The main things that annoy me most about my beaten up old car are that the fan doesn't work, and the windscreen wipers make an absolute racket. But if patents filed by McLaren are anything to go by, windscreen wipers will soon be a thing of the past as they look to replace the pesky things with scientific magic.
Alright, it's not really magic, but no-one would blame you for thinking it was. McLaren is apparently planning on using ultrasonic vibrations to create waves that would carry the water off your windscreen. Pretty damn magical if you ask me.
That's not everything though, using a combination of ultrasonic pulses and the resulting heat, this system could theoretically remove dirt and even snow from your windscreen -- sounds like the days of sitting in your car waiting for it thaw out will be a thing of the past too then.
There is no indication when this wondrous technology will be made commercially available, but if it works I can't see it taking too long. [Gizmag]
