    • + Wireless

    • - limited range

    • - horribly inefficient, increasing with distance

    So, there.

      tesla’s idea was global wireless power. no idea what his efficiency numbers were though.

        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. But not much more to do with that bit of non-ionising power.
