"When exposed to a high-voltage electric field, water in two beakers
climbs out of the beakers and crosses empty space to meet, forming the
water bridge.

One can't build a perpetual motion machine using this
phenomenon. Energy is used up by the resistance of the water to
electric current. There is an electric current passing through the
water. The water is heating up in the bridge and in both beakers of
water. It heats until the bridge collapses.
According to your false logic, every electric motor violates the
second law of thermodynamics. One places an electric field on the
wires, and the motor does work. However, electric motors don't violate
the law of thermodynamics.
The transformation of the water from a beaker into a bridge is
caused by work, not heat. No heat was conducted in this experiment.
The electric field was generated by a power supply. The electric field
pushes electric charges. When an electric field pushes electric
charges, there is a transfer of energy called work.
Heat is energy that is transferred due to a difference in
temperature. The energy did not go into the water because of a
difference of temperature. No difference in temperature was measured
between the beakers before or after the experiment.
Perhaps you can help the scientific community understand as
follows. Explain where the heat is flowing when the water bridge
forms. Describe the apparatus, and tell us what the temperature
distribution was like in the apparatus. Point out to us the high
temperature and low temperature parts of the set up. The explain to us
how heat was transferred from a low to high temperature reservoir
without any other change in the system.
The second law: A closed system can not transfer heat from a low
temperature reservoir to a high temperature reservoir without
changing in the system.
So where are the low and high temperature reservoirs !-)
