I am unable to view this at work, but according to your description, this is
the historical water electricity experiment invented by Lord Kelvin more than
100 years ago. Its a classic experiment of electrostatics physics, and of
course it works with any conductive media, water is not required (but easiest
to do). The principle is charge separation.
A modern machine that uses the same principle is the pelletron made by NEC. It
is used as high voltage source for article accelerators.
