minus-square@[email protected]linkfedilinkEnglish9•1 year agoBut the drone stays in the air by making wind, which would cool down the mirror?
minus-square@[email protected]linkfedilinkEnglish4•edit-21 year agoUnironically yes. If that’s not enough, add water.
minus-square@[email protected]linkfedilinkEnglish3•1 year agoA laser attack during a hurricane would really surprise the target.
minus-square@[email protected]linkfedilinkEnglish2•1 year agoDo not point laser at remaining eyewall.
minus-square@[email protected]linkfedilinkEnglish25•1 year agoI may risk being too credible here, but a $80 drone is a lot more expendable than a $40m laser tank. The drone can be considered a consumable. Hell, mark the drones down as ammo.

minus-square@[email protected]linkfedilinkEnglish8•1 year agoIn all seriousness, wavelength-specific dielectric mirrors can approach six nines of reflectivity. The hard part is hitting the mirror instead of the drone.
minus-squarethreelonmusketeerslinkfedilinkEnglish3•1 year agoJust make the mirror as wide as the drone! Oh, wait…
minus-square@[email protected]linkfedilinkEnglish3•1 year agoYeah I guess you can’t pulse-ablate a mirror made of plastic. Though it invites a backup strategy of spraying your enemies with molten drone.
minus-square@[email protected]linkfedilinkEnglish10•1 year agoDepending on how long you do it, how powerful the laser, and how quickly it can cool off at the same time. And like the other guy said, you can make really good mirrors if you only care about one wavelength.

And keeping the mirror surface clean
