The wiper system is one feature that hasn’t changed much in vehicles. But nanotechnology has a solution to get rid of it completely. An Italian designer named Leonardo Fioravanti has designed a car prototype featuring a windshield that removes water and dirt without the need of a wiper. His idea is to take the modern windshield’s features (mainly, laminated safety glass made out of two sheets of glass with a plastic layer in between), and add nanotech properties to it and then activating the system through an electric currency.

In the prototype, four sheets of nanotech-enabled sheets are grouped together, alternately filtering the sun and repelling water (the function of the exposed sheet of glass), moving the dirt to the sides of the windshield (through a magical-sounding nano-dust film), which is then activated by a third protective conduit layer, and is finally powered by a conduct of electricity in a fourth layer that makes the whole thing work.
