It's an insulated wire, and twice as costly if I send two wires.
If the ground has this kind of bulk resistivity

it does seem impractical.
But it seems to me they used to send telegraph signals with only one wire.
Single-wire earth return - Wikipedia, the free encyclopedia
I'll have to run some experiments with a 50' extension cord, using 120 vac, possibly through an isolation xformer. With 25Ω earth resistance I should be able to substantially light a small bulb. Driving a ground rod at the receiving end is probably the hard part. Deeper rod = brighter bulb?
Never tried it.
and use the resistance of the ground for a return.
Anybody done this?
The destination is 750' away and I figured on using a ground rod at both the sending and receiving ends. I need about 400w at the receiving end.
be sensible
I think he is still in the planning stages. Initial estimates for a code compliant installation is about one kilobuck.Why didn't he ask us himself?
Prolly didn't know about this forum.
So he ran the one wire already... For what?
