        ALONtm is virtually scratch resistant, offers substantial impact resistance, and provides better durability and protection against armor piercing threats, at roughly half the weight and half the thickness of traditional glass transparent armor, said the lieutenant.

        [time warp]

        Tuesday, October 13, 2009

        Cupertino CA -- Apple Computer faces rising complaints of "scratches" that reportedly developed on the cases of their iPod Angstrom virtual reality player. The device, which feeds audio, video, and olfactory images directly to the brain, is implanted under the skin behind the ear, remaining there for up to three days. It is this repeated insertion and extraction of the device which causes scratches on the iPod's case.

        "The scratches are obvious," say disgruntled user Mitch Burnsome, "I can see them clearly under my microscope, at maginications as low as 20 times. Apple's quality control is dreadful."

        Apple responded that the iPod Angstrom case is very durable. "The case is made of ALONtm which is used as armor on tanks and Humvees; it's virtually scratch resistant," said Apple spokesperson Anton Natale. "Steve Jobs has been using a prototype for the past six months and declares that it works so well with his brain that it's 'sanely great'."

        Since the release of the iPod Angstrom four hours ago, Apple has sold 7 million units. The price of Apple stock dropped 7% after analysts complained that sales were projected to be 7.1 million units by this time.

      • In other news, a man ,Homeland Security believes to be a Chechen rebel, was seen wandering the streets of nearby towns looking for nuclear wessels.Is it a coincidence he has shown up just as transparent aluminum has become a reality? He was accompanied by a dark skinned woman of possible Somalian origin. They are just people of interest at this point.

    In a June 2004demonstration, an ALONtm test pieces held up to both a .30 caliber Russian M-44 sniper rifle and a .50 caliber Browning Sniper Rifle with armor piercing bullets. While the bullets pierced the glass samples, the armor withstood the impact with no penetration.
    OK, I'm not exactly a gun nut, but that's damn impressive. .50 cal snipers are designed to take out the engine blocks of vehicles. A window stopping them is just plain cool.

    The uses go way beyond windshields. How about full-length transparent SWAT shields? If it'll take a .50-cal, should be more than safe enough. How about implrementing some of this in monitor screens? Watch faces? Heck, light fixtures in gymnasiums.

    What about airplanes? Make much of the body out of this, making maintenance that much easier.

    ... in retrospect, that last is a horrible idea. But the others remain good ;)

    Unfortunately, from the article it seems ALONtm is noted for it's high compressive strength, whereas to build the sides of a whale-sized bath you need high tensile strength. Unless of course it's a particularly aggressive whale and keeps shooting armour-piercing rounds at the side of the bath, but then the bigger question would be "how did it pull the trigger"?

    Never trust a journalist to get gun facts straight.

    The M44 is a carbine version of the Mosin-Nagant [wikipedia.org], very short, easy to carry, but with nothing better than iron sights. It is about as far from a "sniper rifle" as anything you can see.

    It has the coolest integral bayonet, though.

    On the upside, the M-44 uses the same cartridge as the current Romanian "sniper" rifle, the PSL [wikipedia.org]. The M44 has a short barrel so a steel-cored 7.62x54R [wikipedia.org] projectile won't reach the same sort of velocities as it would out of a PSL rifle but it should be a pretty effective test against the sort of "armor piercing" light arms that any terrorist not carrying an RPG [wikipedia.org] would be likely to have handy.

    This stuff is transparent Aluminium, in the same way that "normal" glass is
    transparent Silicon. Indeed, using this criteria, we already had transparent
    Aluminium in the form of Saphire. Saphire is also rather hard and makes a good
    optical material. While the invention of a suitably hard and tough transparent
    material is obviously news-worthy it would be wise to steer clear of the same
    mistakes that sci-fi writers make when they don't understand the "sci" bit.

    However, going back to the Star Trek film in question, I always liked the way
    that Scotty was able to create a new material and presumably the method for making
    it on a tiny Apple Mac Plus! Was he using MacDraw I wonder?

For those of us who look through tank windshield all day (figuratively speaking), if this material can be reduced in price and has a refractive index significantly greater than 1.66, then it would make our lenses much thinner, as well as being much more scratch resistant than polycarbonate.

    Given that sapphire has a refractive index over 1.75, this *could* be a great breakthrough - if Big Green starts to consume large quantities of this, then the amortized NRE will be greatly reduced.
