Who would have thought that the age old tradition of hacking at a windshield with a piece of plastic would soon be on its path out ? Dartmouth prof Victor Petrenko has plan PETD — beat electrothermal de - icing . This thin motion picture can completely solve a windscreen in a second . It is already being use in Sweden to cover the Uddevalla Bridge to prevent frost over . PETD can also work in reverse by create better bonds between ice an open , great for snowboarders or skier .
It works by breaking the first two Bond between the crank and whatever surface it is on . An electrical charge is used to heat up a micron layer of the surface breaking the bond , then the resulting water acts as a lubricant and all of the Methedrine slide away .
