Qualcomm's Peanut challenges ZigBee, Bluetooth for control of your personal area network next year
Perhaps dissatisfied with the glacial pace of Wibree, Qualcomm's working on an ultra-low-power, short-range wireless transfer tech of its own -- it's called Peanut, and executives claim it only needs "fractions of a milliwatt of power" to push data at several megabits per second. Computerworld got the scoop on the new low-power radio at EmTech@MIT 2010, and reports that Qualcomm's had these goobers in the oven since 2006 and is looking to trump the likes of ZigBee and Bluetooth by this time next year. Assuming, of course, the Peanut standard doesn't require a molasses-like committee of its own to attain formal approval.
Cambridge scientists develop lower-than-low power WORM memory
Researchers at Cambridge University have recently published a paper on their new type of WORM (write once read many) memory which is even more low powered than the ones that came before it. The new electron-only design of the memory is solution processed, making it low cost as well as it requires no lithography. The device, using ZnO semiconductor nanoparticles to inject electrons into a polymer which is capable of conducting. The electrons are then used to program the memory by permanently lowering the conductivity of the polymer, producing insulation. This result is far lower power densities than previously recorded, by orders of magnitude. The research team believes that it can make further improvements to the device as they continue to work.
ViewSonic outs energy efficient, earth-friendly VOT125 nettop -- won't help that there oil spill
Way back at CES in January, we spied ViewSonic's full offering, and we caught wind then of the VOT125 nettop -- but we didn't really have any details to go on. Well, the company's officially announced the VOT125 PC Mini today, and the slim little guy looks pretty cute. Sold as a space-saving PC with green design, ViewSonic says that the VOT125 uses up to 90 percent less plastic than similar nettops, and consumes up to 90 percent less power, making use of a range of ultra low power Intel ULV CPUs. The VOT125 boasts 2GB of memory, a 250GB hard drive, four USB 2.0 ports, plus DVI / HDMI. You can grab one up starting today, and it's got a starting price of $499. The full PR follows.
Bluetooth 4.0 with low energy (almost) finally ready to roll
Molasses, snails and glaciers: none are slower than an organization developing a new wireless standard. The Bluetooth Special Interest Group (SIG) is no exception -- it's been nearly three years since it announced it would roll Wibree into Bluetooth and four months since it made Bluetooth 4.0 official, but still no dice. This week, the SIG says the low-power specification is ready for action, its minutiae finalized. However, fine print in the org's press release disagrees. The main reason for Bluetooth 4.0 was to include lower power devices, but that all-important integration is still pending a "before June 2010" completion date. That means we still won't see Bluetooth-toting cats till the end of the year, and we have no idea what SIG has accomplished in the meanwhile. Press release after the break.
LED traffic lights don't melt snow, do cause accidents
A number of cold weather American states are reporting their dismay at finding out that LED traffic lights are so energy efficient that they do not produce enough excess heat to dissipate any snow that covers them. It turns out, perhaps in an homage to bad engineering everywhere, that the inefficiency of incandescent light bulbs was previously relied upon to keep traffic signals unimpeded. The new LEDs do not achieve the same effect, which has resulted in a few accidents and even a death being blamed on obstructed traffic lights. Feel free to apply palm to face now. It's not all gloomy, though, as the majority of people are said to treat a dysfunctional traffic light as a stop sign (how clever of them), and a tech fix is being worked on as we speak.
AMD 's new Athlon II processors aim to go easy on the power, your wallet
AMD has just outed a selection of new Athlon II procs, which do little to help it reclaim the performance crown, but will be of interest to anyone who likes to keep things minimal -- whether we're talking about prices or temperatures. Starting at $69 per chip (when bought in bulk) with the 2.7GHz dual-core X2 235e and topping out at $143 for the 2.3GHz quad-core X4 605e, AMD's new e-tagged processors operate within a 45W thermal envelope, as opposed to the relatively standard 65W TDP. The Sunnyvale outfit makes some ill-advised claims of "up to 75 percent" better performance versus comparable Intel CPUs -- the small print tells us that number is derived from 3DMark Vantage while testing with different GPUs -- but we suppose until the Thuban six-core shows up, AMD will have to take performance gains from wherever it can get 'em, including its own imagination.
Texas Instruments CC2540 promises ultra-low energy Bluetooth
Texas Instruments is pretty chuffed with itself right about now, as it's prepping to demonstrate a swell-sounding new system-on-chip that takes Bluetooth connectivity to the extreme reaches of low energy consumption. About to be shown off in Munich tomorrow, the new CC2540 takes up a measly 6mm-squared of real estate, and is said to be able to operate for more than a year on a single button cell battery. With the reduced physical size and embedded Flash memory, this should be easier to install and update as necessary too. Considering the battery-draining ways of current Bluetooth tech, such claims sound preposterously awesome, but we'll keep our giddy enthusiasm in check until early next year when samples will begin rolling out. For now, you can check out the older video below 'splaining the prospective benefits in more detail.

Flexible, stretchable, rubbery OLED prototype shown off in Tokyo
Electrical engineering researchers at the University of Tokyo have developed a flexible, stretchable OLED that acts something like rubber, and does not tear or break when stretched. The material is produced by spraying a layer of carbon nanotubes with a fluoro-rubber compound, creating a rubbery, conducive material. The current, monochrome display prototype has a resolution of just 256 pixels, is 10-centimeters square, and can apparently be folded about 1,000 times with out falling apart, tearing, or imploding. The team is presenting its findings in the British science journal Nature Materials this month.[Via Slashgear]
fit-PC slim, the 'world's smallest PC' -- just don't lose it on your desk
fit-PC Slim is billed as the "smallest, most energy efficient PC available," and at 13 ounces it just might be. Slim is housed in a 330cc enclosure (4.3 x 3.9 x 1.2 inches), draws a mere 6 watts of power, and like the Linutop 2, runs on a 500MHz AMD Geode. This machine is available in a pared-down 256MB configuration (sans WiFi, hard drive) for $220; a 512MB WiFi version (with no hard drive) for $245; or go all out with the 512MB / WiFi / 60GB hard disk version pre-installed with either Ubuntu or Windows XP Home SP3, for $295 or $335, respectively.[Via LinuxDevices]
Texas Instruments gets excited about energy scavenging
Texas Instruments has a lot to do with the original microchip, if for no other reason than being the employer of inventor Jack Kilby. Now, however, TI is looking to produce chips and other related gizmos that require an infinitesimally small amount of energy to operate. The overriding theme guiding the engineers is "energy scavenging," which alludes to grasping power from even the most unlikely of places -- vibrations from a bridge as cars pass over, capturing wasted exhaust from a car or bottling up all that frustration your sibling shows when you own him / her again in Super Smash Bros. Brawl. The possibilities are just about endless, with networked battery-free smoke alarms, solar-powered mobiles and gaming laptops that feed off of extraordinarily focused brain waves in the mix. Okay, so that last one is still eons from reality, but at least we're headed in that direction.
The Linutop 2 gets green on your desktop
If you're after a really, really low power, small footprint, generally inoffensive desktop solution, you probably can't do better than the new Linutop 2. This miniscule, Xubuntu-based system runs on top of a 500MHz AMD Geode CPU, packs in 512MB of RAM, and 1GB of flash memory, you know, for applications and stuff. Of course, the draw here isn't massive specs, but rather a tiny drain on energy, and a simple, cheap solution for people with basic computing needs. Amazingly, the Linutop 2 uses only 8 watts of power, and weighs a feather-light 20 ounces. The miniature box also has four USB ports, an ethernet jack, audio outs, and comes bundled with open source gems like AbiWord, Open Office, and your good buddy, Firefox. The little guy starts shipping on February 26th for €280, or about $412.[Via LinuxDevices]
Apple considered small chip startup over Intel?
Steve Jobs' announcement -- almost a year ago, now -- that Apple was transitioning to x86 processors was one of the most shocking bits of news that the industry had ever heard, and yet there were a group of employees at a startup chip manufacturer called PA Semi who were even more shocked than most, according to reports, because right up until that keynote, they were sure that their company, and not Intel, would be chosen to supply the brains for what's now known as the MacBook family of laptops. The Register is reporting that PA Semi had a close relationship with Apple in the months prior to the switch, and that the two companies were working together to gauge the feasibility of running native PowerPC-coded software on 2GHz dual-core chips that PA Semi claims run at only a third of the 21 to 25 watts consumed by Intel's Core Duo models. Sources who spoke to El Reg say that executives were virtually positive that they'd win the contract, and that CEO Dan Dobberpuhl was understandably "furious" when he found out PA Semi had been passed over. The company still has a bright future developing chips for the embedded market and storage devices, but they'll probably never again have the opportunity to become an instantly-recognized name like Intel, AMD, or IBM.
iPods will gain in battery life with new Wolfson audio chip
Wolfson Microelectronics, the company behind audio chips found in almost every iPod model, is unveiling a low power masterpiece, the WM8985. The new chip will give up to 70 percent more listening time according to Wolfson. This means if your current iPod can play music for 14 hours (a statistic for a typical 5G iPod), with the new Wolfson chip and a similar battery the same iPod would be able to play for 23.8 hours.This type of statistic is rather unrealistic because each iPod upgrade means larger screens and a higher screen brightness and therefore a device that consumes more batteries. A 70 percent increase in battery life for this single chip is, however, quite a leap (most gains in chip power consumption are in the 20 to 30 percent range). It will be interesting to see if the WM8985 chip stays at a price point favorable to Apple with this new release.[via Macworld UK]
