"You're right about optical fiber, Mydesign. Copper is being replaced by optical fiber for high-def video, even in such places as surgical suites."

Charles, thanks for the link. Would you think that in future these optical fibre can replaced by some other transfer mechanisms like laser or Ultra sonic waves etc.

"the idea is definitely revolutionary, although it isn't new, as we see from 10 years of research. But copper doesn't complete disappear from the board--not yet, anyway."

Ann, copper cannot be replacing immediately, but i think one day it has to happen.

78RPM, this is Dow Corning, not Corning, in case you were confusing the two. It's easy to do.

Pubudu, thanks for the comments. Could you clarify your question? Optical fiber is already being used for general-purpose data transfer at longer distances.

William, I agree. Even after 10 years of problem-solving, I bet there will be lots left for engineers to do on the board for some time to come.

Ann Very interesting article, there will be no doubt in future when it comes to the data transfer

But will this be ok for the long distant data transfer and cost-effective for the general purpose data transfer?

It will be very interesting to see the completely new set of problems that will come up if this idea ever is used. New problems to make sure we engineers never run out of problems to solve.

I remember hearing about a computer that was built completely with fiber optics back in the late 90's. I think it was designed by the R&D department of one of the major tech universities. We were "photofied" as well!

Nancy, I first heard of switching photons instead of electrons about 15 years ago in a venture capitalist meeting about a new tech, I forget which one or from which company. I was electrified--or perhaps I should say, photofied.

Lots of people who write about robots say they give us jobs, instead of taking them away from humans. Based on the evidence in some recent studies, I'm not so sure.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
Purdue researchers have used a commercial sewing machine to quickly create stretchable electronics from conventional thin wire and a silicone elastomer used for making special-effect movie masks.
Researchers at MIT's d'Arbeloff Laboratory are developing shoulder- and hip-mounted robotic arms to help workers in aircraft manufacturing perform difficult or complex assembly tasks that would normally require two people.
