Nanotechnology-Powered Wiper-Less Windshield

Posted by ScuttleMonkey on Fri Feb 22, 2008 09:28 PM
from the plenty-of-room-at-the-bottom dept.
fab writes "Italian car designer Leonardo Fioravanti (who worked for Pininfarina for a number of years) has developed a car prototype without windshield wipers. This amazing technological feat is made possible thanks to the use of 4 layers of glass modified using nanotechnology. The first layer filters the sun and repels the water. The second layer, using 'nano-dust' is able to push dirt to the side. The third layer acts as a sensor that activates the second layer when it detects dirt, while the fourth layer is a conductor of electricity to power this complex mechanism. I haven't been able to find an English article, but there is always a google powered translation of the Italian article."

        Apparently they weren't expensive enough.

        Good point and funny reply, and this seems to be a good spot to reveal one of the great secrets of auto maintenance: you can sharpen your windshield wipers and make them last many times longer. All you need is a small piece of fine sandpaper. Get the wiper blade wet (if it's not already), fold the sandpaper into a V shape, and pull it along the edge a number of times. You want to take off the stiff and cracked edge and expose a fresh layer of rubber. I get extra years out of blades this way, though YMMV.

        I use a little gadget I bought at a flea market for a dime decades ago, a little piece of sheet aluminum that's mostly handle to hold an inch-long groove like two sides of an inside-out triangular file. Forget the "100 mile-per-gallon carburetor," it's the windshield wiper blade sharpener that's my candidate for great suppressed invention.

      Was there something terribly wrong with wipers to begin with?
      They inevitably wear out, lose curvature, smear, start squeaking, cause distraction, are a pain to replace, etc. Some more quickly than others. I bought a new car in September and realized a couple days later that I'd made a mistake going car shopping on a clear sunny day. The stock wipers work in such a fashion that after each pass, a thin film is left behind, evaporating a moment later unless the wipers are going fast enough (or the water's coming down hard enough) to prevent that. Fine during the day, or during heavy rain, but I almost had a wreck the first time I drove that car at night in a drizzle. The glare from streetlights and opposing traffic diffusing through the film left behind by the wipers made it almost impossible to see.

      I've been using Rain-X for years and as long as the application is fairly fresh, it's easy to drive in the rain without wipers. I have to say, if I could get a windshield with those repellent properties built in, and the effects were proven to last, I'd happily pay a premium for it.
      • Wow. Are you serious? I mean, "a pain to replace"? If you bought a new car, they should not be a pain to replace. It's only after they've been on for a couple of years and rusted and seized up that it's a pain to get them off without breaking them into pieces. I change mine twice a year, before and after winter. It takes me about 10-15 minutes a year to replace them, at the staggering cost of $15 per blade.

    So two nuns are on a road trip, when suddenly a tiny diminutive demon jumps on the hood, and plasters himself against the hood, making scary noises and faces. And the driving nun says, "Ah! What do I do?" So the passenger nun says, "Well, turn on the windshield wipers!" So the driving nun turns on the windshield wipers. But the demon just grabs on to the wipers, and now he's just going back and forth while making his scary noises and faces. And now he's agitated. So the driving nun says, "Ah! What do I do?" And the passenger nun says, "Well, turn on the windshield wiper fluid! It's filled with holy water." So the driving nun turns on the windshield wiper fluid, and it SEARS the demon, and there's all this screaming while there's a huge, thick cloud of steam. But when the smoke clears the demon is still there, going back and forth with the windshield wiper, with his flesh all seared, and now he's REALLY pissed, right? So the driver nun says, "Ah! What do I do?" The passenger nun thinks for a minute then says, "Well, show him your cross!" So the driving nun leans out the window and screams, "Get off my fuckin' hood!"

    At first glance this article makes absolutely no sense.

    A top layer that repels water. Swell. But how long does that layer last when subjected to your typical environment?

    A second layer of microscopic dust that somehow pushes dirt to the side. Can anybody fathom any mechanism for this?

    A third layer that's a sensor for dust? WTF?

    A fourth conductive layer?

    One possible mechanism might be that the fourth layer is charged up to several thousand volts, charging the unwanted dust, then it reverses polarity, repelling the dust. Which might have a chance of working at 0% humidity and very fine dust.

    Also note that the gratuitous reference to nanotechnology, which in this context probably refers to what we normally call "powdered ingredients".

          A brother-in-law talked me into applying an Amway window treatment, and I was amazed at how well it shed water. You could, and I did, drive alongside a semi at freeway speeds and the water just slipped off and out of sight. It was absolutely convincing. Its only drawback was that you had to reapply it every several weeks. At first it worked even down to 25 mph, but gradually wore off as you used wipers at slower speeds, especially if you used the washer fluid, and eventually you had to use wipers as high as, say, 50mph, at which point I would reapply it. That bottle ran out and I tried some others which worked as well.

          There was also a mental adjustment period for me; water just streams up and over the car, not to the sides, and it seems so wrong to not have wipers sweeping back and forth. The streams going up the windshield were so different from what I was used to that it was distracting and somewhat headache inducing, and it took several rainstorms to get used to it. But now it's wipers that look wrong.

          Until you see it from inside, it is hard to believe how well it sheds water splashed up by the semi alongside you, but it is literally almost as clear as having no water on the windshield. It made a believer out of me.

I say this as someone that doesn't like driving at night because of the glare of oncoming headlights, but I've never noticed any problem with glare using Rain-X. The thing is, you absolutely have to buff it thoroughly and well after you first apply it. Put some elbow grease into it!
    • I'm guessing it will cost more fuel. Instead of running one motor intermittently, you have to power an entire windshield, plus sensors, plus your rear view camera, plus the display unit, continuously. A silvered piece of glass doesn't use any fuel.

        No. It will cost 0. Yes, 0. Just like always-on lights we have in Canada cost, yes, 0.

        The gas engine wastes so much power anyway and never runs at optimal that the so called loses are meaningless. 100HP engine can generate 100W of power without any additional fuel costs. Heck, on a bike you generate 100W of power without too much effort. You can only speak of loses with some *efficient* hybrids or electric cars. But then the windshield doesn't need to be powered all the time anyway.

        Regardless, this technology may be most helpful in places where wipers are currently not used. For example, motorcycle helmets. Or cycling glasses.

          Yeah somebody up the page [slashdot.org] was talking about something called RainX. Making the outer layer hydrophobic seems to be the main trick here.

        • A 100 HP gasoline engine needs about 400W of fuel flow to make 100W of extra electrical power. That comes out to about 1 gallon per 90 hours of operation.

          While it might be essentially unmeasurable in your fuel bill, so is a single 100W bulb in your electric bill. It doesn't mean that it doesn't count.
        • You're really wrong. Back when they first came out, and gas was, iirc, 59 cents a canadian gallon (and not the $1.24 /liter it is today - $4.91 / US gallon or $5.64 / canadian gallon),it was calculated that running lights would cost an extra $25/year in fuel consumption.

          Today's running lights take less energy; however, we also drive about 50% more per annum than we did back then, so we still end up consuming at least . Of course, with the hgher price, you're now looking at annual costs easily over $100.0
