This T-shirt converts sound waves into electricity to charge a cellphone—just in time for music-festival season!
Go ahead and pump up those jams, because a new technology that turns sound into electricity—enough to charge your cellphone or portable device—is about to revolutionize musical festivals everywhere. And the magic begins in your T-shirt. The high-tech tee, known as “Sound Charge,” is the brainchild of British telecommunications firm Orange , which will debut the prototype at England’s famed Glastonbury Festival this weekend. A collaboration with the renewable-energy experts at GotWind , Orange’s sound-absorber takes amplified acoustics and converts them into a steady charge. In other words, you can keep your mobile juiced simply by hanging out at a concert.
