900. GPS Robot Boats to Race Across Atlantic
Small ROBOTIC BOATS from all over the world are set to race each other next year across the Atlantic, some 4,000 miles from Brittany, France, to the Caribbean. The race, called Microtransat 2008, was conceived by a computer scientist at the University of Wales, Aberystwyth. Entry boats must be "fully autonomous" (they can use GPS), self-sufficient in terms of energy (via solar panels) and no longer than 13 feet.

2051. Whoops! Micro-Wind Turbines May Increase CO2
Installing electricity-generating home wind turbans -- also called "micro-wind turbines" -- is all the rage among yuppies who want the neighbors to know how eco-friendly they are. But now the UK's Building Research Establishment Trust says "turbines are likely to add to, not subtract from, a home's CARBON FOOTPRINT." The reason is that the turbines harm the environment in their construction and maintenance, a harm that can't be paid back in energy generation in urban areas.

2621. AMD delays Barcelona (again), turns attention to Brisbane
Filed under: Desktops, Laptops
Oh AMD, you just can't keep it together, can you? Advanced Micro Devices, a company known for its share of "issues," has once again delayed its much-hyped, energy efficient Barcelona CPU. Apparently, a technical irregularity has caused the company to push back the release date for widespread availability of the chip until sometime early next year. The glitch, which causes the chip to fail, is just another line of setbacks on the product's path to release (originally set for mid-2007). John Taylor, a company spokesman, says, "We're continuing to ship it but only to specific customers." The company is offering a workaround for the chips until the problems are solved, though users will see an impact on performance. In other heart-wrenching (though seemingly unrelated) AMD news, the chipmaker has decided to re-up its older K8 architecture, refocusing on "Brisbane"-based chips, and even adding a few new models to the line. Over the next two quarters, the company will release 11 new 65nm chips based on the older format, while just three new entries will be made in the "Phenom" -- or K10 -- line. Look, Hector, everyone is pulling for you (except maybe Intel) -- just get it together, man!

2636. Microsoft to test out Windows XP on OLPC XO
Filed under: Laptops
Don't fret, that feeling you've just been overcome with is nothing more than a harmless dose of déjà vu. Nearly a year ago to the day, we were hearing these same types of talks, and while the whole "XP on XO" conversation has been one of on-again / off-again nature, the switch has apparently been flipped to "go" once more. According to The Wall Street Journal, Microsoft is slated to test out Windows XP on OLPC XO laptops starting next month in the US, India and possibly Romania. James Utzschneider, general manager of Microsoft's Unlimited Potential Group, noted that it "wanted Windows to run on the XO and [that it was] investing significant energy and talent" to make sure it happened. Granted, Microsoft will have to be mighty pleased with the results before any of this goes commercial, as Mr. Utzschneider concluded by stating that the company "wants to [ensure] a quality experience before [making a] commitment to governments."

2668. Blast-Proof Fabric Resists Multiple Explosions
An anonymous reader tips a Gizmodo story on a fabric whose properties are counterintuitive, to say the least of it. "Zetix is a fabric so strong it will resist multiple car bomb blasts without breaking. It absorbs and disperses the energy from explosions... it can be used in body armor, window covering, military tents, and hurricane defenses... [and] it can be used as medical sutures that won't damage body tissue. All of this is thanks to a property that apparently defies the laws of physics: helical-auxetics, objects that actually get fatter the more you stretch them. The concept makes my head want to explode, but when you see it in action it actually makes sense."Read more of this story at Slashdot.

2942. Magellan Maestro 3100 hacked to add file manager / media player
Filed under: GPS
Although we've already seen Garmin's c510 / c530 get hacked up earlier this year, now it's time for Magellan's Maestro 3100 to head under the knife. The engineering David Goeken managed to personalize his unit with a custom splash screen, a beefed up POI file, a file manager for adding / sorting through applications and a full-fledged media player for good measure. Granted, there's a laundry list of known issues to go along with it, but hey, what fun is a hack without a little troubleshooting? Before hitting the read link and rolling up your sleeves, you may want to grab a meal and a few hours of rest -- you'll need the energy just reading through the how-to guide.

2984. IBM, others develop GreenCert greenhouse gas meter
Filed under: Misc. Gadgets
It's already developed a "gas gauge" for its servers, and a greener means of recycling silicon, but IBM now looks to be taking its increasing environmental awareness to an even larger scale, with it, Enterprise Information Management, and Evergreen Energy developing a greenhouse gas meter that promises to measure the carbon output of various industries and devices, according to IDG. Dubbed GreenCert, the software employs a whole mess of IBM tools including various WebSphere applications, along with an "engine" designed by the folks at C-Lock in order to take a snapshot of a particular company's carbon footprint. It then does it's thing again after the company's taken measures to reduce its carbon emissions, giving them proof of their reductions which they can use to get carbon emission credits that can be traded on the carbon market. The software won't be available in its final form until sometime in the first half of 2008, however, but those looking to get a jump on things can apparently get a beta version from C-Lock right now.

3085. Incandescent light bulbs be to shelved by 2012 in US
Filed under: Household
Better late than never, right? Regardless of your feelings on said mantra, the United States of America has finally passed a law barring stores from selling incandescent light bulbs after 2012. 'Course, the EU and Australia have already decided to ditch the inefficient devices in the not-too-distant future, but a new energy bill signed into law this week throws the US into the aforementioned group. Better grab a pack of the current bulbs while you still can -- soon you'll be holding a sliver of history.
