Okay, solid state then ;) Point is, besides this technology, conductors are exclusively crystalline conductors in solid state electronic devices.

Respectfully disagree. Many conductors are crystalline, others are not. Crystallinity may change the conductance of a material, it is not the overriding factor controlling conductivity. It is really a complex topic.

Conduction is at heart a matter of having electrons free to move about in a material. We can simplify our view of a metal by thinking of it as a gas of electrons moving freely in a metal responding to applied electric fields. This is why most metals look more or less the same (shiny metallic appearance). Light reflects off the freely moving electrons producing a shiny surface.

Even if a metal is crystalline when formed it may lose all or part of that crystallinity due to mechanical deformation. Rolling, stretching or otherwise deforming a metal may cause the crystal grains to change shape or become aligned or may cause them to be destroyed all together. Soft metals like gold, lead, tin are notorious for this.

You can use an EBSD device in an electron microscope to view and map these crystal grains. One of the biggest problems in this field is preparing a sample with a clean surface without damaging or destroying the crystal structure. Ion polishers use a low angle spray of argon ions to blast away the surface atoms without doing much damage to the underlying structure.

Apple hooking up with Liquidmetal seems like a perfect match. LM makes a very high tech engineered metal for special needs and Apple designs products with a passionate attention to detail that could use these materials better than most other CE companies. Can't wait to see what results.
 
Term "moronic" in general should be reserved for Apple fanboys who do not know much about anything but Apple. Apple indeed released its first laptop in 1991 (PowerBook 100). But other companies had being already selling them for years. From Wikipedia: "The first laptops using the flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981-82, but was not marketed internationally until 1984-85. The $8150 GRiD Compass 1100, released in 1982, was used at NASA and by the military among others. The Gavilan SC, released in 1983, was the first notebook marketed using the term "laptop."[8] From 1983 onward, several new input techniques were developed and included in laptops, including the touchpad (Gavilan SC, 1983), the pointing stick (IBM ThinkPad 700, 1992) and handwriting recognition (Linus Write-Top,[9] 1987). Some CPUs were designed specifically for low-power use such as laptops (Intel i386SL, 1990) and were supported by dynamic power management features (Intel SpeedStep and AMD PowerNow!) in some designs."

Oh no, don't just quote wikipedia. Please list all the laptops in history with cases made of superior alloys (for a laptop computer) to the current Apple MBPs.

So far you're at....zero.
 
Has anybody yet posted what the amorphous portion even is?

I make multi-modal castings of various materials and particle sizes and amorphous properties and viscosities and flow properties.

The missing link seems to be what filler they use and in what proportion.

It could be as simple as carbon of a particular shape and property that improves the mechanical properties, at a flow cost, within reasonable margin.

It's probably all version 1.0 or 1.2.

Transparent Aluminum on the way :D

Unlikely...

"To create transparent aluminium, more power than is used by an entire city had to be focused into a dot with a diameter of less than one-twentieth the thickness of a human hair, and then could only maintain the transparent state for 40 femtoseconds" -- wikipedia
 
Mimetic Polyalloy

Steve: So this new iPhone? It's an iPhone 4 like yours, right?
Terminator: Not like mine. An iPhone-1000. Advanced prototype.
Steve: You mean more advanced than iPhone 4?
Terminator: Yes. A mimetic polyalloy.
Steve: What the hell does that mean?
Terminator: Liquid metal.

So, Apple finally admits that using aluminum was a stupid idea. Other companies were using alloys for laptop cases for decades, now Apple decided to join them. Better late than never, I guess.
Um, no, I didn't see any such admission. I just saw that they found something better.

And my Macbook Pro is one of the best laptops I've ever had. It's certainly remained far cooler to the touch than any other. You're worried about dents? With plastic I got heat. So much heat I could hardly type. And other people I knew had one drop and their plastic computer cracked and was dead. I'd rather have a dent and the computer keep going.

Seems to me the only reason you find aluminum "stupid" is because of a cosmetic reason. "Oh woe! There's a dent!" You want your computer forever pretty. I'd like that, too, but I'll put having it cool and still working after a fall before that. As aluminum has done both of those brilliantly (at least for me), I'd say you're completely wrong about it being "stupid."

While I respect your knowledge on the subject, you still have not actually provided an instance where a classical crystalline like structure is not best for conducting paths in electronics. Moreover, I think you're falsely downplaying the role that the well-structured lattice has on conductance. After all, it is the unique lattice properties of superconductors at very cool temperatures that make them superconductors.
 
I can't wait for Steve to stand on stage and reveal the iWeapon X. It will be the perfect killing machine but who knows if it will have multitasking on launch. But it will definitely be used to kill adobe flash.
 
In fact the computer considered to be the first laptop had magnesium alloy case: "Designed in 1979 by a Briton, William Moggridge, for Grid Systems Corporation, the Grid Compass was one fifth the weight of any model equivalent in performance and was used by NASA on the space shuttle program in the early 1980's. A 340K byte bubble memory lap-top computer with die-cast magnesium case and folding electroluminescent graphics display screen."

Here is another Grid Compass computer (probably descendant): GRiD Compass 1101. Quote from this page: "Designed to be the ultimate portable computer, the clamshell-style GRiD Compass 1101 is the grand-daddy of all present-day laptop computers.

The Compass is very high-tech, with its flat-black, die-cast magnesium-alloy case, and bright, sharp electroluminescent display (ELD). No other system packed so much speed and power in as small a case, and none had such a unique and large, easy-to-read screen, allowing full 80x24 text. "
What a failure of a post. This is hardly the "Other companies were using alloys for laptop cases for decades, now Apple decided to join them" you previously mentioned. Grow up.
 
Impressive. You cite a government top secret laptop for NASA and compare it to consumer product laptop. Genius is not thy name.

Nope, his name is Troll.

Haters never grow up, they just register under new names and keep on trollin'.
 
this just in... your laptop can morph into a cyborg that will travel through time and try to kill Linda Hamilton.

Zr41.2 Ti13.8 Cu12.5 Ni10 Be22 - Their most common alloy
 
Does this mean hotter MacBooks?

The company website also list "thermal conductivity" as a strength, which I assume the alloy would be better at conducting heat.

I hope this doesn't lead to even hotter MacBook Pros, they are hot enough as it is.

There is a good article about Liquidmetal in wikipedia.

The Liquidmetal itself is amorphous in that it doesn't form the well ordered crystals that are characteristic of metals. Liquidmetal seems to have a random arrangement of molecules similar to what is found in glass.
 
This amorphous atomic structure leads to a unique set of characteristic properties for the family of Liquidmetal alloys.

These characteristic properties are:

- High Yield Strength
- High Hardness
- Superior Strength/Weight Ratio
- Superior Elastic Limit
- High Corrosion Resistance
- High Wear-Resistance
- Unique Acoustical Properties

....

I am not amused.
 
Rearden Metal?

Not a single reference to Rearden Metal? I know we're all geeks here, but sci-fi can't be our only passtime. Any objectivist geeks here?
