Dartmouth College engineering professor Victor Petrenko… has devised a way to use a burst of electricity to remove ice caked on walls or windows. For surfaces coated with a special film, the jolt gets rid of ice in less than a second, far less time than it takes to hack at it with an ice scraper.
Look for this soon on everything from car windows to the wings of airplanes.
