3D-printed sound-powered jet engines propel micro drones — fliers are completely silent; researchers use ultrasonic frequencies to drive 12,000-RPM silent hovering fliers
 3D-printed sound-powered jet engines propel micro drones — fliers are completely silent; researchers use ultrasonic frequencies to drive 12,000-RPM silent hovering fliers

A specially shaped 3D-printed resonator can make air shoot out of its nozzle and provide thrust when it hit with the proper frequency. While the prototypes don’t deliver practical levels of thrust yet, they show proof that the concept works.
