Water is a lot heavier than you think, Randy.

you see they get it from the sky, like the clouds, they don't need to bring it up

[–] Adkml@hexbear.net 28 points 4 months ago (1 children)

It was so funny watching Josh Johsnons video about how rural people are skeptical of city people because "they dont know where water comes from."

And then 24 hours later trumps saying the the answer to the fires is to use rain that comes from heaven.

[–] SpiderFarmer@hexbear.net 14 points 4 months ago (3 children)

Kinda wild to read, given how cities naturally crop up along bodies of water.

What if helicopter, but, uh, it's small? Lots of small helicopters!

Side note, anyone else love that with generative AI computers are finally able to produce shitty CGI renders but worse? Like that picture looks like something that would show up in like a mid '00s "science channel" """documentary""" about hypothetical tech that's really just a commercial for some arms dealer, but it's all mangled and fucked up because it can't even make a shitty CGI render right anymore.

wot if a single one crashes and its lithium-ion battery goes off in a wilderness area that already has extreme fire conditions? thinking-about-it

[–] bishbosh@lemm.ee 13 points 4 months ago (2 children)

Honestly that's probably best case scenario, as we would already have thousands of ready drones in the imitate vicinity. Even if emptied from previous efforts, the drones would instantly know the loss of one or more drones need to be doused, and we can deploy another 10000 or so to solve the problem quickly and cheaply.

[–] happybadger@hexbear.net 21 points 4 months ago (4 children)

Those 10,000 then fly blind into an area with high winds that creates its own weather system, can melt them, and that flings flaming particles for miles through the air. That's playing Russian roulette with 10,000 more rounds in the gun-hubris gun.

I don't know all the details/specifics but USA wildland fire crews do have drone crews that use drones for mapping purposes- to aid direction of resources on ground, and monitor conditions. As you would imagine there are extensive bureaucratic procedures for any event where a done goes down/loses control/etc, it does happen- but my understanding is that it is never/rarely catastrophic failure.

Only the dumbest motherfuckers get rich and powerful in the US it seems.

Ignoring the cringe inducing AI image, there are a few obvious problems with this idea:

  1. Water is heavy and a liquid and it's movements would throw off a drone balance very easily.

  2. A drone army of 10,000 isn't big enough to carry the water required. You would need millions of drones to even make a dent in the fire.

  3. If even one of those millions of drones were to crash, it's lithium battery would be absolutely devistating fuel for the fires because those things are near impossible to put out.

Sometimes I wonder if these guys are actually this stupid of if they're pretending.

[–] KobaCumTribute@hexbear.net 37 points 4 months ago* (last edited 4 months ago) (2 children)

it's lithium battery would be absolutely devistating fuel for the fires because those things are near impossible to put out.

This is very tangential since a tiny drone would have burned up long before firefighters could reach it to do any sort of mitigation, but with EVs becoming more of a thing and them bursting into fire being a huge problem, fire departments have actually studied the problem and worked out how to effectively suppress that kind of lithium battery fire: hose down the chassis to cool it enough for someone in bunker gear to cut into the battery compartment, puncture the battery compartment in several places to create a corridor through it (so steam can escape without building up pressure) while water continues to be sprayed to keep it cool enough for them to work, then insert a hose directly into the battery compartment and keep a steady flow of water for several hours until the batteries have discharged and cooled below their ignition point. Turns out lithium car batteries are a lot less reactive than previously thought and you just have to cool them off and get all the stored charge out of them which is a lot faster and uses less water than was previously believed (previous methods were things like "drop the entire vehicle into a modified shipping container full of water and leave it there for two days"), and if done quickly can mean most of the cells inside the compartment never even ignite in the first place.

I saw a video of a fire department testing and comparing different approaches a couple of months ago, and it was very interesting in a "dry recording of raw data" sort of way.

This had me curious enough to do the napkin math

A single water bomber has about 6,140kg of water/suppressant payload. A single heavy-lift cargo hexacopter drone has a payload capacity of 8.7kg

It would take 706 drones to exceed one water bomber, but they would naturally be far more spread out and thus far less effective. There is at least 4 water bombers I've seen deployed to California, so at 2,800+ drones, it would be one of the single largest drone performances ever and probably about as effective as pissing on it

[–] GalaxyBrain@hexbear.net 19 points 4 months ago (1 children)

I guess you could remote pilot a water bomber and call it a drone but that seems pointless. With multiple drones using that little water the heat from the fire would evaporate I would guess all of it. You'd get a nice steam cloud at best. Probably fuck up a lot of drones in the process what with the heat they're flying over and all that steam, neither are great for electronics that aren't nearly as well protected as on a damn plane and also on a plane aren't absolutely essential, at least the plane becomes a glider

[–] barrbaric@hexbear.net 42 points 4 months ago (2 children)

No no that's just a plane, we need a bunch of drones capable of carrying 2 cups of water each all controlled by some AI bullshit in a datacenter that is currently on fire.

[–] gay_king_prince_charles@hexbear.net 44 points 4 months ago (3 children)

They had 747s to dump water (not technically water but I'm calling it water to avoid waltzing around the slur filter) to carry 70,000 liters of water to fight fires. I'd be shocked if a single drone could even carry 1 liter of water. They don't have these anymore because the 747 was owned by a private company who went under and sold it to an airline.

I'm not 100%, but I'm fairly sure you're allowed to bypass the slur filter in situations where it throws false positives.

Some quick searching shows that the heavy duty cargo drones top out at about 480 lbs of payload. At 8.33 lbs per gallon, 480 lbs of water is about 57 gallons. According the Wikipedia the smaller end of aerial firefighting planes hold about 800 gallons. So you’d need 15-16 of the most heavy-duty drones to match the output of one plane, and of course it’s simpler and quicker to refill one large tank than fiddling with 16 smaller ones.

The thing that would probably get cheaper is pilot costs. At least here, a pilots licence is about 200 times a commercial drone licence, and I assume insurance costs would come down due to not actually putting people in the air.

There's also an advantage to having more eyes in the sky to spot smaller fires breaking out, and potentially putting them out with a smaller payload.

I can see it having its uses, but the main use would be selling drones.

Just use a train except now its a plane.

[–] Torenico@hexbear.net 17 points 4 months ago

Alright I got an idea. See those FPV drones used in Ukraine? Same principle but instead of strapping an old RPG-7 warhead to it we put small water balloons and then we smash the drone into the fire. That'll work out just fine.

Everything but solving the core issues plz

[–] GenXen@hexbear.net 15 points 4 months ago

A device that's little more than a lithium-ion battery, a water tank and propellers. Nothing bad could possibly happen if the first two somehow came into contact with one another.
