My guess is that the base station will power many devices and be located such as routers are now. So, for instance, an office may have a base station that powers its employees' devices as they wander from room to room.

What about using it in the car? What about using it in a restaurant? A hotel room?

Are you really telling me that the Amazon base stations are going to be ubiquitous?

It's a bad design.

Just because it doesn't work in a car doesn't make it a bad design. Television doesn't work in most cars, but people still buy them.

Something doesn't have to solve every use case to be useful.

FWIW, I tend to agree with you. I think the better problem to solve would be to have electrical energy generative/storage devices. But I've been wrong about these things in the past so I try to second-guess myself.

Except this is meant to supplant a design that DOES work in the car, that's why it's stupid.
