57" WS til mindre end 700$ om ikke engang tre år.
Eller deromkring. I artiklen taler der om " 50" wide TVs", så hvis det skulle være WS tv de taler om ville det være ca 57,4" i diagonalen. Som 4:3 ville det være 62.5". Men læs selv:

"Finally, a purpose for nanotech to turn on average Joe: Big-screen TVs

For a decade, scientists in prestigious labs worldwide have sweated over nanotechnology. They've worked at the outer edges of human knowledge, employing room-size, multimillion- dollar contraptions to try to create structures one-billionth of a meter across — the size of three or four atoms.

Motorola's Jim Jaskie, left, and Ken Dean work with carbon nanotubes in a scanning electron microscope.

And at last they have revealed a major outcome of this research — a product of magnificent importance to worldwide peace and happiness, not to mention the viewing of football games.

That would be: big-screen TVs.

Better: CHEAP big-screen TVs.

Just a few years ago, we were worried that runaway, self-replicating nanotech machines might cover the Earth like a locust plague and choke off all human life. So instead, nanotech is going to give us a reason to invite friends over to drink Coronas and watch Terminator movies.

Kind of a relief. Almost like finding out that french fries actually clean out your arteries.

The welcome news comes from Motorola. Last week, it announced NED, which stands for Nano Emissive Display. As explained by Motorola scientist Jim Jaskie, NED could be used to make 50-inch-wide, one-inch-deep, flat-screen TVs with the picture quality of high-definition television, but at the cost of 32-inch traditional cathode ray tube TVs.

Today, a 42-inch flat-screen TV would run you about $5,000. A 32-inch CRT model — maybe $700.

"Existing factories could be modified to make this," Jaskie says. Though Motorola won't make NED TVs, it will license the technology to consumer-electronics companies that will. "We're not talking about something that's three years out. It will be sooner than that," Jaskie says.

NED TVs are the most tangible result yet of research into carbon nanotubes, which are the early stars of nanotech.

Nanotechnology is about building structures smaller than anything ever made. One nanometer is one ten-thousandth the width of a human hair. Nanotech will allow researchers to devise materials and devices never before possible.

A nanotube is an artificially created lattice of graphite wrapped in a tube shape about 1.2 nanometers across. If you imagine Kraft macaroni and cheese for amoebas, that's the size and shape you've got here.

Turns out that these nanotubes are, like tiny cannons, excellent for firing electrons at something — say, for instance, phosphors on a screen, which when excited by electrons can create an image.

But to make a nanotube screen, you'd have to lay down a layer of neat rows of millions of nanotubes in position to fire patterns of electrons at the phosphors. Until now, a factory would have had to practically paste on the nanotubes one at a time, usually at temperatures hot enough to melt whatever materials were in the screen.

Motorola's breakthrough, Jaskie says, is a way to grow perfect fields of nanotubes right on a screen at low temperatures. It's like a bald man discovering Rogaine when he thought his only choice was a hair transplant — the former being a much less painful and difficult process. "If you can place a seed where you want the nanotubes, you can grow them," Jaskie says. "It becomes much easier."

Hard to believe? In fact, this concept of growing nanotech products — also called self- assembly — is getting some traction.

A few weeks ago, I stopped by IBM Research and talked with Chris Murray, a chemist leading IBM's efforts to similarly grow technology products. "We want to use what's in a flask to replace some of the complex manufacturing," Murray says as he stands in his lab next to a refrigerator marked by a big "No food!" sign. Wouldn't want somebody to come in looking for potato salad and accidentally eat a bucket of nanotubes.

In June, Murray and fellow scientists published a paper in the journal Nature describing how, for the first time, they got dissimilar materials to assemble themselves into repeating, 3-D nanoscale patterns.

It's a big step toward the day when a factory could pour together three or four materials, which would then turn themselves into, say, the surface of a computer hard drive. It's as if you could pour four colors of paint on a canvas and watch them make a portrait.

As nanotechnology and self-assembly become real, it should make all kinds of products less expensive, as shown by Motorola's NED TVs. It should also let companies build interesting new properties into mundane items. Tiny nanomachines might coat clothing so it can detect and warn you about viruses in the air. The military is testing such garb for bio-warfare, but it might someday be in regular clothes — handy, perhaps, on a first date.

Self-assembly is exactly what drove those old worries about nanotech. What if nanomachines started replicating themselves and couldn't be stopped? One theory is they could become an ecological disaster, quickly covering the Earth in a so-called gray goo.

But most nanotech scientists say that's unlikely. It's a theory that will probably prove to be much like worries among some Manhattan Project scientists, who thought that a single nuclear explosion could ignite the Earth's entire atmosphere and turn the planet into a ball of fire. Didn't happen.

Nanotech, it seems, has arrived. And before the end of the decade, it will probably be in many of our living rooms, serving up the NFL, movies and — hopefully to the delight of Buddy Ebsen's soul — an eternity of Beverly Hillbillies."


Oh mama! Projektor? Naaaaah :)

Det lyder godt nok spændende, men også lidt skræmmende. At skidtet kan bygge sig selv lyder jo helt umuligt...
A small cog? Now that you mention it, I know a puzzle about an object that almost fits that description.
