Wireless charging only seems unbearably stupid because you are thinking of standard, non-resonant induction. Resonant induction is much more efficient. "The fields used are predominately non-radiative" http://en.wikipedia.org/wiki/Resonant_inductive_coupling http://en.wikipedia.org/wiki/Resonant_inductive_coupling edit: The article is not referring to resonant induction or standard induction, but using ultrasound instead.
