That's rather brilliant Dana.

I contracted with an FM station that had it's transmitter atop a 500 foot
rock. Even worse, there was only single phase power available with a
Phasemaster to run the BE FM-30. The rig was constantly blowing out 
rectifier
stacks, solid state relays, etc. I took an old portable AM radio and 
disabled
its local oscillator, essentially converting it into a 455 kHz AM receiver.
The audio output drove a comparator and integrator that was hooked up to 
their
generator. This jury rigged setup could detect big thunderstorms 25 miles
away.  It would turn on the generator and transfer the load until two hours
after the static went away. Once this went in the outages at this site 
simply
stopped...

There is indeed current flowing. I know of one system where those currents
were
used to pre-start a generator so the plant was on standby power before a 
storm

affected the power grid.
