Electric power plants use pure, distilled, H2O to cool their 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 !

I'm old enough to remember when there were HV transformers
that were cooled with get this - water !
Including my fav transformer cooling - on a EHV international
tie-line, no less - where the big old thang would get some extra
MVA with the cooling rads being sprayed with water - in addition
to the usual oil pumps and cooling fans ..
