In Norway, laser weapons are being used to remove sea lice from farmed salmon. The Stingray Laser System uses cameras to scan the fish, identify lice, and then deliver a laser pulse to kill them.

    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.

                I thought it was obvious I meant laser safety glasses.

        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.

        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.

            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)

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