That’s not the way they spin it of course. They are using the highly dubious magnetic field coupling that the MIT guy claims is an invention. Only the near-field at high frequencies is pretty closer than a few feet, so I have to believe this is bathing the world with RF, just what we need when wireless gizmos have a hard enough time working.
This is almost criminal in a world where we need to conserve every single watt. Leave it to the digital guys to ruin it for everyone. Yeah, I know, they will claim they can fix it in software. What’s not to like about a system that is 50% efficient on top of the ac-dc conversion, and pumps RF energy all over the place? Can you see why the digital jockeys at Intel also think they can use the guard bands between TV stations to broadcast data?
And note how the always-clueless mass media reporter confuses the use of super capacitors with this technology—they are completely orthogonal decisions, what the heck does a super-capacitor storage system have to do with wireless charging?
