As I understand them, they are mostly current driven, moreso than
voltage....that is why I mentioned Stubblefield in the same post, since
it was claimed his entire farm was lit up at night with carbon-arc lamps
fed from earth currents....known as 'earth batteries'.
They are not simply batteries, because the circuit pulls power from
the earth which never runs down....there were several patents pre-1900
which dealt with these...including Stubblefield.
I know a couple of guys who said they have spools of wire that are up to
1 mile...this wouldn't have to be 10 gauge Romex....it should work with
16 or 18 gauge...
I am wondering whether it should be solid core (common in the 1800s) or
stranded....I can't see where there would be a difference except for
resistive heating from the wire itself...but then again, that depends on
the load...this is from the offgrid file in the energy section;
It is important to use extension cords of adequate current carrying
capacity when utilizing a generator to operate portable electric
tools. Undersized cords result in excessive voltage drops and
additional power plant loading. This also causes excessive heating
of the portable tool because voltage drop reduces tool capacity.
