Switchable graphics solutions duel it out, AMD ends up looking like a chump
At this point, NVIDIA's Optimus switchable graphics are old hat, but AMD is relatively new to the game of packing dual GPUs in a single laptop. AnandTech decided to pit the two solutions against each other and, well, lets just say AMD doesn't come out looking so great. The biggest problem appears to be stability. While performance is acceptable (though, not quite as good as it should be) the site had trouble getting four of the supposedly 16 supported games to switch between the integrated and discrete GPUs as advertised. Regular driver updates, not to mention a bit more testing, could solve the issues, but for now NVIDIA's Optimus simply outclasses its AMD counterpart.

AIST turns transparent glass into mirrors to conserve energy
We've seen two-way displays and undercover mirrors before, but the latest two-faced invention to come from the depths of the National Institute of Advanced Industrial Science and Technology (AIST) can pull double duty in regard to purpose and save a little energy in the process. The "switchable glass" has certain reflexive properties created by the twin coatings of "40-nanometer-thick magnesium-titanium alloy, plus a 4-nanometer-thick layer of palladium," which allows for the mirror to become transparent when a small amount of hydrogen is introduced between the two panes. Alternatively, tossing in a bit of oxygen forms a reflecting mirror, allowing users to "switch" the glass by injecting gases. Contrary to other commercialized approaches, this rendition can purportedly result in up to a "30-percent savings in energy costs" by having to run your air conditioner less, but there's still work to be done. Scientists at the AIST are still toiling away as they try to fight the relatively rapid deterioration that occurs from "frequent switching," but if they can add a dash of durability and get the price down to a respectable level, we could all be living in a house of mirrors before too long.[Via PlasticBamboo]
LG's 42-inch 2D/3D switchable HD LCD TV
As part of its "extensive" coverage of this year's International Meeting on Information Display in Korea, AVING has a brief write-up on a 42-inch LCD monitor from LG that can switch between 2D and 3D modes at the touch of a button. And by "brief write-up," we mean just that; it's literally a one line mention of the HD-capable set, with no explanation as to how it performs this amazing feat. We suspect that the company has been working with Philips and implemented its WOWvx 3D technology, which provides auto-stereoscopic images without the need for those silly-looking, 50's era blue and red glasses. There's a good chance that this monitor will be on display again at CES, though, in which case we promise to provide you with the full deets (or at least a post containing a little more of the technical jargon that you love).
