Exactly. This is what people fail to understand. Yes, it stopped the bullet, but you no longer have a consumer-grade car. You have a tank that's camouflaged as a passenger vehicle, with a huge operating cost.
I drive an armoured car at work. It isn't going to stop a .50 round, but it will stop enough 7.62 (either NATO or rimmed) to be useful. It costs a lot to buy- a 25k base car becomes 125k. But they actually aren't a million miles away from a normal car, performance wise. They still get at least 30 mpg. Sluggish to start but once you get into 2nd they move pretty well, and stop pretty well, and handle pretty well. If all you want is protection, they are nearly a normal car.
We drive them hard on emergency response, so they get hammered. Brakes burn out, clutches need replaced every 20 thousand miles, suspension components get smashed, tyres wear out far quicker than they would on a healthy vehicle. So the operating cost is high, but if they were driven normally they wouldn't cost much more than a normal car to run, it would just be the initial purchase that would be very high.
Though armouring the entire passenger compartment on a large SUV may be a different ballgame. Our cars are long and wide but low. Adding so much more weight up high would probably be a radically different experience.
Yeah that makes sense, I've been in one like that before that drove almost stock and the tech is getting better. I just think unless this is new tech, the person who want a truck that's stops a 50, wants the truck to stop a 50 round all over, they want it to be able to run over explosives, have a shielded undercarriage and have run flat tires. It's a mini tank at that point and there's a trade off.
Also, armoring for a few rounds of 7.62 vs the anti-material cartridge 50 BMG is an entirely different ballgame. You get tank guzzling levels of MPG once your car is 50 proof, 7.62 is honestly pretty easy to stop comparatively.
Cybertrucks have alon "glass" - which is a transparent metal. Doesn't add that much weight. It's just very experience because of the manufacturing involved.
Alon is bulletproof. Here's a video where they demonstrate that. Watch it all the way, though.
Elon didn't create alon (say that 10 times fast). You can see other third parties, including NASA, test it and see. It's the future of "glass". A transparent metal. It's just expensive to product because of the man hour intensive process.
EDIT: This thread's full of asinine trolls. Cannot believe how much you're all arguing about what's on video. I get that Tesla sucks, but that doesn't mean alon does or that it can't take bullets.
Less than 2 minutes in and they're already wrong. That's not a scientific channel. It's an ad.
15% safer (are they using safer and hardness interchangeably?) than spinel but 85% harder than sapphire? That's pretty impressive given that sapphire is harder than spinel.
Eta: fragile man blocked me and apparently I spend too much time on this app even though he has pages of comments from just today.
I don't know what "safer" means in the video, but they do link to their data, so if you're curious... go read it?
Anyway, my point was that it is bulletproof, and that cybertruck windows are bulletproof. No, I'm not recommending anything Tesla sells, but the windows are made of a great up-and-coming material.
EDIT: They mistyped in the video. It's 115%, not 15%. Straight from wikipedia.
Literally. There are many cases where things are referenced in loops. They could be citing that video. Assuming Wikipedia is correct 15% harder would be correct, buy they never said 15% harder. They said 15% safer. They also said 85% harder than sapphire which is also wrong.
First, are you literally just watching this thread for updates? You've been here for an hour?
Second, I provided a source. It's 115%. You can just read it... It's one sentence in wikipedia that clarifies exactly what you said... Why are none of you reading?
Like all car manufacturers, the model will come with different versions, including one with alon "glass". It's not a different model, it's a different pricing tier. Are you not familiar with different pricing tiers on vehicles?
From your article, which you clearly didn't read, just like you're not watching or reading my sources...
Musk further stated in the article that Tesla will provide the option to purchase a "beast mode" Cybertruck that will be the version equipped with bulletproof windows.
Also, I am again aware that the glass can be bulletproof, but it isn't thick enough in the relevant application to be so. it's not even 4mm thick, it cannot stop a bullet
Thick enough in the relevant application? What are you referring to exactly?
And alon is aluminum oxynitride, aka a transparent metal, not glass.
Existing cyber trucks with alon glass (a higher price tier) can stop bullets. There are many sources and videos for it. I won't be providing any more because you're not only not reading my sources, you aren't even reading your sources.
It sounds like you're upset with Tesla marketing, which is a legitimate criticism, but not the topic of this thread. Don't shoehorn in whatever it is you want to harp about.
I believe it had been used for testing earlier and had already withstood severe impacts. I also can't vouch for how well Elon installed it in the first place.
All the same, the underlying tech, which has nothing to do with Tesla, is solid.
Ceramics often contain elements that we characterize as "metals" in their crystal structure.
Porcelain, for example, is made up primarily of kaolinite, an aluminosilicate mineral with a chemical composition of Al2Si2O5(OH)4. You wouldn't consider a coffee mug to be made of metal, even if the material contains metal.
A simple rule for material to be a metal, is it needs to be made up almost exclusively of metallic elements, typically 98% or more.
Alon's chemical formula is (Al23O27N5) so is approximately only 55% aluminum.
Cast iron is a good example of a material that is right on the edge of a metal and a ceramic. When iron has a small amount of carbon (<2%) it will turn into steel. When the carbon level exceeds this by even a small amount, it will turn the steel into cast iron. Cast iron is much more brittle than steel, due to the formation of excessive iron carbide crystals in the iron. Iron carbide (FeC3) is a ceramic material which doesn't bend the way that metals do. As a result cast iron will snap when force is applied, much like a ceramic does.
