Infrared solar panels even work at night, but can't output energy

Solar's had a pretty rough time breaking the ~40% efficiency level over the years, but Idaho National Laboratory researchers have apparently developed a nano-antenna array capable of collecting power not from photonic energy as is done today, but from infrared energy that could be harvested in any weather (or even at night). The cell production process is even supposed to be ridiculously cheap compared to making standard silicon photovoltaic cells, but, as always, there's a rub. The grid collects its oscillating IR energy at ten thousand billion times per second, which is proving to be a challenge to the nerds behind the tech, who are working on a way to convert that to the 50-60Hz power that the world uses. So yeah, it might be a few more years before this one pans out (if it does pan out).

Maxablaster mega-flashlight is a step away from lightsaber

You thought the goggles did nothing before? Shine the 38-million-candle Maxablaster (which, we hear, has been bumped up to 52m in a recent build) and watch as faces melt Raiders of the Lost Ark style under its concentrated mercury arc plasma bulb powered by a 54 battery pack. Right now it's just the pet project of a Dutch engineer by the name of Ralf Ottow, which is probably for the best, since this would be far more effective at boring holes in concrete than lighting any scene.

Researchers devise method for colorizing metals, alchemists swoon

Filed under: Misc. Gadgets

Unfortunately, Dr. Chunlei Guo of the University of Rochester hasn't yet figured out how to turn scrap metals into gold, but he, along with Dr. Anatoliy Y. Vorobyev, has discovered how to colorize a variety of metals. By utilizing a "femtosecond laser processing technique," the duo has crafted a method for turning even aluminum into aluminum with an impeccable gold finish. Furthermore, they've also been successful in turning tungsten dark blue, leaving reason to believe that nearly any metal could be altered to appear as a different color. Ah, just imagine what these folks could do with your MacBook Pro.

Intel launching Tukwila: world's first 2 billion transistor chip

Filed under: Misc. Gadgets

We first head of Intel's quad-core Tukwila back in 2006. Now, it's launching at the International Solid State Circuits Conference. Expected to arrive in the second half of the year, the 2GHz Itanium processor packs in more than 2 billion transistors. Unfortunately, it's headed straight to the raised-floor room, not your consumer-class desktop. The good news for IT types is that the proc doubles the performance of Intel's enterprise-class, 9100-series Montvale processors with just a 25% increase in power consumption. So, we looking at 4 billion transistors by 2010 Mr. Moore? Probably, Tukwila is still using 65-nm processes as opposed to Intel's new 45-nm technology.

Asus' quad DVI-packing EAH3870 X2 1GB TOP gets previewed

As if a regular Radeon HD 3870 X2 wasn't enough to make you envious, the folks at HotHardware have now gotten their hands Asus' new EAH3870 X2 1GB TOP behemoth, which increases the insanity of the dual-GPU card even further with a full four DVI ports. In addition to making that lone s-video port look woefully out of place, those'll let you push out more pixels than you'll ever likely need across four monitors, with none of the compromises associated with lesser multi-monitor solutions. What's more, Asus' card is apparently even lighter than the original reference design for the HD 3870 X2, and you can rest assured that it'll be overclocked right out of the box. No word on a price or release date just yet, but HotHardware is promising to deliver a full review of the card if they can ever pull themselves away from their bank of monitors.
