…Was invented by me today while we ate our supper with the patio doors wide open to admit the glorious sunshine. Unfortunately we also admitted an insanely persistent fly. Somebody really needs to miniaturise yet further a quadrotor, equip it with a little vacuum cleaner sucky mouth and an incinerator inside, fix it up to a remote control system with a joystick and send it out like a tiny hawk to swoop upon the critters and suck them to their fiery doom, preferably with a satisfying actinic flash and a buzz like the noise a lightsabre makes in Star Wars. As a by- product, the chemicals harvested from the flies’ little frazzled bodies could power the “predator drone”, as I think I might call it, unless that name is taken.
This would not be an efficient means of killing flies, nor even of using quadrotors to kill flies. To do that you would have to give the quadrotors echolocation and probably rejig them as Von Neumann machines. Inevitably they would start to evolve independently and develop a taste for human flesh, so perhaps we should stick with having a human at the controls. In future years, when the cry of tally-ho is a familiar refrain at every barbecue and picnic, raise a glass to me and send me some money.
Only it would not actually be a blood sport. Insects do not have blood, they have something called hemolymph sloshing about inside them instead. Not ichor, that was Greek gods and other sundry immortals. Hunting Greek gods with quadrotors doesn’t work, ‘cos they’re immortal.
