Not yet.

What's actually needed are induction chargers. Plugging in a plug erode 
the mating surfaces. Putting a receiving coil above a charging coil doesn't.

I recently upgraded my mobile phone to one that accepted inductive 
charging after the charging socket on it's predecessor had worn out and 
had to be replaced,

Not true.

Not a problem. there are already electric buses in service that get 
recharged by parking on top of an induction buried in the road under the 
last stop on their run.

But that does emit CO2 in operation, if not as much as a regular 
internal combustion engine.

Nobody who has ever worked on capacitor energy storage would take that 
seriously. The energy density on offer is utterly inadequate.

And they are hopelessly inefficient.
