Company Wants To Put Power Plants In the Sky 223

Zothecula writes "Harvesting power from the wind and the sun is nothing new. We've seen flying wind turbines and solar power plants that aim to provide clean renewable energy. UK-based New Wave Energy has a bolder idea in the works. The company plans to build the first high altitude aerial power plant, using networks of unmanned drones that can harvest energy from multiple sources and transmit it wirelessly to receiving stations on the ground."

DARPA's Atlas Walking Over Randomness 76

mikejuk writes "Considering how long we have been trying to solve the problem, a robot walking is mostly amusing. Atlas is an impressive robot, evoking the deepest fears of sci fi. Watch as one of the DARPA challenge teams makes Atlas walk, unaided, on randomness. This video of Atlas was created by the Florida Institute For Human and Machine Cognition robotics team. It shows Atlas walking across a random collection of obstacles. Notice that even though it looks as if Atlas is supported by a tether, it isn't — as proved when it falls over at the end."

Intel Opens Doors To Rivals, Maybe 59

Rambo Tribble writes "In what appears to be a major reversal of policy, Intel's new president, Renee James, has indicated that Intel will be open to manufacturing chips based on rivals' designs. While the language is a bit tentative, this appears to open an opportunity for such as ARM to benefit from Intel's manufacturing expertise and technology." From the article: "James said Intel will evaluate prospective foundry clients on a 'deal by deal basis, not on an architecture by architecture basis.' That applies, James said, 'even in areas where there may be some competition with businesses that we’re in.'" Intel is already manufacturing FPGAs for Altera that include 64-bit ARM cores.

3D Systems and Motorola Team Up To Deliver Customizable 3D Printed Smartphones 12

MojoKid writes "Motorola is forging ahead with the concept of modular, customizable smartphones first put forth by designer Dave Hakkens with his Phonebloks concept. The company said recently that it was officially pursuing such an idea with Project Ara, and Motorola is already putting together important partnerships to make it happen. 3D Systems, a maker of 3D printers and other related products, has signed on to create a 'continuous high-speed 3D printing production platform and fulfillment system' for it. In other words, 3D Systems is going to print parts for the project, and what's more, the company has what appears to be an exclusive agreement to make all the enclosures and modules for Project Ara."

The Art of Apple, In Pictures 47

Hugh Pickens DOT Com writes "CNN reports that self-professed Apple fanatic Jonathan Zufi has published a book of photography profiling 500 of Apple's products through the years, because unlike other companies Apple has unapologetically focused on design says Zufi and he wants to celebrate that with his images. 'Other companies came up with the guts for a machine and then the engineers would find a way to stuff them into a box,' says Zufi. 'Steve Jobs started with the box and said, "You need to find a way to get the guts in."' It's an unlikely project for a software engineer with no formal photography training. Zufi bought new equipment and consulted with a professional as he began the project, which was four years in the making. 'I had a sudden memory of an old game I used to play in high school called Robot War,' says Zufi. 'I hopped on eBay to look for the game and an old Apple II to play it on, and that's how I ended up looking through old Apple products.' Zufi says that he approached each shot by looking for an image that would 'create that same emotional connection to that product, but maybe doesn't look like something you've seen before,' and says that his mission is to showcase the entire spectrum of products that Apple have sold to the public since 1976 – every desktop, every laptop, every notebook, monitor, iPod, iPad, iPhone, mouse, keyboard, modem, cable, port, adapter, docking station, memory expansion card — and that's just their hardware."

Intel's 128MB L4 Cache May Be Coming To Broadwell and Other Future CPUs 110

MojoKid writes "When Intel debuted Haswell this year, it launched its first mobile processor with a massive 128MB L4 cache. Dubbed "Crystal Well," this on-package (not on-die) pool of memory wasn't just a graphics frame buffer, but a giant pool of RAM for the entire core to utilize. The performance impact from doing so is significant, though the Haswell processors that utilize the L4 cache don't appear to account for very much of Intel's total CPU volume. Right now, the L4 cache pool is only available on mobile parts, but that could change next year. Apparently Broadwell-K will change that. The 14nm desktop chips aren't due until the tail end of next year but we should see a desktop refresh in the spring with a second-generation Haswell part. Still, it's a sign that Intel intends to integrate the large L4 as standard on a wider range of parts. Using EDRAM instead of SRAM allows Intel's architecture to dedicate just one transistor per cell instead of the 6T configurations commonly used for L1 or L2 cache. That means the memory isn't quite as fast but it saves an enormous amount of die space. At 1.6GHz, L4 latencies are 50-60ns which is significantly higher than the L3 but just half the speed of main memory."

Cloud Storage Comparison: Benchmarking From Afar 49

First time accepted submitter fasuin writes "Which is the most advanced cloud storage solution? Which is the impact of server locations? What are the benefits of advanced techniques to optimise data transfers? Researchers from Italy and The Netherlands have come out with a set of benchmarks that allowed them to compare Dropbox, CloudDrive, SkyDrive and Google Drive. Which is the best? You can check it by yourself by running the tests on your own if you like." What this kind of benchmarking can't well do, though, is predict which of these cloud storage companies are going to be around in five years, which might be at least as an important a factor.

Electric Cars: Drivers Love 'Em, So Why Are Sales Still Low? 810

cartechboy writes "The electric car challenge is what insiders call "getting butts in seats" — and a lot of butts today still belong to humans who are not yet buying electric cars. The big question is: Why? Surveys show drivers are interested in electric cars--and that they love them once they drive them. EVs also cost less to maintain (though more to buy in the first place) and many experts say they're simply nicer to drive. So what's the problem? Disinterested dealers, uneven distribution, limited supplies, and media bias are some potential challenges. Or maybe it's just lousy marketing--casting electric cars as a moral imperative or a duty, like medicine you have to take."

Another Casualty of Typhoon Haiyan: Geothermal Power 78

necro81 writes "Little known even in environmental circles is a renewable energy success story: five geothermal power plants on Leyte Island in the Philippines — each of which produces enough power for the entire island — that collectively produce more than 10% of the Philippines' total electrical demand. From boreholes deep underground comes pressurized water heated to 280 Celsius. At the surface it flashes into steam, turning one set of turbines, then cools and contracts to spin a second set of turbines. The low-grade steam is then condensed back into water and reinjected into the bedrock. But Typhoon Haiyan destroyed the cooling towers, snapped transmission towers, and scattered the employees."

A War Over Solar Power Is Raging Within the GOP 1030

mdsolar sends this quote from an article about the politics of solar energy: "Clean energy technology has always been an easy punching bag for conservatives. Propelled by growing strain of global warming denial within their party, Republicans in Congress have proposed to slash funding for renewable energy programs in half this year, and mocked the idea of a green economy as “groovy” liberal propaganda. Their argument, as laid out by House Republicans and libertarian organs like the Cato Institute and Reason magazine, is that the federal government shouldn't 'pick winners and losers' in the energy markets or gamble taxpayer dollars on renewable-energy loans to companies like Solyndra, the Silicon Valley solar panel manufacturer that went bankrupt in 2011 after receiving $535 million in federal loan guarantees. The assumption has always been that, without heavy government subsidies, renewable energy sources like solar and wind power would never be able to compete with fossil fuels. But something funny has happened to renewables that major power companies and their Republican allies didn't see coming. Over the past two years, the solar industry has skyrocketed, with one new solar unit installed every four minutes in the US, according to the renewable energy research group Greentech Media. The price of photovoltaic panels has fallen 62 percent since January 2011. Once considered a boutique energy source, solar power has become a cost-competitive alternative for many consumers, costing an average $143 per megawatt-hour, down from $236 in the beginning of 2011. Backed by powerful conservative groups, public utilities in several states are now pushing to curb the solar industry, and asking regulators to raise fees and impose new restrictions on solar customers. And as more people turn to rooftop solar as a way to reduce energy costs—90,000 businesses and homeowners installed panels last year, up 46 percent from 2011—the issue is pitting pro-utilities Republicans against this fledgling movement of libertarian-minded activists who see independent power generation as an individual right. In other words, the fight over solar power is raging within the GOP itself."
Hardware

Elevation Plays a Role In Memory Error Rates 190

alphadogg writes "With memory, as with real estate, location matters. A group of researchers from AMD and the Department of Energy's Los Alamos National Laboratory have found that the altitude at which SRAM resides can influence how many random errors the memory produces. In a field study of two high-performance computers, the researchers found that L2 and L3 caches had more transient errors on the supercomputer located at a higher altitude, compared with the one closer to sea level. They attributed the disparity largely to lower air pressure and higher cosmic ray-induced neutron strikes. Strangely, higher elevation even led to more errors within a rack of servers, the researchers found. Their tests showed that memory modules on the top of a server rack had 20 percent more transient errors than those closer to the bottom of the rack. However, it's not clear what causes this smaller-scale effect."

Users Identified Through Typing, Mouse Movements 149

mask.of.sanity writes "Users can be identified with a half percent margin of error based on the way they type. The research work has been spun into an application that could continuously authenticate users (PDF), rather than just relying on passwords, and could lock accounts if another person jumped on the computer. Researchers are now integrating mouse movements and clicks, and mobile touch patterns into the work."

Researcher Shows How GPUs Make Terrific Network Monitors 67

alphadogg writes "A network researcher at the U.S. Department of Energy's Fermi National Accelerator Laboratory has found a potential new use for graphics processing units — capturing data about network traffic in real time. GPU-based network monitors could be uniquely qualified to keep pace with all the traffic flowing through networks running at 10Gbps or more, said Fermilab's Wenji Wu. Wenji presented his work as part of a poster series of new research at the SC 2013 supercomputing conference this week in Denver."

Ask Slashdot: How Reproducible Is Arithmetic In the Cloud? 226

goodminton writes "I'm research the long-term consistency and reproducibility of math results in the cloud and have questions about floating point calculations. For example, say I create a virtual OS instance on a cloud provider (doesn't matter which one) and install Mathematica to run a precise calculation. Mathematica generates the result based on the combination of software version, operating system, hypervisor, firmware and hardware that are running at that time. In the cloud, hardware, firmware and hypervisors are invisible to the users but could still impact the implementation/operation of floating point math. Say I archive the virutal instance and in 5 or 10 years I fire it up on another cloud provider and run the same calculation. What's the likelihood that the results would be the same? What can be done to adjust for this? Currently, I know people who 'archive' hardware just for the purpose of ensuring reproducibility and I'm wondering how this tranlates to the world of cloud and virtualization across multiple hardware types."

New Smart Glasses Allow Nurses To See Veins Through Skin 124

Lucas123 writes "Epson and Evena Medical today unveiled a new smart-glass technology that allows nurses to see 'through' a patient's skin to the vasculature beneath in order to make intravenous placement easier. The Eyes-On Glasses System is based on Epson's Moverio Smart Glasses Technology, an Android-based, see-through wearable display launched earlier this year that allows users to interact with apps and games. The glasses use near-infrared light to highlight deoxygenated hemoglobin in a patient's veins and capture the images with two stereoscopic cameras. The cameras then project the vein images onto the see-through glass screens. The glasses can store the images and video and transfer them wirelessly to a patient's electronic health record, and they also come with dual built-in speakers for video conferencing."

Ask Slashdot: What's On Your Hardware Lab Bench? 215

50000BTU_barbecue writes "I made a comment a few days ago in a story basically saying the oscilloscope is dead. While that's a bit dramatic, I've found that over the last 20 years my oscilloscopes have been 'on' less and less. Instead, I use a combination of judicious voltage measurements, a logic analyzer and a decent understanding of the documentation of the gadget I'm working on. Stuff is just more and more digital and microcontroller-based, or just so cheap yet incredibly integrated that there's no point in trying to work on it. (I'm thinking RC toys for example. Undocumented and very cheap. Doesn't work? Buy another.) While I still do old-school electronics like circuit-level troubleshooting (on old test gear), that's not where the majority of hobbyists seem to be. Yet one thing I keep hearing is how people want an oscilloscope to work on hardware. I think it's just not that necessary anymore. What I use most are two regulated DC lab supplies, a frequency counter, a USB logic analyzer, a USB I2C/SPI master, and a USB-RS-232 dongle. That covers a lot of modern electronics. I have two oscilloscopes, a 100MHz two-channel stand-alone USB unit and a 1960s analog plug-in-based mainframe that is a '70s hacker dream scope. But I rarely use them anymore. What equipment do hardware folks out there use the most? And would you tell someone trying to get into electronics that they need a scope?"

Not All USB Power Is Created Equal 240

jfruh writes "We've reached a point in our electronic lives where most of our gadgets draw power from a USB cable, and we have lots of USB ports to choose from — some of which live on other gadgets, some of which live on adapters that plug into your wall or car. But those ports supply wildly varying amounts of power, which can result in hours of difference in how long it takes your phone to charge. The Practical Meter, the product of a successful Kickstarter campaign, can help you figure out which power sources are going to juice up your gadgets the fastest."
