Hasta La Gadget!

It’s rush hour, and you’re headed due West on your evening commute — the sun burning holes in your eyes. You could flip down a window visor, trading your field of view for visibility. Or, with a prototype shown off at Intel’s 2010 International Science and Engineering Fair, you could simply let the windshield darken on its own. Two San Diego students (both accustomed to copious amounts of sunshine) rigged a Toyota Prius to do just that by stringing up electrochromic panels, which dim when voltage is applied. The trick is figuring out when and where to apply it, because when the sun is shining the panels themselves all receive the same amount of light. So instead of gauging it at the glass, Aaron Schild and Rafael Cosman found that an ultrasonic range finder could track the driver’s position while a VGA webcam measured the light coming through, and darken the sections liable to cause the most eyestrain. We saw a prototype in person, and it most certainly works… albeit slowly. If you’re rearing to roll your own, it seems raw materials are reasonably affordable — Schild told us electrochromic segments cost $0.25 per square inch — but you may not need to DIY. Having won $4,000 in prize money at the Fair, the teens say they intend to commercialize the technology, and envision it natively embedded in window glass in the not-too-distant future. Here’s hoping GM gives them a call. See pics of the Prius below, or check out a video demo of their prototype right after the break.

Look, we’ve no beef with Osram Sylvania (nor Artison, for that matter), but calling these MusicLites “a first of its kind” is a bit of a stretch, if not an outright falsity. Klipsch launched essentially the same thing back at CES this year with the LightSpeaker, but hey, we’ve no gripes with a little competition in the space. The aforementioned duo has joined up in order to produce something that should make the art of integrating whole home audio into your own abode a good bit easier, with the MusicLites design combining a 10-watt LED light, a 70mm full-range loudspeaker and a wireless audio receiver. The device can slide into four-, five- or six-inch recessed cans, and we’re told that it’ll provide light output equivalent to a 65-watt reflector bulb. As you’d probably expect, there’s a proprietary 2.4GHz transceiver that works with a variety of sources, some of which include USB, smartphones and PMPs. Each kit will ship with a pair of 3.8″ x 5.3″ modules and a remote that controls light dimming and audio settings, and while mum’s the word on pricing, it’ll be commercially available sometime in the fall.

It might not change the world, but it won’t be for lack of trying. Plus Minus Solar has designed what it’s calling the LED Solar Pebble, a multifaceted device that requires just a pinch of sunlight (or maybe gobs of it, actually) in order to generate artificial light. And charge your arsenal of gizmos. It’s engineered to be built at a low cost and used in developing nations, but unfortunately there’s no confirmation on what exactly it’d charge. ‘Course, it’s just a concept as of now, so we’re guessing a micro-USB and mini-USB socket could be tossed on by whatever manufacturer would be kind enough to get this to a production line. Right, prospective manufacturers?

Lenovo loves its red mousing nipple, Apple digs its aluminum and IBM adores those light pulses. Nearly two full years after we heard this very company touting breakthroughs in science thanks to a nanophotonic switch, in flies a similar technique from Yorktown Heights that could “greatly further energy efficient computing.” As the story goes, gurus at IBM have figured out how to replace electrical signals that communicate via copper wires between computer chips with tiny silicon circuits that chat using pulses of light. The device is called a nanophotonic avalanche photodetector, and according to Dr. T.C. Chen, this kind of embedded optical interconnection makes the “prospect of building power-efficient computer systems with performance at the Exaflop level” something that could be seen in the not-so-distant future. Reportedly, the avalanche photodetector demonstrated by IBM is the world’s fastest device of its kind, able to receive optical information signals at 40Gbps and simultaneously multiply them tenfold. We know that’s over some of your (read: our) heads, but there’s a sufficiently nerdy video after the break that gets right down to the whos, whats, whys and wheres.

It’s 2010, which means there’s a significant chance that your cubicle work could be done from absolutely anywhere. For those still stuck under the burden of old-school management, here’s an idea that might just nab you that raise you’ve been longing for: the CubeTube. Engineered by Solaroad Technologies, this indoor photovoltaic electrical generator straps onto the edges and tops of conventional cubicles and collects light from every angle. Internal batteries are charged up, and power is instantly available for the decade-old Latitude and CRT monitor that’s still residing on your desk. It sounds like you’ll need to ping the company directly for pricing quotes and the like, but if you managers are seriously considering this for your office, maybe they should first calculate the cost and carbon savings from letting their subordinates telecommute. Just sayin’.

Solaroad’s CubeTube adds solar panels to your cube, lowers the cost of you working there originally appeared on Engadget on Wed, 24 Feb 2010 21:45:00 EST. Please see our terms for use of feeds.
