Okay, I keep wondering, what constitutes a “wireless device”?

Is it a device advertised as being wireless?

Is it an electric device that can operate off the grid?

Is there a maximum size?

Is an electric car or cruise ship large enough to be considered “”“wired”“”?

Does it have to be electric, or is it any system that is affected by external forces without a physical connection?

Is the earth wireless? If so, does the wire connect to anything or is it just kinda floating in space? Can we use it to build a space elevator?
