Next-Gen Windshield Wipers To Be Based On Jet Fighter "Forcefield" Tech 237
cartechboy writes "It looks like the old-school windshield wiper is about to be replaced by new technology — but not until 2015. British car-maker McLaren is apparently developing a new window cleaning system that is modeled from fighter jet tech. The company isn't revealing exactly how it will work, but the idea comes from the chief designer simply asking a military source why you don't see wipers on jets as they land. Experts expect McClaren to use constantly active, high-frequency sound waves outside the range of human hearing that will effectively create a force field across a car's windshield to repel water, ice insects and other debris. Similar sound waves are used by dentists to remove plaque from teeth."
