No more phone chargers uglying up your home?

Not yet. But the following article in Gizmag reveals that Korean scientists are looking for ways to charge cell phones from the energy of your voice! It's the reverse process of how speakers turn electricity into sound waves, and while it's not too efficient there are hopes that eventually we can get rid of those ugly wall warts on our desks and kitchen counter tops and charge our phones by calling mom. Other options may be to turn ambient noise into electricity as well, so that guy with the leaf blower outside my window right now would actually be charging my netbook instead of just being annoying.

The exciting part for us organized people is that we could have less of those tangled charging cords in our home to organize!
