Hi Alfred,
Water caps. are excellent for some applications however,
in resonant ckts. the power factor of a cap. =1 ---- that means that
a dielectric of 80 , though it sounds great--- will absorb
about 80% of the energy of the system via dielectric heating.
I think this reasonably correct --- however I have seen
a water cap. mfg. by a Japanese firm (natch) used in
pulsed laser applications --- i dunno how -- but they did it.
You might experiment though --- at least a quickie
water heater for coffee ? :>)

Is distilled water considered to be a viable dielectric material for a
plate capacitor? High voltage vs. low voltage? DC vs. RF? Since it's k=80+
it would seem to be a good choice. As a toolmaker, I would have no problem
making a sealed, watertight plexiglas cube, void of air, with evenly spaced
copper plates inside, and I would like to do this if someone doesn't tell me
it is a dumb idea.
What is water's dielectic strength? I did a search on the internet for
this value and the only thing I kept finding was it's dielectric constant.
