I see batteries as being a dead end.  They're entropic, which is a fancy 
way of saying that they wear out with use.  It's inescapable.

I see room-scale broadcast power as being the real game-changer. 
Resonant inductance won't replace batteries, but it will change how they 
are used.  Batteries won't be primary power sources.  They'll be buffers 
to cover short term signal loss when moving between rooms or while 
commuting.

Resonant inductance works on the small scale.  Our "good friend" RFID 
operates on resonant inductance.  RI power has been demonstrated at real 
world room scales.  It's not yet cost effective but solving that is just 
a matter of time.
