Nothing new
This really isn't all that new...I demonstrated this very concept in a science project in the early sixties and it can be duplicated. It's really simple...electrical current simply follows magnetic lines of flux to a contact. As long as the flux lines (not to be confused with the Flux Capacitor) can bend around an interference, they can conduct current.
This little tidbit was discovered when an electrical wire going from a 1.5V D Cell battery to a motor using a strong horseshoe magnet in a toy boat broke off and the motor was still running. Found that current was transferred up to about 6 inches away. It stands to reason...more available current with stronger, more focused magnetic lines of flux means farther transfer distances. Anyone can repeat the experiment--I'd use a horseshoe magnet motor.
Can imagine that they are focusing the magnetic field to induce a better transfer of current, but there is still that magnetic field that can raise havoc with everything else. It's not such a good idea--in fact, the class instructor, a stereo buff at the time, did a check of some sort and found all kinds of noise was generated from the transfer (have no idea what the noise was). Maybe they have figured out a way around that problem, and maybe not. But, before passing judgment, there is a need for more info, such as: potential for noise generation in audio/video equipment, interference caused by the magnetic fields, are they using two way DC power transmission or single way AC transmission, etc.
