A number of cold weather American states are reporting their dismay at finding out that
LED traffic lights are so energy efficient that they do not produce enough excess heat to dissipate any snow that covers them. It turns out, perhaps in an homage to bad engineering everywhere, that the inefficiency of
incandescent light bulbs was previously
relied upon to keep traffic signals unimpeded.
The new LEDs do not achieve the same effect, which has resulted in a few accidents and even a death being blamed on obstructed traffic lights. Feel free to apply palm to face now. It's not all gloomy, though, as the majority of people are said to treat a dysfunctional traffic light as a stop sign (how clever of them), and a tech fix is being worked on as we speak.

The path back to LCD leadership for Sharp begins at its just opened
Sakai City manufacturing facility. Being a
10th generation facility means it can roll out more and bigger displays, producing six 60-inch LCDs from each glass substrate, 60% more than older 8g facilities. Check out the pics for a peek at where 72,000 substrates per month will be made, delivering those slim LED backlit televisions getting so much love, along with solar panels (also being installed on the roofs for that extra green vibe that's in vogue these days) and a few of the more than 100,000 energy efficient LEDs lighting the factory itself. Whether your closest HDTV purchase is a turkey fueled memory from last weekend or yet to come, bargain hunters and AV fans alike can appreciate an eyeful of the robots and testing equipment slicing, dicing and stamping screens headed for shelves nearby, whether bearing an Aquos brand or
any number of other nameplates.

AMD has just outed a selection of new Athlon II procs, which do little to help it reclaim
the performance crown, but will be of interest to anyone who likes to keep things minimal -- whether we're talking about prices or temperatures. Starting at $69 per chip (when bought in bulk) with the 2.7GHz dual-core X2 235e and topping out at $143 for the 2.3GHz quad-core X4 605e, AMD's new e-tagged processors operate within a 45W thermal envelope, as opposed to the relatively standard 65W TDP. The Sunnyvale outfit makes some ill-advised claims of "up to 75 percent" better performance versus comparable Intel CPUs -- the small print tells us that number is derived from 3DMark Vantage while testing with different GPUs -- but we suppose until the
Thuban six-core shows up, AMD will have to take performance gains from wherever it can get 'em, including its own imagination.

Texas Instruments is pretty chuffed with itself right about now, as it's prepping to demonstrate a swell-sounding new system-on-chip that takes
Bluetooth connectivity to the
extreme reaches of low energy consumption. About to be shown off in Munich tomorrow, the new CC2540 takes up a measly 6mm-squared of real estate, and is said to be able to operate for more than a year on a single button cell battery. With the reduced physical size and embedded Flash memory, this should be easier to install and update as necessary too. Considering the battery-draining ways of current Bluetooth tech, such claims sound preposterously awesome, but we'll keep our giddy enthusiasm in check until early next year when samples will begin rolling out. For now, you can check out the older video below 'splaining the prospective benefits in more detail.

Leave it to a gaggle of brilliant wood science researchers at Oregon State University to figure out that we've been doing this whole "
tire" thing wrong for generations now. While studying some uses of microcrystalline cellulose, which can be made easily from practically any type of plant fiber, these Earth-loving gurus discovered that said material could actually
improve the efficiency of vehicle tires when used in place of silica. Granted, only about 12 percent of the silica -- which is used as a reinforcing filler in the manufacture of rubber tires -- was swapped out, but the resulting tires gripped just as well in wet weather while decreasing the rolling resistance during those dry summer months. Furthermore, tires constructed with these fibers could be made with less
energy, though long-term durability studies are still needed to prove that this whole plan is viable for more than a few thousand miles.

There's certainly no shortage of company's working to make electronics of all sorts more
energy efficient, but NEC and Rohm Co now say that they're on the verge of a breakthrough that could change things in a big way, and we could possibly see it in "practical use" by the end of this year. As
Tech-On! reports, both companies are hard at work on integrated circuits that consume no power at all when they're in standby mode, and turn themselves on only when power is needed. That's apparently possible by making the entire chip nonvolatile, as opposed to many current chips that only use nonvolatile merged memory. According to NEC, that'll let them "cut dissipation for digital consumer electronics in the standby mode to just a few percent of what it is now," and at no expense of convenience. While NEC isn't making any promises for the near future just yet, Rohm says that it'll begin shipping its first custom ICs in the second half of this year, and that the first products using them could start showing up by the end of 2009.

We've seen
all sorts of devices that
learn over time, though most of them fall into the
humanoid category. Now, a team of gurus over in the UK has developed an entire home that can learn from those dwelling in it and react in order to curb energy waste and even prevent unauthorized entry. InterHome, a model designed by researchers at the University of Hertfordshire, is scheduled to be unveiled at the Microsoft Imagine Cup finals, and it should make other home automation systems look rather antediluvian in comparison. By sensing how the owner(s) like their climate and such, it can reportedly save up to £300 a year in energy costs alone. Furthermore, it can "take decisive action and text if it is being burgled or the door has been left unlocked," and the whole system can be monitored remotely and controlled via the web. Too bad we're terrified that it could one day turn on the owner and refuse to allow entry to anyone other than leaders of
The Resistance, but other than that, it sounds pretty nifty.
