Well as this plane appears to be built and flown in France, its electricity came from nuclear reactors. Not necessarily "green" energy but at least no CO2 was emitted producing it.
Facebook's Newest Datacenter Relies On Arctic Cooling 106
Nerval's Lobster writes "One year and seven months after beginning construction, Facebook has brought its first datacenter on foreign soil online. That soil is in Lulea, town of 75,000 people on northern Sweden's east coast, just miles south of the boundary separating the Arctic Circle from the somewhat-less-frigid land below it. Lulea (also nicknamed The Node Pole for the number of datacenters in the area) is in the coldest area of Sweden and shares the same latitude as Fairbanks, Alaska, according to a local booster site. The constant, biting wind may have stunted the growth of Lulea's tourism industry, but it has proven a big factor in luring big IT facilities into the area. Datacenters in Lulea are just as difficult to power and cool as any other concentrated mass of IT equipment, but their owners can slash the cost of cooling all those servers and storage units simply by opening a window: the temperature in Lulea hasn't stayed at or above 86 degrees Fahrenheit for 24 hours since 1961, and the average temperature is a bracing 29.6 Fahrenheit. Air cooling might prove a partial substitute for powered environmental control, but Facebook's datacenter still needed 120megawatts of steady power to keep the social servers humming. Sweden has among the lowest electricity costs in Europe, and the Lulea area reportedly has among the lowest power costs in Sweden. Low electricity prices are at least partly due to the area's proximity to the powerful Lulea River and the line of hydroelectric dams that draw power from it."
Microsoft Surface Pro Arrives Feb. 9 268
adeelarshad82 writes "According to Microsoft, the Surface Windows 8 Pro will be available for purchase on Feb. 9 in the U.S. and Canada. As anticipated, the Surface Pro will be slightly thicker than the Surface with Windows RT, and will weigh about two pounds. The tablet is powered with an Intel Core i5 processor and 4GB of memory. It also includes an 802.11 a/b/g/n dual band Wi-Fi, a stylus for pressure-sensitive input, dual 720p HD webcams, a full-sized USB 3.0 port, microSDXC slot, and mini DisplayPort. Since the Surface Pro runs Windows 8 Pro, it will work with your corporate infrastructure, as well as any older apps that you used on Windows XP to 7. In terms of pricing, the 64GB version will cost $899 while the 128GB will set you back by $999."
Hurricane Sandy Fails To Stop Line For iPad Mini Launch 103
Nerval's Lobster writes "Hurricane Sandy may have plunged part of New York City into darkness, drowned its basements and subway tunnels in saltwater, and even set part of a neighborhood on fire, but it couldn't stop New Yorkers from standing in line for hours to purchase the iPad Mini. Hundreds of people lined up in front of Apple's Fifth Avenue store for the chance to get their hands on the 7.9-inch device. According to CNET, which was on the scene and running a live-blog ahead of the store's 10 AM EST opening, 'many people in line are not fluent in English and are either Asian immigrants or visitors.' That opening was originally supposed to take place at 8 AM, and likely delayed because of the obvious citywide transportation issues. But for those in New York City who manage to get their sweaty hands on a new iPad Mini, there's an unusual wrinkle in the situation: power is still out below 39th Street in Manhattan, as well as portions of Brooklyn and Queens. (Apple's Fifth Avenue store is well above that power line.) While some private homes and businesses in electrified areas have set out power strips for strangers to charge their phones, it's hard to imagine a crowd of New Yorkers standing idly by while someone spends a significant amount of time charging a new tablet. Fortunately, many of those without power have found refuge with friends and family, if they haven't left the city altogether."
Golden Age of Silicon Valley Is Over With Facebook IPO 222
Hugh Pickens writes "Steve Blank, a professor at Berkeley and Stanford and serial entrepreneur from Silicon Valley, says that the the Facebook IPO is the beginning of the end for Silicon Valley as we know it. "Silicon Valley historically would invest in science, and technology, and, you know, actual silicon," says Blank. "If you were a good venture capitalist you could make $100 million." But there's a new pattern emerging created by two big ideas that will lead to the demise of Silicon Valley as we know it. The first is putting computer devices, mobile and tablet especially, in the hands of billions of people and the second is that we are moving all the social needs that we used to do face-to-face onto the computer and this trend has just begun. "If you think Facebook is the end, ask MySpace. Art, entertainment, everything you can imagine in life is moving to computers. Companies like Facebook for the first time can get total markets approaching the entire population." That's great for Facebook but it means Silicon Valley is screwed as a place for investing in advanced science. "If I have a choice of investing in a blockbuster cancer drug that will pay me nothing for ten years, at best, whereas social media will go big in two years, what do you think I'm going to pick?" concludes Blank. "The headline for me here is that Facebook's success has the unintended consequence of leading to the demise of Silicon Valley as a place where investors take big risks on advanced science and tech that helps the world. The golden age of Silicon valley is over and we're dancing on its grave.""
Treating Depression With Electrodes Inside the Brain 237
cowtamer writes "CNN has a writeup on a method of treating depression with implanted electrodes. If this works, we may be seeing a lot more of this type of technology in the future. '[The patients] were lightly sedated when the holes were drilled and the electrodes implanted, but they were awake to describe what they experienced. Several patients reported profound changes just minutes after the stimulator was turned on. One said the room suddenly seemed brighter and colors were more intense. Another described heightened feelings of connectedness and a disappearance of the void.' While I haven't looked into any of the academic literature on this, it seems that yet another Larry Niven Prediction has come true!"
The Laws of Physics Trump Traffic Laws 378
New submitter HeLLFiRe1151 sends this quote from Physics Central:
"Here's a practical application for your physics education: using math to successfully beat a traffic ticket in court. Dmitri Krioukov, a physicist based at the University of California San Diego, did just that to avoid paying a fee for (purportedly) running a stop sign. Krioukov not only proved his innocence, but he also posted a paper detailing his argument online (PDF) on the arXiv server."
KDE KWin May Drop Support For AMD Catalyst Drivers 148
An anonymous reader writes "The KWin window manager maintainer for KDE is looking at removing the legacy OpenGL 1.0 renderer from the KWin code-base due to the costs of supporting legacy hardware. This means dropping support for non-GL2+ graphics cards, which are all over six years old, but in the process would mean that for now there is no longer any support for the AMD Catalyst driver on the KDE desktop. Due to driver bugs, AMD's proprietary Catalyst software only works well with the GL1 renderer even though their latest hardware supports OpenGL 4."

Well in some contries it is easier - in Iceland over 90% of the electricity generation capacity is hydro so that would be a pretty good bet (the rest is geothermal and the odd diesel powered emergency generator thrown into the mix). One enterprising farmer even built a wind generator but that blew down in a storm after about a week - said he'd try it again, though.

Germany To End Nuclear Power By 2022 822
dcollins writes "Germany on Monday announced plans to become the first major industrialized power to shut down all its nuclear plants in the wake of the disaster in Japan, with a phase-out due to be wrapped up by 2022... Germany has 17 nuclear reactors on its territory, eight of which are currently off the electricity grid... Already Friday, the environment ministers from all 16 German regional states had called for the temporary order on the seven plants to be made permanent... Monday's decision is effectively a return to the timetable set by the previous Social Democrat-Green coalition government a decade ago. And it is a humbling U-turn for Merkel, who at the end of 2010 decided to extend the lifetime of Germany's 17 reactors by an average of 12 years, which would have kept them open until the mid-2030s."
Bad Science Writer Talks About the Placebo Effect *NSFW* 131
The Guardian newspaper's Bad Science columnist Dr. Ben Goldacre does a stand-up routine about medicine, the placebo effect, and the mysteries of the human body at Nerdstock. From a scientific standpoint, I can't accurately say how funny it is because I was told it was great before I saw it.

X Prize Foundation Wants AI Physician On Every Smartphone 245
kkleiner writes "One of the exciting ideas being tossed around recently at the X Prize Foundation is the creation of an Artificial Intelligence physician that you could access from your smartphone. Want to know if that rash on your leg is poison ivy or smallpox? Take a photo of it with your phone and ask the AI. The possibilities are enormous, especially for the billion plus people around the world who live more than a few hours' walk or drive from the nearest doctor."
This is one of four X Prizes in planning for the future. The other three are for an AI automobile driver, organ generation through stem cell use, and a deep sea submersible capable of exploring the sea floor.
