You can hold up fluorescent tubes under high voltage power lines and they will light up.

I've always wondered why drones didn't just come with qi charger landing pads.

Weight, qi chargers aren’t just an antenna they require power handling electronics. Getting the exact right DC voltage to charge a battery from two lightweight wires is just simpler internally.
Let's take that a step farther and have the drone implement direct coupling and charge while flying near the power lines.
Guessing a magnetic torque would be applied while flying that said drone would have to counter.
