It's been known that electrical pulses can deice for years.

Petrenko's physics are a bit off. First of all a current does not create
an electrostatic force, static charge does. A current (time rate of change
of charge density wrt individual charges) creates a magnetic field and an
electric field in the direction of the current, opposite to the applied
field to the conductor that makes the current move in the first place. I'd
love to see how protons get any mobility to act as charge carriers. You
see, protons are held within the atomic nucleus by nuclear forces. To get
them free, the atom must be split. In semiconductor physics it's either
electrons or holes that do the charge transfer. I could see positrons
doing some movement, but how in a proton driven through a crystal lattice
such as ice or a wire? What happens when the protons get to the battery?
The protons could move about if the water molecule was a plasma. Here's
something similar, but a bit more developed and much more useful:

It's well known physics that high density current pulses with cause
conductors to flex. The audio cable on the SQS-26 sonar on the Knox Class
FF moved 4 inches with every pulse. I think the ice deflects due to the
reaction of the current with its own magnetic field and the presence of
the required conducting sheet. There's probably some thermal heating too.

I thought thermal heating would be a part of the process, but shedding
within 2 or 3 seconds?
