Drones that save power by hanging like bats and perching like birds

This Israeli company tried to do that with electric cars. It was a nice idea, but they lacked the capital and market influence to implement the in fracture at the scale needed to make it viable.

Car batteries are relatively large and heavy. But if I was going to try to implement that idea for something like drones or other human-portable electronics (which I wouldn’t, because I hate doing shit like that), I’d do something like a charging station for betteries that are checked out Airbnb style. Slot the depleted battery into the station and pull out a charged one.
