When will BMW have this - Fighter jet technology to replace windshield wipers
As far has today's high tech cars go, their windshield wipers are still pretty low tech. Motor driven arm with rubber, or rubber-like squeegee to clear debris from the windscreen. No huge leap from when they were introduced in 1903, by inventor Mary Anderson. Much better than sticking your head out the window though. Changes blade and arm design, to keep the wiper down at higher speeds, have helped wipers work better over the years. Still, On episodes of Top Gear, you see them get rendered useless at the speeds of today's supercars. A big change is coming, I can feel it.
Enter McLaren. In a recent interview, McLaren's' chief designer, Frank Stephenson, said McLaren is developing a new wiper system that uses a force field of high-frequency sound waves, to repel debris from the windscreen. Now that sounds like a step forward. Not too many details were given, but , 'an ultrasonic transducer on the screen could send 30 kHz waves of ultrasound across the surface and repel all debris--even snow and insects.' Such systems were originally created by the military for use on fighter jets. Finally, supercar meets its much needed super wiper.
There has been no word as to when this system would make its way to one of McLaren's cars. Maybe others car makers like BMW will work on such technology. Personally, I'd like to see it.
