An anonymous reader writes to mention Nature is reporting that scientists have discovered a much more efficient way to use silicon to convert heat into electricity. This offers the possibility of many different applications including possibly charging your portable electronics just by wearing them close to your skin. "The concept of converting waste heat into electricity isn't exactly new, but it never really materialized due to efficiency hurdles. Now, scientists from the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley think they may have found a key [to] increase the conversion efficiency by a factor of 100."

An anonymous reader sends us to CNET UK's Crave blog, where they report on a demo from CES. So far the only uses for Cell chips have been research stuff and the PS3. Now Toshiba has put a Cell chip into a consumer laptop; they are calling it the Spurs Engine. "The system was demonstrated in modified Qosmio G45 laptops, each of which uses a standard Intel Core 2 Duo CPU in addition to a Cell chip with four 1.5GHz synergistic processing elements (SPEs). Toshiba had four demos running... Demo 3... scans all your movie files, recognizes faces, and creates thumbnails of those faces. You can then click the thumbnails to watch scenes with those faces in, or compile them in a separate playlist."

rambilly brings us a story from Wired about the origin and development of the iPhone. From the article: "Steve Jobs had tasked about 200 of Apple's top engineers with creating the iPhone. Yet here, in Apple's boardroom, it was clear that the prototype was still a disaster. It wasn't just buggy, it flat-out didn't work. The phone dropped calls constantly, the battery stopped charging before it was full, data and applications routinely became corrupted and unusable. The list of problems seemed endless. At the end of the demo, Jobs fixed the dozen or so people in the room with a level stare and said, 'We don't have a product yet.' The effect was even more terrifying than one of Jobs' trademark tantrums. When the Apple chief screamed at his staff, it was scary but familiar. This time, his relative calm was unnerving. 'It was one of the few times at Apple when I got a chill,' says someone who was in the meeting."

theodp writes "Mary Lou Jepsen, who left her One Laptop Per Child CTO gig on Dec. 31st, has reemerged with her sights set on a $75 laptop that will be designed by her new company, Pixel Qi, which is described as a 'spin-out' from OLPC. In a Groklaw interview, Jepsen calls for 'a $50-75 laptop in the next 2-3 years' and says it's time to go Crazy-Eddie on touchscreen prices as well." This is probably good news to Bruce Perens, who thinks that the recent report of Microsoft's dual-boot XO project (with Windows as well as the Linux-based Sugar OS) is a feint driven by Microsoft's fear of "the entire third world learning Linux as children." Update: 01/10 21:22 GMT by T : ChelleChelle adds a link to an excellent interview with Jepsen in the ACM Queue, in which she discusses OLPC and some of the technologies it contains.

apolloose noted Bruce Schneier's latest entry on Wired where he talks about insecured wifi networks, and suggests that you Steal this WiFi. Basically, since insecure WiFi is everywhere, why not? You're helping make the world a little better for someone else.

fermion writes "Wired asserts that the iPhone blew up the wireless industry. This article argues that because Apple demanded the opportunity to control their own phone, and ATT née Cingular agreed, other companies are opening up the networks, and Google now has the opportunity to make Android a reality. There are other tidbits. Allegedly Verizon turned Jobs down without even listening to his pitch, a decision they may well regret now that they are hemorrhaging customers. Also, that Motorola and the networks were responsible for the fiasco dubbed the ROKR, something which I believe given how damaged the American version of the RAZR was compared to international version. It also estimates that the iPhone cost upward of $150 million to design, and earns Apple about $200 profit per phone."

Ian Lamont writes "The OLPC Project and Microsoft are developing a dual-boot system to put both Linux and Windows on the laptops, according to an interview with Nicholas Negroponte. The article is thin on details, as the OLPC/Microsoft talks are apparently at an early stage. Could this be the end of the OS wars in Nigeria and other developing countries?" While Microsoft has been working on an OLPC-capable version of Windows for some time now, the interesting thing here is the dual-booting provision, rather than forcing users into an either-or choice.

Yogi_Stewart_4 writes "More OLPC/Intel love — apparently Intel used 'underhanded' tactics to try to block sales' contracts of the OLPC, trying to reach the customer directly after an agreement had been reached. "They would go in even after we had signed contracts and try to persuade government officials to scrap their contract and sign a contract with them instead. That's not a partnership." Mr Negroponte cited an example in Peru where Intel sales staff tried to persuade the country's vice-minister of education, Oscar Becerra Tresierra, to buy the Intel Classmate PC."

An anonymous reader writes "Mobile phones with built-in mini projectors will launch later this year, according to 3M, which gave PC Pro a hands-on demonstration of the technology at CES 2008. The projector has a brightness of around 8-10 lumens, and is capable of displaying an image of up to 50 in., although 3M's spokesperson Greg Roberts told us that, with perfect lighting conditions, it's possible to squeeze a 60-in. screen out of the projector."

nerdyH writes "A new Linux-based portable media player (PMP) features an eyeglass-like head-mounted display with 800 x 600 resolution. Dreamax's Indicube i-800 PMP provides an experience similar to sitting two meters away from a 54-inch screen, the vendor claims. It uses an 0.44-inch eMagin OLED display, claimed to offer the smallest pixel pitch in the industry."

bensafrickingenius writes "CNET's Crave site has an interesting article on Amazon's Kindle eBook reader, and the extensive reverse-engineering that fans of the device have accomplished. The site specifically points out the work of Igor Skochinsky at the Reversing Everything website. His work on the Kindle's Root Shell has revealed some fascinating goodies: 'Among the ones uncovered and described on his blog are a basic photo viewer, a minesweeper game, and most interesting, location technology that uses the Kindle's CDMA networking to pinpoint its position. There also are some basic location-based services that call up a Google Maps view to show where you are and nearby gas stations and restaurants.'"

alphadogg writes with a link to a NetworkWorld article about a troubling security scenario. Indiana University IT researchers are now saying that a WiFi attack intended to piggyback across unsecured access points could do serious damage in a city like Chicago or New York. By essentially brute-forcing the passwords on insecure routers, a worm-like firmware agent could be introduced to an estimated 20,000 networks in New York City alone. "Although the researchers did not develop any attack code that would be used to carry out this infection, they believe it would be possible to write code that guessed default passwords by first entering the default administrative passwords that shipped with the router, and then by trying a list of one million commonly used passwords, one after the other. They believe that 36% of passwords can be guessed using this technique."

SkinnyGuy writes "Mixed into all of PCMag's CES preview coverage is an interesting story about a projector that's no bigger than an iPod. An early version showed up at last year's CES, but some of the guts weren't inside the small body. Now they are. It uses lasers to project the image. Really fascinating, futuristic stuff."

theodp writes "The One Laptop Per Child project suffered a blow Monday, with CTO Mary Lou Jepsen quitting the nonprofit to start a for-profit company to commercialize technology she invented with OLPC (the first of Jepsen's pending OLPC patents was published by the USPTO on Dec. 13). The OLPC project halted consumer sales of the cheap laptop at the end of December."

An anonymous reader writes "The effects of mobile phone radiation on sleep were studied in Sweden in a laboratory experiment where subjects were exposed either to 884 MHz GSM radiation or placebo. The study finds that compared to placebo, in the radiation-exposed subjects there was a prolonged latency to reach the first cycle of deep sleep (stage 3). The amount of stage 4 sleep was also decreased. Moreover, participants that otherwise have no self-reported symptoms related to mobile phone use, appear to have more headaches during actual radiofrequency exposure as compared to sham exposure."

davidmwilliams writes "ASUS have released a cheap subnotebook. It is far from state-of-the-art tech-wise, with 512Mb RAM and a Celeron processor. It has a 4Gb hard drive and no optical drive. Its screen is 7" and runs at the odd resolution of 800x480 and the operating system looks like something Fisher Price might have designed. Why would you buy it? What on earth can you do with this?" I've been wondering this myself given the huge coverage in the media of this thing.

An anonymous reader writes "Gizmodo has gathered conclusive evidence which confirms that the iPhone Firmware 1.1.3 update is 100% real. It installs only from iTunes using the obligatory Apple private encryption key, which nobody has. The list of new features, like GPS-like triangulation positioning in Google Maps, has been confirmed too. Apparently it will be coming out next week, but there's bad news as expected: it breaks the unlocks, patches the previous vulnerabilities used by hackers and takes away all your third-party applications."

yali writes "The U.S. Transportation and Security Administration has issued new rules limiting travel with lithium batteries. As of January 1, no spare lithium batteries are allowed in checked luggage. Batteries carried in the cabin are subject to limitations on per-battery and total lithium content, and spare batteries must have the terminals covered. If you're returning home from the holidays with new toys, be sure to check out the new restrictions before you pack."

Lucas123 writes "Panasonic plans to unveil the thinnest Blu-ray Disc drive made yet at the upcoming CES show. The drive is 9.5mm high, which allows it to fit into standard laptop form factors instead of requiring manufacturers to redesign systems to fit high-def DVD players as they've been doing. 'Panasonic has already begun offering samples of the drives to laptop makers with the hope that the companies will build it into new PCs.'"

An anonymous reader writes "Apple is looking to patent a process that will save customers the hassle of waiting to order a cup of coffee at a local Starbucks. Even better: The technology would let you jump the line of those ordering in person. 'Customers might tap a button to order their favorite drink, say a double-shot mocha, as they stroll up to the nearest coffee shop. When the drink is ready go to, the device--such as an iPhone--would chime or blink to let the thirsty one know it's time to scoop up the order at the counter. The patent puts Apple's partnership with Starbucks in a new light. The technology promises to morph Apple from the business of simply selling gadgets and music and movies that can be played on those devices into an intermediary in all kinds of exchanges.'"
