MikeChino writes "Australia-based EnviroMission Ltd recently announced plans to build two solar updraft towers that span hundreds of acres in La Paz County, Arizona. Solar updraft technology sounds promising enough: generate hot air with a giant greenhouse, channel the air into a chimney-like device, and let the warm wind turn a wind turbine to produce energy. The scale of the devices would be staggering — each plant would consist of a 2,400 foot chimney over a greenhouse measuring four square miles. The Southern California Public Power Authority has approved EnviroMission as a provider, although there’s still plenty of work to be done before the $750 million, 200 megawatt project can begin."

Barence writes with some more information on a device mentioned in passing earlier today: "The enTourage eDGe eBook reader was the highlight of the CES Unveiled event, which gives journalists a sneak preview of what’s set to appear this year’s show. It has a 9.7in e-paper display on one side and a 10.1in LCD screen on the other, both of which are touchscreens, allowing you to annotate eBooks with handwritten notes or scan through web pages with the flick of a finger on the LCD screen. In a brief hands-on demonstration, the eDGe showed several clever touches, such as allowing you to perform a Google search on the term using the built-in web browser, and then link the search results to the eBook page, which is a great research tool for students reading academic texts. It's an Android device, too."

hollywoodb writes "The first carbon tax to reduce the greenhouse gases from imports comes not between two nations, but between two states. Minnesota has passed a measure to stop carbon at its border with North Dakota. To encourage the switch to clean, renewable energy, Minnesota plans to add a carbon fee of between $4 and $34 per ton of carbon dioxide emissions to the cost of coal-fired electricity, to begin in 2012 ... Minnesota has been generally pushing for cleaner power within its borders, but the utility companies that operate in MN have, over the past decades, sited a lot of coal power plants on the relatively cheap and open land of North Dakota, which is preparing a legal battle against Minnesota over the tariff."

LordofEntropy writes "Blu-ray.com reports that Sony and Panasonic have announced a new optical disc evaluation technology that increases capacity from 25GB to 33.4GB. The tech uses existing Blu-ray diodes and is accomplished via firmware upgrade. The article says it is not known if and when the upgrade will be adopted into the Blu-ray spec. However, given that Sony and Panasonic are behind it, 'it will likely happen later this year.'"

An anonymous reader writes "USB Flash drives with hardware based AES 256-bit encryption manufactured by Kingston, SanDisk and Verbatim have reportedly been cracked by security firm SySS. These drives are advertised to meet security standards suitable for use with sensitive US Government data (unclassified, of course) as emphasized by the FIPS 140-2 Level 2 certificate issued by the US National Institute of Standards and Technology (NIST). It looks likes the Windows-based password entry program always sends the same character string to the drive after performing various crypto operations."

DCFC writes "The Consumerist deconstructs the appalling 'optimization service' that Best Buy has been pushing on consumers in recent weeks. The retailer charges 40 bucks to give you a slower PC, and make bizarre claims that it makes it go 200% faster. 'We ran the 3DMark 2003 graphics benchmark on each laptop, comparing optimized and non-optimized settings. For two of our samples, the Gateway and Toshiba, performance changes were negligible. On the Asus laptop, however, optimized tests actually scored about 32% worse than the non-optimized setup. We have been unable to isolate the source of this performance change. On none of the three tested laptops did the optimized settings give a performance boost in our test.'"

theodp writes "Freescale Semiconductor has designs on new smartbook tablet computers, and to prove it, it's rolling out a second-generation reference design at the Consumer Electronics Show. For under $200, Freescale envisions an instant-on device with persistent connectivity and all-day battery life with the following additional features: 7" (1024 x 600) touch screen, Freescale i.MX515 processor (based on ARM Cortex-A8 core), 802.11 b/g/n, Bluetooth 2.1, GPS, 3G modem (optional), 512 MB DDR2 memory, 4GB to 64GB internal storage, removable micro SD, 3 Mpixel camera (video up to VGA 30fps), 3-axis accelerometer, ambient light sensor, Adobe Flash support, Android or Linux OS."

MojoKid writes "Intel has officially launched their new Core i5 and Core i3 lineup of Arrandale and Clarkdale processors today, for mobile and desktop platforms respectively. Like Intel's recent release of the Pinetrail platform for netbooks, new Arrandale and Clarkdale processors combine both an integrated memory controller (DDR3) and GPU (graphics processor) on the same package as the main processor. Though it's not a monolithic device, but is built upon multi-chip module packaging, it does allow these primary functional blocks to coexist in a single chip footprint or socket. In addition, Intel beefed up their graphics core and it appears that the new Intel GMA HD integrated graphics engine offers solid HD video performance and even a bit of light gaming capability."

theodp writes "Four decades ago, the NSF-sponsored PLATO Elementary Reading Curriculum Project (pdf) provided Illinois schoolchildren with reading lessons and e-versions of beloved children's books that exploited networked, touch-sensitive 8.5"x8.5" bit-mapped plasma screens, color images, and audio. Last week, the Today Show promoted the TeacherMate — a $100 gadget that's teaching Illinois schoolchildren to read and do math using its 2.5" screen and old-school U-D-L-R cursor keys — as a revolution in education. Has early childhood education managed to defy Moore's Law?"

mrshermanoaks writes "When the choices for developing nuclear energy were being made, we went with uranium because it had the byproduct of producing plutonium that could be weaponized. But thorium is safer and easier to work with, and may cause a lot fewer headaches. 'It's abundant — the US has at least 175,000 tons of the stuff — and doesn't require costly processing. It is also extraordinarily efficient as a nuclear fuel. As it decays in a reactor core, its byproducts produce more neutrons per collision than conventional fuel. The more neutrons per collision, the more energy generated, the less total fuel consumed, and the less radioactive nastiness left behind. Even better, Weinberg realized that you could use thorium in an entirely new kind of reactor, one that would have zero risk of meltdown. The design is based on the lab's finding that thorium dissolves in hot liquid fluoride salts. This fission soup is poured into tubes in the core of the reactor, where the nuclear chain reaction — the billiard balls colliding — happens. The system makes the reactor self-regulating: When the soup gets too hot it expands and flows out of the tubes — slowing fission and eliminating the possibility of another Chernobyl. Any actinide can work in this method, but thorium is particularly well suited because it is so efficient at the high temperatures at which fission occurs in the soup.' So why are we not building these reactors?"

The BBC is reporting that the netbook craze may already be nearing the end of its run. Citing rising netbook prices and many other evolving technologies that can potentially fill that gap, some critics think that the limited power of netbooks will ultimately bring about the quick demise of the once popular device. "Ian Drew, spokesman for chip designer Arm, also believes netbooks are in for a shake-up. Consumers, he said, were chafing against the restrictions that using a netbook imposed on them. 'We have failed the consumer because we have imposed constraints on them,' he said. Changing web habits and greater use of social media will mean consumers will be looking for gadgets that are tuned to specific purposes. 'It will be a lot of different machines for a lot of different people,' he said. 'This whole market will be exploding in the next couple of years.' Impetus for this change will come, he believes, from the phone world where many, many types of gadgets are already blooming."

storagedude writes "Access to data isn't keeping pace with advances in CPU and memory, creating an I/O bottleneck that threatens to make data storage irrelevant. The author sees phase change memory as a technology that could unseat storage networks. From the article: 'While years away, PCM has the potential to move data storage and storage networks from the center of data centers to the periphery. I/O would only have to be conducted at the start and end of the day, with data parked in memory while applications are running. In short, disk becomes the new tape."

An article at Gamasutra provides some details on the hardware Mythic uses to power Warhammer Online, courtesy of Chief Technical Officer Matt Shaw and Online Technical Director Andrew Mann. Quoting: "At any given time, approximately 2,000 servers are in operation, supporting the gameplay in WAR. Matt Shaw commented, 'What we call a server to the user, that main server is actually a cluster of a number of machines. Our Server Farm in Virginia, for example,' Mann said, 'has about 60 Dell Blade chassis running Warhammer Online — each hosting up to 16 servers. All in all, we have about 700 servers in operation at this location.' ... 'We use blade architecture heavily for Warhammer Online,' Mann noted. 'Almost every server that we deploy is a blade system. We don't use virtualization; our software is somewhat virtualized itself. We've always had the technology to run our game world across several pieces of hardware. It's application-layer clustering at a process level. Virtualization wouldn't gain us much because we already run very close to peak CPU usage on these systems.' ... The normalized server configuration — in use across all of the Mythic-managed facilities — features dual Quad-Core Intel Xeon processors running at 3 GHz with 8 GB of RAM."

It really seems to work, check the right hand side of the graph in the video." It's not that crazy: cheap antenna boosting (for USB WiFi dongles, Bluetooth, and more) has been elevated to a fine art in New Zealand.

kkleiner writes "The Shadow Dextrous Hand is a robotic arm that allows for fine motor control and precise movements. It's accurate enough to pick up an egg, screw in a light bulb, or thread a needle. Even cooler, researchers can control it with a 'Cyber glove,' allowing for 24 distinct human movements that mimic the user's own hand. A British based company, Shadow, has been displaying the hand for several years now, and recently demonstrated its latest model at IREX 2009. The hand, toted as the world's most advanced, is available for sale to researchers (pricing has not been made public)."

theodp writes "Many municipalities have switched to LED traffic signals because they burn brighter, last longer and use 90% less energy than incandescent bulbs. But they also emit less heat, meaning they sometimes have trouble melting snow, causing problems across the Midwest. In Wisconsin, snow blanketed LED traffic lights in some towns, leading to crashes at intersections where drivers weren't sure whether to stop or go. The unintended consequences of the green technology were also identified as a 'contributing factor' in the death of an Illinois woman hit by a driver who blamed the snow-covered energy-efficient signal for giving the appearance of a normal green light instead of a left-turn signal. 'We can remove the snow with heat, but the cost of doing that in terms of energy use has not brought any enthusiasm from cities and states that buy these signals,' said the CEO of an LED traffic-signal manufacturer. 'They'd like to be able to take away this issue, but they don't want to spend the money and lose the savings.' In the meantime, some towns are addressing sporadic problems by dispatching crews to remove snow or ice from signals using poles, brooms, and heating devices." We were discussing these recently at the office — several folks in the building are red/green color blind and different street lights are differently distinguishable.

Luminous Coward writes "As previously discussed on Slashdot, according to AnandTech and The Tech Report, hard disk drive manufacturers are now ready to bump the size of the disk sector from 512 to 4096 bytes, in order to minimize storage lost to ECC and sync. This may not be a smooth transition, because some OSes do not align partitions on 4K boundaries."

With the recent announcement of OLPC's shift in focus, many are criticizing the nonprofit's attempt to design what could be seen as unrealistic hardware at an impossible price point. "The OLPC project has become an unrealistic hardware 'dream' and lost its focus on education, wrote blogger Wayan Vota on OLPC News, which has followed the OLPC since its inception. The project comes up with unrealistic hardware designs and price points that destroy its purpose even more, he wrote. 'Excuse me if I get mad at the XO-3 hype. I'm angry at the energy devoted to fantasy XO hardware instead of OLPC educational reality. I miss the original OLPC Mission, where children, not computers, controlled our dreams,' Vota wrote."
