Transparent aluminum

Also known as aluminium (to normal people).

From Star Trek IV - the crew have gone back in time to 1986. Scotty and Bones are visiting an engineering plant and need to bargain with the director to get his help...
113 INT. NICHOL'S CUBICLE - DAY 113

An impressive glass-walled cubicle separating the boss
from the factory chaos. Nichols leads Scotty and Bones
inside.

NICHOLS
Well, so much for the tour of our
humble plant. I must say,
Professor your knowledge of
engineering is most impressive.

BONES
Back home, we call him the miracle
worker.

NICHOLS
Indeed... May I offer you gentlemen
anything?

A look between Bones and Scotty. Then:

SCOTTY
Doctor Nichols, I might have
something to offer you.

NICHOLS
... Yes?

SCOTTY
I notice you're still working with
polymers.

NICHOLS
(mystified)
Sill? What else would I be working
with?

SCOTTY
Ah, what else indeed? Let me put it
another way: how thick would a piece
of your plexiglass need to be at 60
feet by 10 feet to withstand the
pressure of 18,000 cubic feet of
water?

NICHOLS
That's easy: 6 inches. We carry
stuff that big in stock.

SCOTTY
Yes, I noticed. Now suppose -- just
suppose -- I could show you a way to
manufacture a wall that would do the
same job but was only an inch thick.
would that be worth something to
you, eh?

NICHOLS
... Are you joking?

BONES
He never jokes... Perhaps the
professor could use your computer.

NICHOLS
Please...

He gestures, and Scotty sits at a nearby Macintosh. He
surveys the machine quizzically, clears his throat, and
in a loud voice says:

SCOTTY
Computer --

Bones steps in quickly, picks up the "Mouse" and shoves
it into Scotty's hand. Scotty looks at the mouse,
baffled, then puts it to his lips like a mike.

SCOTTY
(continuing)
Hello? Computer...?

NICHOLS
(bewildered)
Just use the keyboard...

SCOTTY
The keyboard... How quaint.

Then, preparing his fingers like a concert pianist, he
plunges to work furiously.

114 CLOSE - COMPUTER SCREEN 114

An awesome series of figures and graphics are
appearing. PULL BACK to reveal Scotty, now master of
the keyboard, while Nichols watches in awe, next to
Bones. with a flourish, Scotty hits a last command,
and a wondrous three dimensional graphic appears.

NICHOLS
(wide-eyed)
Transparent aluminum?

SCOTTY
That's the ticket, laddie.

NICHOLS
... But it would take years just to
figure out the dynamics of this
matrix...!

BONES
You'll be rich beyond the dreams of
avarice.

SCOTTY
So, is it worth something? Or
should I just punch "clear"...

NICHOLS
No!
Okay, everyone.

It's been twenty years since Scotty revealed the secret - who can figure out the dynamics of the matrix? I demand transparent aluminum!

I've got a whole load of it in the shed. It was left here by the previous owners. Most of it is scratched though, as we've been leaning the lawnmower on it.

I guess.... You could... Eh...

Umm... Strengthen the aluminium with a Taclit field, and then align every single atom at precise angles allowing light to penetrate it.

But wouldn't it be easier to makes some new material like nanotubes or something?

No.

Transparent aluminum or nothing. :hmph:

Poke a few holes in some tinfoil (aluminuminum foil) voila!
At least I'm housebroken.

Perhaps not, but we are starting to get a handle on meta-materials with a negative refraction index.
According to Micho Kaku, if you would weave with carbon nano tubes, the result, if only a few atoms thick, would be near transparent to visible light.

This is more like it...

I don't think Dev should get his transparent aluminium until he confesses to what nefarious use he intends to put it.....

Don't, whatever you do, leave out the reverse polarity stage. Could be fatal. :coffee:

My watch has a sapphire glass. Sapphire is aluminium oxide and the manufactured ones for the high end watches are clearer than ordinary glass, and only diamond can scratch them, so it has been achieved, in a way.

At this point on the other forum the question would be deemed answered and this thread would be locked. :lol:

would transparent aluminium based ceramic satisfy your requirement?
Transparent aluminium foil can be made, but since this is achieved only by hard X ray bombardment of the sheet, the electron structure takes no time in returning to a more normal configuration, which restores opacity.

Also, sapphire glass is a form of alumina, aluminum oxide... so if the synthetic sapphire fits the bill, I guess the easier to make ceramic does too.
