Inductive charging, really?

NO RATINGS
Looks like a great science experiment and engineering challenge but I can't see the practicality of it.  90% efficient is spectacular for inductive charging but far below what can be achieved with plug in.  With the costs of electricity involved here 8-9% efficency is large.  If you've got to have your car parked for two hours or more then the effort of plugging it in is very minor.

Is the vision that we would install inductive coils in our garages?

Cool feature but not very practical.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
