You're talking about inductive charging, which is basically how electric toothbrushes charge. It's recently been built into new devices (my Nexus 4 supports it) but obviously requires they be placed on a charging mat/station. Perhaps in the future it could be built into desks, so that everything placed on them charges. I would imagine (but I'm no EE/physicist) that these get terribly inefficient when you scale them up.
