Hasta La Gadget!

Mama always told us that there’d be trade-offs in life, but we aren’t so sure we’re kosher with this one. As the story goes, a team of Wolverines from the University of Michigan figured out a solution to an age-old problem: effectively lowering power consumption by a significant amount in electronic devices. Anyone with a smartphone yearns for better battery life, and while Stevie J may argue that no one reads for ten hours straight, we’d still rather have the option than not. The development revolves around “near-threshold computing” (NTC), which allows electronic wares to operate at lower voltages than normal, in turn lowering energy consumption. Researchers estimate that power energy requirements could be lowered by “10 to 100 times or more,” but unfortunately, that low-voltage operation would lead to “performance loss, performance variation, and memory and logic failures.” We appreciate the hard work, folks, but could you hit us back when the side effects are somewhat less daunting?

We’ve seen the magic of piezoelectrics before, but if a team of Cal Bears can really deliver, their spin on things will actually make a difference in the retail realm. Engineers at the University of California, Berkeley have concocted so-called “energy-scavenging nanofibers,” which could one day be “woven into clothing and textiles” in order to convert into electricity the energy created through mechanical stress, stretches and twists. If everything works out, these movement-lovin’ clothes could theoretically power your phone and / or PMP as you walk, and for those concerned with cost, we’re told that the organic polyvinylidene fluoride materials use to make the nanofibers are easy and cheap to manufacture. Too bad there’s no direct confirmation that PVDFs are machine washable, but hey, that’s why you’ve got the local dry cleaners on speed dial.

Meysam Movahedi’s latest concept certainly isn’t the first revolutionary tweak to the tried-and-true power outlet, but it’s easily one of our favorites. Put simply, the Rambler Socket is an in-wall box that contains 1.5 meters of extra cabling along with a traditional AC outlet. Granted, you’ll need a pretty deep wall to make something like this work (in theory, of course), but the result is nothing short of brilliant. If your AC cord is long enough, you simply plug it into the socket per usual; if you need a little extra length, the built-in extension cord pulls out with a gentle tug. Once you’re done, you simply tug on the cable once more and watch as it recoils back within the wall. GE, or someone — can we get a contract to this guy, pronto?

Spintronics — much like Cook-Out milkshakes and cotton candy for all — seems like a pipe dream at this point. We’ve been beaten over the head with theoretical miracles, but we’re getting to the point where it’s put up or shut up. Thankfully, a team of Dutch boffins are clearly in the same camp, and they’ve been toiling around the clock in order to achieve spin polarization in non-magnetic semiconductors at ambient temperature. The amazing part here is that “temperature” bit; up until this discovery, spin polarization was only possible at levels of around 150 K, or at temperatures far, far cooler than even your unheated basement. If spintronics could effectively be enacted at room temperature, all those unicorn-approved phenomena we mentioned earlier would have a much greater chance of sliding into the realm of reality. Here’s hoping they get this stuff ironed out prior to 2012.
