jakosc writes "The Economist has an interesting article about increasing the efficiency of wind-powered generators by turning them into flying wind farms. These tethered generators would harness high speed jet stream winds above 15,000 ft and in theory could give outputs of 40MW per generator (PDF). The developer's website has more details of some of the safety, technological, and economic issues."

max3000 asks: "I'm currently building an embedded device that will be used outdoors, and the technology is pretty much nailed down at this point, except the display. Quite honestly, I'm confused and lost in all the display technologies out there: LCD (TFT, passive/active, and so forth), ChLCD, OLED, FED, AMLCD, EL, electrophoretic, ePaper like eInk, and more (some of which may overlap). Can you help a confused, fellow reader? What I need is (apparently) fairly complicated: an outdoor, sunlight-readable (at-a-glance readable, not squint-your-eyes readable), VGA/SVGA display. The display should have a 4-6 inch diagonal, capable of displaying at least 16 color grayscale, and it should be based on a technology with a roadmap to color in 2-3 years time. If not driveable directly from a PC, the display should come with a development kit that is." What small displays are out there that can meet these specifications?

alphakappa asks: "I am interested in building a video wall as a personal project using recycled old laptops so that I can make use of the display controllers that are already present. Is there free or cheap software that can extend the display on Windows and still be capable of showing different videos on different zones (like, say run a video in one zone while showing a powerpoint presentation in another one) What tools would you use?"

iron-kurton wrote with a link to an AP story about a national initiative to scrap the internet and start over. You may remember our discussion last month about Stanford's Clean Slate Design project; this article details similar projects across the country, all with the federal government's blessing and all with the end goal of revamping our current networking system. From the article: "No longer constrained by slow connections and computer processors and high costs for storage, researchers say the time has come to rethink the Internet's underlying architecture, a move that could mean replacing networking equipment and rewriting software on computers to better channel future traffic over the existing pipes. Even Vinton Cerf, one of the Internet's founding fathers as co-developer of the key communications techniques, said the exercise was 'generally healthy' because the current technology 'does not satisfy all needs.'"

1sockchuck writes "Just days after Google announced that it may build a huge data center in the state, Oklahoma's governor has signed a bill into law that will effectively exempt the largest customers of municipal power companies from public disclosure of how much power they are using. Officials of the state's power industry say the measure is not a 'Google Law' but was sought 'on behalf of large-volume electric users that might be considering a move to Oklahoma.' Others acknowledge that data center operators were among those seeking the law, apparently arguing that the details of their enormous power usage are a trade secret. Google recently acquired 800 acres in Pryor, Oklahoma for possible development as a data center, and is reportedly seeking up to 15 megawatts of power for the facility."

newtronic clues us to an article in IEEE Spectrum by Jeff Hawkins (founder of Palm Computing), titled Why can't a computer be more like a brain? Hawkins brings us up to date with his latest endeavor, Numenta. He covers progress since his book On Intelligence and gives details on Hierarchical Temporal Memory (HTM), which is a platform for simulating neocortical activity. Programming HTMs is different — you essentially feed them sensory data. Numenta has created a framework and tools, free in a "research release," that allow anyone to build and program HTMs.

audiophile writes "Just because it's a PC doesn't mean it can't output good-sounding audio. In the same vein as specialty A/V products, you can find PC-based A/V systems with extensive audio processing and step-up performance specifications, including Signal-to-Noise ratio, which can make a significant difference when using the analog outputs. Media center manufacturer Niveus shares tips for getting high-quality audio from a PC."

Martin_Sturm writes "A $175 1GB USB stick designed to protect your data turns out to be a very insecure. According to the distributer of the Secustick, the safety of the data is ensured: 'Due to its unique technology it has the ability to destroy itself once an incorrect password is entered.' The Secustick is used by various European governments and organizations to secure data on USB sticks. Tweakers.net shows how easy it is to break the protection of the stick. Quoting: 'It should be clear that the stick's security is quite useless: a simple program can be used to fool the Secustick into sending its unlock command without knowing the password. Besides, the password.exe application can be adapted so that it accepts arbitrary passwords.' The manufacturer got the message and took the Secustick website offline. The site give a message (translated from Dutch): 'Dear visitor, this site is currently unavailable due to security issues of the Secustick. We are currently working on an improved version of the Secustick.'"

LEGO - my - Crackberry writes "Matthias Wandel is an engineer at Research in Motion (RIMM), the company that makes the Blackberry. What did RIMM turn to for testing the antenna reception of one of its 900MHz devices? LEGO machines. Specifically a device made of LEGO that could rotate a Blackberry about its horizontal & vertical axis in a pre-defined pattern."

GoSun wrote in with an article about new solar panels that opens, "Sunlight has never really caught fire as a power source, mostly because generating electricity with solar cells is more expensive and less efficient than some conventional sources. But a new solar panel unveiled this month by the Georgia Tech Research Institute hopes to brighten the future of the energy source." The new panels are able to produce sixty times the current of traditional models.

stacybro writes "There is an article on Wired about the Top 10 most influential Amiga games. As someone who actually programmed on the Amiga way back when, I can attest to how far they were ahead of the clones when it came to graphics and audio hardware. I often wonder where the PC world would be if Amiga or Apple had had the marketing smarts (or maybe it was cut throat attitude) of Microsoft. 'Defender of the Crown (Cinemaware, 1986): Way before the Hollywood-ization of the game industry, Cinemaware evoked the era of classic movies with this game and others, such as Wings and the classic B-movie tribute It Came From the Desert. Cinemaware titles were definitely precursors of the CD-ROM era of flashy titles such as Myst and The 7th Guest. More importantly, they brought strong and realistic characterization and depiction to the world of computer games. Cinemaware is still alive today and currently working on an update of Defender of the Crown.'"

Lucas123 writes "There's a really good, detailed review at the Computerworld site on the top four external hard drives with more than 500GB of capacity. The story reveals some big flaws in the external drives, like malfunctioning one-touch backup buttons, USB 2.0 ports that don't recognize the drives, and drives coming out of the boxes unformatted. It's also an eye opener with regard to actual backup speeds. 'Broadband connections, peer-to-peer networks and larger media files coupled with new regulations that require diligence in backing up files have clearly affected the external hard drive market as drive capacities expand to 1TB and beyond. Meanwhile, the prices of those drives continue to drop, making them ever more attractive, particularly with the ease of deployment -- literally a two-minute installation, and you're ready to go. We put four of the leading external hard drives to the test. Our criteria were simple: The drives had to have multiple connection technologies (USB 2.0 plus FireWire 400 or FireWire 800 or both), include backup software and have a capacity of at least 500GB.'"

David Kesmodel from WSJ writes to let us know about an IBM breakthrough: a practical three-dimensional semiconductor chip that can be stacked on top of another electronic device in a vertical configuration. Chip makers have worked for years to develop ways to connect one type of chip to another vertically to reduce size and power use. The IBM technique of "through-silicon vias" offers a thousand-fold reduction in connector length and a hundred-fold increase in connector density. The new chips may appear in cellphones and other communication devices as soon as next year. PhysOrg has more details.

An anonymous reader asks: "I was recently doing a closet-cleaning and came across literally hundreds of old software CDs that are no longer usable — both manufactured CDs and CD-Rs. Note that by 'not usable', I mean that many of them simply couldn't be read anymore, possibly due to the fact that they'd been stored rather ineptly (no, I wasn't responsible for how they were stored). It seems wrong to just throw them out, but are there other things that can be done with them that will allow their raw materials to be reused in some way?Is it possible to reclaim CDs for raw materials?"

An anonymous reader writes "A robotics hobbyist has created what he claims is the world's smallest autonomous robot. The robot is half the volume of the robots produced by Sandia National Labs in 2001, moves quite a bit faster, and was made using techniques and supplies accessible to anyone." While Sandia Labs has had some time to improve on their original designs, it's still pretty cool to see what one can do at home as well.

LED lover writes "The discovery of the LED is usually credited to four US groups in 1962, but an unrecognized Russian genius got there forty years before. Oleg Losev even filed a patent on using his device for long range communications, and wrote to Einstein to ask for help with the theory — but got no reply."

Researchers at Georgia Institute of Technology have created a working prototype nanogenerator capable of generating as much as 4 watts per cubic centimeter of continuous direct current. The generators are green (to use), drawing power from natural motion in the surrounding environment. They are based on non-toxic chemicals and should be safe for use in biomechanical implants, but that's not their only potential use. From the article: "If you had a device like this in your shoes when you walked, you would be able to generate your own small current to power small electronics," Wang noted. "Anything that makes the nanowires move within the generator can be used for generating power. Very little force is required to move them."

Anonymous Howard writes "Toshiba and Matsushita, in a joint venture, are going to be bringing OLED TV panels to market within 3 years! Granted, the size of the panel is only 20.8 inches, but that is a huge step up from the small OLED screens used in cell phones and other portable devices. It will have a resolution of 1,280 by 768 pixels (WXGA) and handles 16.7 million colors. No specifications on contrast, brightness, or refresh rates have been released, but such specs wouldn't necessarily be indicative of OLED displays to be released in three years' time."

jetkins writes "The Melbourne Age reports that company officials announced Tuesday that Palm will move to a new Linux-based platform 'to help the company compete better.' The move was announced 'during a meeting with analysts in New York, where they also discussed the company's business strategy and refused to talk about recent rumors of a possible buyout.'"
