Propulsion with no moving parts!

This blew my mind. Completely silent propulsion. No hearing protection needed. Come on, @Pdwhite make an OpenPPG version with this :wink:

Haha ya I saw that pretty cool but would be so hard to make practical.

Give a lot more than a few more years my old fruit cake, and when they can start humping a meaningfull volume of ionised air to make something useful fly, well, how silent will it be then? And to all you Yanks and others out there โ€˜humpingโ€™ also means transporting/moving something.

Pretty good video on this tech: https://youtu.be/IorDYGI1uqc
