It looks just like transparent aluminum. They used it on Star Trek, so it must be real.

Aluminium oxynitride is a transparent ceramic composed of aluminium, oxygen and nitrogen. ALON is optically transparent in the near-ultraviolet, visible and midwave-infrared regions of the electromagnetic spectrum. Wikipedia
Formula: (AlN)x·(Al2O3)1-x, 0.30 ≤ x ≤ 0.37

Calling that transparent aluminium is a bit like calling (quartz) glass "transparent silicon" or lead glass "transparent lead".

 

[BillTre]

Does it conduct electricity?
Do bullets bounce off it?

Actually, from an astrophysics-astronomy perspective, anything heavier than helium is a metal. Oxygen, Nitrogen, Neon, ... all metals.

Do bullets bounce off it?

From the Wiki article:

ALON is the hardest polycrystalline transparent ceramic available commercially. Its combination of optical and mechanical properties makes this material a leading candidate for lightweight high-performance transparent armor applications such as bulletproof and blast-resistant windows and for many military infrared optoelectronics. ALON-based armor has been shown to stop multiple armor-piercing projectiles of up to .50 BMG cal.

What I want to know is whether you can transport whales with it.

Yes. That was the first use a few hundred years from now.

Why did they need transparent aluminum for the whales anyway? Do the whales get lonely if they can't see you?

 

[Ivan Seeking]

BTW. you can just take a flame to aluminum foil and make it transparent.

 

[jbriggs444]

Why did they need transparent aluminum for the whales anyway?

It is a unique material which was never discovered. Its existence stems from a closed time-like loop involving Scotty.

Glass IS transparent silicon dioxide. What is wrong with saying that?

 

[jbriggs444]

Silicon != Silicon Dioxide

 

[Ivan Seeking]

Silicon != Silicon Dioxide

Okay, transparent silicon.

 

[mfb]

It is transparent silicon dioxide, but it is not transparent silicon, because it's not silicon.

If you ask for an oxygen bottle and get a bottle of water, ...

Is there silicon in glass. Can you see through it. Or are you saying a silicon atom is no longer a silicon atom if it's bound to another atom?

We normally distinguish between wood, coal, diamond, water, oxygen and carbon-dioxide. We do not normally fill a CO2 fire extinguisher with "transparent carbon".

 

[collinsmark]

Here's a spoiler regarding the recent posts. The movie also involves whales, not shown in this video.

All right, fine. Here's a whale or two for good measure.

..., unless we're smuggling diamonds. (Presidio, great movie.)

CO2 is transparent, right?

I can play nitpicking games all day too. :)

 

[mfb]

CO2 is transparent, right?

Yes, but it's not carbon. See above. It contains carbon.

[Ivan Seeking]

So you can see through the oxygen but not the carbon. So you see little black dots?

I am pointing out the fallacy in his logic.

 

[ergospherical]

I am pointing out the fallacy in his logic.

what fallacy? the optical properties of compounds like carbon dioxide are determined by the vibrational modes of the molecule (e.g. CO₂ has a symmetric stretch, an antisymmetric stretch and a bending mode), and these have frequencies in the infrared (not visible) region so it is transparent. [Although, the symmetric stretch doesn’t change the dipole moment, so actually isn’t even IR active]

It’s not like some types of individual atoms are opaque and others are transparent…
