NASA Power Beaming Challenge is On For November 2nd 81

carstene writes "The NASA Centennial Challenge Powered Beaming competition, to develop technology for uses such as a space elevator, or to power a rover in a shadowed crater on the moon, was delayed indefinitely due to trouble setting up the kilometer-high race track. It has now had the kinks worked out and is rescheduled for the week of November 2nd. The competition involves using a high-power laser to beam power to a robot that climbs a kilometer-high cable attached to a helicopter. The competition was previously covered on Slashdot."

NCSU's Fingernail-Size Chip Can Hold 1TB 227

CWmike writes "Engineers from North Carolina State University have created a new fingernail-size chip that can hold 1 trillion bytes (a terabyte) of data. They said their nanostructured Ni-MgO system can store up to 20 high-definition DVDs or 250 million pages of text, 'far exceeding the storage capacities of today's computer memory systems.' Using the process of selective doping, in which an impurity is added to a material whose properties consequently change, the engineers worked at nanoscale and added metal nickel to magnesium oxide, a ceramic. The resulting material contained clusters of nickel atoms no bigger than 10 square nanometers — a pinhead has a diameter of 1 million nanometers. The discovery represents a 90% size reduction compared with today's techniques, and an advancement that could boost computer storage capacity. 'Instead of making a chip that stores 20 gigabytes, you have one that can handle one terabyte, or 50 times more data,' said the team's leader, Jagdish 'Jay' Narayan, director of the National Science Foundation Center for Advanced Materials and Smart Structures at the university."

The Risks and Rewards of Warmer Data Centers 170

1sockchuck writes "The risks and rewards of raising the temperature in the data center were debated last week in several new studies based on real-world testing in Silicon Valley facilities. The verdict: companies can indeed save big money on power costs by running warmer. Cisco Systems expects to save $2 million a year by raising the temperature in its San Jose research labs. But nudge the thermostat too high, and the energy savings can evaporate in a flurry of server fan activity. The new studies added some practical guidance on a trend that has become a hot topic as companies focus on rising power bills in the data center."

Skiing Robot May Not Be Useful, But Fun To Watch 64

kkleiner writes "Bojan Nemec from the Jozef Stefan Institute in Slovenia recently presented his skiing robot at the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS). The robot won't be winning skiing records anytime soon and its usefulness as a ski instructor or in any other capacity seems quite a ways off. Nonetheless, the videos of this robot taking a ride down the ski slopes are well worth watching. In case you are wondering, this is a completely different robot than the one Slashdot covered earlier."

Toyota Experimenting With Joystick Control For Cars 609

alphadogg writes "Today it's the stuff of video games, but Toyota is experimenting with joystick control for a new breed of compact cars and transporters. The world's biggest car maker built the technology into a couple of concept vehicles that were on display Wednesday at the Tokyo Motor Show. The FT-EV II, which got its world premiere at the event, is a compact electric vehicle designed for short trips. The car retains seats for four passengers despite being much more compact than most other cars, and packs drive-by-wire technology so it can be controlled with a joystick. The car's steering, braking and acceleration can be controlled by hand so foot pedals aren't needed, freeing up space to provide more legroom for the driver."

Windows 7 On Multicore — How Much Faster? 349

snydeq writes "InfoWorld's Andrew Binstock tests whether Windows 7's threading advances fulfill the promise of improved performance and energy reduction. He runs Windows XP Professional, Vista Ultimate, and Windows 7 Ultimate against Viewperf and Cinebench benchmarks using a Dell Precision T3500 workstation, the price-performance winner of an earlier roundup of Nehalem-based workstations. 'What might be surprising is that Windows 7's multithreading changes did not deliver more of a performance punch,' Binstock writes of the benchmarks, adding that the principal changes to Windows 7 multithreading consist of increased processor affinity, 'a wholly new mechanism that gets rid of the global locking concept and pushes the management of lock access down to the locked resources,' permitting Windows 7 to scale up to 256 processors without performance penalty, but delivering little performance gains for systems with only a few processors. 'Windows 7 performs several tricks to keep threads running on the same execution pipelines so that the underlying Nehalem processor can turn off transistors on lesser-used or inactive pipelines,' Binstock writes. 'The primary benefit of this feature is reduced energy consumption,' with Windows 7 requiring 17 percent less power to run than Windows XP or Vista."

Robot Controlled By Human Brain Cells 86

destinyland writes "There's a new experiment from the British researchers who created a robot controlled by cultured rat neurons. They're now using a line of human brain neurons to control robots. The neurons are placed onto a multi-electrode dish that registers the neurons' electric signals. 'Every time the robot nears an object, the electrodes generate signals to stimulate the brain. In response, the brain's output is used to drive the wheels of the robot left and right so that it avoids hitting objects. The robot has no additional control from a human or a computer — its sole means of control is from its own brain.'"

A New Robotic Hand That Can "Feel" 112

Dyne09 writes "The BBC is running a video report about a group of Swiss and Italian scientists who have created the 'Smart Hand,' a robotic hand with forty sensors that 'connect directly to the brain.' Though fuzzy on the details, the report says the hand provides sensor feedback to a willing test subject, a 22-year-old man who lost his hand to cancer three years ago. How long until we have access to Star Wars-esque robotic limbs?"

Ultracapacitor Bus Recharges At Each Stop 419

TechReviewAl writes "A US company and its Chinese partner are piloting a bus powered by ultracapacitors in Washington DC. Ultracapacitors lack the capacity of regular batteries but are considerably cheaper and can be recharge completely in under a minute. Sinautec Automobile Technologies, based in Arlington, VA, and its Chinese partner, Shanghai Aowei Technology Development Company, have spent the past three years demonstrating the approach with 17 municipal buses on the outskirts of Shanghai. The executive director of Sinautec touts the energy efficiency of this approach: 'Even if you use the dirtiest coal plant on the planet [to charge an ultracapacitor], it generates a third of the carbon dioxide of diesel.'"

What Desktop Search Engine For a Shared Volume? 232

kriston writes 'Searching data on a shared volume is tedious. If I try to use a Windows desktop search engine on a volume with hundreds of gigabytes the indexing process takes days and the search results are slow and unsatisfying. I'm thinking of an agent that runs on the server that regularly indexes and talks to the desktop machines running the search interface. How do you integrate your desktop search application with your remote file server without forcing each desktop to index the hundred gigabyte volume on its own?'

Xbox 360 Update Will Lock Out Unauthorized Storage 435

itwbennett writes "The other shoe has dropped on the upcoming preview program for the next Xbox 360 update and it's going to cost you. In a post on the Major Nelson blog, Xbox's Larry Hryb reveals that this next update will lock-out unauthorized storage devices. As blogger Peter Smith reminds us, 'the Xbox 360 comes in two (currently) SKUs, one with a hard drive, and one without. The drive-less Xbox 360 Arcade unit is cheap ($199) but to realistically use it, you'll need to buy a "Memory Unit" (basically a proprietary USB stick) or an Xbox hard drive.... A 512 MB Microsoft branded Memory Unit goes for $29.99 at BestBuy.com. A 2 GB third party Memory Unit from Datel goes for $39.99, and the Datel unit is expandable using microSD cards....If you bought the Datel and it's full of data, between now and the launch of the new update you're going to have to run out and buy 4 of the Microsoft units at $29.99 each, or more likely, pick up the $99.99 60GB Live Starter Pack for Xbox 360.'"

Sony Demo'ing 360 Degree 3-D Tabletop Display 102

JoshuaInNippon writes "Sony announced via a Japanese press release that they will be showing off a prototype of a tabletop 360 degree 3-D display that can be seen in any direction without special glasses at the Digital Content Expo 2009 in Tokyo, from October 22-25. The device is quite small, at just over 10 inches tall and 5 inches in diameter. The display, using LEDs, currently supports an image that is 96 pixels wide by 128 pixels tall, with 24-bit full color. Sony also says it could have a number of applications, such as a digital sign, a digital frame, a medical display, or a virtual pet. Looking at the product image, who else wants to bet on the latter?)"

iRobot Introduces Morphing Blob Robot 177

Aristos Mazer sends word of research out of iRobot on a "chembot," or morphing blob robot, that looks like dough and moves by shifting its sides from solid-like to liquid-like states. This will allow it, in theory and after lots of refinement, to pass through cracks by squeezing. iRobot calls the new technique "jamming." The research project was funded by DARPA. The video clearly shows the early stage the work is in, but when you think about it the possibilities are a little unsettling.

A Step Closer To Cheap Nuclear Fusion 404

ewsnow writes "The Focus Fusion Society reports that the scientists and engineers at Lawrenceville Plasma Physics have finally built an operational Dense Plasma Focus device. While still at less than half power, they were able to achieve a pinch on their device. The small company that Eric Lerner started recently gathered enough funding to start a two-year study on the validity of his theory regarding fusion-inducing plasmoids. If the theory holds, the device will produce more electricity than it consumes. In contrast to the billions of dollars spent on Tokamak fusion (think ITER), LPP is conducting their research on a budget around a million dollars. Yet, if it works, it will provide nuclear fusion with much simpler equipment and much less cost. Eric Lerner and Focus Fusion have been discussed on Slashdot before."

MIT Researchers Develop Autonomous Indoor Robocopter 69

An anonymous reader writes "Researchers at MIT's Robust Robotics Group have developed a robotic helicopter capable of autonomously flying inside buildings or other GPS-denied environments. It has an on-board camera and a laser scanner that maps the local environment. The video talks about search-and-rescue and civil engineering applications, but it also brings somewhat scary reminders of Minority Report to my head. How long till I see one of these chasing me down a dark alley? The team's website has more videos showing earlier stages of the project."

MS's "Lifeblogging" Camera Enters Mass Production 119

holy_calamity writes "Remember Microsoft's camera to be slung around the necks of people with Alzheimer's to help them recall where they'd been? A version of this device will now be mass-produced by a UK firm, Vicon, which obtained a license from Microsoft to manufacture the camera. It is worn around the neck and takes an image every thirty seconds, or in response to its light sensor, accelerometer, or body-heat sensor indicating that something of interest may be happening. Until now only a few hundred had been made for research, which showed they can genuinely help people with memory problems. The new version will be marketed to Alzheimer's researchers this winter, and to consumers for 'lifelogging' beginning in 2010."

California Moving Forward With Big-Screen TV Power Restrictions 339

Hugh Pickens writes "The Los Angeles Times reports that California regulators are poised to pass the nation's first ban on energy-hungry big-screen televisions just as they did with refrigerators, air conditioners and dozens of other products since the 1970s. 'We would not propose TV efficiency standards if we thought there was any evidence in the record that they will hurt the economy,' said Commissioner Julia Levin, who has been in charge of the two-year rule-making procedure. 'This will actually save consumers money and help the California economy grow and create new clean, sustainable jobs.' California's estimated 35 million TVs and related electronic devices account for about 10% of all household electricity consumption, but manufacturers quickly are coming up with new technologies that are making even 50-inch-screen models much more economical to operate. Sets with screens of up to 58 inches would have until the start of 2011 to comply with a minimum efficiency standard, with more stringent rules being introduced two years later. If all TVs met state standards, California could avoid the $600-million cost of building a natural-gas-fired power plant, says Ken Rider, a commission staff engineer. Switching to more-efficient TVs could have an estimated net benefit to the state of $8.1 billion, the commission staff reported."

German Team Wins 2009 Solar Decathlon 56

An anonymous reader writes "Our team recently competed in the 2009 US Department of Energy Solar Decathlon. The Solar Decathlon is a 2-year competition that challenges university students from 20 US and international teams to design, build, and operate the most attractive and energy-efficient solar-powered house. Objective scores are based on comfort control, appliance performance, net-metering, and home entertainment. Subjective contest scores are determined by juries that weigh the engineering design, architectural design, as well as marketing and communication strategies. Team Germany took 1st place due to a large net production of electricity, while Team California claimed top honors in the Architecture contest. Minnesota won the engineering design section. However, looking beyond the contest winners, the main purpose of the event is to raise awareness about solar technology and sustainable design. As part of this campaign, products used in all 20 homes are listed on the DOE website. The most exciting aspect is that the construction and engineering documents and communication materials from all teams are open-sourced for anyone to use or modify!"

HTC Dragging Feet On GPL Source Release For "Hero" Phone 181

Squiff writes to mention that despite being based on the Open Handset Alliance's Android platform and using several open source components, HTC are effectively refusing to release the source for the GPL parts of their "Hero" Phone code, saying that they are "waiting for their developers to provide it." It has been called an "object of lust," it's beating the iPhone for awards, and it seems to be the first Android phone that really is "the phone to have," to hear some people tell it. It has also just become available in the US after a June release in Europe.

Sonar Software Detects Laptop User Presence 167

Steve Tarzia writes "A research group at Northwestern University and University of Michigan has released open-source display power-management software that uses a new user presence detection technique. The goal is to shut off the display immediately when the user leaves the computer rather than using slow and error-prone mouse/keyboard activity timeouts. Surprisingly, the mic and speakers of many laptop computers are sensitive to ultrasonic frequencies. Those frequencies can be used to silently probe the laptop's physical environment. This software is based on research published at the UbiComp2009 conference. A Windows binary and source code for Windows and Linux are available for download."
