Steering wheels: sure, they're fun and functional, but why do they have to be so opaque? It's like you can't see through them at all! Our friends at CTA Digital -- purveyors of such fine gaming peripherals as the Wii bowling ball and the Nintendo DS/DSi Puppet Pouch -- are thinking outside that particular box with the aptly named Transparent Steering Wheel. Looking like something pulled from the wreckage of Wonder Woman's invisible plane, the TSW is nothing more than a transparent (well, translucent if we're being nitpicky) piece of plastic shaped like a steering wheel, which promises more precise driving on the Kinect racetrack. The company's apparently still perfecting the clear-plastic technology, which will ship June 5th, setting you back $12.99.
As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg
