Ever scraped ice from your car windows until your hands were stiff, cold and raw red? Or missed an appointment because it took so long for your window defroster to thaw through your ice-entombed windshield? Or had your lights, cable TV or telephone black out—and stay out for days—because an ice storm downeGood news: a group of researchers has developed technology designed to electronically zap ice off surfaces within in seconds. Unlike conventional windshield defrosters that rely on gradual warming to liquefy snow and ice, the IceController—created by Ice Engineering, LLC, in Lebanon, N.H.—delivers a swift (less than a second in some cases) jolt of high-power electricity that immediately melts ice at its interface with an object's surface. Once the bond between the ice and surface is broken, the ice slides away, says Victor Petrenko, Ice Engineering's chief technology officer and a professor of engineering at Dartmouth College's Thayer School of Engineering, where he invented the "electro-thermal pulse de-icing" technology behind the IceController.d power lines?
