Yes! ... and that brings to mind an old thought that I never fully
explored.
Water has a dielectric constant of about 80! I don't know the
dissipation constant or loss factor.
It seems, on the surface, that one could dip a small air variable in
(pure) water and have a high voltage part with 80x the capacity of the
original.
For long term usage the assembly would necessarily have to be sealed
and the plates would likely have to be fabricated from gold or platinum
but, they would be so small that might not be a limiting factor.
Now, I've never heard of this being done... Is there something I've
overlooked?
