Tornyol's tiny autonomous drones hunt mosquitoes mid-air
YC-backed startup Tornyol just revealed an autonomous drone that uses ultrasonic sonar to track mosquito wingbeats and suck them into tiny propellers. Built by an ex-missile engineer, each drone covers up to five acres per charge. While a demo showed it intercepting a moth, proving it against tiny, erratic mosquitoes in the wild remains a challenge.
