AND essentially all oils are more or less flammable.
Except 'PCB's', which have their own problems.

It needs to be VERY well purified AND KEPT that way.
Non trivial tasks. And its more 'corrosive' than
most oils. 99.99999% pure.
(Near here: Some of my power comes from a HVDC
substation, that chops +/- 500KVDC to 60 Hz. They
do all the HVDC with 99.99999 water.... They have
Substantial Plant to keep it pure.)

Free, self healing, good dielectric strength.
Oil scares me from being flammable, tho many people
use it. I Have my doubts water can be kept
