You could use gravity to fill the tubes up again with fluid when voltage is removed?
Or use an other compressed tube to push fluid into the empty one that has now voltage removed
Building up the voltages takes energy.

But now, as to that mystery
electron orbiting an atomic core, what keeps it going?
Charge attraction,
right distance and speed keeps it in orbit.
you can say an object in space that is at the right distance and speed from a planet is in an eternal fall.
gravity keeps it in orbit 
But there is a similarity there,
is this the same force in an other form.
Just a thought experiment
Our Jeroen from CERN man has referred to a paper that has the whole universe filled with fluid
the math seems to work out it says.

Drifting from subject a bit...
There is a lot of fun in fishicks
