Flying fan vehicle will appear

Gregory Benford : science fiction author and astrophysicist
The “flying fan” vehicles of the future will be easier to fly than helicopters, and should cost a lot less. A rough guess is that in about 10 years you’ll be able to buy a four-place fan for the price of a good car
A new kind of flying machine is being designed that sounds like the answer to your desires for a personal aerial vehicle. It is almost like a flying carpet. A good name for it might be the “flying fan.” It uses the principle of the ducted fan, the same idea that is used by the flying platform
