Now those eggheads at MIT have done something truly magic, figuring out a way to send power seven feet away, and look ma, no wires. Their trick uses resonant coupling, turning electricity into magnetic energy resonating at a certain frequency that proved to have that old black magic.
For some reason, 10MHz is that certain magic number. Resonating a coil at that frequency on one side of the room, it sends its magneto-goodness over to the other side where there's another coil that also resonates at that same 10MHz frequency. Yeah, for some strange reason, this magnetic energy is able to jump across a 7-foot space, but only at that specific 10MHz frequency. Cool.
There must be a catch to this.
