I'm still extremely skeptical about this. The inverse square law is a huge hurdle, power delivery rate has got to be minuscule.<p>This isn't making a better charger, it's making better physics.
No idea about speed of charge. That's what the game is right now. I used to have a phone with wireless charging but it was way slower than using the wired smart charger (the one with the tech from Qualcomm)
On one hand, it's crazy that they pulled this off, of the other hand, I'm not sure if I see the practical applications of near-range wireless line-of-sight charging
