⁣Drone startup claims it flew its zero-emissions ion propulsion drone on 4.5-minute test flight

The drone, called Silent Ventus, uses proprietary technology to ionize the oxygen and nitrogen molecules in the surrounding air to create an "ionic wind" that propels the machine in the direction it wants to go. According to Undefined, the drone could be used for cargo.

According to Undefined, its "Air Tantrum" ionic propulsion technology produces up to 150 percent more thrust than current ion thruster technologies.

Earlier this year, the company released footage of a two-and-a-half-minute indoor flight test, saying the drone emitted 85 decibels of noise. Now, it claims it's flown a prototype for four and a half minutes, though it's only released one minute, 17 seconds of footage. The drone firm also says it achieved a noise level below 75 dB.
