Yeah multiply the weight of 1/2 mile of fiber by 20 to 50 tangled strands and try to drag it.

It's not even just 1/2 mile. I read an article recently that 15km spools are already in use and 20km spools are actively being tested.

[–] anomnom@sh.itjust.works 4 points 3 days ago (1 children)

Is the tensile strength anywhere close enough to reel it back? I assumed the spool is carried by the drone, not dragged from the source.

It’s a really interesting/terrifying technology. But it’s gonna a be a mess to clean it up.

Tensile strenghth is definitely enough. Ive used fiber to tow vehicles before in a pinch. A single strand takes a surprisingly higher amount of force to break than one would expect. Good luck pulling a window pane in two..
