[–] bufalo1973@lemmy.ml 27 points 2 years ago (5 children) If you fire a laser against a mirror, it bounces but raises the heat of the mirror so you end up melting the mirror and destroying the drone. permalink fedilink source hideshow 10 child comments replies: [–] skulblaka@startrek.website 25 points 2 years ago I 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. permalink fedilink source parent [–] nuke@sh.itjust.works 22 points 2 years ago* (last edited 2 years ago) permalink fedilink source parent [–] CanadaPlus@lemmy.sdf.org 10 points 2 years ago Depending 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. permalink fedilink source parent [–] BigMikeInAustin@lemmy.world 9 points 2 years ago (1 child) But the drone stays in the air by making wind, which would cool down the mirror? permalink fedilink source parent hideshow 2 child comments replies: [–] CanadaPlus@lemmy.sdf.org 4 points 2 years ago* (last edited 2 years ago) (1 child) Unironically yes.
