Some of the ideas shown just would not fly. It is so easy these days for some kid to draw up his fan ...

Aloha Geebax,



You are right that a great many of them will not fly or ever fly and Vision VTOL is probably one of them. (I noticed the horizontal flight to.) But that half scale blimp has crashed already, so they are still learning the hard way. Those bigger designs have a better chance for success than the small ones like the Vision VTOL though because there are still significant energy density issues.



And NASA still comes up with some wild concepts! Blended wing designs are highly efficient and I really like those designs, but that white with yellow stripes Aether design has scale issues throughout. Scale issues can be fixed though and are more easily fixed in larger aircraft. That is why I said the folded or foldable winglets were a lost opportunity for efficiency.



Remember that guy with the red twin-rotary motors flying car? I wonder how far along he is now. Now that is old school! Definite energy density issues there though.



Aloha and Drone On!
