Comments: 67 +-   UAVs Go Green With Fuel-Cell Powered "Ion Tiger" on Sunday November 22, @01:23AM

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.'"

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."

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."

aaaaaaargh! writes "I'm using a laptop with Ubuntu 8.04 for work, a netbook with Ubuntu 9.10 when I'm outside, Mac OS X 10.5 for hobby projects, and Windows XP for gaming. For backups, I'm currently using Jungle Disk and Apple's Time Machine, and I use a local svn repository for my work data. Now I need to frequently exchange and synchronize OpenOffice and Latex files and source code in various cross-platform programming languages between one machine and another. Options range from putting everything online (but Jungle Disk disks seem to be too slow for anything else than backup), storing my data on external media like USB sticks or SD cards, or working with copies by synchronizing folders over the network. I don't want to give my data away to some server outside without strong encryption (controlled by me, including the source code) and external media like USB sticks are a bit too fragile according to my taste. The solution should be reliable, relatively failsafe, as simple as possible, and allow me to continue to use Jungle Disk for backup. So what would you recommend?"

Hugh Pickens writes "The advantages of RISC are well known — simplifying the CPU core by reducing the complexity of the instruction set allows faster speeds, more registers, and pipelining to provide the appearance of single-cycle execution. Al Williams writes in Dr Dobbs about taking RISC to its logical conclusion by designing a functional computer called One-Der with only a single simple instruction — a 32-bit Transfer Triggered Architecture (TTA) CPU that operates at roughly 10 MIPS. 'When I tell this story in person, people are usually squirming with the inevitable question: What's the one instruction?' writes Williams. 'It turns out there's several ways to construct a single instruction CPU, but the method I had stumbled on does everything via a move instruction (hence the name, "Transfer Triggered Architecture").' The CPU is implemented on a Field Programmable Gate Array (FPGA) device and the prototype works on a 'Spartan 3 Starter Board' with an XS3C1000 device available from Digilent that has the equivalent of about 1,000,000 logic gates, costing between $100 and $200. 'Applications that can benefit from custom instruction in hardware — things like digital signal processing, for example — are ideal for One-Der since you can implement parts of your algorithm in hardware and then easily integrate those parts with the CPU.'"

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.'"

DesScorp writes "Over the past few years, the City of Chicago has installed video cameras all over the city. Now the Wall Street Journal reports that the city has not only installed its own cameras for law enforcement purposes, but with the aid of IBM, has built a network that possibly links thousands of video surveillance cameras all over Chicago. Possibly, because the city refuses to confirm just how many cameras are in the network. Critics say that Chicago is becoming the city of Big Brother. 'The city links the 1,500 cameras that police have placed in trouble spots with thousands more—police won't say how many—that have been installed by other government agencies and the private sector in city buses, businesses, public schools, subway stations, housing projects and elsewhere. Even home owners can contribute camera feeds. Rajiv Shah, an adjunct professor at the University of Illinois at Chicago who has studied the issue, estimates that 15,000 cameras have been connected in what the city calls Operation Virtual Shield, its fiber-optic video-network loop.' There are so many camera feeds coming in that police and officials can't monitor them all, but when alerted to a situation, can zoom in on the area affected. The ACLU has requested a total number of video feeds and cameras, but as of yet, this information has not been supplied."

Announced at Supercomputing 2009 in Portland, Oregon, the 'modular Liquid-Immersion Cooled Server' technology wraps each server in a cool-bag-like device, which cools components inside a server, rather than cooling the whole data centre, or even a traditional 'hot aisle.'

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.'"

MojoKid writes "When Fusion-io's first ioDrive product hit the market, it was claimed to be a 'disruptive technology' by some industry analysts, with the potential to set the storage industry on its ear. Of course the first version of the ioDrive was an enterprise-class product that showed the significant potential of PCI Express direct-attached SSD storage, but its cost was such that the mainstream market couldn't possibly justify it, no matter what the upside performance looked like. Then we heard of Fusion-io's more consumer-targeted play, the ioXtreme, that was announced this past summer. Fusion-io has only very recently released these new, lower cost cards to market. The first-ever full performance review of the product over at HotHardware shows the half-height PCI Express X4 cards are capable of a robust 800MB/sec read bandwidth and about 300MB/sec of write bandwidth. The cards particularly excel versus a standard SSD at random read/write requests and even perform relatively well with small block transfers."

jtownatpunk.net writes "As time goes by, I find myself supporting a greater number of users moving through their 40s and into their 50s (and beyond!). I notice more and more of them are lowering the resolution of their displays in order to 'make it bigger.' That was fine in the CRT days, but, quite frankly, LCDs look like crap when they're not displaying their native resolution. My solution at home is to hook my computer up to a big, honkin' 1080p HDTV, but that's a bit of a political risk in an office environment. 'Why does Bill get a freakin' big screen TV?!' Plus, it's a waste to be paying for the extra inputs (component, s-video, composite), remote, tuner, etc. that will never be used. And a 37-47" display is a bit large for a desk. So here's my question: Is there a source for 24-27" monitors running at 1366x768 that are affordable and don't have all of the 'TV' stuff? Or is my only choice to just buy 27" HDTVs and admonish the users not to watch TV? (And, no, just giving them big CRTs is not an option. Most people would rather stare at a fuzzy LCD than 'go back' to a CRT.)"

For the 38th anniversary of Intel's groundbreaking 4004 microprocessor, the company is allowing us to release new details of their historic MCS-4 chip family announced on November 15, 1971. For the first time, the complete set of schematics and artwork for the 4001 ROM, 4002 RAM, 4003 I/O Expander, and 4004 Microprocessor is available to teachers, students, historians, and other non-commercial users. To their credit, the Intel Corporate Archives gave us access to the original 4004 schematics, along with the 4002, 4003, and 4004 mask proofs, but the rest of the schematics and the elusive 4001 masks were lost until just weeks ago when Lajos Kintli finished reverse-engineering the 4001 ROM from photomicrographs and improving the circuit-extraction software that helped him draw and verify the missing schematics. His interactive software can simulate an ensemble of 400x chips, and even lets you trace a wire or click on a transistor in the chip artwork window and see exactly where it is on the circuit diagram (and vice-versa)."

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."

An anonymous reader writes "Nearly 80 percent of security products fail to perform as intended when first tested and generally require two or more cycles of testing before achieving certification, according to a new ICSA Labs report that details lessons gleaned from testing thousands of security products over 20 years. Across seven product categories core product functionality accounted for 78 percent of initial test failures. For example, an anti-virus product failing to prevent infection and for firewalls or an IPS product not filtering malicious traffic. Rounding out the top three is the startling finding that 44 percent of security products had inherent security problems. Security testing issues range from vulnerabilities that compromise the confidentiality or integrity of the system to random behavior that affects product availability."

Cranberry said it is also working on producing a Blu-ray version of its 1,000-year disc."
