US mineral companies to tech industry: drill, baby, drill
Even if your favorite gadget isn’t flaunting them, rare earth metals are vital to all sorts of high-tech gizmos, from your flat-panel TV and computer hard drive to the hefty batteries that power the Toyota Prius. But over 95% of the world’s rare earth comes from China; and late last year, China told the world that they’d like to keep the lion’s share all to themselves. What will we Westerners do? Well, we could let China continue producing mountains of e-waste on our behalf. But we could also find plenty of rare earth just by digging in our own backyard. According to the U.S. Geological Survey, the United States has over 13 million metric tons of rare earth with concentrated deposits in Mountain Pass, California and Diamond Creek, Idaho. But since the private firms that control those deposits aren’t willing to spend the requisite eight years and minimum $500 million to construct a chemical separation plant, Idaho-based U.S. Rare Earths is just sitting on their ore for now, while California’s Molycorp Minerals is forced to send their material all the way to China (once again) for processing.
“No one wants to be first to jump into the market because of the cost of building a separation plant,” former USGS rare earth specialist Jim Hedrick told LiveScience. Should China’s export dwindle and the U.S. feel the pinch, that may change, but for now it’s good to know that when the global game of StarCraft tells us “not enough minerals,” we’ll know exactly where to look.

Microsoft says Windows 7 battery ‘issue’ isn’t one
After Microsoft stated a week ago that it would look into reports of Windows 7 causing premature battery degradation, we’ve been staying up late at night with our frazzled lithium ion cells, reading them stories about Battery Heaven and generally trying to keep an upbeat tone around the Engadget HQ. Well, it turns out not everything is rosy in batteryville, but Microsoft says Windows 7 isn’t the one to blame. According to the company’s testing, the new tool, which reports when a battery is down to 40% of its designed capacity and suggests replacement, hasn’t reported a single false positive. Additionally, the tool uses read-only data from the battery, and is in fact incapable of tweaking the battery’s life span or internal data — it merely reports the data it receives, and stacks the theoretical design capacity up against the current full charge capacity. Microsoft attributes the reports of the tool dooming batteries to an early grave to the mere fact that many people might not have noticed the degradation already taking place in their batteries — most batteries start to degrade noticeably within a year. Of course, not everybody’s going to just take Microsoft’s word for it, and Microsoft itself will continue to look into the issue, but for now this sounds like a bit of a non-issue. The part about Windows 7 being less conservative with power use is a whole ‘nother issue, of course.

Quantum batteries are theoretically awesome, practically non-existent
Today’s dose of overly ambitious tech research comes from the physics lab over at the University of Illinois at Urbana-Champaign, in a proposal titled “Digital quantum batteries: Energy and information storage in nano vacuum tube arrays.” It’s like a who’s who of undelivered promises got together and united to form one giant and impossible dream, but it’s one we’d prefer to believe in regardless. Aiming to improve battery performance by “orders of magnitude,” the project’s fundamental premise is that when capacitors — and we’re talking billions of them — are taken to a small enough scale and packed to within 10nm of one another, quantum effects act to prevent energy loss. The projected result is a wonderful world of rapid recharges and storage of up to ten times the energy current lithium-ion packs can hold, as well as the potential for data retention. The only problem? It would take a year just to build a prototype, meaning we can expect market availability somewhere between a score from now and just prior to the underworld morphing into an ice rink.

IEEE begins work on new cellphone battery standard, we circle 2029 for ratification
You’ll excuse us for poking a bit of fun at the IEEE, but after it took seven years to finalize a wireless standard that didn’t change for most of that time, we have to wonder how long a new battery rulebook is going to take. IEEE Std 1725 is the current set of commonly agreed rules, in effect since 2006, but apparently “the cellular industry has grown tremendously since then” and our needs as consumers have changed. No kidding, 1GHz processors and 1080p video recording can kind of do that. The Cell Phone Battery Working Group (a real entity!) will hold its first meeting on the topic in February, and the final outcome will lay out up-to-date rules on the requisite quality, reliability, construction, and discharge characteristics of modern cellphone batteries. Let’s hope “smartphones that last more than a day” figures somewhere on that list.

Stanford wants to roll its own paper batteries
digg_url = ‘http://digg.com/hardware/Stanford_to_Reveal_New_Energy_Preserving_Paper_Battery’; It was only a couple of months ago that MIT was wooing us with the energy-preserving properties of carbon nanotubes, and in a classic act of oneupmanship Stanford has now come out and demonstrated paper batteries, which work thanks to a carbon nanotube and silver nanowire “ink.” We’ve seen this idea before, but the ability to just douse a sheet of paper in the proper magical goo and make a battery out of it is as new as it is mindblowing. Battery weight can, as a result, be reduced by 20 percent, and the fast energy discharge of this technology lends itself to utilization in electric vehicles. The video after the break should enlighten and thrill you in equal measures.

Energizer promises new and improved zinc-air battery for summer 2010
Energizer has been working on zinc-air batteries for quite some time now (along with plenty of others), but it looks like its now finally set to deliver with a new “standard battery” that’s said to be on track for a launch sometime in the summer of next year. What’s more, while some of the company’s previous attempts at zinc-air batteries have only been able to manage average run times of between one and three months, Energizer says it’s recently been able to triple things in time for the batteries’ big debut. That will first come in the form of some AAAA batteries from Energizer itself, which will apparently be priced similarly to “special lithium batteries,” and will eventually be followed by zinc-air batteries in a range of different sizes. During the same time, we should also start to see some of the first products with integrated zinc-air batteries from some of the 30 odd OEMs now working with Energizer, who are working to put the batteries into everything from Bluetooth headsets to remote controls to portable audio players.

Ultrathin, algae-based batteries could charge things you never thought possible
Somehow or another, we’ve figured out how to send mere mortals to the moon, create (and mass produce) a laptop thin enough to floss with and add multitouch capabilities to a mouse. But for whatever reason, we’re still stuck using AA batteries that last approximately one-fifth as long as you need them to. Outside of a few breakthroughs here and there, the battery industry at large has found a holding pattern that digs at consumers and likely fattens the wallets of those in charge. Thanks to new research surrounding the use of Cladophora (green algae) in a flexible, ultrathin alternative, it looks as if we may finally be onto something good. Researchers purport that these super skinny cells could be placed in areas where batteries are currently unable to go — think of perpetually charged wall sensors, energized clothing or even light-up wrapping paper. Better still, prototypes have shown the ability to hold a significant charge, but unfortunately for us all, no specific production date has been pegged. A boy can dream though, yeah?

South Korean researchers devise a safer lithium ion battery
While some researchers are focused on making batteries that are both safer and longer-lasting, it seems like the folks at the Korea Atomic Energy Research Institute (or KAERI) are simply concerned with making ‘em really, really safe. To that end, they’ve now announced that they’ve managed to develop a new type of “separator” that is said to be far more resistant to heat and impact than traditional polyethylene separators. Made from a mix of polyethylene, nano-alumina and flourine-based resin that has been subjected to radiation, the new separator can supposedly hold up to temperatures of 150 degrees Celsius and “considerable outside impact,” and it can apparently be applied to all sorts of lithium-ion batteries — including everything from phones to laptops to electric cars. Of course, there’s no word as to when we might actually see the new and improved batteries, but KAERI has apparently already applied for the necessary patents for the new technique.
