tjansen writes "Panasonic has announced plans to create 'home batteries.' They are lithium-ion batteries large enough to power a house for a week, making energy sources such as solar and wind power more feasible. Also, you can buy energy when it is cheapest, and don't need to worry about power outages anymore."

MikeChino writes "Sandia National Laboratories recently announced a new breed of glitter-sized solar cells made from crystalline silicon that use 100 times less material to generate the same amount of electricity as standard solar cells made from 6-inch square solar wafers. Perfect for soaking up the sun’s rays on unusual shapes and surfaces, the tiny solar cells are expected to be less expensive, more efficient, and have promising new applications in textiles, clothing, and building facade installations."

BuzzSkyline writes "Researchers in Belgium have developed devices to harvest the waste heat our bodies throw off in order to convert it to electricity to run devices such as a wristband blood oxygen sensor and an electrocardiogram shirt. As a side benefit, the power sources help cool you down and keep you looking cool, all while running sundry micropower devices. In fact, the researchers mention that the energy harvesting head band works so well that it can get uncomfortably cold. In that case, they say, 'This problem is solved in exactly the same way as someone solves it on the body level in cold weather: a headgear should be worn on top of the system to limit the heat flow and make it comfortable.' But it would be such a shame to cover up the golden heat-harvesting headband with a hat."

Hemos recommends the coverage over at Wired of a project to digitize nuclear reactor art. "Not all nuclear reactors are built alike. Power plant designs can vary in their fuels, coolants, and configurations, a fact beautifully illustrated by a series of reactor wall charts originally published in issues of Nuclear Engineering International during the 1970s and 1980s. Since then, the charts have been lovingly collected by Ronald Knief, a nuclear engineer at Sandia National Laboratory. Recently, he completed his collection... and began to digitize the drawings. The first eight out of more than 100 have now been permanently archived online... 'This is not a CAD/CAM-type thing,' Knief said. 'This really is art.'"

MojoKid writes "Intel has unveiled its next-generation Atom N450 processor, and a review of the new Asus Eee PC 1005PE netbook that houses it shows decent gains in performance and lower power consumption. The Atom N450 has been re-architected similar to Intel's other notebook processors in that it now has an integrated memory controller and graphics core on the CPU itself. In addition, Intel's serial DMI (Direct Media Interface) now replaces the system bus to the Southbridge IO controller. From a performance standpoint, the Atom N450 single core chip offers a nice performance gain versus previous generation Atom CPUs and it appears Intel has dual-core variants of the chip on the horizon as well."

uglyduckling writes "A grassroots Facebook campaign has pushed the 1990s Rage Against the Machine song 'Killing in the Name Of' to the top of the British music charts for Christmas. The campaign was planned to prevent the X-Factor winner from charting Christmas number one, as has been the case for the past four years. It was supposedly a kick against the commercialism of Christmas and commercial dominance in the music scene, although Rage and the X-Factor winner Joe McElderry were actually signed to the same label. Despite this minor detail, it's interesting to note that this is the first song to reach the number one spot through downloads alone in the UK, and is a testament to the organizational power of social networking sites like Facebook. The Facebook group also asked for donations to charity, and has raised £70,000 for the homeless charity Shelter."

loconet writes "This article in Gizmodo claims that Android's fragmented model is harming it, but Google has the power to save it. The rumored Google Phone could be a ploy to upset the wireless industry, or it could be an expensive niche device. Either way, it would be a bid to take Android back from the companies that seem hell-bent on destroying it. '...once handset manufacturers (and carriers, through handset manufacturers) have built their own version of Android, they've effectively taken it out of the development stream. Updating it is their responsibility, which they have to choose to uphold. Or not! Who cares? The phones are already sold."

Hugh Pickens writes "Nature reports that data collected on the timing of attacks and number of casualties from more than 54,000 events across nine insurgent wars, including those fought in Iraq between 2003 and 2008 and in Sierra Leone between 1994 and 2003, suggest that insurgencies have a common underlying pattern that may allow the timing of attacks and the number of casualties to be predicted. By plotting the distribution of the frequency and size of events, the team found that insurgent wars follow an approximate power law, in which the frequency of attacks decreases with increasing attack size to the power of 2.5. This means that for any insurgent war, an attack with 10 casualties is 316 times more likely to occur than one with 100 casualties (316 is 10 to the power of 2.5). 'We found that the way in which humans do insurgent wars — that is, the number of casualties and the timing of events — is universal,' says team leader Neil Johnson, a physicist at the University of Miami in Florida. 'This changes the way we think insurgency works.' To explain what was driving this common pattern, the researchers created a mathematical model which assumes that insurgent groups form and fragment when they sense danger, and strike in well-timed bursts to maximize their media exposure. Johnson is now working to predict how the insurgency in Afghanistan might respond to the influx of foreign troops recently announced by US President Barack Obama. 'We do observe a complicated pattern that has to do with the way humans do violence in some collective way,' adds Johnson."

DesScorp writes in to let us know about a White House piracy summit, which is going on this afternoon. Judging by the press accounts, the sort of intellectual property criminals they are interested in are large-scale DVD bootleggers, not individual downloaders. "Hollywood once again demonstrates its close ties to Washington DC, regardless of who is in power, with a White House summit on piracy to be attended by the top executives in Hollywood, as well as the music industry. Vice President Joe Biden will be leading the summit to discuss organized cooperation between the federal government and the entertainment industry on all matters of piracy. Also at the summit will be the Obama Administration's new Copyright Czar, Victoria Espinal. The summit comes after Congress has earmarked $30 million dollars of taxpayer funds for anti-piracy efforts." According to one attendee's tweet, the press was kicked out of the meeting around 20:45 GMT.

Hugh Pickens writes "BBC reports that Markus Haering's company had been working with the authorities in Basel, Switzerland to try to convert the heat in deep-seated rocks into electricity, but the project was suspended in 2006 when drilling triggered earthquakes, one of them with a magnitude of 3.4, leading Haering's company to pay out $9M in damages. Haering's team planned to drill a series of holes penetrating up to 3 miles (4.8 km) underground with water being pumped onto rocks with a temperature of more than 195C. Basel's location on top of a fault line – the upper Rhine trench – had been deliberately chosen because the heat was closer to the Earth's surface. A risk assessment has since shown that the prospect of further quakes is too high to continue drilling in the city. Haering faces up to five years in prison if the judge finds he intentionally damaged property. Haering has admitted the 3.4 magnitude earthquake was stronger than he had expected and that his team 'had very little knowledge of seismicity' before starting to drill, but called the quakes 'a learning process for everyone involved.' Despite Haering's trial, the Swiss appetite for geothermal projects has not diminished. Engineers are beginning preliminary drilling in Zurich to see whether that area was suitable for a similar scheme, and St. Gallen, in eastern Switzerland, plans to start work on its own geothermal project next year. Drilling efforts are being closely watched in the US, where the energy department is sponsoring more than 120 geothermal energy projects in several states."

klwood911 writes "What do you get when you combine a former Disney imagineer, Guitar Hero, a house and 21,268 Christmas Lights? Probably one of the coolest light displays you will see. Ric Turner turned his house into an interactive Guitar Hero Display. As he explains: 'Christmas Light Hero is using 7 light controllers from Light-O-Rama built from kits to control 21,268 lights and LEDs. Each controller has 16 outputs and 2-3 TTL level control inputs that are used by the game system to fire different programmed light sequences depending on what happens in the game. It relies on the fact that the game sequence is very consistent. If the game and the lighting sequences start together, they will stay in very good sync through the length of the song. The light program allows branching and overlays for fail, star power and "ready." I have some ideas to automate the initial show/game sync, but for now you have to push doorbell buttons at the right moments.'"

Barence writes "PC Pro's contributing editor Paul Ockendon has bought a new lawnmower powered by lithium-ion batteries — part of a recent flood of such lithium-ion-powered garden and workshop tools which are taking over from NiCd and NiMH thanks to lighter weight, longer life and lack of the pernicious 'memory effect.' This is pretty much the same battery technology used in laptops, mobile phones and MP3 players, so volume manufacture is already established. Yet laptop manufacturers charge more per Watt-hour than lawnmower makers. This blog investigates whether such a seemingly ludicrous situation can be justified."

bhagwad writes "The Delhi High Court has found Microsoft guilty of using money and influence to make it expensive to defend against piracy cases. According to the judge, 'When the constitution of India provides equality before law, this equality has to be all pervasive and cannot be allowed to be diluted because of money power or lobbying power.' Furthermore, the judge said that Microsoft had to deposit a certain amount of money beforehand, and, if they lost the case, the money would go to the defendants for their legal and travel expenses. For icing on the cake, the court also appointed a commissioner to probe the matter further and ordered Microsoft to pay the costs. In an age where muscled corporations harass the ordinary person through expensive litigation, it's highly pleasurable to see them rapped for it by a judge."

newscloud writes "Tech writer Glenn Fleishman compares the arguments against affordable, high speed, broadband Internet access in each home to arguments made against providing for common access to electricity in 1900 e.g. '...electric light is not a necessity for every member of the community. It is not the business of any one to see that I use electricity, or gas, or oil in my house, or even that I use any form of artificial light at all.' Says Fleishman, 'Electricity should go to people who had money, not hooked up willy-nilly to everyone ... Like electricity, the notion of whether broadband is an inherent right and necessity of every citizen is up for grabs in the US. Sweden and Finland have already answered the question: It's a birthright.'"

jangel writes "Stanford University researchers have demonstrated a way to turn ordinary paper into a battery, which may be crumpled or pressed into any form. It's said the technology promises greater durability, higher efficiency, and faster energy transfer than traditional batteries. The technique uses special ink made of carbon nanotubes and silver nanowires. Thanks to the small diameters of these materials, the ink sticks strongly to the fibrous paper, allowing the battery to be extremely durable. The paper battery could last through 40,000 charge-discharge cycles — at least an order of magnitude more than lithium batteries. According to the researchers, the paper batteries will be low-cost, may be crumpled or folded, and can even be soaked in acidic or basic solutions, yet their performance does not degrade. 'We just haven't tested what happens when you burn it,' one of the researchers quipped." This is the same Stanford research team, lead by Yi Cui, whose work with nanotechnology for battery applications we have discussed before. We've also delved into alternate routes to the holy grail of the ultra-thin battery.

MikeChino writes "Researchers at Arizona State University have genetically engineered cyanobacteria to dissolve from the inside out, making it easy to access the high-energy fats and biofuel byproducts located within. To do this they combined the bacteria's genes with genes from the bacteriaphage — a so-called 'mortal enemy' of bacteria that cause it to explode. Cyanobacteria have a higher yield potential than most biofuels currently being used, and this new strain eliminates the need for costly and energy intensive processing steps."

The upcoming issue of Nintendo Power revealed that Capcom is working on Mega Man 10 for a release via WiiWare sometime in the future. "Like Mega Man 9 (released for WiiWare in 2008), Mega Man 10 remains true to the series's roots with 8-bit-style graphics and sound, and tried-and-true Mega Man gameplay." According to the early look at Nintendo Power's article, the game may include an easier difficulty mode, likely inspired by complaints that the previous game was too hard. It also previews one of the new bosses, who is apparently called "Sheep Man." Make of that what you wool.

eldavojohn writes "Metrics can get really strange — especially on the scale of national consumption. Information consumption is one such area that has a lot of strange metrics to offer. A new report from the University of California, San Diego entitled 'How Much Information?' reveals that in 2008 your average American consumed 34 gigabytes per day. These values are entirely estimates of the flows of data delivered to consumers as bytes, words and hours of consumer information. From the executive summary: 'In 2008, Americans consumed information for about 1.3 trillion hours, an average of almost 12 hours per day. Consumption totaled 3.6 zettabytes and 10,845 trillion words, corresponding to 100,500 words and 34 gigabytes for an average person on an average day. A zettabyte is 10 to the 21st power bytes, a million million gigabytes. These estimates are from an analysis of more than 20 different sources of information, from very old (newspapers and books) to very new (portable computer games, satellite radio, and Internet video). Information at work is not included.' Has the flow and importance of information really become this prolific in our daily lives?"

twailgum writes "Twenty-two stories underground in Iron Mountain's Western Pennsylvania facility, 'you'll find Room 48, an experiment in data center energy efficiency. Open for just six months, the room is used by Iron Mountain to discover the best way to use geothermal conditions and engineering designs to establish the perfect environment for electronic documents. Room 48 is also being used to devise a geothermal-based environment that can be tapped to create efficient, low-cost data centers.'"

hduff writes "While lithium-ion batteries offer better performance than lead-acid or ni-cad batteries, the supply of lithium is limited and the batteries can pose problems. Researchers at the Technion-Israel Institute are building a better battery with easily obtainable sand and air."
