on the possible chance the numerous
sides of law enforcement have a use for
better surveilliance I thought that a
recording device that sent out pulses of
data as variations on the pervasive ac
current hum would be much less
although I have minimal knowledge of
it feels as if any attempt to
detect radio transmission would screen
out this frequency as a result of all the
appliances that have circuits radiating
energy at typical ac frequency
a utility frequency location transmitter
undetectable unless you knew it was
going to give off primes at a precise but
||The bandwidth would be very low .... and the interference massive. But a code spreading technique might just work.
||Just use ethernet-over-mains - you could get full bandwidth motion video.
||The surveillance groups of the world can already reverse engineer the interference on your AC electricity to figure out what you have been seeing on your computer. Presumably it's a very small step from there to spotting your encrypted signal. so I doubt you'll be deterring anything but casual surveillance.
