We do semi-automated analysis of imagery of things like utility right-of-ways and it's pretty scalable. We triage the vast majority of images automatically and then surface a small subset to human experts to review, but it's much, much faster than having the experts be in the field, while having high coverage. (Most images are really boring.)

And in most cases of inspection, you need to look at the stuff anyway, so any cost reduction is very welcome. And if you do increase the total coverage volume while reducing human time, you get a double benefit of being able to provide more granular information, either in time or in space, which can often be useful.

(And as a commenter below notes - this all works pretty well with several year old CNNs. We use a limited amount of image-LLM stuff to surface things zero-shot, but a lot of what we end up doing is a very conventional classifier with a lot of engineering work to make it very fast for the experts to see only the important things.)

That was my thought as well...I suppose there may be something I am not thinking of. Perhaps they get more total energy if they "perch" on the tower.

It'll definitely charge faster, if only because it's drawing less power to stay up and getting closer. The only question is, is it like 10% or 100% faster?

Drones consume something like 100W to stay in the air (ballpark, of course), so they'd probably never charge if they had to hover.

I'd assume otherwise you have to have a way for the drones to meter their usage and pay the power company. It will likely make power theft easier, but it seems entirely viable to have an account with the power company where you report "I drew X joules from line Y" and for them to bill appropriately.

That seems entirely unviable to me. Have you met… people? “Trust me, bro!” is something I wish my power company would do, but they installed a meter instead.

Unmetered electric service based on "trust me bro" is actually the default (at least in the US) for a huge variety of devices, like streetlights, cell towers mounted to electric poles, public irrigation systems, etc etc.

Almost every US utility has a "UM" process to self-assess an unmetered load's consumption and be billed. So, yes, it's not only viable but widespread.
