there's a difference between wireless sending of a signal (phones, music) and an actual current. i don't expect the latter to be very safe, but we'll see.
The thing that I don't get it this.... what is stopping me from tapping into my neighbour's WiTricity supply.
Like I am sure that we all scan areas for unsecured networks. But what about WiTricity supply. That is stopping me from using my air con on as the expence of my neighbour's WiTricity bill?
