And here I thought drones were radio controlled...

[–] varyingExpertise@feddit.org 16 points 6 days ago

They were, now they aren't.

You can interfere wirh radio waves, but not a fiberoptic line

My scissor begs to differ.

And how long are you going to survive in the no man's land, operating your scissors?

I think I could manage a good few seconds.

Man, that's gotta be hell on any wildlife left living in the areas in which it's used. (I mean, I get the necessity, but dang)

Tillers too when this war ends (with Russia's defeat) and it's time to plant crops.

Just wait until people realise the steepness of the co2 emissions reduction curve has become so extreme that it is impossible to avoid catastrophic climate change without a global collapse of capitalism that in turn can only lead to kinetic world war. Which, again in turn, is the most carbon intensive activity known to human-kind, making this sort of environmental degradation a picture of the good old days.

It is a pity that most people didn't pay attention when IPCC's working group three (the group responsible for coming up with a plan to mitigate climate change), was filled with economists beholden to a [neo-]liberal economic and political ideology that 1. set the stage for the current and future governments of right wing extremists. And 2. 'discounted the future at 5%', meaning rather than plan to mitigate climate change they said: "we will invest money now in exploiting fossil fuels, which will return a profit at 5% per year. Then we will take these compounded 5%'s and invest that in co2 removal technology". (Unfortunately they missed off the: [... co2 removal technology that does not exist outside of a lab and has only been shown to be impossible at scale].)

I don't have the information that says we are now at the point of no return (I bet people like Vladimir Putin and Xi Jinping do), but publicly available information shows we have a limited number of years, and are racing in the wrong direction. Apologies maybe I am not having the best morning!

[–] Etterra@discuss.online 4 points 6 days ago

Well I mean the psychopathic and narcissistic rich bastards in charge aren't gonna feel the effects so why should they care?

[–] HasturInYellow@lemmy.world 2 points 6 days ago

You are devastatingly correct on all points. We are AT BEST a few years from the cliff. If we do avoid the cliff, it will be so extremely painful for every single person on the planet that our societies will crumble. There will be a massive population crash as industrialized agriculture is made largely impossible. The chaos in this situation is impossible to overstate.

Mind you, if we don't avoid the cliff, we still go through that, but worse.

[–] RecallMadness@lemmy.nz 6 points 6 days ago

Then the crops grow, and they’re all full of microscopic glass fibre. Then the foodstuffs are shipped to the world. Then the foods are eaten and the GF joins the microplastics in our bloodstream.

[–] lurch@sh.itjust.works 41 points 1 week ago (1 children)

the whole war is really bad for the environment. not just locally. tanks don't run on solar. burning fuel depots, etc..

we need to stop putin and his enablers.

[–] anomnom@sh.itjust.works 13 points 1 week ago (1 children)

There’s also a good chance a lot of these areas are smattered with land mines too.

So whilst the drones are super-effictive (for now) they pose several serious problems - 1. Fibres can get tangled, maybe even affecting vehicles or other machinery, cars, whatever and 2. If you can view these from the air, you can use an fpv drone to trace them back to the operator (meaning they'll need to change position more frequently and probablyclean up before returning to old positions). 3. That's gonna be a heck of a cleanup operation.

[–] 0x0@infosec.pub 8 points 6 days ago

None of your points are even remotely close to an actual problem, let alone a serious one lol

[–] Tire@lemmy.ml 2 points 6 days ago

They usually carry the spool on the drone so they don’t really get tangled because the feed end is at the source of the movement. It can always let out more slack to continue forward.

[–] ladicius@lemmy.world 45 points 1 week ago (1 children)

A war always is a "heck of a cleanup". These cables are by far not the worst part of it.

[–] l_isqof@lemmy.world 1 points 6 days ago

Us stupid humans will always find a way to kill each other.

The only question is what survives from the planet, not from our species...

[–] Olgratin_Magmatoe@slrpnk.net 13 points 1 week ago

Given how thin those are, and how many there are it might be a waste of time to try to follow them.

[–] Comment105@lemm.ee 5 points 1 week ago* (last edited 1 week ago) (1 children)

A drill and reel could wind up the fiber if the drone has exploded and the cable is loose. If the cable is still attached to the drone, it could send a signal to a device at the end to cut/blow up the fiber attached at the drone's end.

Guessing it's impractical as they're not doing it.

[–] endeavor@sopuli.xyz 8 points 1 week ago (1 children)

that works as long as the cable is on perfectly flat surface and not tangled up in any way at all.

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

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

[–] Schneemann@discuss.tchncs.de 4 points 6 days ago (1 children)

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 6 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.

[–] 0x0@infosec.pub 4 points 6 days ago

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..

[–] Railcar8095@lemm.ee 19 points 1 week ago (1 children)

Each cable can generate 80kg of fertilizer

Win-win

[–] piecat@lemmy.world 8 points 1 week ago (2 children)
[–] Aeri@lemmy.world 6 points 6 days ago

I believe the implication is that when the Drone kills a soldier their body will fertilize the ground.

Presumably a corpse.

[–] Steve@startrek.website 13 points 1 week ago (2 children)

What? Why is there so much fiber optic cable?

[–] Fandangalo@lemmy.world 52 points 1 week ago (3 children)

From Internet (not op):

Fiber-optic first-person-view drones areΒ jam-proof. Sending and receiving signals along millimeters-thick but miles-long optical fibers, these FPV drones are impervious to the radio interference that can ground wireless FPV drones. That doesn't mean it's impossible to defeat a fiber-optic drone.

[–] bitwolf@sh.itjust.works 5 points 6 days ago

So that's where all of the USA's fiber rollouts ended up

[–] tazeycrazy@feddit.uk 17 points 1 week ago (1 children)

Just need sissors and a pogo stick to bring one down.

Are they tethered to the operator?

[–] nimble@lemmy.blahaj.zone 30 points 1 week ago* (last edited 1 week ago) (7 children)

The drones have a spool of fiber optic cable. Some spools can reach 40km. The spool unwinds as the drone flies and yes it would either lead back to the operator or they could in theory have a node that it connects to and then from there connect to operator via cable or wireless. Really fascinating stuff imo

How they work:

The drones are fly-by-wire

[–] MolecularCactus1324@lemmy.world 4 points 1 week ago (2 children)

It’s initially a cool idea, but don’t the fiber optic lines give away the location of the drone operator? Or, at least where the drones are stored?

[–] LePoisson@lemmy.world 3 points 6 days ago

They spot targets first then send these fiber optic guides drones on a one way trip to killsville.

At least that's my understanding. I doubt they launch them from some central drone storage location, these drones are carried by a small team, fired off, then the team leaves the area.

I could be wrong though, I'm not an expert.

[–] _cryptagion@lemmy.dbzer0.com 15 points 1 week ago (9 children)

Sure, you hope out there in the open, you can follow them back to where they took off. And if you manage not to get spotted by a drone and blown up, you get to try killing the enemy in their tranches.

You know, just a casual, stress-free, totally low-risk Sunday stroll.
