"Linear acetylenic carbon, also called carbyne, is an allotrope of carbon that has the chemical structure (−C≡C−)n as a repeating chain, with alternating single and triple bonds.[1][2] It would thus be the ultimate member of the polyyne family."

Hmm. Tensile strength of ~40X diamond. If my reading and numbers are correct that would yield a tensile strength of around 300 - 400 million PSI?

If they made that stuff into bolts and screws I bet I could still find someone who would find a way to over tighten them and round their heads out with nothing more than a Vice grips and or #2 Phillips screw driver.

Unusual units for strength in the Wiki article - N.m/kg. That's strength in Pa/density, kg/m3. A relevant parameter, as strength per unit mass is often important, but Wiki might have made it clear.

They'd over tighten it, snap it off, and now they wait for someone to develop a drill to drill through it for an easy out.

Yes the vice grips and phillips screw driver are notorious for rounding bolt heads, but you missed my pet peeve - the 12 point socket. Who ever decided that 6 weren't enough?

interesting, the 12 point socket was developed (like the box and open end wrench for tight spaces.

I see that Craftsman (so I assume that Snap-On and MAC also has this) ratchet wrench's that has a higher tooth ratchet for those tight spaces.

Don't care how tight the space is, if you have a very tight bolt, a 12 point socket is going to destroy the bolt head. Use a 6 point every where you can. Ever see a 12 point impact socket?

I see your point and understand it.

If you every worked in a blind tight space, that has a nut that is not frozen. you'd appreciate it.

For me, I have 6 point sockets as well as 12 point (12 point sockets are Snap-on Sockets, better tolerances) .

If its that upsetting to you, I shouldn't have to tell you this, but you really have to make life easier for yourself and stop buying the 12 point sockets and buy the 6 point.

But the 12-point socket can round off twice as fast as the 6-point socket, and almost as fast as the hex socket.

That's the point of all these socket/driver styles, right? To find a connector that ruins itself and the driving bit in the shortest amount of time? Perfection would be fasteners and bits that ruin each other before they even touch.

(And for those of you who don't read my signature, I'm being VERY sarcastic and snarky right now.)

Would a carbyne carbine make it through a metal detector?

It remains to be seen if they'll be able to manufacture a Crotch Lock from this material.

I understand that Billy Ray Cyrus is looking for such a device for his darling daughter Miley. ***SNARK....***

(Sorry, I just couldn't help myself this AM, due to a lack of strong coffee.)

"I understand that Billy Ray Cyrus is looking for such a device for his darling daughter Miley. ***SNARK....***"

He should have known better than to let her become a 'Disney Child Star,' the pressure to be 'Disney Clean,' aka "Practically Perfect in Every Way," can really lead to an oppressive childhood, especially if they're not pulled out of that environment before they hit puberty. Nothing Miley has done post-Hanna Montanna has surprised me. Shocking? Yes, in a way(1), but surprising? No, I expected her to push back, there's been a long precedent(2).

Notes:

  1. I've seen Madonna's career from the early 80's until today, she basically burned out my ability to be shocked with all her 'escapades.' Not even Lady GaGa is shocking to me; in my eyes, GaGa is "Madonna raiding Elton John's wardrobe department."
  2. And not just the child stars, the animators too. A bunch of Disney animators had their contracts come up for renewal at the same time in '79 or '80, and they all declined, heading off to make their own animated film, Heavy Metal, a 'cartoon' that was as 'anti-Disney' as could be without taking direct jabs at the mouse.

I quote from the web site..

"Carbyne, a carbon-based structure, has been a theoretical material since it was proposed back in 1885 with scientists only being able to produce it in either computer simulations or very short forms of only 100-atoms long due to its instability"

Typo? or windup?

No, after reading this, Fredski should be alright with it.

Let's see.......just what these scientists have done....

"Now thanks to a new production method involving rolling up two sheets of graphene", (quote from the article) they have produced Carbyne whose strength is "double that of current science darling graphene." (another quote from the article)

Hey, I'm impressed......!

And.... "have managed to synthesise a chain of 6,400 atoms long, which remained stable." (Remember, it is very strong!)

But...."and it can't even be seen by the naked eye".

I have 2,000 bottles of Carbyne, and I am selling them for the mere price of $2,000 U. S. dollars each. Just imagine what you can do with your bottle of pure Carbyne, one strand per bottle. I promise you, you can't see it, but it's in there. Any takers?
