So, the idea is really cool. But, it really is just the same wireless charging that most phones use now.
Obviously a little more powerful, but the max separation is 4 inches.
So its not like they are beaming the power 50 or 100 feet up to a drone.
The drone would essentially have to land on a charging pad.

Tech Inspired By Nikola Tesla Charges Drones In Mid-Air

Everything that flies must eventually land. Unless, say, it's an all-electric drone that can recharge while in flight. Researchers at Imperial College London have demonstrated a way to transfer electricity wireless to a flying drone. Even better: they did so building on a concept pioneered by Nikola Tesla.
From Imperial College London:
The technology uses inductive coupling, a concept initially demonstrated by inventor Nikola Tesla over 100 years ago. Two copper coils are tuned into one another, using electronics, which enables the wireless exchange of power at a certain frequency. Scientists have been experimenting with this technology for decades, but have not been able to wirelessly power flying technology.
Removing the battery from an off-the-shelf drone, the researchers attached a copper ring to the drone's electronics.
