Ah yes, the "star wars laser defense mosquito system". It' as impractical then (early 00's origin) as it is now https://www.youtube.com/watch?v=TGkPMZxWPpA&t=2s (it's Dutch but you get it). Unless you can get mm accuracy and perfect non-foe detection it's useless with the multi-watt lasers generally required.

In a flat area, you could imagine designing a system so that it couldn't aim below horizon, and then mount it 10-15 feet up to mitigate the risk of blinding.
That sounds like a big risk to aircraft.

You might be able to create a vortex cannon with enough shear force to rip their wings off.

I've been dreaming about that to kill mosquitoes since I was a teenager. Then I wondered: "how to prevent firing the laser into someone's eye?" and my idea was to only shoot laser from 2 meters high and to only ever shoot towards the ceiling, never downwards, while having the ceiling having some kind of paint/material that wouldn't be reflecting the laser too much. Make the paint/material all white to makes mosquito…
Wipe them out, all of them. The ecosystem will survive mosquitoes' extinction. On the subject of laser safety, can you make one weak enough that a human will naturally blink or look away without getting blinded but powerful enough that it'll overheat the mosquito its trained on for a few seconds? If the Joules are spread out linearly over a few second, I expect it'd exponentially decrease the risk of chance reflectio…

There are a number of DIY instructions for building a phased array ultrasonic manipulator, eg [1]. You might be able to 'tweeze' the offender into a capture apparatus or high voltage deanimator. https://hackaday.com/2021/08/18/phased-array-levitation-is-s...
Why not the same idea with lasers, if you have an array of low power lasers but they all focus on one 3D location, if you are not at the focus location you will not be exposed to a dangerous laser power. An array of hundred to a thousand low end laser diodes using a an array of mems mirrors to aim the beams will ensure the focus point will fry the bug.
Or 200W xD

#96This sounds very similar to that old idea for protecting African families from female Aedes Aegypti mosquitoes[0]. I think the idea never took off, and I’m still not sure why. [0]: https://youtu.be/hqKafI7Amd8

Reminds me of the Chinese's brutally misguided attempts to stave off the famines during the Cultural Revolution. One of their worst ideas was to eradicate sparrows, thinking that sparrows were eating crops. No, sparrows were eating insects that were eating crops. So with sparrows gone, the insect population exploded, resulting in even worse destruction.
Just a reminder that when it comes to ecosystems, we really don't know what the fuck we are doing. There are hundreds of similar stories, e.g. destruction of wolves, bison, pigeons, and other organisms we consider "pests". It's a wonder that the worldwide ecosystem doesn't consider us the pests.

That’s not how reflections work. Also there’s no bug as big as a coin that such a system could/should kill, so it’s pretty easy to not misdetect that. Again, corners have a higher probability of ending up in your eye than even just someone flipping a coin in 2022.
The comment said your system has a bug as in it malfunctions and decides to shoot the coin anyways, and his other point was you will be looking at the coin wide eyed so perfect chance for a reflected laser to hit you in the eye if by chance the correct angle happens to line up and send it back to your eye. Also, I've seen too much unbelievable stuff actually happen so nothing is unbelievable in 2022. Yes we are talki…
Leave your bubble, I’m talking about relative probability, I’m not saying that it’s “impossible.” We accept far greater risks in our daily life than this.

#99It says the prediction is accurate to 1.4cm, but it doesn’t say at what range. 1.4cm at 1km is great, but 1.4cm at 1m likely isn’t usable. I’m also curious what the failsafes are like for this - how will they prevent laser spillover or misfires from hitting eyes? Even if this is a 1 in a million chance, it likely isn’t worth it except in highly remote areas.

Right, because nothing else we already use has any chance of causing permanent damage. Nothing at all. Leave your bubble, I’m talking about relative probability, I’m not saying that it’s “impossible.” We accept far greater risks in our daily life than this.
