedly made the first solar cell with an external quantum efficiency over 100 percent. Quantum efficiency relates to the number of electrons-per-second flowing in a solar cell circuit, divided by the number of photons from the energy entering. The NREL team recorded an efficiency topping out at 114 percent, by creating the first working multiple exciton generation (MEG) cell. Using MEG, a single high energy photon can produce more than one electron-hole pair per absorbed photon. The extra efficiency comes from quantum dots ‘harvesting’ energy that would otherwise be lost as heat. The cell itself uses anti-reflection coating on a transparent conductor, layered with zinc oxide, lead selenide, and gold. NREL scientist Arthur J. Nozik predicted as far back as 2001 that MEG would do the job, but it’s taken until now for the concept to leap over from theory. The hope is, of course, that this will lead to more competitively priced solar power, fueling the transport of the future.So in the future who owns the most desert wins the power race.. oh wait. isn’t that the middle easterners again. ;D

Gordon Murray, designer of the truly insane McLaren F1, swept the board at the RAC Future Car Challenge this Saturday — but for something much more sensible. It’s the 1,500lbs T.27 EV, the little wonder in the picture above, which just carried two people the 57.13 miles from Brighton to London on just 64p ($1.20) of electricity. Compared to a petrol car that would be the equivalent of getting 350MPG. It’s believed the T.27 can easily make 100 miles on a single four-hour charge and scooped eleven awards on the day, including most efficient and best EV. Murray is still waiting on a manufacturer to sign on to produce the things, but thanks to his super efficient iStream process, they could pop up for sale soon after — which can only be good news for anyone who wants a commuting vehicle with something of a racing pedigree.

Here is the specs :

Thought Windows on ARM was snazzy? Have a gander at this. The outfit’s forthcoming ARMv8 architecture, the first ARM architecture to include a 64-bit instruction set, has just been detailed, with a goal to expand the reach of ARM processor-based solutions “into consumer and enterprise applications where extended virtual addressing and 64-bit data processing are required.” The ARMv8 architecture consists of two main execution states — AArch64 and AArch32 — and we’re apt to see the real benefits hit high-end servers first. The ARMv8 architecture specifications are available now to partners under license, with the company planning to disclose processors based on ARMv8 during 2012, with consumer and enterprise prototype systems expected in 2014. Head on past the break for ARM’s take, or meander to the source links for AppliedMicro’s gloating.

(Reuters) – Samsung Electronics, the world’s No.1 memory chip maker, said it started mass production at a new $10 billion chip line, as it seeks to raise its share in the booming flash memory chip market fueled by robust demand growth in mobile products.

Samsung’s new production line, its first in about five years, will help the company sharply lower production costs of the chips and could exacerbate oversupply in the market, stifling smaller rivals.Apple Inc, the maker of popular iPhones and iPads, and Sony, which joined the crowded tablet market last month with two new devices, buy flash memory chips from Samsung.The cost-competitive facility will make it difficult for its major customers to shift away to other suppliers.Apple, Samsung’s biggest customer locked in a series of patent legal battles with the South Korean firm, is trying to reduce sourcing from the emerging competitor.”The new line won’t have any immediate impact on the supply side, as it will take some nine months to fully raise capacity run rates, but it shows Samsung’s attempt to take more share in the flash chip market,” said Song Myung-sup, an analyst at HI Investment & Securities.Samsung, the world’s biggest technology firm by revenue, on Thursday said the new line was the industry’s largest and most advanced memory fabrication facility, producing chips with 20-nanometre class processing technology.Lower line-widths processing technology allows more circuits on a chip, making them smaller, cheaper, more powerful and more energy efficient.By 0355 GMT, shares in Samsung dropped 3.4 percent, versus a 3.3 percent drop in the broader market.

So, this is pretty… big. At this very moment, researchers at IBM are building the largest data drive ever — a 120 petabyte beast comprised of some 200,000 normal HDDs working in concert. To put that into perspective, 120 petabytes is the equivalent of 120 million gigabytes, (or enough space to hold about 24 billion, average-sized MP3’s), and significantly more spacious than the 15 petabyte capacity found in the biggest arrays currently in use. To achieve this, IBM aligned individual drives in horizontal drawers, as in most data centers, but made these spaces even wider, in order to accommodate more disks within smaller confines. Engineers also implemented a new data backup mechanism, whereby information from dying disks is slowly reproduced on a replacement drive, allowing the system to continue running without any slowdown. A system called GPFS, meanwhile, spreads stored files over multiple disks, allowing the machine to read or write different parts of a given file at once, while indexing its entire collection at breakneck speeds. The company developed this particular system for an unnamed client looking to conduct complex simulations, but Bruce Hillsberg, IBM’s director of storage research, says it may be only a matter of time before all cloud computing systems sport similar architectures. For the moment, however, he admits that his creation is still “on the lunatic fringe.”

Hey there, friends. Do you have the voice-calling blues, wishing for a better way to talk to your friends — without using your minutes? Consider Viber, a free VoIP app that launched for the iPhone last year. Usable over 3G or WiFi, with built-in SMS, it requires no registration, using your existing phone number and contact list. Our only quibble? A disheartening lack of Android support. But our spirits are lifted today, with the app making its way to the everyone’s favorite olive-green market. It has all the compelling features of the iOS version, plus a few extras we saw in the limited beta, like pop-up text message notification, in-app call logs, and the option to use Viber as your default dialer. The company must be doing something right, as it claims 12 million active users just seven months after launch. Interested in being one of them? Check the full PR — with video! — after the break.

You’ve got to hand it to IBM’s engineers. They drag themselves into work after their company’s 100th birthday party, pop a few Alka-Seltzers and then promptly announce yet another seismic invention. This time it’s a new kind of phase change memory (PCM) that reads and writes 100 times faster than flash, stays reliable for millions of write-cycles (as opposed to just thousands with flash), and is cheap enough to be used in anything from enterprise-level servers all the way down to mobile phones. PCM is based on a special alloy that can be nudged into different physical states, or phases, by controlled bursts of electricity. In the past, the technology suffered from the tendency of one of the states to relax and increase its electrical resistance over time, leading to read errors. Another limitation was that each alloy cell could only store a single bit of data. But IBM employees burn through problems like these on their cigarette breaks: not only is their latest variant more reliable, it can also store four data bits per cell, which means we can expect a data storage “paradigm shift” within the next five years. Combine this with Intel’s promised 50Gbps interconnect, which has a similar ETA, and data will start flowing faster than booze from an open bar on the boss’s tab. There’s more detailed science in the PR after the break, if you have a clear head.

Planning to replace that aging Blu-ray player with a Wii U? Not so fast. Nintendo president Satoru Iwata says the gaming console won’t play DVD or Blu-ray discs, due to patent licensing fees.

Wii U does not have DVD or Blu-ray playback capabilities. The reason for that is that we feel that enough people already have devices that are capable of playing DVDs and Blu-ray, such that it didn’t warrant the cost involved to build that functionality into the Wii U console because of the patents related to those technologies.

So there you have it. Iwata doesn’t want to hand over a bag of cash for baby Blu’s “bag of hurt.” By the time the Wii U hits store shelves in 2012, we may be buying Blu-ray players just for their Netflix capabilities, so here’s to hoping the console at least carries over that functionality from its predecessor.

An Apple patent in the US has shown the company exploring the idea of LCDs with switchable privacy levels. A screen on a device like an iPad, iPod, or Mac would have a “scattering module” behind the screen, as well as wedge-like liquid crystal elements in the screen itself, that would steer the lights going through the display. Toggling a privacy mode on the device would narrow the cone of light so that someone couldn’t spy on the screen while still giving the owner a clear view when looking head-on.

Along with its effect on mobile devices, Apple covered as many potential use cases as possible, including the idea of using it for a driver-only display in a car. Apple didn’t limit the technology to LCDs and opened the possibility to OLED, the largely defunct SED, and even carbon nanotube screens. iPods were used as example drawings but are believed to just be placeholders and not indicative of any design plans.

Apple filed for the patent in November 2009 and likely developed it knowing the iPad and other devices were candidates. Patents like this aren’t necessarily indicative of Apple’s actual plans.

Privacy screens are common features on some notebooks today but are used primarily for corporate PCs and rely on basic film covers to achieve the effect. Apple’s strategy, if made real, could lead both to a truly integrated, user-controlled privacy display and expand it to truly mobile devices.
