chrb writes "Scientists from the California Institute of Technology and the Swiss Federal Institute of Technology have unveiled a new solar reactor prototype that directly converts carbon dioxide or water into carbon monoxide or hydrogen, respectively. The abstract is available in Science. Quoting the BBC writeup: 'The prototype ... uses a quartz window and cavity to concentrate sunlight into a cylinder lined with cerium oxide, also known as ceria. Ceria has a natural propensity to exhale oxygen as it heats up and inhale it as it cools down. If, as in the prototype, carbon dioxide and/or water are pumped into the vessel, the ceria will rapidly strip the oxygen from them as it cools, creating hydrogen and/or carbon monoxide. ...The prototype is grossly inefficient, the fuel created harnessing only between 0.7% and 0.8% of the solar energy taken into the vessel. Most of the energy is lost through heat loss through the reactor's wall or through the re-radiation of sunlight back through the device's aperture. But the researchers are confident that efficiency rates of up to 19% can be achieved through better insulation and smaller apertures. Such efficiency rates, they say, could make for a viable commercial device."

1sockchuck writes "Lightning, floods, car crashes, and coding snafus had starring roles in major Internet outages of 2010. Data Center Knowledge reviews the year's business downtime, including outages for banking and e-commerce sites and several incidents that knocked state government services offline. Meanwhile, Pingdom focuses on downtime for major social media sites and Wikileaks. Then there's the guy who got drunk and shot up a server."

Csiko writes "The ingredients in this do-it-yourself Christmas project are a felt pen, a bunch of old CDs, an embedded microcontroller (MCU), some LEDs and a big portion of nerdism. While the gyroscope spins, the MCU controls the LEDs so that a writing appears in real-time. Nice project, but it definitely needs a nerd girlfriend to appreciate it."

Hugh Pickens writes "Federal News Radio reports that in Metropolis, Illinois, the nation's only site for refining uranium for eventual use in nuclear power plants, some 230 union workers locked out by the company since last June take turns picketing and warning of possible toxic releases into the community while they're not at their jobs. Even in better times, the plant has been a source of concern. In September 2003, toxic hydrogen fluoride was released in an accident. Three months later, seepage of mildly radioactive gas sent four people to the hospital and prompted the evacuation of nearby residents. Now a recent safety inspection by the Nuclear Regulatory Commission found that temporary workers brought in by Honeywell weren't properly trained and were cheating on tests, and that Honeywell had neglected to report liquids that were released into the air. Metropolis' troubles began last spring when efforts to negotiate a new contract broke down at the Honeywell plant. Honeywell opted not to let the union employees work without a contract, citing the lack of bargaining progress and what it called the union's refusal to agree to provide 24 hours of notice before any strike."

theodp writes "Microsoft's Kinect has been out for less than two months and already there's an adult company looking to produce a 3-D sex game for the Xbox 360 console. But Microsoft immediately shot down any speculation that the game will pass the certification process. 'This isn't the first example of a technology being used in ways not intended by its manufacturer, and it won't be the last,' a Microsoft spokesman said in a statement. 'Microsoft did not authorize or license its technology for this use. Xbox is a family friendly games and entertainment console and does not allow Adults Only content to be certified for use on its platform, and would not condone this type of game for Kinect.'"

Hugh Pickens writes "Steve Johnson writes in the Mercury News that microchips are going into a staggering array of once decidedly low-tech items — from gravestone markers and running shoes to fish lures and writing pens. In the future, 'where won't we find chips?' asks analyst Jordan Selburn. 'The answer is pretty close to nowhere.' For example, one company sells a coin-size, stainless steel-encased microchip for gravestone markers that tells the dead person's story in text, photos, video or audio histories, which visitors can access by pointing their Internet-enabled cell phones at it. The company says it has sold thousands of 'Memory Medallions.' There's AquaOne Technologies, who sell a toilet containing chips that automatically shut off the water when it springs a leak or starts to overflow, but Japanese company Toto goes one better with an intelligent toilet that gathers health-related data from the user's urine. Pro-Troll puts a chip in its fish lures that 'duplicates the electrical nerve discharge of a wounded bait fish,' prompting other fish to bite it."

nateman1352 writes with a bit from TechSpot: "Intel has been trying to cut itself a slice of the mobile market for years, and it seems the company is finally making some headway. During a conference yesterday, Intel CEO Paul Otellini revealed that the company's Atom platform will ship in over 35 tablets starting early next year. The chipmaker has partnered with more than a dozen manufacturers who will launch slates running Windows [or] Android as well as Intel's own MeeGo operating system." The article lists Toshiba, Dell, Fujitsu, Lenovo, Asus, AT&T, Cisco, and Acer as developing Atom-based tablets.

Zack writes "Dropbox has finally released version 1.0. The new version comes with hundreds of bug fixes, including invalid file names on Windows, weird Unicode normalizations, Word and Excel file locking, abnormal symlinks hierarchies, and case sensitive file systems on Mac. It also adds TrueCrypt support, a Rainbow Shell that offers support for extended attributes, selective sync, a new installation wizard, and reduces resource usage."

An anonymous reader writes "Intel's new Sandy Bridge processors have a new feature that the chip giant is calling Anti-Theft 3.0. The processor can be disabled even if the computer has no Internet connection or isn't even turned on, over a 3G network. With Intel anti-theft technology built into Sandy Bridge, David Allen, director of distribution sales at Intel North America, said that users have the option to set up their processor so that if their computer is lost or stolen, it can be shut down remotely."

schliz writes "Researchers have made headway into developing spintronic RAM by successfully transferring spin information from an electron to a more robust atomic nucleus and accessing the information 2,000 times in 100 seconds before it decayed (abstract). The demonstration was conducted using phosphorus-doped silicon in a highly magnetized, low-temperature environment (8.59 Tesla, -269.5 degrees Celsius). Other researchers have achieved spin lifetimes of 30 hours in a weaker magnetic field (0.3 Tesla)."

An anonymous reader writes "This year we've seen molten salt power plants start to pick up steam around the world, and now the technology is heating up stateside — California just approved its first molten salt energy plant. Designed by SolarReserve, the plant uses heliostats to focus thermal energy on a power tower filled with salt, which is able to reach very high temperatures (over 1000 degrees Fahrenheit) and can hold heat for an extraordinary length of time. Heat from this reserve of molten salt can then be pumped through a steam generator to provide on-demand energy long after the sun has set."

Whammy666 writes "JBI, Inc. announced that it has entered into a formal Consent Order with the New York State Department of Environmental Conservation (DEC) Region 9, which will allow the Company to immediately run its Plastic2Oil (P2O) process commercially and begin construction of an additional processor at its Niagara Falls, New York P2O facility. JBI has developed a process that takes waste plastic destined for landfills and converts it into diesel fuel, gasoline, and natural gas with very little residue. The process is said to be very efficient thanks to a special catalyst developed by JBI and an attention to process optimization. That plastic water bottle you tossed in the trash could soon be fueling your car instead of sitting in a landfill for 1000 years."

coondoggie writes "This one sounds a bit like really wishful thinking. The US Department of Energy today announced $30 million for research projects that would develop advanced biofuels that could replace gasoline or diesel without requiring special upgrades or changes to the vehicle or fueling infrastructure. The $30 million would be spent over the next four years to support as many as five 'traditionally high-risk biofuels projects,' such as converting biomass into biofuels and bioproducts to be eventually used for hydrocarbon fuels and chemicals."

adeelarshad82 writes "While Google has made it clear that Cr-48 is nothing more than a test prototype, it was interesting to see the machine Google used to demonstrate Chrome OS. Out of the box, the Cr-48 conjures images of the Black Apple MacBook, from the plain, rubberized chassis to what looks like the same chiclet-style keyboard. The 12-inch notebook weighs about 3.8lbs and comes with a clickpad which recognizes one finger as a left click, while a two-finger tap triggers a right-click function. The laptop obviously contains a hard drive for storing backup data, but the capacity is unknown. The notebook comes with a lone USB port on the right side, which has limited functionaly. For now, thumb drives, hard drives, cameras, printers and other USB peripherals do not work with Cr-48. Google is working on getting its Chrome OS to recognize storage drives, but it's a work in progress. Once Chrome OS does recognize storage drives, users can probably install other OSes on Cr-48 for fun. Video playback seems to struggle with Hulu videos, while YouTube clips were okay. The device operates at a 1,280x800 resolution, which means the Cr-48 can theoretically support 720p video playback, but the videos were capped at 480p." Engadget posted photos a Cr-48 teardown if you'd like a look at its guts. An article at InfoWorld suggests Google needs to work on the cloud offerings underpinning the device.

waderoush writes "A startup called Tibion in Sunnyvale, CA, has begun selling battery-powered robotic exoskeletons that help stroke victims with one-sided weakness relearn how to stand, sit, walk, and negotiate stairs. The leg isn't a permanent attachment; the company says patients who use the device for 45 minutes a week for four weeks experience significant gains in walking speed that persist and even improve months after the treatment. They believe that the $40,000 device — which includes sensors that respond to subtle signs of user intentions, such a shift in weight — provides feedback that triggers neuroplasticity, the brain's ability to rewire itself to repair damage."

An anonymous reader writes "CNN is reporting on the new training mannequins being used by the United States military. Advances in technology have allowed the training dummies to become ultra-realistic. From the article: 'New battery-operated, remote-controlled mannequins can simulate bleeding and breathing, and they have blinking eyes that dilate. Medics can test their skills on these life-like mannequins. The new units, which are packed with technology, are used at 23 US Army Medical Simulation Training Centers as part of a program to teach lifesaving techniques to medics and nonmedical personnel. A Pentagon study says the training program has saved 1,000 soldiers' lives in combat, said Lt. Col. Wilson Ariza, manager of the US Army Medical Simulation Project.'"
