Interesting alternate form of propulsion. Bit like a Dyson desk fan I think. https://www.bbc.co.uk/news/av/technology-46310975/sci-fi-plane-with-no-moving-parts-flies-successfully

No, sorry, but nothing at all like the Dysan fan, which has LOADS of extremely conventional moving parts, from a bladed fan hidden in the "stand" to a brushless motor and axial fan blades inside the head. The Dysan is in some respects a magicians trick, new technology that really isn't, and is not anything like the scientific advance this technology offers. The problem with this new "drive" will be getting the power to weight ratio and where have we heard that before with electric flight?
