An anonymous reader writes "Getting access to enough water to drink in a desert environment is a pretty tough proposition, but Eole Water may have solved the problem. It has created a wind turbine that can extract up to 1,000 liters of water per day from the air. All it requires is a 15mph wind to generate the 30kW's of power required for the process to happen. The end result is a tank full of purified water ready to drink at the base of each turbine."

miller60 writes "Apple says Greenpeace has wildly overestimated the amount of power it uses in its data center in North Carolina, and used that bad math to give the company a low grade on sustainability. Apple says it uses 20 megawatts of power at its iDataCenter, a fraction of Greenpeace's estimate of 100 megawatts in a new report on energy use by cloud computing providers. Apple says that its huge solar array and biogas-powered fuel cell will supply 60 percent of the facility's power, not the 10 percent claimed by Greenpeace."
mdsolar writes in with a Reuters article about the continued fallout of Fukushima on the nuclear industry in Japan. "Japan will within weeks have no nuclear power for the first time in more than 40 years, after the trade minister said two reactors idled after the Fukushima disaster would not be back online before the last one currently operating is shut down. Trade Minister Yukio Edano signaled it would take at least several weeks before the government, keen to avoid a power crunch, can give a final go-ahead to restarts, meaning Japan is set on May 6 to mark its first nuclear power-free day since 1970. 'If we thoroughly go through the procedure, it would be (on or) after May 6 even if we could restart them,' Edano told a news conference, adding that whether they can actually be brought back online is still up to ongoing discussions. The crisis at the Fukushima Daiichi nuclear plant, where a huge earthquake and tsunami in March 2011 triggered radiation leaks, has hammered public faith in nuclear power and prevented the restart of reactors shut down for regular maintenance checks, with all but one of 54 reactors now offline."
MrSeb writes "If you long for those balmy days when TVs looked like pieces of furniture, good news: This fall, IKEA will release Uppleva, a range of home entertainment systems that integrate a flat-screen full HD TV, 2.1 sound, and a Blu-ray player. Uppleva will come in three different designs, with a range of screen sizes starting at 24 inches. If the built-in Blu-ray player isn't enough, there are two USB and four HDMI ports down the side of the screen, and an empty 'bay' that can hold a games console, TiVo, or another set-top box of your choice. In true IKEA fashion, the whole caboodle will come in a range of colors (white, light wood, dark wood, black, and so on). Prices start at 6,500 Swedish Kroner (around $950) — presumably for the 24-inch version — which is a fairly good deal. Uppleva will only be available in a few European markets to start with, but the UK and North America should see it in early 2013."
An anonymous reader writes "The Next Web is reporting that Google Drive, the search giant's long anticipated cloud storage service, is set to launch next week. From the article: 'What's interesting though is that Google is planning to start everyone with 5 GB of storage. Of course you can buy more, but that trumps Dropbox's 2 GB that is included with every account. Dropbox does make it easy to get more space, including 23 GB of potential upgrades for HTC users. What's also interesting is the wording related to how the system will work. It's been long-thought that Windows integration will come easy, but that getting the Google Drive icon into the Mac a la Dropbox would be a bit harder. From what we're reading, Google Drive will work "in desktop folders" on both Mac and Windows machines, which still leaves the operation question unanswered.'"
MrSeb writes "Hot on the heels of the most successful storage mediums of all time — MiniDisc and Zip disks — Sony has announced the Optical Disc Archive, a system that seems to cram up to 30 Blu-ray discs into a single, one-inch-thick plastic cassette, which will have a capacity of between 300GB and 1.5TB. As far as I can tell, the main selling point of the Optical Disc Archive is, just like MiniDisc, the ruggedness of the cassettes. Optical discs themselves are fairly resistant to changes in temperature and humidity, and the cassettes are dust and water resistant. What is the use case for these 1.5TB MiniDiscs, though? In terms of pure storage capacity, tape drives are still far superior (you can store up to 5TB on a tape!) In terms of speed and flexibility, hard drives are better. If you're looking for ruggedness, flash-based storage is smaller, lighter, and can easily survive a dip in the ocean. The Optical Disc Archive might be good as extensible storage for TV PVRs, like TiVo and Sky+ — but as yet, we don't even know the cost of the system or the cassettes, and I doubt either will be cheap."
An anonymous reader writes "I designed this CPU clock to help people learn about how a CPU works. The Mechanical CPU Clock shows the basic building blocks of a CPU (ALU, buses, RAM, registers, and a Control Unit). It executes a set of instructions which will emulate a simple wall clock. A detailed build/explanation is available on instructables.com."
This is an interview with All Hands Active's Josh Williams. He shows us a project the group is doing in conjunction with Eastern Michigan University's Bright Futures Institute for the Study of Children, Families, and Communities. This is just one project, and maybe not the most exciting one they do, but it's something simple they can (and do) cart around to schools and other remote locations. They use a laser cutter for this simple project, not because it's really needed, Josh says, but because "any excuse to use a laser cutter is a good excuse."
itwbennett writes "Slashdot readers will recall that Carpathia Hosting, which is hosting the frozen data of 'up to 66 million users', would like to be released from that expense. But Judge Liam O'Grady has another idea: 'Lawyers for Megaupload, the U.S. Department of Justice (DOJ), Web hosting provider Carpathia Hosting and other groups fighting over who should maintain 1,100 servers formerly used by Megaupload should sit down and work out an arrangement,' O'Grady said Friday.' Stay tuned: The lawyers are due to report back in two weeks."
hypnosec writes "It seems fitting that the first batch of Raspberry Pi computers landed in the UK in the hands of school children based in Leeds as what many consider as another wave of grass-root computing revolution, another BBC Micro 2.0, begins. The Raspberry Pi has been designed from scratch to get anyone interested in computer programming to do so without forking out much; the base unit can connect to a television like the Commodore C64 or the Sinclair ZX81. According to the BBC, the first batch has been presented [Friday] by Eben Upton, the school project coordinator, in an event held at the Leeds offices of Premier Farnell, one of the official PI distributors."
CowboyRobot writes "For decades, rapid increases in storage, processor speed, and bandwidth have kept up with the enormous increases in computer usage. That could change however, as consumption finally outpaces the supply of these resources. It is instructive to review the 19th-century Economics theory known as Jevons Paradox. Common sense suggests that as efficiencies rise in the use of a resource, the consumption goes down. Jevons Paradox posits that efficiencies actually drive up usage, and we're already seeing examples of this: our computers are faster than ever and we have more bandwidth than ever, yet our machines are often slow and have trouble connecting. The more we have, the even more we use."
New submitter cb_is_cool writes "From the Beeb: 'The Pentagon has put in an order for prototype contact lenses that give users a much wider field of vision. The lenses are designed to be paired with compact heads up display units — glasses that allow images to be projected onto their lenses.' Hopefully, any mugger within 50 yards will have a red status bar above his head. 'The central part of each lens sends light from the HUD towards the middle of the pupil, while the outer part sends light from the surrounding environment to the pupil's rim. The retina receives each image in focus, at the same time."
jjp9999 writes "Bethesda announced they're bringing Kinect support to Skyrim. It doesn't sound like this will include motion detection. Rather, it will be around voice commands — tons of voice commands. It supports dragon shouts, trading, navigation, switching weapons, and a whole lot of other features that usually require you to assign hotkeys or to sort through menus. They also gave a brief hint at new content, stating they've 'been hard at work on creating the first set of game add-ons that will be exclusive to the Xbox 360. This additional content will add new quests, locations, features, and much more to the world of Skyrim.'"
New submitter Canazza writes "According to Develop, 'PC games giant Valve wants to "invent whole new gaming experiences" and is looking for people to help create new hardware, the Washington studio has confirmed. Off the back of a wave of speculation that the studio is building its own games console – a rumour which Valve has not specifically denied – the company now appears to be increasing capacity of its hardware development division.' Is Valve designing a new console? Or is this an expansion of its biometric controls research? Either way, something big is going down at Valve."
Elvis Presley, Johnny Cash, and other greats recorded at Sun Studio in Memphis, TN. It's still there (after a spotty history, including resale and re-opening in the late '80s) -- and it's still analog. Mostly analog, at least; a Pro Tools system is there for people who don't want to pay for an all-analog production. Thousands of tourists (I met a family from Norway who'd come to visit Graceland and Sun) descend on the old building each year just to see the place, and others come to record in the legendary space and what has become a boutique recording studio. I got to chat for a while with Sun recording engineer Matt Ross-Spang about working with the studio's lovingly gathered and restored recording gear, some of it nearly three times as old as he is. (An unexpected bonus: hanging out for a few hours in the Sun control room is a good way to bump into Fluke Holland, former drummer for Carl Perkins and Johnny Cash, who stopped in just after we stopped shooting.) Be warned: there are some bursts of rock-and-roll to listen through.
