Dyson, the maker of the first vacuum that does not lose suction, has created a fan that uses no blades. Here is a shot of one of the units:
Basically, this thing creates a column of air. No I have no idea how it works, but it does.
In my opinion, if the aircraft industry, and even those who have been trying to develop a flying car, get a hold of this technology it will revolutionize the industry.
I have been following the development of the Moller Skycar. Which has basically hit a wall due to development funds and the mixed reaction from the general public. One of the concerns that have been raised is how will the design handle the possibility of birds flying into the rotors. Well with this new technology that concern will go the way of the dodo, since there are no moving parts.
There are plenty of other roadblocks, which includes providing insurance for these vehicles, but I feel that this will be quickly remedied once the public gets more on board with these vehicles when they discover how convenient these units will be.
Really, who would not want to fly over the traffic than sit in it. This would cut commuting time considerably and create a great view on the way.
I predict this will turn the airplane industry on its head.
