...-- We could run a water-wheel using the water that leaks out of
the hole, and have a nice perpetual-motion machine.
In particular, repeat the experiment with liquid helium
instead of water. Cool it to a few millikelvin. Dielectric
effects will be essentially independent of temperature over
a wide range.
Intuition confronts the second law. One punches a hole in the wall of an open
vessel filled with water and expects the water to come out, but the water does
not come out because the the second law says no.
I see no reason to think the 2nd law is involved.
Didn't you say "perpetual motion machine" above?
Mythology people are afraid of. "Perpetuum mobile of the second kind"
... the second law is not even defined properly.
