Several years ago there was a startup doing this as well, essentially using an induction coil and they had a simple modification which made pretty much any mobile work with it. Doing it efficiently means adding some extra magic with frequency and such, and that appears to be what current research (and product) development is focusing on.

You mean the one you saw was induction charging?  They're the only ones I'd seen up till now as well.

This one is ultrasound, though I don't know why anyone would use it (and too lazy to read the web site!).

The Xi Collaboration is a step in this direction that actually has a bit of momentum, hope to see good quality inductive charging in the next year or two!
