karvind writes "BBC reports that a student, Rosanna Kilfedder, from Brunel University has designed solar-powered handbag to make finding keys and other items at the bottom of a bag easier. The handbag, dubbed Sun Trap, uses a solar cell attached to the outside of the bag to trap energy from sunlight. The energy is stored in an internal battery which lights up the lining. The lining is made from an electroluminescent material and is lit up by the bag's zip which acts as a switch. The bag goes dark when the zip is closed or after 15 seconds if it is accidentally left open. A secondary use of the portable battery is as an emergency charger for mobile phones and other wireless devices."

Steve from Hexus writes "After a long wait, ATI's multi-GPU solution - CrossFire - is finally here. Hexus checks out Crossfire using an X850 Crossfire setup, which can be beaten in performance by a single GeForce 7800 GTX in some games. Too little too late, or will R520 based Crossfire prove more fruitful? Hexus also examines how Crossfire works, how easy it is to setup and what its limitations are with current hardware." Looks very interesting - I'd love to get one for review.

SteveK writes "Hexus has been testing some 34 PC power supplies to see which is best. There are some interesting results. An Enermax 535 Watt PSU couldn't deliver much over 450W, while a cheap 250W PSU did exactly what it said on the box. There's also a video of a (very cheap) 650W PSU under 400W of load, requiring over 1kW of input power to sustain the load, before blowing up."

They also include Editors' Top HDTV picks. For top flat-panel HDTV plasma: Panasonic TH-42PHD7UY." From their Ultimate TV Buying Guide: "Since the first HDTVs appeared in 1998, high-definition television has been on the mind of every TV buyer. The big question is whether now is the time to pay a few hundred to a few thousand dollars more and take the plunge on an HDTV set. We can't answer that question for you, but we can provide some basic information that may help you decide."

jobcello wrote to mention a BBC article discussing a new technique for power distribution that might provide electricity using a series of small "microgrids", in a manner similar to peer-to-peer software. From the article: "'This would save something like 20 to 30% of our emissions with hardly anyone knowing it ... A microgrid is a collection of small generators for a collection of users in close proximity ... It supplies heat through the household, but you already have cables in the ground, so it is easy to construct an electricity network. Then you create some sort of control network.' That network could be made into a smart grid using more sophisticated software and grid computing technologies."

photonic writes "The World Solar Challenge has just finished the first racing day. It is a 3000 kilometer race from Darwin to Adelaide for cars that are powered by solar energy only. The results from this day have not yet been published, but intermediate results suggest that the Dutch Nuon Solar Team is again on the lead. This team from Delft University of Technology has a reputation to uphold since they also won the previous two races in 2001 and 2003, the last one in a record breaking 97 km/h average. The Tesseract team from MIT was less fortunate: during the qualification they got off track and rolled over. After some fixing up they still managed to qualify into 7th place on battery power, but with substantial damage to the solar panel their challenge will be finishing rather than winning."

theodp writes "Citing millions of Japanese consumers as proof it can work, MIT's Philip Greenspun hasissued a call for comments on his hypothesis that the mobile phone can function as a home computer for a substantial number of consumers if it's paired up with an appliance that drives the phone from a full-size keyboard and display."

christchurch wrote to mention the story of a plucky Korean robot that has been built for combat. From the article: "According to design blueprints released during a meeting of science-related ministers, the robot will have six or eight extendable legs with wheels allowing it to move like an insect over uneven terrain. The robot will be armed with various weapons and will operate both by remote control and its own artificial intelligence system"

AugstWest asks: "As more research comes out showing that high voltage electricity sources can cause cancer and other health problems, I was wondering what the geeks among us could come up with for electrical shielding ideas. I've got a high-voltage transformer just off my backyard to power the train that also runs practically through my backyard, and it would be nice if I could somehow shield us from it. Of course, if the shield could also be an induction coil to sap power for my house, that wouldn't suck either..."

christchurch map writes "Jonathan Schwartz, president of server and software maker Sun Microsystems, said that the personal computer is increasingly becoming a relic. Instead, what has become important are Web services on the Internet and the majority of the world will first experience the Internet through their mobile phones." From the article: "Schwartz points to the increasing wealth and power of companies, like eBay, Google, Yahoo and Amazon.com, that profit from free services available over the network. Among his audience, many more people said they'd rather have access to Internet services than their desktop computing applications. And Microsoft--the company with the biggest financial stake in the PC software business--has struggled to cope with the arrival of Web services."

They have a Flash demo with Nabaztag's different messages. The company also makes 'La lampe Dal', a lamp that changes colors based on the weather and 'Le Pad Osmooze', a USB device that releases an aroma when you receive an email from a loved one."

DumbSwede writes "PhysOrg.com reports that according to calculations by B.M. Kuzhevsky, the head of the neutron research lab at Moscow State University, neutron levels far above normal background levels exist during lightning strikes. While only a small percentage of rainwater contains atoms of deuterium, the lightning still provides enough energy to create fusion events. Frequent Slashdot readers no doubt remember recent articles on Fusion induced by sonic compression and more recently by pyroelectric effect. Perhaps more controversially, and yet to be discussed on Slashdot, the NIF has possible plans for a hybrid fusion approach that uses not only deuterium and tritium, but uranium and plutonium as well in what amounts to a miniaturized version of how thermonuclear weapons achieve fusion. Fears are that this could lead directly to micro-H-bombs. This year has also seen the final selection of France for the ITER experimental Fusion Reactor site. With all the recent discoveries and developments in fusion research, my question for Slashdotters - are we on the verge of something big that will make fusion a practical reality in a much shorter time frame than the often quoted '30 years away, and always will be'?"

zygan wrote to mention a Fairfax Digital article about the possibility of a digital dark age, as a result of the increasingly short-term lifespan of digital storage. From the article: "It is 2045, he suggests, and his grandchildren are exploring the attic of his old house when they come across a CD-ROM and a letter, which explains that the disk contains a document that provides directions to obtaining the family fortune. The children are excited. 'But they've never seen a CD before - except in old movies - and, even if they found a suitable disk drive, how will they run the software necessary to interpret the information on the disk? How can they read my obsolete digital document?'"

A not-so anonymous Anonymous Coward puts forth this query: "As someone who tires of constantly remembering and re-entering many passwords in possibly hundreds of uses, it strikes me that something as simple as a USB memory-stick device containing security tokens cannot be simply used in favour of passwords. Kernel messages could be monitored for tokens and update local access as needed (such as opening kwallet or disabling the screensaver). Is this really any less secure than say, using a key in the front door? It would be great to hear what the Slashdot community have found useful in reducing the number of passwords that need to be remembered, and what progress (if any) is being taken to increase security while providing ease of access?"

An anonymous reader writes "So you have decided that you want an ITX system. Whether it's just to look cool or because you need to reclaim the desk space. Most people wouldn't know where to start when creating their system. Fear no more because XYZComputing.com has created a step by step process on how they created their system. Based on an MII10000 and using a USB Pen to load up Puppy Linux. No details are omitted so if you are new to Mini-ITX and do not have a clue what you need or where to start then this would certainly be a good place to start."

elrous0 writes "In spite of TiVo's continuing insistence that recent appearances of 'red flag' recordings are mere "glitches," the AP is reporting that customers are beginning to get nervous about the new content-blocking feature added in a recent TiVo upgrade. The story quotes Matt Haughey, of PVRblog.com, as saying 'TiVo would be of limited utility in the future if the studios were allowed to do this with regular broadcast content ... This is like cell-phone jammers. What if you couldn't talk on your cell phone? If customers can't do something with their TiVo that they could in the past, they will stop using it.'" We've touched on this topic in the past.
