Leonardo Fioravanti of the awesome vehicle design house, Pininfarina has put together a prototype car, called Hidra, which has a windshield that negates the necessity for conventional wipers. The design relies on aerodynamics and surface treatment alone, which will supposedly be enough to keep a fly-away tree branch from obscuring your line of vision. The chemical treatments applied are where the autonomous cleaning action really happens, and they actually sound quite interesting.
The car uses a special aerodynamic design along with four sophisticated surface treatments to the windshield to keep the driver’s view clear. The first treatment filters the sun and repels water. The second is made of nano-dust which is able to push dirt to the edges of the glass. This dust is activated by the third layer, which senses dirt and activates the second layer as necessary. Finally, it’s all topped off by the fourth layer which is a conductor of electricity to power the whole mechanism.
