Summary: more very low RF energy


The power grid makes a pretty good (and powerful) low frequency
transmitter.  A sizable fraction of what we pay for electricity
is 'lost' on transmission.  Just ask someone who lives close to
a high voltage transmission line about the effects of this RF
energy.  Another demonstration is to put your finger on the input
of an audio amplifier.

Does anyone know how far away you can be from any known source
of AC power and still be able to detect hum (middle of desert,
south pole, middle of the ocean, the shuttle, a screen room,
Gilroy, ...) ?

I suspect that this energy is detectable quite far from the Earth
as is a 10 HZ beat note between the two primary power grid 
frequencies.  Should we try and detect such transmissions from
other solar systems (Please, no flames for assuming intelligence
spawns AC power distribution systems) ?
