ElectricSteve writes "Scientists at Cornell University report they can now use a light beam carrying a single milliwatt of power to move objects and even change the optical properties of silicon from opaque to transparent at the nanometric scale." As the article says, such an advancement "could prove very useful for the future of micro-electromechanical (MEMS) and micro-optomechanical (MOMS) systems."

Hugh Pickens writes "Increasingly, the military is deploying unmanned aerial vehicles, or UAVs, as eyes in the sky to scan the ground for targets and threats, especially for missions that are too dangerous for manned aircraft. Now Live Science reports that a new robotic spy plane called 'Ion Tiger' will harness alternative energy to make it more covert and longer lasting than battery-powered or engine-powered UAVs. A 550-watt, 0.75 horsepower hydrogen fuel cell will power the Ion Tiger with four times the efficiency of a comparable internal combustion engine and seven times the energy of the equivalent weight of batteries. When Ion Tiger took flight in October, it exceeded any demonstration of electrically powered flight so far, flying 23 hours and 17 minutes. 'And it carried a 5 lbs. payload to boot — enough to carry, say, a day-and-night camera,' says researcher Karen Swider-Lyons, head of the alternative energy section at the Naval Research Laboratory in Washington. 'No one has come close to flying 24 hours with a significant payload before.' Another big advantage is the Ion Tiger's reduced noise, heat and emissions. 'Think about lawnmowers or chainsaws — they're really loud,' says Swider-Lyons. 'It's hard to spy on people when they know you're there, so you had to fly them at high altitudes to keep them from being heard.'"

An anonymous reader writes "recombu.com has an article examining ten things mobile phones will make obsolete, including phone booths, wristwatches and handheld games consoles. It's interesting to see how many devices have been absorbed into mobile phone technology, and it raises the question: are we better off having everything in one device? The author poignantly concludes that while it's great to have so much power at our fingertips, it does mean that some of us will rely on mobile phones for even basic mental tasks, which is great until the battery runs out."

cheeks5965 writes "We've argued before over compressed air vehicles, a.k.a. air cars. Air cars are an enchanting idea, providing mobility with zero fuel consumption or environmental impacts. The NYTimes' Green Inc. blog reports that the reality is less rosy. New research from UC Berkeley and ICF International puts a period at the end of the discussion, showing that compressed air is a very poor fuel, storing less than 1% of the energy in gasoline; air cars won't get you far, with a range of just 29 miles in typical city driving; and despite appearing green the vehicles are worse for the environment, with twice the carbon footprint as gasoline vehicles, from producing the electricity used to compress the air. Given these barriers, manufacturer claims should definitely be taken with a grain of salt."

tburton writes "The US House of Representatives yesterday released the Conflict Minerals Trade Act (HR 4128) to try and end the international trade of tungsten, tantalum and col-tan, the mining of which is accused of fueling violent rape and murder in eastern Congo. Since the very same minerals power the most popular consumer electronics from HP, Verizon, Nokia, RIM and Intel, the Information Technology Industry Council has quickly signed a statement of support. Advocacy groups are hopeful these commitments prove to be meaningful as consumers begin to question the end result of the supply chains powering their favorite gadget."

Bourdain writes with news out of the University of Arkansas, where researchers are looking for ways to combat counterfeit RFID tags. Passive tags typically wait for a reader to transmit a signal of the appropriate strength and frequency before sending their own transmission. The scientists found that the amount of power required to trigger this varies quite a bit from one tag to the next, especially when many different frequencies are sampled. This and other physical characteristics give the tag its own "fingerprint" that is independent of the signal information stored in its memory, which the researchers say will facilitate the detection of cloned tags.

An anonymous reader writes "It's great that unelected bureaucrats in California are clamoring to save energy, but when they target your big-screen TVs for elimination, consumers and manufacturers are apt to declare war. CEDIA and the CEA are up in arms over this. Audioholics has an interesting response that involves setting the TVs in 'SCAM' mode to meet the energy criteria technically without having to add additional cost or increase costs to consumers. 'In this mode, the display brightness/contrast settings would be set a few clicks to the right of zero, audio would be disabled and backlighting would be set to minimum. The power consumption should be measured in this mode much like an A/V receiver power consumption is measured with one channel driven at full rated power and the other channels at 1/8th power.' This is an example of an impending train wreck of unintended consequences, and many are grabbing the popcorn and pulling up chairs to watch."

Lucas123 writes "Scientists at Intel are working on developing sensors that would be implanted in a person's head in order to harness brain waves that could then be used to control computers, televisions, cell phones and other electronic equipment. Intel has already used Functional Magnetic Resonance Imaging (FMRI) machines to determine that blood flow changes in specific areas of the brain based on what word or image someone is thinking of. People tend to show the same brain patterns for similar thoughts. 'Eventually people may be willing to be more committed ... to brain implants. Imagine being able to surf the Web with the power of your thoughts.' said Intel research scientist Dean Pomerleau."

Presto Vivace writes "Brian Krebs of the Washington Post reports on a study jointly released Tuesday by the Ontario Information and Privacy Commissioner and the Future of Privacy Forum. It seems that in the process of collecting all that feedback about energy use, utility companies will inevitably collect a great deal of information about us. From the article: 'Instead of measuring energy use at the end of each billing period, smart meters will provide this information at much shorter intervals, the report notes. Even if electricity use is not recorded minute by minute, or at the appliance level, information may be gleaned from ongoing monitoring of electricity consumption such as the approximate number of occupants, when they are present, as well as when they are awake or asleep. For many, this will resonate as a "sanctity of the home" issue, where such intimate details of daily life should not be accessible.'"

17-year-old Kevin Anderson has spent 200 hours cleaning up a park in Allentown, New Jersey in pursuit of his Eagle Scout badge. His blatant disregard for the brotherhood and collective bargaining power of the local Service Employees International Union however has not gone unnoticed. Union president Nick Balzano told the City Council that the union is considering filing a grievance against the city for allowing the scout to clear a 1,000' path at the park. "We'll be looking into the Cub Scout or Boy Scout who did the trails," Balzano said.

MojoKid writes "AMD launched yet another high-end graphics card based on their Radeon HD 5800 series technology, and this time it's a dual-GPU variant. Considering the fact that AMD's Radeon HD 5870 is currently the fastest single-GPU powered graphics card currently on the market, the new dual-GPU powered Radeon HD 5970 should offer performance that completely outclasses any other single graphics card on the market right now. The card has 3200 stream processors under the hood, though its graphics engines are built on 40nm manufacturing technology, so power consumption isn't actually too insane. The card does exceptionally well in the usual benchmarks, as expected." HotHardware has begun providing single-page views — a user-friendly decision. PCPer.com also has coverage. And pcpro.co.uk wonders whether, at 13" (33 cm) in length, the new card will even fit in most PC cases.

fahrbot-bot sends in a Register piece about DARPA issuing the penultimate contract for what is intended to be a jet-mounted laser cannon. The Reg outdoes itself in a BOTEC involving downsizing to shark scale. "The US military will shortly issue a brace of contracts for 'refrigerator sized' laser blaster cannons. One of the deals will see a full-power ground prototype built which will be the final stage prior to America's first raygun-equipped jet fighter. ... If it scales down far enough, this would seem to put handheld HELL-guns within an order of magnitude of the striking power offered by conventional small-arms. A 9mm pistol bullet has about 750 joules muzzle energy: a 5kg portable HELL-ray weapon would put out this much energy in a blast less than a second long. ... A dolphin can carry a human being weighing up to 100kg along for a ride. A thoroughbred shark in good training can surely match this. Thus, we seem to be looking at practicable head-[laser] output in the 20-kilowatt range."

MojoKid writes "NVIDIA is launching a new mainstream graphics card today, aimed at consumers in the market for a relatively low-cost upgrade from an integrated graphics solution or older entry-level GPU. The new GeForce GT 240 features a GPU with 96 processor cores, 8 ROP units, and 32 texture filtering units. The GPU is manufactured using a 40nm process, features a GDDR5 memory controller (that's also compatible with GDDR3), and unlike NVIDIA's current high-end GPUs, the GT 240 is DirectX 10.1 compatible. For $100 or less, what's perhaps most interesting is that this graphics card actually puts up respectable frame rates with AA turned on and no external power needed beyond what a standard PCIe slot provides."

eldavojohn writes "Uranium mines provide us with 40,000 tons of uranium each year. Sounds like that ought to be enough for anyone, but it comes up about 25,000 tons short of what we consume yearly in our nuclear power plants. The difference is made up by stockpiles, reprocessed fuel and re-enriched uranium — which should be completely used up by 2013. And the problem with just opening more uranium mines is that nobody really knows where to go for the next big uranium lode. Dr. Michael Dittmar has been warning us for some time about the coming shortage (PDF) and has recently uploaded a four-part comprehensive report on the future of nuclear energy and how socioeconomic change is exacerbating the effect this coming shortage will have on our power consumption. Although not quite on par with zombie apocalypse, Dr. Dittmar's final conclusions paint a dire picture, stating that options like large-scale commercial fission breeder reactors are not an option by 2013 and 'no matter how far into the future we may look, nuclear fusion as an energy source is even less probable than large-scale breeder reactors, for the accumulated knowledge on this subject is already sufficient to say that commercial fusion power will never become a reality.'"

supercomputing
CWmike writes "As amazing as today's supercomputing systems are, they remain primitive and current designs soak up too much power, space and money. And as big as they are today, supercomputers aren't big enough — a key topic for some of the estimated 11,000 people now gathering in Portland, Ore. for the 22nd annual supercomputing conference, SC09, will be the next performance goal: an exascale system. Today, supercomputers are well short of an exascale. The world's fastest system at Oak Ridge National Laboratory, according to the just released Top500 list, is a Cray XT5 system, which has 224,256 processing cores from six-core Opteron chips made by Advanced Micro Devices Inc. (AMD). The Jaguar is capable of a peak performance of 2.3 petaflops. But Jaguar's record is just a blip, a fleeting benchmark. The US Department of Energy has already begun holding workshops on building a system that's 1,000 times more powerful — an exascale system, said Buddy Bland, project director at the Oak Ridge Leadership Computing Facility that includes Jaguar. The exascale systems will be needed for high-resolution climate models, bio energy products and smart grid development as well as fusion energy design. The latter project is now under way in France: the International Thermonuclear Experimental Reactor, which the US is co-developing. They're expected to arrive in 2018 — in line with Moore's Law — which helps to explain the roughly 10-year development period. But the problems involved in reaching exaflop scale go well beyond Moore's Law."
