I’ve always thought a stupidly expensive but cool and helpful device would be a tabletop mosquito/fly/wasp killer that shot lasers at said insects. I’m very happy to see there is an underwater version that seems to be really effective

They exist in trials. The human danger is too great though I think. If the laser thinks your eye is a fly for a split second, game over for vision.

A laser that can kill a fly in the fraction of a second has to deliver enough energy to fry your retina even though a dozen sunglasses. Also consider that the laser is focused down by the lens in your eye which greatly amplifies its power.

That's not how specific wavelength safety goggles work. You can get both near UV blue light 440nm 5 watt goggles, and infrared depending on the laser.

Problem is they tend to shift the color of light for everything so much that they aren't pleasant to wear for a long time.

My worry would be getting hit on the skin, a 5 watt 440nm laser hurts, and it's a deep burning pain that doesn't go away.

Why even pretend my reply was about safety goggles? Obviously a huge difference vs regular sunglasses.

yeah well I'll just wear two dozen sunglasses. that'll make me twenty four times as cool as you, Mir Science Man.

So many ways to engineer out that hazard.

Last I understood was it's been patented 10 different ways from Sunday, and prototypes are just sitting on shelves, collection dust.

So now the fish are lice free, but blind? D'oh!

I think it wouldn't be a device to have on passively. Just something to turn on when you need it, like a vacuum. So you can just put safety glasses first.

LOL, $600 for something that is unproven and has a high chance of being just a scam?

Shhhhhh. I'm sure it will be a legit as StarCitizen!

Hey at least SC has a playable demo that's occasionally fun to play (I got a free code with a piece of computer hardware a while back and haven't spent a penny on the game otherwise)

2

Neat! Though I’ll probably wait until people say it works well and doesn’t accidentally burn out your retina

Can you image what kind of cult these fish will create?

Haha, that is such a cool use for laser technology and also the fish look like they are clubbing. Thanks fo sharing :)

Fish farms are one of the most 'boring dystopia'-moments in existence. They are bad for the environment, breeding disease like it is their main job, they are cruel as fuck (imagine factory farming could layer their animals on top of each other) and most fish end up dead. It is funny how people instantly close their eyes when we are barbaric as fuck towards "food"-animals, like they do have no place on this planet but on our plates. The same disgusting mindset that has let us to another mass extinction.

That's an antiquated reality. It should be a mRNA vaccine or perhaps some kind of nanobot that kills these parasites.

That’s not cyberpunk though, more solar punk imo.

Cyberpunk is all about unideal but pretty optimal solutions.

I was thinking of Sterling's Shaper/Mechanist universe, with the conflict being between genetic tinkerers and techno-upgraders.

You could blast the parasites with lasers on drones. Or engineer better fish immune systems.

Bio punk?

Seems to be something unrelated to this here. That system could never target such tiny organism, let alone have and impact at the flow speed. These fish are also not any of their hosts.

Oh totally, wasnt saying they were the same. was just adding an interesting thing to the discussion.

2

flatforms, and thier eggs ar epretty microscopic, the lasers would be ineffective here. best not to swim in places where the flatworm exists.

1

it seems like a human created problem int eh first place too. when you farm salmon you have to do it in enclosed area, so this unnaturally density of the amount of fish per area is quite high, and parasites, and infections are spread quite easily. Alantic salmon is usually the only ones that can be farmed, other salmon species are much more difficult. wont affect parasites like parasitic cnidarians.

Why is it I go straight to “some fascist government is going to set this up on the street and just laser undesirables”

Except it clears acne and keeps people clean-shaven. Unfortunately ​it doesn't work for some minority subset due to skin, hair color, or some other overlooked bias. Ultimately leading those individuals to fail job interviews and such. Leading them to a life of meager success compared to the majority.

Given that the (Norwegian) Fish Farms on the coast of BC almost annihilated the natural salmon due to the lice and other ecosystem damage, something to destroy the lice might be a little bit helpful. Although it might only be helpful to the penned fish and not the surrounding environment.

15

Awesome, but it's hard to imagine what this must seem like from the perspective of the fish.

we aren't reading our writing latin so we don't need to follow latin rules for tenses that don't exist in English

Hopefully it would mitigate the spread into wild populations.

As a pioneer in the use of Artificial Intelligence (AI), blockchain and laser technologies, Kvarøy has emerged as an industry leader in sustainable fish farming.

bingo!

MFW people invent laser weapons to shoot parasites off penned animals instead of just not eating fish.

Hey man can't just go around and tell people to not kill unnecessarily. Nobody like being called out, even if true. That is like really not nice and stuff.

Environment will be saved by capitalism, finding new, and good ways to exploit life on earth 👍 (/s)
