The Hidra concept car doesn't need windshield wipers. Fioravanti

Pininfarina automotive designer Leonardo Fioravanti's Hidra concept car uses windshields that repel water and dirt, doing away with the need for wipers. The nanotechnology-based windshield has four layers, with the titanium oxide top layer designed to quickly repel water. A second layer pushes dirt off to its sides, keeping the windshield clean. A third layer works as a sensor, while the fourth layer is charged with electricity to run the whole apparatus. An article describing the technology and concept car appeared in the Italian publication, la Repubblica, and can be read in English here, thanks to the magic of Google.
