Oh but the scenario where the drone does it without permission is just way more entertaining.
- dkjaudyeqooe 3y agoThree-quarters of a megavolt of electricity plus drones does seem like a lively mix.
- rtkwe 3y agoThere's no current though, the same way birds can sit safely on lines all day long.
- dclowd9901 3y agoThere is definitely current or there would be no wattage.
- pineaux 3y agoI dont know. There is definitely a flow of energy between the power line and the drone. But there is no closed circuit between them so there is no current flowing. I imagine there is a (slightly, almost not measureable) raised current in the powerline due to a lower resistance due to the parasitic voltage drop and phase shifting cause by the inductive load. So technically no current between the drone and the powerline. Although there is energy transfer. But there are probably lots of people here that understand the laws of electromagnetism a lot better than me.
- rtkwe 3y agoThe current for charging comes from magnetic induction but touching just the wire gives no voltage differential for current to flow across.
- jefftk 3y agoIt's hard to induce a current in a bird.
- baq 3y agoWhere is there no current? The video says 300A if I heard correctly
- olex 3y ago300A of current is going through the wire, at high voltage - that's the transmission current. Drone is not charging directly from that, it lacks a ground / other phase connection to directly tap into the wire voltage (also, it lacks a... power substation and a bunch of other stuff to step down and convert the high-voltage AC from the line to low-voltage DC for the battery). Instead it uses an induction charger that "leeches" off of the magnetic field of the wire. If the wire current is higher, the magnetic field is stronger, so it can pull more power than the currently possible 50W.
