The amazing thing about this gizmo is that it's reversible.
OK, I believe you can send an electric pulse thru a surface
film to melt ice, but to make it stick better?!?? That's
whacky. It's PFM.

Makes me wonder if you could make a variconductor film for
boat hulls that would not only prevent growth of fouling but
also 'repel' the water and make the boat move. Next step...
anti-gravity coatings!

If you engineered it you would be a billionaire....better get to work!

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?

It's possible if a force is generated. Sounds hokey to me though.
