That is an interesting video to watch. I immediately imagine a self driving car, on its way to pick me up, swinging by this robot arm to charge up.

I wonder if it would be possible for something like this to provide a charge while moving? Like airplanes that can be fueled in the air.

I suspect the energy to keep the charger itself moving would make that a pretty inefficient way of doing things, but it's fun to imagine.
