arcticstoat calls our attention to MIT research that has produced a version of polyethylene that can conduct heat away from computer chips. Polyethylene is the most widely used plastic. It's not clear how practical this research is for industrial-scale use, involving as it does an atomic-force microscope. The work is detailed in a paper published in Nature Nanotechnology this month. "The new process causes the polymer to conduct heat very efficiently in just one direction, unlike metals, which conduct equally well in all directions. ... The key to the transformation was getting all the polymer molecules to line up the same way, rather than forming a chaotic tangled mass, as they normally do. The team did that by slowly drawing a polyethylene fiber out of a solution, using the finely controllable cantilever of an atomic-force microscope, which they also used to measure the properties of the resulting fiber. This fiber was about 300 times more thermally conductive than normal polyethylene along the direction of the individual fibers, says the team’s leader..."

lilbridge writes "Huge reserves of "combustible ice" — frozen methane and water — have been discovered in the tundra of the Qinghai-Tibet Plateau in China. Estimates show that there is enough combustible ice to provide 90 years worth of energy for China. Burning the combustible ice may be a far better alternative than letting it just melt, releasing tons of methane into the air."

itwbennett writes "In a 45-minute press conference at the Game Developers Conference in San Francisco, Sony announced its motion controller, officially named the Playstation Move. The Move consists of the Eye Toy (a camera pointed at the player) and a wand-like controller with a lighted ball at the end and a range of buttons on the shaft, writes blogger Peter Smith. 'Alternatively games can use two of the wands, or one wand and one "sub-controller" that has an analog stick (the camera is always required),' says Smith. 'If this is sounding very much like the Wii's Remote and Nunchuk well, you aren't far off (though at least there's no cable between the two parts to smack you in the face when things get heated).' Here are Smith's thoughts on the demo: 'All in all, the demos seemed OK, but I, at least, wasn't really blown away by any of them. That said, it's always hard to tell how well these systems work without actually trying them for yourself. You need to feel the connection (or lack thereof) between what your hands are doing and what's going on on-screen in order to be sure. For example, in the boxing demo the player did a quick spin move that led to a roundhouse punch. It's hard to say if his motion triggered a pre-set action (a 'combo') or if the system was able to track the controller that accurately, and was able to 'connect the dots' from when his body briefly occluded the wand to when it reappeared.'"

Hugh Pickens writes "When the wind is blowing, it is usually the cheapest peaking power available. However utilities need consistent always-on power from large, cheap coal and nuclear power plants that are the backbone of the electric grid. Wired reports that operators are looking at Compressed Air Energy Storage (CAES) using abandoned mines and sandstones of the Midwest to store compressed-air. This converts the intermittent motions of the air into a steady power source by using it to run air compressors to pump air into an underground cave where it's stored under pressure. The first CAES plant in the United States actually went online in McIntosh, Alabama in 1991 where engineers created a geological pocket 900 feet long and up to 238 feet wide in a dome by pumping water into it to dissolve the rock salt. When the (briny) water was pumped back out, the salt resealed itself and they had an air-tight container."

alobar72 writes "I have quite a few old maps (several hundreds; 100+ years old, some are already damaged – so time is not on my side). What I want to do is to digitize them and to apply geo-coordinates to them so I can use them as overlays for openstreetmap data or such. Obviously I cannot put those maps onto my €80 scanner and go. Some of them are really large (1.5m x 1.5m roughly, I believe) and they need to be treated with great care because the paper is partly damaged. So firstly I need a method or service provider that can do the digitizing without damaging them. Secondly I need a hint what the best method is to apply geo coordinates to those maps then. The maps are old and landscape and places have changed, it maybe difficult to identify exact spots. So: are there any experiences or tips I could use?"

Barence writes "A debate that crops up time and again is whether it's better to have a dedicated keyboard on your smartphone or whether an on-screen keyboard with text correction is adequate. Some phones with screen-based keyboards have started to provide tactile feedback, either using an ultra-quick spin of their vibration alert or, like the BlackBerry Storm2, using clever piezo-electric technology to simulate the feel of a button press. But which system works best? PC Pro's Paul Ockendon gathered six of the most popular handsets around and put them through a timed typing test to see which proved quickest and most typo-free."

adeelarshad82 writes "After originally rejecting the story, online retailer NewEgg confirmed that a shipment of Core i7s were indeed fake, and apologized for the affair. NewEgg has also broken off its relationship with IPEX, the supplier of the phony lot. The retailer said that it has already contacted affected customers and would continue to reach out and replace the counterfeit parts. We discussed the fake Core i7s over the weekend."

chudnall notes a Technology Review story on a new gas engine injection system that promises increased efficiency of up to 50%. "The key is heating and pressurizing gasoline before injecting it into the combustion chamber, says Mike Rocke, Transonic's vice president of business development. This puts it into a supercritical state that allows for very fast and clean combustion, which in turn decreases the amount of fuel needed to propel a vehicle. The company also treats the gasoline with a catalyst that 'activates' it, partially oxidizing it to enhance combustion."

b4dc0d3r writes "How do you make sense of the various model numbers or naming schemes for CPUs, graphics cards, and the related chipsets? All I want is something that will run Oblivion and output full 1080 video to a TV. Last time I built my own computer I just went to Pricewatch, made a few easy choices, and everything came to my door. Do I really have to research the differences among Core i5, Core 2 Duo, Pentium 4, Pentium D, Sempron, Athlon, Phenom ...? And that's just the processor. Is there a reference somewhere? In short, how do you buy a computer these days?"

RABarnes writes "Scientific American has posted an article about the political efforts of natural gas and electric utilities to limit the growth of wind-generated electricity. Although several of the points raised by the utilities and carbon-based generators are valid, the basic driver behind their efforts is that wind-generation has now successfully penetrated the wholesale electricity market. Wind was okay until it became a meaningful competitor to the carbon dioxide-producing entities. Among the valid points raised by the carbon-based generators are concerns about how the cost of electricity transmission are allocated and how power quality can be improved (wind generation — from individual sites — is hopelessly variable). But there are fixes for all of the concerns raised by the carbon-based entities and in almost all cases they have been on the other side of the question in the past."

MojoKid writes "What could you do with 8 physical cores of CPU processing power? Intel's upcoming 8-core Nehalem-EX is launching later this month, according to Intel Xeon Platform Director Shannon Poulin. The announcement puts to rest rumors that the 8-core part might be delayed, and makes good on a promise Intel made last year when the chip maker said it would release the chip in the first half of 2010. To quickly recap, Nehalem-EX boasts an extensive feature-set, including up to 8 cores per processor, up to 16 threads per processor with Intel Hyper-threading, scalability up to eight sockets via Intel's serial Quick Path Interconnect and more with third-party node controllers, and 24MB of shared cache."

MikeChino writes "MIT scientists have discovered a never-before-known phenomenon wherein carbon nanotubes can be used to harness energy from 'thermopower waves.' To do this they coated the nanotubes with a reactive fuel and then lit one end, causing a fast-moving thermal wave to speed down the length of the tube. The heat from the fuel rises to a temperature of 3,000 kelvins, and can speed along the tube 10,000 times faster than the normal spread of this chemical reaction. The heat also pushes electrons down the tube, which creates a substantial electrical current. The system can output energy (in proportion to its weight) about 100x greater than an equivalent weight lithium-ion battery, and according to MIT the discovery 'opens up a new area of energy research, which is rare.'"

1sockchuck writes "What happens when the power goes out in one of Google's mighty data centers? The company has issued an incident report on a Feb. 24 outage for Google App Engine, which went offline when an entire data center lost power. The post-mortem outlines what went wrong and why, lessons learned and steps taken, which include additional training and documentation for staff and new datastore configurations for App Engine. Google is earning strong reviews for its openness, which is being hailed as an excellent model for industry outage reports. At the other end of the spectrum is Australian host Datacom, where executives are denying that a Melbourne data center experienced water damage during weekend flooding, forcing tech media to document the outage via photos, user stories and emails from the NOC."

jones_supa writes "Pixel Qi has just revealed their DIY kit for netbooks, planned to be out near the end of Q2 — sounds like June. This makes it possible to retrofit a screen to one fully readable in direct sunlight. In her blog, Mary Lou Jepsen says: 'It’s only slightly more difficult than changing a lightbulb: it’s basically 6 screws, pulling off a bezel, unconnecting the old screen and plugging this one in. That’s it. It’s a 5 minute operation.' She also talks about the 'laptop hospital,' a service depot started by kids in Africa."

An anonymous reader writes "When beginning to use keyboards I did not pay much attention to touch typing technique. Instead, I eventually achieved decent rates by simply doing what felt natural to me. These days my qwerty typing speed is in the range of 90-110 WPM, probably more toward the lower end. While this isn't too shabby, I feel some awkwardness in my technique (such as not using my little and ring fingers when I really should). Has anyone been in a similar situation, wanted to fix it, and actually done so? What do you reckon is the best way to fix half-broken typing? Touch training sessions? Should I switch to Dvorak and pretty much learn typing from scratch, but properly this time?"

Several readers have mentioned the strange goods that some customers received from Newegg in place of the Intel Core i7 920 processor they ordered. Word on the problem first surfaced on TribalWar on Thursday evening. Newegg still hasn't commented on this. It's not known whether it happened as a result fraud by another Newegg customer, in shipping, or where. The "processors" are made of aluminum, and the "fans" are some kind of synthetic molded material. The "factory seal" was printed onto the box; the holographic stickers on the boxes were also faked. The first part of this video shows the bogus goods. At this writing Google News lists a handful of blogs mentioning the fakes.

storagedude writes "This article discusses using solid state disks in enterprise storage networks. A couple of problems noted by the author: wear leveling can eat up most of a drive's bandwidth and make write performance no faster than a hard drive, and using SSDs with RAID controllers brings up its own set of problems. 'Even the highest-performance RAID controllers today cannot support the IOPS of just three of the fastest SSDs. I am not talking about a disk tray; I am talking about the whole RAID controller. If you want full performance of expensive SSDs, you need to take your $50,000 or $100,000 RAID controller and not overpopulate it with too many drives. In fact, most vendors today have between 16 and 60 drives in a disk tray and you cannot even populate a whole tray. Add to this that some RAID vendor's disk trays are only designed for the performance of disk drives and you might find that you need a disk tray per SSD drive at a huge cost.'"

astroengine writes "Mars has been visited by orbiters, landers and rovers, but could the future of Martian exploration be inspired by a wind-blown sphere? NASA and other research institutions have been developing the Mars Tumbleweed rover for the last decade, but with the help of the Planetary Science Institute, the Tumbleweed is now vying for some serious funding to further develop the technologies required. Although the Tumbleweed would be wholly dependent on the prevailing winds on the Martian surface, the lightweight and relatively cheap design could lead the way for a 'swarm' of independent Tumbleweeds to explore vast regions of the planet (video link). In 2003 and 2004, NASA even tested an inflatable Tumbleweed prototype on Greenland and Antarctica — it traversed hundreds of miles with ease, continually relaying location and environmental data."

Lanxon writes "The law that allows the US Internet Archive to collect and preserve websites does not apply to British archivists. In fact, experts from the Archive and many other archivist institutions argue that the only way the millions of Britain's websites could be legally archived is if British law itself was amended, reports Wired in an investigation published today. Currently, archivists have to seek permission from webmasters of every single site before they are able to take snapshots and retain data."
