Using the same technology as “bladeless” fans, I would think these drones would be both safer for things they might run into and less prone to crash if they do bump into things … but will the cost make sense?
Originally shared by +Thomas Frey:
Will bladeless drones overtake the industry? Very clean design, and safer on several levels, but it will need to be operationally and functionally cheaper and more efficient.

The Bladeless Drone is aptly named for its brilliant design that ditches dangerous blades for air ducts. The resulting unit is not only safer but so quiet

I don't see cost as a deal-breaker, especially of they can be mass produced. In fact, small ones might not be much more expensive than conventional quadcopters. The question is, can they provide the efficiency and thrust necessary.
I have a Dyson fan. It’s very nice, but costs 10 times as much as a good bladed equivalent. That could well be a deal-breaker. The issue of bladed drones bumping into things can be dealt with simply by shrouding the blades.
@David – Good point. That cost differential is the biggest issue, clearly.
It doesn't matter if it'll become commercially viable – I now have a visual model for the hovercraft used by Vyortovia in our Masks game.
