Wireless electricity? It's here

Katie Hall was shocked the second she saw it: a light-bulb glowing in the middle of a room with no wires attached.Looking back, it was a crude experiment, she remembers: a tiny room filled with gigantic copper refrigerator coils the kind you'd see if you cracked open the back of your freezer. She waled in and out between the coils and the bulb and still the bulb glowed.  Katie said:" Let's work in this. This is the future." Don't worry about getting zapped Dr. Hall assures that the magnetic fields used to transfer energy are "perfectly safe" in fact, they are the same kind of fields used in Wi-Fi routers.
