Unlike turbine-powered planes, the aircraft does not depend on fossil fuels to fly. And unlike propeller-driven drones, the new design is completely silent.
I suspect that the design is silent due to its low power and that something with enough thrust to perform some useful task would be louder even if the noise is that of wind only.

- tqkxzugoaupvwqr 4y agoIt’s extremely loud, something I didn’t expect, and sounds very much like a high speed fan. Together with the black box it made me suspicious if we aren’t being deceived. Two comments under the article think the same.
