Okay, not a scientist, but doing a writing project that requires a little knowledge. My question is: If there's a constant source generating enough energy into running water (like a stream, surrounded by non-conductive material) could the water carry an electrical current for an indefinite period? Basically, doing the same job as a wire.
I think the conductors in the water (minerals) may deplete over time because of chemical reactions to this process...but if it's a running stream with constantly renewed minerals, could this happen?
Edit: Clarification was requested for a couple parts. 1) Method of conduction to the water: Not that important, really. I guess a wire capable of conducting the necessary amount of power could work. 2) How fast the water flows: I'm not sure. A strong currant, I guess. But not as severe as rapids.
