Technically, pure water is not a good conductor. More of a dielectric
insulator. Its when you get those nasty impurities and ions in it,
that it becomes an ok conductor. Since its such a good solvent, its
rather hard to keep those nasty ions out.
As far as I remember, one of the hardest parts of dealing with cooling
liquids are the impurity buildup issues. Unless you are dealing with
Flourinert (see www.sisweb.com/referenc/msds/fc70.pdf ) which is
goodness embodied ... unless you burn it ... then its pure eeeevuuulll.
