rarbatrol posted:On a similar note, Koenigsegg uses a "ghost light" effect to light their dash buttons on the Agera. I've read it's aluminum with nanotubes going through it, so it looks like a solid piece of metal when the backlight is off. I'm having a hell of a time finding a good picture of it, though. Just laser drilling like Apple's notebook LEDs right?

Basically tons of little holes, that when light comes on from behind make it 'transparent'. The FaceTime/iSight camera green led is like this, as well as the 'breathing' indicator on the front.

I can't be the only one who built these when he was younger, right? I also had a Wankel and some sort of WWII fighter plane that had an electric motor in it that would spin the propeller and raise and lower the landing gear.

Known as the "Carbon fiber PV", since what they did was take a PV444, strip the unibody bare, measure it, and then remake it completely from CRP. https://www.youtube.com/watch?v=1zyDgepdRDY

It has the rather cool property that it is one-way bulletproof. It'll stop a light anti-tank weapon from the outside, but from the inside you can shoot through it with a standard pistol and it won't even deflect the bullet flight, meaning those SS guys are going to shoot back and they are going to hit, while you can't target them. A big homogenous block of something won't have that party trick

Sapphire is aluminium oxide and can be completely clear with the right composition. It is in fact used in armored windows, watches and so on. Gorilla Glass is similar in that it also contains aluminum, but it's more of a mix of ordinary glass and sapphire.

Gorilla glass is glass submersed in molten potassium salts. The lighter sodium ions exchange out for heavier/bigger potassium ions. When the glass cools and contracts, this "presses" the surface together, making it tough. Think of it like stretching a nylon net open and then placing it on a bed of grass, then contracting it. The grass gets "stuck" in the holes, making the net (comparatively) tougher. This compression in (usually just) the surface of the glass compared to the comparative lack of compression more atoms deeper is also why gorilla glass (or any toughened glass, really) fails so spectacularly when it eventually does. It's under constant compressive tension. Sapphire is still better, though. It is about eight times harder than normal borosilicate glass, and four times harder than quartz glass. Before I threw my life away and joined the NG I was an optician, and glass and plastics continue to be a hobby. Queen_Combat fucked around with this message at 12:34 on Mar 26, 2013 |

So it's basically like prestressed concrete, a material that's notably lovely strength wise in anything except compression, engineered to always be under compression unless the stress gets high enough to overcome the preloading/prestressing? Neat, I always wondered how they made tough glass.

Unless there's a backstory to this involving a sanctimonious Prius owner going out of their way to lecture the diesel driver on how they're polluting the environment and making Mother Nature cry, this isn't awesome. It's just a dick move from some bro who thinks driving around town with his new smoke chip dumping smoke on all the "gay cars" is cool.

Transparent aluminum exists in two forms right now. http://blog.makezine.com/2012/01/17/transparent-aluminum/ This is a form made from aluminum ceramic powder that is completely clear, can be made into sheets or any form, and can stop bullets. This one was just invented last year, and is made of actual aluminum foil, though it's impractical and expansive for any practical use yet. http://gajitz.com/science-you-so-crazy-transparent-aluminum-made-in-lab/

Still, the video definitely gives the impression that there's a limit to the number of hits those windows will take, and I don't think they'd risk the president like that - better to keep him safe, and allow backup to reach him. What's the furthest away from intense military power the US president will ever be, right? Krakkles fucked around with this message at 20:29 on Mar 26, 2013 |
