China’s ‘land aircraft carrier’ charges flying drone with microwave beam (www.scmp.com)

Scientists in China have demonstrated a wireless power transmission system that uses a ground-based microwave emitter to beam energy to an antenna array mounted on the aircraft’s underside. Importantly, they were able to do this while both the drone and charging system were in motion.

In tests, the car-mounted system kept fixed-wing drones in the air for up to 3.1 hours at an altitude of 15 metres (49 feet). The key challenge that the team overcame was maintaining alignment between the emitter and the drone during flight, wrote Song Liwei, the project’s leader.

I have no knowledge in this and it's early, but what happens to birds in the medium in between the receiver and emitter?

This can't be good for them.
