McLaren to replace windshield wipers with a force field of sound waves
J Thoendell stashed this in Cars
Frank Stephenson is McLaren’s chief designer and has hinted at a new system to replace the wipers. It is thought to involve using ultrasound to send 30kHz waves across the windshield, which would keep it clear of any debris, even those really horrible insect remains that can build up and obstruct your view.
How does it stop such debris? By creating a force field that stops rain, snow, or insects ever reaching the windshield. If they can’t touch it, then the glass will remain clean and clear.
