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!
