Four years ago, we first heard about how Korean scientists had proposed using sound to charge mobile phones. They explained that it could be done via a piezoelectric effect, in which zinc oxide nanowires converted sound-caused vibrations into electricity. At the time, the researchers couldn't generate enough of a current to actually charge a phone. Now, however, scientists from Nokia and Queen Mary University of London (QMUL) have succeeded in doing so. Read More

These days, most people are inseparable from their mobile phone, with the device being one of the essentials along with keys and cash or cards that people don't leave home without. A project at EPFL's Mobile Communications Laboratory is looking to take advantage of this fact by developing a drone that would help rescuers search for victims of natural disasters by locating their phones.

By - February 18, 2014 9 Pictures
Around the world there are hundreds of millions of discarded mobile phones lying around in drawers and boxes, displaced by the bigger screen or better camera of the latest version. But truth be told, even if we were talking about hundreds of billions it would be unlikely to elicit a much different response, because ridiculously big numbers are ridiculously big numbers, right? Seattle-based photographer and activist Chris Jordan is on a mission to make these measures of consumerism manifest through visual art and, as he explained to Gizmag, bridge the disconnect between our mass consumption and its largely invisible consequences.
