The ability to push it through the air isn't there. You end up dumping a lot of power into the transmitter which then just heats the air around it rather than go anywhere because the oxygen is absorbing it.
It is however great for a non-contact point to point where you connect the xmitter and receiver by attaching adjoining faces together. Imagine a PCIe card where the edge connector had no electrical contacts it just sits in the slot and the connection is a 60GHz link between the card and the base board. With inductive power transfer you don't need any conductive contacts at all.
Its very cool and sciencey but the tranceivers are stupid expensive and the use case is really pretty limited.
