Bob seems to be talking about the Qualcomm Halo™ Wireless Electric Vehicle Charging that they're talking about. Very difficult to imagine this will be cheap enough and scaled to model trains anytime soon.
I suspect some will squawk about the 90% efficiency, that's a pretty big hit to avoid plugging in.
Quick and efficient wireless charging technology
Quick charging with high power WEVC, supporting wireless power transfers at 3.7 kW, 7.4 kW, 11 kW and 22 kW with a single primary base pad and wireless power transfer efficiency of 90%+.

According to the link John provided, Qualcomm is using is “resonant magnetic induction“ which is quite a bit different than inductive charging.

it’s just a matter of time before someone miniaturizes the technology so it can be used in things like our trains.
