[sci.electronics] Free power from 'whispering wires'

This sounds like a typical urban legend. Whilst you can undoubtedly induce
a voltage in a coil placed near power lines, the voltage would only be a
few millivolts. You could not even light a bicycle lamp, let alone power
your house from it. After all, you are basically makinga transformer, but
the primary has one turn, the coils are yards apart, and the core is air
rather than iron. Altogether a very inefficient device.
  By the way, as far as I know, ALL normal power lines are AC.

This sounds like another person who has never been out on a farm where it
has been done.  Making a typical excuse with the caveat "urban legend".

So what? A.C. helps out.. the pulsations do that is.
