Atom-thin water layers may lead to faster electric cars
So many battery breakthroughs focus on longer battery life (and for good reason), but what about the speed of delivering that energy? That's what North Carolina State University researchers want to solve. They've produced a material, crystalline tungsten oxide hydrate, that uses atom-thin water layers to tune electrical charge transfers for speed. When the team uses this material in a pseudocapacitor (which stores energy by transferring charges between electrodes and electrolytes), the result is a battery that theoretically represents the best of two worlds. It has the high energy density you'd expect, but it's also very quick at shuttling ions back and forth. That, in turn, could lead to performance breakthroughs in devices where rapid power is at least as important as raw capacity.
Intel wants to have conflict-free processors by the end of 2013
Intel had already promised that it would avoid using conflict minerals, and now it's giving itself a more concrete timetable for that to happen. It wants to have at least one processor that's proven completely conflict-free across four key minerals -- gold, tantalum, tin and tungsten -- by the end of 2013. Lest you think Intel's not taking swift enough action, it wants to reach the tantalum goal by the end of this year. The effort's part of a wider array of goals that should cut back on the energy use, power and water use by 2020. Sooner rather than later, though, you'll be buying a late-generation Haswell- or Broadwell-based PC knowing that the chip inside was made under nobler conditions.
Google makes 'next gen personal communications device,' is testing it in employee abodes
We first heard about Google's foray into home-based hardware late last week, when it asked the FCC for Special Temporary Authority (STA) to have employees test an "entertainment device" in their homes (as opposed to a lab). According to the New York Times and Wall Street Journal, it's rumored to be a Sonos-like device related to the Android@Home Tungsten hub we saw at Google I/O last year. It appears, however, that's not all Google's got in store, as some information has trickled out about another Google-branded gadget. Apparently, it's a "next generation personal communication device," and Mountain View has asked the FCC for another STA to test 102 of them in the same cities as the aforementioned entertainment box: Mountain View, LA, New York and Cambridge, Massachusetts.Why? Well, Google wants to track its Bluetooth performance and evaluate "the throughput and stability of the home WiFi networks that will support the device" in a real-world setting. Other details about the device are scant, but we do know that testing on this second Google-made gadget is ongoing through July 15th, so here's hoping we can get a glimpse of one between now and then. Check out the FCC docs for both devices at the source below, and feel free to sound off on what you think Google's got in store in the comments after.
Nokia establishes stance on conflict minerals in formal policy
Recent weeks have seen a swell of interest in corporate responsibility, particularly with regard to technology manufacturing and supply chains. Last month, Apple CEO Tim Cook affirmed his company's commitment to ethically and environmentally sound practices, evoking sentiments that were echoed today in a similar announcement from Nokia. Seizing the opportunity to establish some goodwill among socially conscious consumers, the Finnish manufacturer has just released a policy outlining its philosophy on conflict minerals -- metals like gold, tungsten and tin that have played a direct role in fueling civil violence and unrest in the Democratic Republic of Congo. In the document (linked below), Nokia acknowledged that it doesn't play a direct role in obtaining these materials, but emphasized its strict traceability requirements. All suppliers, Nokia says, must provide detailed information on the sourcing of its metals, going back to the smelter phase, at a minimum, and even to the mine itself, if necessary. The company also highlighted its adherence to guidelines established by the EICC-GeSI Extractives Work Group, which both Apple and Intel have already joined. Granted, it's impossible for a single company to wipe out civil strife and human rights abuses in one fell swoop, but with this codified approach, Nokia hopes to at least "increase transparency, ensure responsible procurement by our suppliers and sub-suppliers, and drive positive change."
Cyberdyne turns its HAL exoskeleton into an anti-radiation suit
The original Hybrid Assistive Limb (HAL) suit was designed to help those with muscle diseases, but it's now been upgraded to cope with a very different type of problem: handling radioactive substances. One of the few wearable materials that can stop radiation is tungsten, which is extremely heavy: a typical tungsten vest weigh up to 132 pounds. When worn in conjunction with a HAL exoskeleton, however, a vest can be worn for lengthy periods without causing fatigue -- potentially allowing greater access to hazardous sites like Fukushima.
Just say no: Apple and Intel stop using conflict minerals
While the US government hasn't issued an outright ban against the use of 'conflict minerals' coming from the Congo, it has passed a law that will require companies who use them to tell all of us when our gadgets have been paid for (in part) with blood. Looks like Apple and Intel weren't too keen on the bad PR that would come from such disclosures, and joined the Electronic Industry Citizenship Coalition and its Conflict-Free Smelter program. The program requires mineral processing plants either prove that they don't fund the ongoing hostilities in central Africa or peddle their war-supporting wares elsewhere. For now, that means that the folks in Cupertino and Santa Clara will have to find other sources for the three Ts (tungsten, tin, and tantalum) needed to sate our technological appetites.
Diamaze diamond-tipped razor blades can literally split hairs (video)
At last, a sign that we're advancing from our caveman heritage into a brave new world. Gone are the days of rough-hewn blades, the world of modernity does its cutting with "plasma-sharpened" implements polished off with a layer of synthetic, industrial-grade diamonds. Okay, we're not quite there yet, but we're en route, thanks to a small German outfit named GFD, which has recently debuted a diamond-tipped, tungsten carbide razor blade that promises to retain its sharpness 1,000 times as long as regular steel and to be precise enough to slice a human hair in half. Hell, that latter bit isn't even a promise, it's a fact, which you can verify in the video after the break. GFD is looking for a manufacturing partner to bring this ingenious prototype to market, and given its years of experience applying the technology to industrial uses, we reckon it has enough of a pedigree to stand a decent chance of success.
New law requires gadget companies to disclose 'conflict mineral' use
When President Obama put his pen to the Wall Street Reform and Consumer Protection Act last week, it wasn't just financial reform he signed into law, but also a stipulation that may affect your gadget purchases down the road. You see, at present your technology includes some amount of tantalum, tungsten and tin, three rare earths that happen to be mined heavily in the Congo... and thus indirectly linked to poverty, rape and death. The new US law won't stop that, and doesn't restrict any sort of trade -- it merely requires companies to disclose the use of such materials in independent audits filed with their annual financial reports. It does, however, allow companies that don't use bloody rocks to label their products "conflict-free," so we're sure astute marketing gurus are developing plenty of new all-plastic gizmos even as we speak. For the children, of course.
Snow Leopard takes a bite out of support for legacy Palm OS devices
Still rocking that Palm Zire with your new Intel-based Mac? Then you might just want to reconsider that upgrade to Snow Leopard, as Apple has apparently decided to ditch its support for legacy Palm OS devices in the latest incarnation of iSync. That, as you may be aware, had previously acted as a conduit for Palm's aging but still available Palm Desktop software, and let folks easily sync up their contacts and other data from their Centro, Treo, Zire, Tungsten, or even a venerable old PalmPilot. Of course, that doesn't quite rise to the same level of controversy as the whole Pre / iTunes situation, especially considering that Palm itself has mostly moved on from said devices, and there are still some third-party sync solutions available for folks that want to keep the Palm OS dream alive.
SDHC driver released for Palm OS devices
It looks like those still hanging onto a slightly aging Palm OS device now have a new option that'll let 'em breath a bit of new life into it, as one Dmitry Grinberg has released a driver that adds SDHC card support to a whole host of the devices. That includes the Tungsten T, C, E2, and T5, the LifeDrive, the Palm TX, and the Zire 31 and 72 -- support for other devices, including the Tungsten T3 and, yes, even the Tapwave Zodiac, is also promised. That boost in storage doesn't come free, however, but we're guessing there's at least a few Palm loyalists out there that'll gladly accept the $21 price tag to get a taste of what 32GB of storage is like.[Via TamsPalm]
