Yes, it has been done... and it has some very interesting real world uses: http://www.theregister.co.uk/2014/07/03/tinfoil_hatters_spook_says_nsa_can_track_whistleblowers_through_power_lines/
----------------- If we all did this, then I realize that we could identify the different power grids. However, I wonder if there is any interesting variation *within* a grid. As the electricity flows vary throughout the day, it seems possible that the phase difference between two people on the same grid would actually change (a bit). Has anybody done this experiment? _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
