Are you somehow under the impression that just because it is “global” there are no transmitters and receivers and distance does not matter?

no. i don’t pretend to even begin to understand how the prototype at wardenclyffe was supposed to work. i do remember that it supposedly used the atmosphere as a transmission line, but whether that meant bouncing the signal off of it (meaning it was radio based) or somehow charging it (meaning it was static based) i couldn’t tell you.

I mean you absolutely can communicate from Australia to USA with nothing but an old rusty bed frame and 5 watts of power, so there’s that.
