Recent innovation could eliminate windshield wipers


A recent innovation has excited some in the car design business — a move that could see the end to windshield wipers.





Apparently, using “nanotechnology,” Italian car designers have come up with a self-clearing windshield.





It uses a special oxide to repel water and miniature nozzles that blast out water and air to get rid of dust and dirt.





The windshield uses super-thin layers of nanoparticles on top of the windscreen. Each layer is a couple atoms thick, meaning they can work simultaneously on water and dust.





And it does appear an attractive idea — after all, even the best windshield wipers don’t reach the whole screen, which means drivers have to put up with a permanent “film” that restricts vision at the extreme edges of the glass area.





Windshield wipers also get frozen to the glass overnight in winter — a common cause of calls for emergency service, when fuses blow as a result of drivers starting the car without first freeing up the wipers.





Whether the new wiper-free technology could cope with Canadian road salt and grime has yet to be seen.





It’s certainly been a while since windscreen wipers were on the drawing board: In 1969, the first intermittent wipers were introduced.





A year later, Swedish car manufacturer Saab introduced headlight wipers.
