Just in time too. I was not aware that we were reaching the limit of silicon chips. From CNN:

    Originally posted by CNN/Money
    Scientists at General Electric Co. unveiled one of the smallest functioning devices ever made Wednesday, a carbon tube about 10 atoms wide that could one day shrink computer chip technology.

    Researchers at GE's central lab in Niskayuna, N.Y., hope that their new device, which is a rolled-up sheet of carbon atoms resembling chicken wire, will someday operate as the standard semiconductor in computers and other electronics.

    The device -- a nanotube -- is part of a developing field of technology in which devices are designed on the scale of a "nano," or a billionth of a meter. That translates to about the size of 10 hydrogen atoms, or 1/80,000 the diameter of a human hair....

    .....GE's device has potential, according to Paul McEuen, a physics professor at Cornell University in Ithaca, N.Y. He said the company's work is a step forward for the science and shows that nanotubes have qualities that could allow them form smaller chips than those made of silicon, the most common material for computer chips.

I remember about 8 years ago or so, when the 500MHZ processors were about to come out. I read an article that said 500MHZ is about as fast as it will get because they had problems with electrons floating off the circuits or something...

I guess they were wrong...

I just spent twenty minutes writing a huge response (with links and everything). Then IE died, and I stabbed Bill Gates in the ribs. ARGH! Ah, so it goes. Anyway, take it from me: Carbon Nanotubes are way cool, but both UNC and Duke have been working with them for years... this GE thing seems like pretty old news to me.

I also had a big thing about silicon chips. Suffice it to say, we fixed the old problem (electrons shooting off whenever it hit a right angle in the circuit), but the new current problem (besides eventually running out of ways to shrink the circuits to fit more on a chip) is the fact that these have so much going on, they're hot enough to melt your motherboard. Intel's solution is to put in two processors and have each one do half the work, and Apple's was to invent a new cooling system.

No fancy links for you this time. Just google it.

California Nanosystems Institute has been doing some great work for a few years now.

thats a nanotube from 2001

I thought the big worry was that insurance companies were not going to cover Nanotech products due to potential asbestos-like danger from the small particles?
