Charge Your Cellphone In 20 Seconds (Eventually) 295

Posted by timothy
from the drive-by-juicing dept.
New submitter GoJays writes "An 18-year-old from Saratoga, California has won an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds. The fast-charging device is a so-called supercapacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time. What's more, it can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries, according to the inventor Eesha Khare." This one in particular has been used so far only to power an LED, rather than a phone or laptop, but I hope in a few years near-instant charging of portable electronics will be the norm as supercapacitors grow more common.

Cell Phones As a Dirty Bomb Detection Network 101

Posted by timothy
from the solidarity-brother dept.
First time accepted submitter iinventstuff writes "The Idaho National Laboratory has built a dirty bomb detection network out of cell phones. Camera phones operate by detecting photons and storing them as a picture. The INL discovered that high energy photons from radiological sources distort the image in ways detectable through image processing. KSL TV reports that the INL's mobile app detects radiation sources and then reports positive 'hits' to a central server. Terrorists deploying a dirty bomb will inevitably pass by people carrying cell phones. By crowdsourcing cell phones, the INL has created a potentially very large, inexpensive, and randomly mobile radiation detection grid."

Patenting Open Source Software 60

Posted by Soulskill
from the system-and-method-for-protecting-innovation dept.
dp619 writes "The tactic of patenting open source software to guard against patent trolls and the weaponization of corporate patent portfolios is gaining momentum in the FOSS community. Organizations including the Open Innovation Network, Google and Red Hat have built defensive patent portfolios (the latter two are defending their product lines). This approach has limitations. Penn State law professor Clark Asay writes in an Outercurve Foundation blog examining the trend, 'Patenting FOSS may help in some cases, but the nature of FOSS development itself may mean that patenting some collaboratively developed inventions is inherently more difficult, if not impossible, in many others. Consequently, strategies for mitigating patent risk that rely on FOSS communities patenting their technologies include inherent limitations. It's not entirely clear how best to reform patent law in order to better reconcile it with alternative models of innovation. But in the meantime, FOSS still presents certain advantages that, while dimmed by the prospect of patent suits, remain significant.'"

Google Betting Its Google+ Systems Know What's Best For You 109

Nerval's Lobster writes "But at this year's Google I/O conference in San Francisco, Google announced that it has a plan to make Google Plus users more engaged, courtesy of new features backed by a handful of data-analytics tricks. Google Plus postings now feature Google-generated hashtags that, when clicked, direct the user to related content from across their network. From a backend-infrastructure perspective, that sort of thing leans heavily on Google's semantic analysis and the ability to make the right connections between various pieces of data. Google Plus will also automatically highlight certain photos out of dozens or even hundreds of shots. Say you went on vacation to India and took some photos of your significant other in front of the Taj Mahal; Google Plus will leverage its database of information to recognize that as a prominent landmark and pluck those photos out of the pile as 'special.' In the words of that posting on the Google+ Blog: 'Your darkroom is now a Google data center.' Are all these nifty, analytics-intensive features enough to change the larger fortunes of Google Plus? That's the big question. Google has a handsome-looking platform, one that performs certain activities with a high degree of polish and zip—but is that enough to counter Facebook?"

The problem is that if Bitcoin takes off, banks will still treat it like regular currency. Once you make a deposit, the bank will add it to a pool, and withdrawals will come from that pool. Your account holdings will still be a decimal formatted number in a database somewhere.

Not with Bitcoin. Sure, they could use a pool, but that wouldn't do them any good.

The reason for the pool is called Fractional reserve banking, and that's impossible to do with Bitcoin.

Microsoft's Most Profitable Mobile Operating System: Android 309

puddingebola writes "Steven J. Vaughan-Nichols has a piece of commentary discussing Microsoft's profit from their patent claims on Android. From the article, 'To some, Windows 8 is a marketplace failure. But its flop has been nothing compared to Microsoft's problems in getting anyone to use its Windows Phone operating systems. You don't need to worry about Microsoft's bottom line though. Thanks to its Android patent agreements, Microsoft may be making as much as $8 per Android device. This could give Microsoft as much as $3.4 billion in 2013 from Android sales.'"

New Zealand Set To Prohibit Software Patents 90

Drishmung writes "The New Zealand Commerce Minister Craig Foss today (9 May 2013) announced a significant change to the Patents Bill currently before parliament, replacing the earlier amendment with far clearer law and re-affirming that software really will be unpatentable in New Zealand. An article on the Institute of IT Professionals web site by IT Lawyer Guy Burgess looks at the the bill and what it means, with reference to the law in other parts of the world such as the USA, Europe and Britain (which is slightly different from the EU situation)."

English May Have Retained Words From an Ice Age Language 323

Posted by Unknown Lamer
from the grunt-grunt-statistics-grunt dept.
sciencehabit writes "If you've ever cringed when your parents said 'groovy,' you'll know that spoken language can have a brief shelf life. But frequently used words can persist for generations, even millennia, and similar sounds and meanings often turn up in very different languages. Now, a new statistical approach suggests that peoples from Alaska to Europe may share a linguistic forebear dating as far back as the end of the Ice Age, about 15,000 years ago. Indeed, some of the words we use today may not be so different than those spoken around campfires and receding glaciers."

Belgian Media Group Demanding Copyright Levy for Internet Access 162

from the mighty-morphing-copyright-rangers dept.
An anonymous reader writes with this tidbit from PC World about Sabam's latest demand for copyright levies: "Sabam, the Belgian association of authors, composers and publishers, has sued the country's three biggest ISPs, saying that they should be paying copyright levies for offering access to copyright protected materials online. Sabam wants the court to rule that Internet access providers Belgacom, Telenet and Voo should pay 3.4 percent of their turnover in copyright fees, because they profit from offering high speed Internet connections that give users easy access to copyright protected materials, the collecting organization said in a news release Tuesday." Sabam has previously demanded money from truckers for listening to the radio, and wanted to charge libraries royalties for reading to children.

Ask Slashdot: What If We Don't Run Out of Oil? 663

Posted by Soulskill
from the humvees-for-everyone dept.
symbolset writes "The Atlantic recently ran an in-depth article about energy resources. The premise is that there remain incalculable and little-understood carbon fuel assets which far outweigh all the fossil fuels ever discovered. The article lists them and discusses their potentials and consequences, both fiscal and environmental. 'The clash occurs when renewables are ready for prime time—and natural gas is still hanging around like an old and dirty but reliable car, still cheap to produce and use, after shale fracking is replaced globally by undersea mining of methane hydrate. Revamping the electrical grid from conventionals like coal and oil to accommodate unconventionals like natural gas and solar power will be enormously difficult, economically and technically.' Along these lines, yesterday the U.S. Geological Survey more than doubled their estimate of Bakken shale oil reserve in North Dakota and Montana to 7.4-11 billion barrels. Part of the push for renewables over the past few decades was the idea that old methods just weren't going to last. What happens to that push if fossil fuels remain plentiful?"

Physicists Attempting To Test 'Time Crystals' 231

ceview writes "This story at Wired seems to have lots of people a bit confused: 'In February 2012, the Nobel Prize-winning physicist Frank Wilczek decided to go public with a strange and, he worried, somewhat embarrassing idea. Impossible as it seemed, Wilczek had developed an apparent proof of "time crystals" — physical structures that move in a repeating pattern, like minute hands rounding clocks, without expending energy or ever winding down. ... [A] Berkeley-led team will attempt to build a time crystal by injecting 100 calcium ions into a small chamber surrounded by electrodes. The electric field generated by the electrodes will corral the ions in a "trap" 100 microns wide, or roughly the width of a human hair. The scientists must precisely calibrate the electrodes to smooth out the field. Because like charges repel, the ions will space themselves evenly around the outer edge of the trap, forming a crystalline ring.' The experimental set up is incredibly delicate (Bose Einstein Condensate), so it implies this perpetual motion effect can't really be used to extract energy. What is your take on it? It's unlike to upend anything, as the article suggests, because at a quantum level things behave weirdly at the best of times. The heavy details are available at the arXiv."

Quark! Quark! Beware the quantum duck!
