Hasta La Gadget!

That black dot isn’t a battery, it’s an ultra-thin disc containing thousands of individual nanowire batteries. Rice University scientists claim their miniscule wires are “as small as such devices can possibly get,” because each one comes complete with its own anode, cathode and gel-like electrolyte coating. This contrasts with previous examples we’ve seen, which bolted nanowires onto a chunky exterior cathode. On the other hand, these new all-in-one nano-batts only last for 20 charge cycles, so personally we’re still betting on gooey Cambridge crude to be the next big thing in electricity. Full PR after the break.

We’ve seen some rather inventive USB chargers in our time, but surprisingly few have managed to make charging while traveling a painless process. Aviiq’s new Portable Charging Station, on the other hand, has threatened to make the outside world a more welcoming place when it comes to juicing up. Acting as a sort of USB hub in a bag, this little black travel sleeve lets you pack and power three USB devices — even an iPad — with one outlet. What’s more, the station allows for easy syncing by way of a retractable USB port. So $80 ain’t cheap, and it won’t cook up pork and beans while you sing Camptown Races, but if you’re willing to shell out a little extra scratch for a practical USB travel charger, you can get your hands on one at the source link below. Full PR after the break.

Those batteries have probably met a worse fate than the white MacBook line they came from. According to Forbes, Charlie Miller’s managed to render seven of them useless after gaining total access to their micro-controllers’ firmware via a security hole. Evidently, the Li-ion packs for the line of lappies — including Airs and Pros — are accessible with two passwords he dug up from an ’09 software update. Chuck mentions that someone could “use them to do something really bad,” including faulting charge-levels and thermal read-outs to possibly even making them explode. He also thinks hard-to-spot malware could be installed directly within the battery, repeatedly infecting a computer unless removed. Come August, he’ll reportedly be detailing the vulnerability at the Black Hat security conference along with a fix he’s dubbed Caulkgun, which only has the mild side-effect of locking-out updates by Apple. Worth being safe these days, though. Right? Full story in the links below.

Ever feel like your WiFi devices’ battery-lives are better off when not surrounded by peers and passersby? According to Duke University grad student Justin Manweiler and assistant professor Romit Roy Choudhury, this phenomenon is due to gadgets constantly fighting to retrieve the same data. Their Systems Networking Research Group has created a program dubbed SleepWell to alleviate the congestion; it puts WiFi to rest until the path is clear for accessing the specific data it needs, and provides improved power management all the while. The tech was shown off at MobiSys 2011 this past week and reportedly works well “across a number of device types and situations.” Notably, Microsoft and Nokia (amongst others like Verizon) are backing up the project, which makes us cautiously optimistic that it could be headed for WP7 (or Windows 8, for that matter) in due time. There’s no info on whether SleepWell will ever be distributed commercially, but may we suggest an LTE version to help out big V’s poor ol’ T-Bolt?

Update: We’d like to clarify that this software currently works from the accesss point side rather than the individual devices. You’ll a find an additional PDF about the project in the source links below.

Better Place continued on its quest of global EV-battery-switching domination, Tuesday, bringing its special drop-and-swap charging solution to the fine folks of Gladsaxe, Denmark. An automated robot arm ceremoniously traded out the battery in a Renault Fluence Z.E., marking the beginning of a nine-month roll out across the country. The aptly titled Battery Switch station is the first of its kind in Europe and the first of 20 to be installed in Denmark. It was a monumental occasion, to be sure, one that could have only benefited from a performance of Michael Jackson’s Heal the World as sung by Danish humanoid (and ladies’ man) Geminoid-DK. Full PR after the break.
