Electric power plants use pure, distilled, H2O to cool their generators.
*If that water conducted electricity, it would short out the generators.
At least, that's what my electrical engineer buddy who works for the 3rd
largest power supplier in the US tells me.


Our nuclear power plants use " heavy water " for that very reason -
so that gravity will assure that the short-circuit-current
will flow to ground .. With regular old tap water -
the electrons might go anywhere !
