A couple weeks ago I talked about a patent awarded to Apple to charge devices wirelessly using induction charging. This is still viable… however, I just learned about an even better technology.
Ubeam is a tech start-up that invented a concept [demo’d] at the D9 Conference. Think of an audio speaker that plays music. It transmits radio waves from the speaker to your ears. Using ultrasound, Ubeam transmits very high sound from their charger to a charging station where you can plug in multiple devices to charge simultaneously, wirelessly. The only catch is there can’t be anything blocking it.
I think it will be a success if Ubeam gets the right funding."
