The Hidra concept car from Pininfarina automotive designer Leonardo Fioravanti will feature a windshield that repels both water and dirt, hence eliminating the need for wipers. This windshield was developed using nanotechnology, featuring a quartet of layers to help it do its job. The top layer is made out of titanium oxide that repels water quickly, while the second layer pushes dirt off to its sides, keeping the windshield clean. There is a sensor located in the third layer, while the fourth layer is powered by electricity to run the show. I say, won't it be pretty sucky if somebody breaks your windshield to get to that GPS system inside? It'd be a shame, since the replacement will probably cost you an arm, a leg and a kidney.
