First solar-powered boat to circle the world pulls into home port, contemplates next move

Sarah Silbert — Fri, 04 May 2012 20:54:00 EST

It's been two years since we last heard of the 98-foot-long solar-powered boat, which at the time was gearing up for its big journey around the world. Well, some 19 months and 37,286 miles after setting sail from Monaco, the MS Turanor PlanetSolar has finally made it home. The PlanetSolar broke four Guinness world records along the way, including the all-important "first circumnavigation by solar-powered boat," and it made stops on six continents to promote solar energy. Oh, and the team fended off Somalian pirates in the process, too. Now that it has a moment to catch its breath and soak up some rays at leisure, the MS Turanor could become any number of things -- from the world's largest solar battery to a "green luxury yacht." The latter option would certainly befit its chichi home port.

Honda test house features Smart Home System for controlling energy usage

Sarah Silbert — Tue, 01 May 2012 19:01:00 EST

The term "smart home" seems to turn up in tech circles every so often, only to fade into the background again without much sign of ultra-connected dwellings becoming a reality. Honda's at least putting one foot forward, with a just-unveiled test house in Saitama, Japan featuring a system for controlling and monitoring energy usage. The Honda Smart Home System (HSHS) consists of thin-film solar cell panels, a rechargeable home battery unit, gas and hot water supply systems and the Smart e Mix Manager. The latter is the central part of the energy-control system, and it keeps track of all the other components in addition to monitoring the home's use of power supplied by the grid. In emergency situations, it can also provide electricity via the home battery unit. On the day-to-day level, however, the system is there to let home owners know what sources of power they can kill. Honda also integrates its Japan-only Internavi system for controlling home appliances remotely. The car maker hopes to use the house for extensive demo testing, with an ultimate goal of reducing CO2 emissions by 50 percent. No word on how many decades till we actually call this sort of place home, though. Click on past the break for a look (in Japanese) at the test home's features.

Study says wind turbines raise surrounding area temperature, but only at night

Sarah Silbert — Mon, 30 Apr 2012 14:47:00 EST

Who said the butterfly effect couldn't apply to renewable energy? Though wind farms are considered pretty green on the energy-generating spectrum, it looks like they, too, have an impact on the planet. According to a study published today in the journal Nature Climate Change, turbines can raise the local temperature -- albeit slightly. From 2003 to 2011, researchers monitored satellite data for west-central Texas, which is home to 2,350-plus turbines and four of the world's largest wind farms. In that decade, scientists observed a temperature increase of 0.72 degrees in wind farm regions compared to areas without turbines. That warming trend was especially marked at night, when the temperature difference between the ground and the air is highest. The temperature increase was also higher in winter; researchers say that these cooler, windier conditions cause turbines to generate more electricity and therefore create more heat. Since the study didn't find any change in daytime temperatures, it looks like we don't have to ring the global warming alarm just yet.

USC develops printable liquid solar cells for flexible, low-cost panels

Sarah Silbert — Fri, 27 Apr 2012 13:21:00 EST

Solar cells are becoming more viable sources of energy -- and as they become more efficient, they're only getting smaller and cheaper to produce. Liquid nanocrystal cells are traditionally inefficient at converting sunlight into electricity, but by adding a synthetic ligand to help transmit currents, researchers at USC have improved their effectiveness. The advantage of these liquid solar cells? They're cheaper than single-crystal silicon wafer solutions, and they're also a shockingly minuscule four nanometers in size, meaning more than 250 billion could fit on the head of a pin. Moreover, they can be printed onto surfaces -- even plastic -- without melting. Ultimately, the goal of this research is to pave the way for ultra-flexible solar panels. However, the scientists are still experimenting with materials for constructing the nanocrystals, since the semiconductor cadmium selenide they've used thus far is too toxic for commercial use.

Facebook flips the switch on its North Carolina data center, cooled with balmy mountain air

Billy Steele — Sat, 21 Apr 2012 03:05:00 EST

Since breaking ground in Western North Carolina some 16 months ago, Facebook has been running at full speed to get its newest data center online. This week, Zuckerberg & Co. flipped the switch. The new facility, located in Forest City, touts the "first major deployment" of the outfit's Open Compute Project web servers and will be the first "live test" of the OPC's outdoor air-cooling design. It tends to get pretty warm around those parts and humidity levels are a bit outside of ideal data center conditions. The Carolina facility will mirror the projected power utilization effectiveness (PUE) of FB's Oregon data center at just a smidge above 1 - somewhere between 1.06 and 1.08 to be exact. In other words, this means the ratio of power used by the structure and the actual power sent to the hardware is almost perfect with minimal energy loss. No matter, it'll still be using plenty of power. A second identical building is slated to open on the site later this year, but for now, hit the source link for a bit more info on the initial launch.

Nest Thermostat update adds 10-day history, helps send chilly air through the home

Dana Wollman — Thu, 05 Apr 2012 09:00:00 EST

There's a first for everything, including Engadget stories about software updates for thermostats. If we're going to suddenly start getting granular in our coverage of home automation products, though, we may as well start with the Nest, a device slick enough to make us use "thermostat" and "sexy' in the same sentence. Now that it's been out on the market for about five months, the company's issuing a software update that introduces a couple new features.

For starters, particularly fastidious users can now access a detailed 10-day history, showing precisely when and for how long their heating and cooling systems kicked in, as well as the reason for that shift (e.g., you manually changed the temperature, were away). Though you can't view all that data on the device's small, circular screen, you can look it up online or through Nest's iOS and Android apps. Next up is Airwave, a feature that uses your fan to distribute chilled air through the home after your air conditioner has turned off (you know, instead of letting one room get intensely, unnecessarily cold). According to Nest, that feature turns on automatically when the temperature is high and the humidity low, though we're hazy on the algorithm being used there. Rounding out the list, Nest has made certain settings easier to access, and the hardware itself will ship with redesigned connectors that purport to work well even without wall anchors. Save for that last bit, current owners can enjoy all these tweaks via a free software update -- fully automated, 'o course.

Inhabitat's Week in Green: supersonic biplane, urban algae farm and magnetic tattoos

Inhabitat — Sun, 25 Mar 2012 20:26:00 EST

Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.

Energy-efficient transportation soared to new heights this week as MIT unveiled designs for a supersonic biplane that promises to be the successor to the Concorde. Meanwhile Boeing, Airbus and Embraer partnered to develop a new breed of affordable biofuels, and Volkswagen used space foil to make cars safer. In hot car news, Porsche announced plans to release a plug-in hybrid Panamera in 2014, and we brought you sneak peeks of several sexy electric vehicles that will be unveiled at the New York Auto Show in just over a week: Fisker's Nina plug-in hybrid and Infiniti's new Nissan leaf-based EV.

On the subject of energy efficiency, it was a big week for clean tech as Inhabitat reported that the world's most powerful wind turbine was just installed off the Belgian coast, and the National Ignition Facility flipped the switch on the world's first two-megajoule ultraviolet laser in an attempt to unlock nuclear fusion. Meanwhile, scientists discovered a link between trees and electricity by studying the way they affecty the concentration of positive and negative ions in the air, and OriginOil announced plans for an urban algae farm near Paris that will heat buildings while treating wastewater. The solar industry heard good news this week as a report showed that solar installations in the US more than doubled in 2011, and President Obama toured the states touting his "all of the above" approach to energy.

This week Inhabitat also showcased several amazing public infrastructure projects - including a series of gigantic fruit-shaped bus shelters in Japan, gmp Architekten's gorgeous new Hangzhou South Railway Station, the fresh new designs for section 3 of NYC's High Line elevated park, and a soaring 30-storey-tall wood skyscraper in Vancouver.

In robot news, a Virginia Tech team created a self-charging robo-Jellyfish that harvests hydrogen fuel from water, and we shared 6 incredible inventions made possible by nanotechnology. F.A.T. Labs released a Free Universal Construction Kit that can connect LEGOs to 8 other types of building blocks, and Amazon purchased a robot company to improve working conditions in its warehouses. As most of you probably know, This American Life issued a retraction of its Apple factory exposé - and while Mike Daisey may lost his credibility, we believe strongly that distrust in the integrity of his "reporting", should not be a reason for consumers to turn a blind eye to working conditions at Foxconn and other electronics ODMs. This week Nokia filed a patent for magnetic tattoos that could vibrate when someone calls, and we learned that free smartphone applications could consume 75% more energy than paid versions. Speaking of mobile phones, new research linked cellphone radiation during pregnancy to behavioral disorders in offspring so we looked at ways pregnant mothers can protect their babies from potential cellphone radiation exposure. Last but not least, we brought you an interesting high-tech clothing concept from Stella McCartney - a sports bra with a built-in heart sensor.

Inhabitat's Week in Green: LA Auto Show, tidal energy farm and Japan's futuristic eco-city

Inhabitat — Sun, 20 Nov 2011 20:30:00 EST

Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.

It was a big week for green cars, as Inhabitat scoured the floors of the LA Auto Show to search for the latest and greatest in green auto design and innovation. We were excited to check out Audi's hybrid-diesel E-Tron Spyder concept car, Croatia's first electric vehicle prototype the DOK-ING XD, and Honda's hotly anticipated 2013 electric version of their popular Fit. Honda also made waves at the west coast auto show with their Civic Natural Gas car, which took home the title of 'Green Car of the Year' -- the Civic is the cleanest running internal combustion car certified by the EPS. Meanwhile, Ford announced that their EVOS plug-in hybrid will be hitting the market next year, FlyKly's ultra-modern electric bikes have become a choice ride in New York City, a German museum decided to recreate an operable version the world's oldest electric car, and the US Navy successfully sent a test-ship out on a 117 hour voyage using a 50 percent algae-derived fuel.

There were also some exciting announcements in clean energy technology this week, including a recent report completed by leading scientists that predict giant orbiting solar power plants could supply all the earth's energy needs by 2041. We also learned that France will open the world's largest tidal energy farm in 2012, and GE will provide the turbines for a $100 million wind farm in Mongolia. Also for Mongolia, a local geo-engineering firm is making plans to battle the capital's scorching hot summers by cooling it down with gigantic manmade chunks of ice that mimic naleds. London's audacious mayor came up with an equally ambitious idea -- his plan is to curb pollution by spraying the city's roads with a sticky calcium-based adhesive able to catch airborne pollutants. We also got the inside scoop from Panasonic's Energy Solution Business Director, Haruyuki Ishio, on the futuristic eco-city that is being planned for Fujisawa, Japan.

Engadget Primed: SSDs and you

Jesse Hicks — Mon, 31 Oct 2011 16:46:00 EST

Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com.

If you're a storage aficionado -- and who here isn't? -- you've probably heard a lot about SSDs, those friendly solid-state disks promising dramatically improved performance over their magnetically inclined brethren. No doubt you've heard about the advantages, thanks to NAND storage that makes them silent, shock resistant, energy efficient and lightning quick. Yet you've also heard the horror stories: drive slowdowns, controller failures and manufacturer recalls. And adding to all those anxiety-producing headlines, there's the price premium. While most magnetic drives average around a nickel or dime per gigabyte, even consumer-grade SSDs still run $1-2 per gigabyte, often for drastically smaller-capacity drives.

Three years ago, Intel launched its X25-M and X18-M: the "M" stood for "mainstream," and the pair of drives were designed to reintroduce solid-state storage to a cost-conscious consumer market. (Perhaps more importantly, they were also meant to solidify Intel's standing in the nascent SSD realm, up to that point a chaotic, Wild West-style domain. But we'll get to that.) For most users magnetic drives still remain king, with solid states appealing primarily to a niche of enterprise IT professionals and modding enthusiasts. How did that happen -- and should it be different? After the break we'll look at how and why SSDs haven't (yet) conquered the storage world, and examine whether they're poised to do just that.

China debuts homegrown supercomputer, hits one petaflop mark

Terrence O'Brien — Mon, 31 Oct 2011 12:41:00 EST

China has already, however briefly, sat atop the Top500 list of supercomputers, but that was using silicon designed by American companies like Intel and NVIDIA. The country's latest contestant though, is sure to be a much bigger point of national pride. The Sunway BlueLight MPP, which was installed at the National Supercomputer Center in Jinan this September, is powered by 8,700 ShenWei SW1600 CPUs -- the homegrown chips that come out of Shanghai. The Sunway's one petaflop performance isn't enough to make it the new king of the hill, but it should get it into the top 20. More impressively, the machine only consumes about one megawatt of electricity -- roughly a quarter of the 2.5 petaflop Tianhe-1A. Now it's up to researchers to crank these ShenWei cores up to a 11 and make a run at that 50 petaflop Cray.

LSI acquires SandForce for $370 million, looks to step up its SSD game

Amar Toor — Thu, 27 Oct 2011 02:45:00 EST

SandForce has been behind many an SSD in its day, but it looks like it's finally about to settle down, and get hitched. Yesterday, LSI announced plans to acquire the flash storage company, as part of a $370 million agreement. The deal brings SandForce's processors and energy efficient DuraClass technology under LSI's roof, giving the semiconductor designer some new flash firepower and an extra boost into a burgeoning market. Tangible results, of course, remain to be seen, though it's certainly not the first time these two have danced. SandForce, after all, provided the motor for LSI's WarpDrive lineup, and will presumably do much more, once the deal goes through. Pending regulatory approval, the acquisition should be finalized by the first quarter of 2012. Full PR after the break.

Sharp's energy-efficient LED ceiling lights are hip to be square

Joseph Volpe — Thu, 11 Aug 2011 05:36:00 EST

If you live in Japan and are looking to lower your household electricity bill, you might have to empty your bank account first. Sharp recently introduced its new line of ELM-branded LED ceiling lights and the highly energy-efficient, square-shaped bulbs won't come cheap -- retailing between 35,000 yen (about $456) and 55,000 yen (about $717). Pulling inspiration from the LEDs used in LCD televisions, the company was able to achieve an industry-leading 81.3 lumens per watt for the smallest of its three designs, and an average life of 40,000 hours for the entire lot . The energy-sipping set of overhead bulbs come housed in an insectproof shell, offering over 100-plus ambient light settings, controllable via remote. You can snag these utility-friendly lights on August 27th, just don't complain at the checkout when you see the price -- we warned you. Peep the video explanation after the break.

Report: data centers accounted for just 1 to 1.5 percent of electricity use last year, Google claims less than 1 percent of that

Dana Wollman — Tue, 02 Aug 2011 16:06:00 EST

You'd think, watching companies like Apple break ground on sprawling data centers, that the number of servers powering our untethered lives was on the rise. In a different decade, you might have been right. But not this one. According to a study prepared at the request of The New York Times, the number of servers in use has declined "significantly" since 2005. That's mostly because of the financial crisis of 2008, says lead researcher Jonathan G. Koomey of Stanford University, but we also can't discount the effect of more efficient technologies. What's more, he says, servers worldwide consume less energy than you might have guessed: they accounted for somewhere between 1 and 1.5 percent of global electricity use in 2010. And while Google, the king of cloud computing, has been cagey about revealing just how many servers house its treasure trove of data, the company said that of that 1 to 1.5 percent, it accounted for less than 1 percent -- meaning, just a hundredth of a percent of all the electricity consumed last year. All told, data centers' energy consumption has risen 56 percent since 2005 -- a far cry from the EPAs 2007 prediction that this figure would double by 2010, with annual costs ballooning to $7.4 billion. Then again, this slower-than-expected growth could well be temporary. Though Koomey can't specify to what extent the financial crisis and technological advancements are to blame, he insists, broadly speaking, that we're primarily seeing fallout from the economic slowdown -- a stay of execution, of sorts, for those of us rooting for energy conservation.

Philips EnduraLED A21 bulb offers bright light for big bucks

Christopher Trout — Mon, 16 May 2011 22:39:00 EST

If the expected price tag for Philips' latest LED light bulb is any indication, a brighter tomorrow won't come cheap. The "75W replacement," known as the EnudraLED A21, apparently reduces energy by 80 percent, lasts 25 times longer than its conventional counterpart, and is expected to cost between $40 and $45. Given that's significantly less expensive than the outfit's 60W equivalent, but for us regular folks, that's not exactly a drop in the bucket. However, if you're picking up what Philips is laying down, the bulb -- which uses a mere 17 watts of electricity to beam 1,100 lumens -- could save the US 5,220 megawatts of electricity and $630,000,000 annually (if we all switch over tomorrow). That certainly sounds good, but somehow we doubt a $45 light bulb is going to be the incandescent killer. Full PR after the break.

EnOcean's home automation sensors communicate over TCP/IP, play nice with smartphone apps

Dana Wollman — Mon, 02 May 2011 14:39:00 EST

EnOcean has long been on our radar thanks to its inexpensive light switches and thermostats, which harvest energy from solar cells and thermal differentials and boast peel-and-stick backs for easy installation. Now, they're getting hooked up for TCP/IP communication, which means in addition to talking to each other, homeowners will be able to control them using any garden-variety web-connected device. The setup will require a small gateway, at which point you can monitor rooms using desktop widgets and mobile apps such as Can2Go that are compatible with EnOcean's radio protocol (ERP). So far, the company's mostly made headway in retail stores and office buildings, but if it has its way, it could be coming to hospitals, college dorms, and (duh) your home.

IE9 is the most energy-efficient modern browser, according to Microsoft's own testing

Vlad Savov — Tue, 29 Mar 2011 19:38:00 EST

Of all the battlefields we've witnessed in the browser wars, this one's never really crossed our minds before: energy efficiency. Yes, the power efficiency of a piece of software, not hardware, is being touted by Microsoft as a differentiating feature for its fresh new Internet Explorer 9. It's thrown together the top five most popular browsers and put them through a cycle of benchmarks -- including Microsoft's own FishIE Tank graphics acceleration test, but not the somewhat popular Adobe Flash -- while measuring how much power they use beyond what the underlying Windows 7 system needs to keep itself going. Shockingly, IE9 was the winner each and every time and there's a tenuous conclusion drawn that if you want good battery life, you'll be going with Internet Explorer. Oh well, whether you consider them a good laugh or really valuable buyer's advice, there's plenty more of these power consumption comparisons at the source link below.

VIA says Eden X2 is world's most power-efficient dual-core processor

Christopher Trout — Fri, 04 Mar 2011 02:25:00 EST

Following close behind the low-power Nano X2 comes the Eden X2, or what VIA is calling "the world's most power-efficient" fanless dual-core processor. While we've yet to see any official numbers, the original Eden did 500MHz on one watt of power, so we should see similarly thrifty specs here. Aside from that, the unit houses two 64-bit cores in a 21 x 21 millimeter package, is compatible with Windows CE and Linux operating systems, and was built using a 40-nanometer manufacturing process. The Eden X2 made its debut at the World Embedded conference this week, and should make it to the real world by the end of Q2. Full PR after the break.

AMD has a 5W Fusion APU to put in your future tablet of choice

Vlad Savov — Mon, 31 Jan 2011 06:26:00 EST

The same Singapore event that brought us our first look at AMD's humongous Radeon HD 6990 has also served as the stage for the company's first showing of a new, even lower-powered Fusion APU. The regular dual-core Ontario (C-50) variant requires a 9W power budget to operate, but AMD's managed to shrink that down to 5W in a chip designed specifically to be used in tablets. Clock speed remains at 1GHz and the core count hasn't bee touched, but the memory controller has been dumbed down and peripheral ports have been reduced to one of each type. This streamlined C-50 has already found a home in Acer's 10.1-inch Windows 7 tablet and should prove decently popular among manufacturers looking for an x86 alternative to the coming tidal wave of ARM-based devices.

MIT developing smart adaptive LED lighting system to reduce energy use by up to 90 percent

Richard Lai — Sun, 28 Nov 2010 23:01:00 EST

It's very well that manufacturers are constantly pushing for more efficient LEDs, but we can do better than that: what if we could have an LED lighting system that pumps out just the right amount of juice to suit our changing environment? That's exactly what the tree huggers at MIT are working on right now. Said adaptive system relies on a small box that not only acts as a position tracker, calibrator and sensor for the dimmable overhead LED fixtures, but also lets the user set the desired tone and light intensity for the room. In other words: no matter how sunny or cloudy it is outside, you'll still be comfortably basking in the same steady shine in your room, while also saving up to 90 percent of energy. Our guess is that Philips -- the project's sponsor -- will eventually release a product based on this technology, but for now, you can see the system in action after the break (from 1:07).

Nexus One sees red, nearly doubles battery life? (video)

Sean Hollister — Sat, 03 Jul 2010 20:08:00 EST

These five Nexus One smartphones may seem to have defects, but there's actually nothing wrong with their AMOLED screens -- the funky colors are an attempt to improve battery life by turning off unnecessary sub-pixel LEDs. Hooking up his handset to an industrial power meter, Android engineer Jeff Sharkey discovered a blood-red screen drew 42 percent less current than full color -- the least of any combination by far -- purportedly doubling the effective battery life of the phone. While you're probably not going to be able to test the requisite software patch for yourself unless you're mildly familiar with Google code, you'll find a video of the crimson wonder after the break to fuel your dreams of a eyestrain-free astronomy cheat sheet... and Android bullfighting, of course.

VIA Nano E-Series CPUs offer native 64-bit support, guaranteed longevity, and extreme energy efficiency

Vlad Savov — Fri, 23 Apr 2010 07:49:00 EST

Oh, look who it is. The company that was supposed to give the Atom a good run for its money is back at it today with the announcement of a new E-Series of processors, operating at speeds between 800MHz and 1.8GHz. Bringing native 64-bit software and virtualization support, as well as a 7-year guarantee, these will certainly appeal to business types, while their minimal idle power consumption (as low as 100mW) and multimedia-accelerating promises should garner some interest from consumers as well. VIA is promising "exceptional hardware acceleration of the most demanding HD video codecs and industry leading 3D graphics capabilities" when these CPUs get dropped into integrated chipsets like the VN1000. Them's fighting words indeed, and we should be able to gauge their veracity in due course with samples available for interested parties right now and mass production sure to swiftly follow. Go past the break for the full PR.

LED traffic lights don't melt snow, do cause accidents

Vlad Savov — Thu, 17 Dec 2009 09:16:00 EST

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.

Inside Sharp's new LCD factory, we can see our next HDTV from here

Richard Lawler — Mon, 30 Nov 2009 21:46:00 EST

The path back to LCD leadership for Sharp begins at its just opened Sakai City manufacturing facility. Being a 10th generation facility means it can roll out more and bigger displays, producing six 60-inch LCDs from each glass substrate, 60% more than older 8g facilities. Check out the pics for a peek at where 72,000 substrates per month will be made, delivering those slim LED backlit televisions getting so much love, along with solar panels (also being installed on the roofs for that extra green vibe that's in vogue these days) and a few of the more than 100,000 energy efficient LEDs lighting the factory itself. Whether your closest HDTV purchase is a turkey fueled memory from last weekend or yet to come, bargain hunters and AV fans alike can appreciate an eyeful of the robots and testing equipment slicing, dicing and stamping screens headed for shelves nearby, whether bearing an Aquos brand or any number of other nameplates.

3M optical film for greener LCDs making an appearance at FPD International 2009

Richard Lawler — Tue, 20 Oct 2009 10:38:00 EST

Not happy with the green TV movement so far? 3M promises its latest Vikuiti Optical Film technology will save 32% more energy in LCD screens under 40-inches, without cutting into image quality, while enhancing the viewing angle and color uniformity. Checking it out before this film makes its way into the latest LCDs will require a trip to the FPD International show next week in Japan, where the it will also show off film intended for autostereoscopic (no glasses) 3D handhelds, but just a note, tearing off a piece and sticking it on your VIZIO at home won't help, we've tried that.

AMD 's new Athlon II processors aim to go easy on the power, your wallet

Vlad Savov — Tue, 20 Oct 2009 04:12:00 EST

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

Vlad Savov — Mon, 19 Oct 2009 07:18:00 EST

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.

OSU foresters swap tree fibers for rubber in fuel efficient tires

Darren Murph — Sun, 26 Jul 2009 12:41:00 EST

Leave it to a gaggle of brilliant wood science researchers at Oregon State University to figure out that we've been doing this whole "tire" thing wrong for generations now. While studying some uses of microcrystalline cellulose, which can be made easily from practically any type of plant fiber, these Earth-loving gurus discovered that said material could actually improve the efficiency of vehicle tires when used in place of silica. Granted, only about 12 percent of the silica -- which is used as a reinforcing filler in the manufacture of rubber tires -- was swapped out, but the resulting tires gripped just as well in wet weather while decreasing the rolling resistance during those dry summer months. Furthermore, tires constructed with these fibers could be made with less energy, though long-term durability studies are still needed to prove that this whole plan is viable for more than a few thousand miles.

Integrated circuits with no standby power could be in use by year's end

Donald Melanson — Sun, 19 Jul 2009 20:56:00 EST

There's certainly no shortage of companies working to make electronics of all sorts more energy efficient, but NEC and Rohm Co now say that they're on the verge of a breakthrough that could change things in a big way, and we could possibly see it in "practical use" by the end of this year. As Tech-On! reports, both companies are hard at work on integrated circuits that consume no power at all when they're in standby mode, and turn themselves on only when power is needed. That's apparently possible by making the entire chip nonvolatile, as opposed to many current chips that only use nonvolatile merged memory. According to NEC, that'll let them "cut dissipation for digital consumer electronics in the standby mode to just a few percent of what it is now," and at no expense of convenience. While NEC isn't making any promises for the near future just yet, Rohm says that it'll begin shipping its first custom ICs in the second half of this year, and that the first products using them could start showing up by the end of 2009.

InterHome learns from inhabitants, adapts to save energy

Darren Murph — Mon, 06 Jul 2009 07:59:00 EST

We've seen all sorts of devices that learn over time, though most of them fall into the humanoid category. Now, a team of gurus over in the UK has developed an entire home that can learn from those dwelling in it and react in order to curb energy waste and even prevent unauthorized entry. InterHome, a model designed by researchers at the University of Hertfordshire, is scheduled to be unveiled at the Microsoft Imagine Cup finals, and it should make other home automation systems look rather antediluvian in comparison. By sensing how the owner(s) like their climate and such, it can reportedly save up to £300 a year in energy costs alone. Furthermore, it can "take decisive action and text if it is being burgled or the door has been left unlocked," and the whole system can be monitored remotely and controlled via the web. Too bad we're terrified that it could one day turn on the owner and refuse to allow entry to anyone other than leaders of The Resistance, but other than that, it sounds pretty nifty.

Seagate rolls out low-power Barracuda LP hard drives

Donald Melanson — Wed, 22 Apr 2009 13:57:00 EST

Seagate's Barracuda drives have been plagued with a few problems as of late, but it looks like the company is doing its best to push the line in a fresh new direction with its just-announced Barracuda LP series, which promise to cut down on power consumption without making too many compromises in performance. Specifically, Seagate says that the drives will use up to 50% less electricity than standard hard drives, while also cranking out 5,900 RPM, along with an average latency of 5.5ms, and a 32MB cache. No word on what so of premium, if any, they'll demand, but you'll apparently be able to get 'em in 1TB, 1.5TB, and 2TB varieties (all 3.5-inch) right out of the gate.

LG FreeSat LCDs are finally official, shipping this month

Richard Lawler — Thu, 09 Apr 2009 18:05:00 EST

LG is ready to ship its line of LCDs with integrated FreeSat tuners starting this month. The 1080p LF7700 series comes in sizes from 32- to 47-inches and includes 100Hz Trumotion in the 42- and 47-inch versions, with a 50,000:1 dynamic contrast ratio and invisible speaker design. Don't think a TV would hit the market today without the green tag, these claim to use 69% less power, thanks to the integrated light sensor. The cheap ones start at £700, even with BBC HD and ITV HD beckoning lackluster UK buyers may choose to wait for the 200Hz LH5000 models due later this year.

Hitachi unveils 11 latest Wooo plasmas and LCDs: Greener, better looking & network connected

Richard Lawler — Thu, 09 Apr 2009 08:41:00 EST

This year's edition of the Hitachi Wooo line of flat panels look a lot like their predecessors on the outside (120Hz IPS LCDs, 250GB HDD equipped models with iVDR slots for additional hard drives and Wooonet DLNA network support) but it's what's inside that counts. The four new XP plasma models range from 42- to 50-inches and promise even better contrast ratios, as high as 40,000:1, with better color reproduction and the promise of greater energy efficiency. The ultra-thin 35mm / 1.4-inch thick LCDs are back in four new models, with UWB wirelessly connected tuners, auto sensing/adjusting brightness and aforementioned "eco" power sipping improvements. The relatively fat XP line of LCDs consists of just three displays, but just like all the rest, buyers can still hook up to the 'net and pull down video on-demand or Yahoo! Japan's web TV portal -- features unlikely to make the jump when we see U.S. versions of these later this year. The XP plasmas and LCDs go on sale in Japan later this month or next, while the ultra-thins will be crash dieting until October.

Google's Data Center secrets revealed!

Joseph L. Flatley — Thu, 02 Apr 2009 14:08:00 EST

After years of secrecy (maybe because they thought no one was interested), Google held its "Data Center Efficiency Summit" yesterday, where the company showed off one of its DCs and custom web servers -- all in a bid to evangelize for energy efficiency. The green angle means that everything has been planned for optimum power use, from the 1AAA shipping containers (sporting over a thousand servers each) that make up the core of its operations, to the servers themselves -- each containing its own 12-volt UPS. This design is said to boast a staggering 99.9 percent energy efficiency, as opposed to a standard centralized UPS setup which at best would only score 95 percent. According to CNET, these are efficiency levels that the EPA doesn't envision as practical until at least 2011. But that ain't all -- hit that read link for the whole sordid affair, but not before you check out the video of a server itself after the break.

Intel Core 2 Quad S-Series shaves power consumption to 65W

Darren Murph — Sun, 29 Mar 2009 10:44:00 EST

In a relatively hush-hush manner, Intel recently slipped out energy saving versions of its Core 2 Quad Q8200, Q9400 and Q9550 CPUs, all of which are suffixed with a simple "s." Put simply, these S-Series chips are built using the same 45 nanometer process technology as used on the regular models, and aside from TDP, all the specifications are exactly alike. The difference comes in power consumption, as the S crew sucks down just 65 watts compared to 95 watts in the standard issue models. Tom's Hardware had a chance to handle, benchmark and report on these new power sippers, and lucky for you, they found performance to be equal to that of the higher power chips. Granted, you'll have to pony up a few extra bucks in order to treat Mother Earth (and your energy bill) better, but at least we're working down the power ladder instead of the other way around.

Probabilistic logic makes microchip more energy efficient

Darren Murph — Mon, 09 Feb 2009 06:09:00 EST

We'll be straight up with you -- there's a lot of fancy work going on with this one that laypeople will have a tough time grasping, but the long and short of it is this: a team from Rice University (Krishna Palem pictured) and Nanyang Technological University have created a microchip that "uses 30 times less electricity while running seven times faster than today's best technology." Already crying snake oil? Not so fast. By trashing the traditional set of mathematical rules (that'd be Boolean logic) and instead applying probabilistic logic, researchers have figured out how to deliver similar results with a fraction of the energy. The tech is being dubbed PCMOS (probabilistic CMOS), and could eventually end up in embedded systems and even cellphones. In the case of the latter, this type of chip will be able to display streaming video on a minuscule display with more artifacts than usual, but due to the small screen size and the human brain's ability to piece together nearly-perfect images, the errors involved would be all but forgotten. Meanwhile, your battery bar would still be nearly full. We always heard there was beauty in imperfections -- now, at long last, we finally get it.
