    You might not think of your air conditioner (AC) as contributing to climate change, but typical AC units use quite a bit of power, which leads to higher greenhouse gas emissions. In a vicious global warming cycle, as the planet gets hotter, more people will turn to air conditioning. So, companies like Airbitat are working on more efficient cooling methods, like the Airbitat Compact Cooler, which just won a CES 2020 Climate Change Innovator Award.

    If you've had a window seat next to the wing of an airplane, you've probably watched as flaps on the wing engage and disengage as a plane takes off and lands. That's because in each phase of flight -- take off, landing, cruising and maneuvering -- the ideal wing parameters vary. Until now, we've made do by modifying rigid wings with hinged surfaces. But imagine if the entire wing could change shape -- that's what researchers led by NASA and MIT are working towards.

    Data backups come in all shapes and sizes. For some, they take the form of external hard drives or a slice of the amorphous cloud. As for Facebook, its upcoming solution is low-power deep-storage hardware contained within a 62,000 square-foot building in Prineville, Oregon near its existing Beaver State data center. Unofficially referred to as "Sub-Zero," the facility will store a copy of the social network's data in case its primary servers need to be restored in an emergency. Rather than continuously power HDDs that are only occasionally used, the new setup can conserve energy by lighting-up drives just when they're needed. One of the company's existing server racks eats up around 4.5 kilowatts, while those at Sub-Zero are each expected to consume approximately 1.5 kilowatts once they're up and running. Tom Furlong, Facebook's vice president of site operations, told Wired that there are hopes to create a similar structure alongside the firm's North Carolina data center. Since the Prineville project is still being planned, Zuckerberg & Co. have roughly six to nine months to suss out all the details before your photos are backed up at the new digs.

    More Facebook news, but this time we're back to the numbers instead of reporting on a new feature, improvement or integration. As part of its mission to swap the familiar blue for something of a greener tinge, Facebook released today its carbon footprint and overall energy usage figures for 2011. Turning bio-babble into easy visualizations, the company points out that for the whole year, an active user occupied roughly the same carbon footprint as one medium latte. Or, if you're a fan of the tipple, a couple of glasses of wine. Impressively, 23 percent of the social giant's energy usage came from clean and renewable sources, which puts it well on the way to its 2015 target of 25 percent or more. If you'd like more info and a complete breakdown of the stats, the full report is available at the source link below.

    We've seen more than a few energy monitors, but how many of them offer a pretty light show on the side? The EnergyBuddy -- first unveiled as a prototype at CES but just now inching toward a full launch -- is a complete home energy-tracking system brought to you by Cali-based startup FutureDash. Starting at $99, it keeps tabs on users' energy consumption with a square-shaped gadget that connects to your network via WiFi or Ethernet. The square glows red, yellow or green depending on how much electricity you're guzzling, and you have the ability to specify what qualifies as acceptable usage. Naturally, the EnergyBuddy has a few peripherals in tow. A sensor installed at your electrical panel communicates with the rest of the system, and so-called Smart Plugs let you track the energy consumption of individual devices. The iPhone, iPad and desktop apps also offer some pretty in-depth stats, including dollars per hour spent on energy and a chart detailing consumption throughout the day. FutureDash is currently pushing the product on crowd-funding site Indiegogo, and though availability is TBD, you can take a peek at the system in our hands-on video below. %Gallery-159188% Joseph Volpe contributed to this report.

    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.

    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

    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.

    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.

    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.

    It's a little strange crowning a "winner" when only a single company enters the contest, but that's exactly what happened during the L Prize celebration in August of last year. Philips was the only outfit to take the US Department of Energy up on its offer, earning some $10 million to develop what might go down as the most radically designed, wildly expensive bulb your table lamp has ever seen. That said, the victorious bulb is a big fan of Ma Earth (and her of him), using just 10 watts of energy while outputting light similar to that of a 60 watt incandescent. It'll hit retailers like Home Depot this Sunday (Earth Day) for around $50 a pop, while some utility companies may subsidize 'em in an effort to hit the magical $20 price point. Hey, no one said saving energy would be remotely affordable, right?

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

    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.

    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

    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

    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.

    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.

    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.
