Sony working on phone batteries that last 40 percent longer
Recent history has taught us we can't expect our smartphones to last more than a day on a single charge. Bigger batteries are an uninspired solution and fast-charging a minor consolation, so it's no wonder researchers and companies alike are trying to develop new, more efficient battery tech. As Nikkei reports, Sony's in the same boat, working on new types of batteries that could carry 40 percent more energy than lithium-ion counterparts (fun fact: Sony developed the first commercial Li-ion battery).
Spotted at IDF: NEC's lightweight LaVie Z Ultrabook (hands-on video)
Remember NEC's LaVie Z Ultrabook we first heard about at Computex? It's a super light (875g / 1.93 lbs) and thin (15mm / 0.59-inch) magnesium alloy system running Windows 7 that's only available in Japan and we just spotted it here at IDF 2012 in San Francisco. Spec-wise you're looking at a 1.9GHz third-generation (Ivy Bridge) Core i7 CPU, 4GB RAM, 128GB SSD with integrated Intel HD 4000 GPU driving a 13.3-inch 1600 x 900-pixel display. It features an SD card slot on the left side, audio, USB 2.0, USB 3.0, HDMI and power connectors on the right edge along with the obligatory webcam. We spent a few minutes using the LaVie Z and were quite impressed with how lightweight and well made it is. It feels like a premium Ultrabook yet still looks unique -- unlike the plethora of me-too designs the PC industry's been dumping on the market lately (yes, we're looking at you, HP). The screen is nice and bright with decent viewing angles. NEC's done a good job with the button-less trackpad which is properly responsive. Sadly the keyboard is a bit of a mixed bag -- the short travel and small surface area of the individual keys will be an issue for some. Want to know more?

Green House's lantern runs on salt and water, powers your gadgets via USB
Japanese company Green House Co Ltd has quite an eclectic product portfolio, what with its women-only camcorder and peripherals like a PCI Express interface card with USB 3.0 support. Its latest device falls under another category entirely: the rivetingly named GH-LED10WBW is an LED lantern that runs on just water and salt; no batteries required. The light source provides eight hours of electricity per dose of saline water, and the lantern comes with a dedicated water bag for mixing the solution. The salt / water combo acts as an electrolyte with the magnesium (negative electrode) and carbon (positive electrode) rods inside the lantern. Users can get about 120 hours of power with the Mg rod before they'll need to buy a replacement (the rod is sold separately to begin with). More than just supplying a battery-free source of light, though, the lantern can function as a charger, thanks to a USB port built into the casing. Pricing has yet to be announced, but the GH-LED10WBW will be available by mid-September.
NEC's LaVie Z Ultrabook has definitely lost weight: just 875 grams and priced from $1,600 in Japan
No one complained when we reported NEC's initial claimed weight of 999 grams (2.2 pounds) for its LaVie Z Ultrabook, but it turns out that statistic is brutally unfair. The 13.3-inch laptop actually tips the scales at just 875 grams (1.9 pounds) thanks to the magnesium lithium alloy used in its 0.59-inch chassis -- not bad when you consider that there are still 1.3kg netbooks wandering the planet. Of course, in line with Intel's official Ultrabook spec, you're getting a minimum Core i5-3317U processor (yes, that's Ivy Bridge) and 128GB SSD, plus USB 3.0, SDXC slot, HDMI out and a claimed battery life of 8.1 hours. There's no word on US pricing yet, but that base spec will set you back ¥130,000 ($1,600) in Japan, while the top model with Core i7-3517U and 256GB SSD will add another ¥30,000 ($375) to your bill.
NEC's 13.3-inch LaVie Z Ultrabook weighs just 2.2 pounds, brings lithium-magnesium into your life
Just in case you thought NEC was done with its PC updates this week, the Japanese PC builder has thrown its hat into the Ultrabook ring with a unique contribution of its own. The LaVie Z has a 13.3-inch screen like your garden variety ultralight, but it weighs just 2.2 pounds through a new lithium-magnesium alloy shell about half the weight of the aluminum that some companies love to use. Unfortunately, that weight and the slim frame are about all we know so far: NEC isn't providing any internal specifications, possibly because it's waiting on Ultrabook-ready Ivy Bridge chips. Even so, if you're hanging around Japan and want the lightest possible laptop you can get at a 13-inch screen size, the wait until the planned summer release will feel like an eternity.
Dry ice makes graphene cheaper, greener, and by the (relative) boatload
Dry ice isn't just great for keeping steaks cold and filling your bathtub with fog, it may also play a major role in producing the miracle metal material graphene. Researchers at Northern Illinois University have discovered that burning magnesium in frozen carbon dioxide produces a thin layer of the hyped-to-the-lattices carbon nanostructure. The so-called dry-ice method has several advantages over previous techniques, not the least of which is the ability to pump out the relative of pencil lead on a much larger scale. It also happens to be faster, cheaper, and more environmentally friendly compared with the lengthy processes involving hazardous chemicals used in most graphene production. It's pretty great news but, honestly, all we want to know is when the stuff is going to start powering super-fast internet connections -- that complete Flying Circus collection isn't going to download itself.
iFixit tears down Galaxy S 4G, lights a fire for science
iFixit's teardown of the Samsung Galaxy S 4G doesn't exactly contain a ton of surprises -- until the very end, that is. Apparently, there's been some talk that Samsung used magnesium instead of aluminum for some of the components, and the best way iFixit could find to test that was to file some dust off the frame and set it ablaze (magnesium's reaction is noticeably different than aluminum). Spoiler alert: it's magnesium. Hit up the link below for the full blow-by-blow account.
Dell Latitude XT3 convertible tablet, hands-on (video)
Dell unveiled a mighty business laptop lineup this morning, but only a few stood out -- like this Dell Latitude XT3 convertible tablet PC with a quad dual-core Intel Sandy Bridge processor inside. Yes, it seems Dell's decided to forgo the incredible battery life of its predecessor for potent performance instead, with this particular unit packing a 2.5GHz Core i5-2520M CPU and 2GB of RAM underneath that swiveling 13-inch display. While the prototype XT3's screen seemed a little washed-out and viewing angles left something to be desired, we have to admire its matte dual-digitizer display, which takes multitouch input from at least three fingers simultaneously and also recognizes a pop-out stylus pen (the former responsive enough to navigate Windows 7 by touch alone, and the latter beyond our can't-draw-a-straight-stick-figure ability to easily test). That sunlight-readable screen isn't just for traveling artists, though, as Dell was quick to inform us that the XT3 is the company's attempt to make a convertible tablet that corporate IT will accept as one of its own, thanks to the same magnesium frame and universal docking port as the rest of the new Latitude lineup. We can't lie: we'd be pretty excited about the potential for awesome here, if we had any notion of release dates or price. Find some pictures below, and mosey past the break for a hands-on video. %Gallery-115994% Myriam Joire contributed to this report.
Toyota working on magnesium batteries for PHEVs of the not so near future
Toyota wants to take your range anxiety out for a walk behind the woodshed and obliterate it from the known world. The means for doing this, the Japanese giant has revealed, might very well be contained in its new magnesium-sulfur batteries, which promise to double the energy density of the current industry-best lithium ion cells. Of course, the catch here is that the new magnesium goodness is nowhere near ready and is projected to come in 2020 at the earliest, but we're gladdened to see a long-term view being taken by car manufacturers with regard to powering vehicles electrically. Alternative methodologies currently under review in Toyota's labs also include aluminum and calcium materials, showing that there is indeed no lack of ambition for making plug-ins respectable road warriors.
Engineuity developing hydrogen-creating, emission free vehicle
Just in case there weren't enough alternate fuel developments going on around the world, it looks like we've got yet another vying for business over in Israel. Engineuity, a company started by Amnon Yogev, has reportedly developed a method for vehicles to "produce their own fuel" using metals such as magnesium and aluminum to create hydrogen and steam. Similar to a solar-powered "zinc-to-hydrogen" approach that gained attention in 2005, this method utilizes a "long metal coil" which would be inserted into a metal-steam combustor that stands to "separate hydrogen out of heated water." After intense heating, the metal atoms would purportedly bond to the oxygen from the water, creating metal oxide; the result would free up hydrogen molecules to be sent to the engine alongside the steam to provide the juice. The firm also insinuates that "refueling" the vehicle would be "remarkably simply," and construction could be completed on current production lines without requiring entirely new infrastructures. According to Yogev, the "running cost of the system should be equal to that of conventional cars today," and hopes to have a full scale prototype ready to rumble in "around three years."[Thanks, Mike]
