I really wish people who talk about wireless charging would do some math.

To get any efficiency, you need to tightly constrain the EM field, at which point, you are effectively hitting a plug anyway.

Or, you are accepting enormous radiative losses and losing massive amounts of power. Doubling or tripling the power draw in every device just so it's powered wirelessly is a non-starter.

For cars, we're more likely to get automated charging stations that just plug themselves in. That's going to be a useful problem to solve.
