Those blades are crazy tough and the battery is the least of your worries when ingesting a drone.

Many turbines spend time with their blades locked because the wind is too strong - they would turn too fast for their gearbox to handle.

With handcrafted blades, a nontrivial number get chipped or tipped within the first few uses, at no fault of the user.

If a drone the size of the one in the 60 minutes demo hit helicopter blades you'd probably be looking at fatalities.

Apropos of nothing, Muji's USB desktop fan has contra-rotating blades and is amazingly quiet for the amount of air it can shift.

You could feather the blades, but at least in the markets I've worked in they never would.

"But the industry sure wants to convince us that scalability is the most important property of infrastructure, because then they can sell us complicated tech we don't need and support contracts to help us use it." And lets not forget: replace any and all efforts at code optimization with "just throw another rack of blades at it".

Blades at almost supersonic speed will slice everything like a butter.
