If you've ever spent a few hours sifting through the Internet for that perfect fighter jet wallpaper, you may have noticed a little something missing from the average cockpit: windshield wipers. Your run-of-the-mill wiper blade might not function properly at super-sonic speeds, but that raises the question of just what the military does use to get raindrops and smooshed insects off of its windshields. Supercar maker McLaren recently became privy to the tech behind the military's spotless windshields, and they're not wasting any time slapping it onto their vehicles.
The secret to a spotless windshield, as it turns out, isn't some water-wicking coating or a good old-fashioned spit shine. It's hypersonic shielding, and we're not being told exactly how it works just yet. What we do know is that nothing — be it water, mud or even squished insects — can stick to a windshield equipped with this tech. What's more, unlike regular windshield wipers, the hyper-wiper (technically, nobody is calling it that) is always on.
One way that McLaren's nascent wiper-less windshields could work is by attaching a hypersonic transducer to the corner of the glass, says one expert. This would theoretically vibrate anything off of the windshield the instant it attaches.
McLaren is planning on implementing the tech on its entire line of cars by 2015. The rest of us will have to wait a little longer, but once a consumer product is perfected, we might all be able to pick up this once-classified tech for as little as $15.
