Not really new but quite interesting:
"He used a DJI Mini2 drone with adequate payload capacity to lift a length of fine-gauge magnet wire 100 meters above ground. A metal mesh collecting electrode was attached to the wire and suspended beneath the drone. To complete the circuit between the drone and the ground, some large nails were driven into the ground. He also utilized a DIY electroscope to demonstrate the type of static charge that was building on the electrode. And amazingly, an electrode was able to deflect the leaves of an electroscope, power a beer can version of a Franklin bell, and run a homemade corona motor".

Could we run such a wire up a tall tower block?
