Invisibility cloak one step closer, scientists say

Scientists have created two new types of materials that can bend light the wrong way, creating the first step toward an invisibility cloaking device.
One approach uses a type of fishnet of metal layers to reverse the direction of light, while another uses tiny silver wires, both at the nanoscale level.
Both are so-called metamaterials — artificially engineered structures that have properties not seen in nature, such as negative refractive index.

The two teams were working separately under the direction of Xiang Zhang of the Nanoscale Science and Engineering Center at the University of California, Berkeley with U.S. government funding. One team reported its findings in the journal Science and the other in the journal Nature.
Each new material works to reverse light in limited wavelengths, so no one will be using them to hide buildings from satellites, said Jason Valentine, who worked on one of the projects.
“We are not actually cloaking anything,” Valentine said in a telephone interview. “I don’t think we have to worry about invisible people walking around any time soon. To be honest, we are just at the beginning of doing anything like that.”

WELL I DID’NT SEE THAT ONE COMING;
ON A MORE SERIOUS NOTE THERE ARE A NUBER OF WAYS THEY ARE WORKING ON TO ACHIVE THE CLOCK EFECT NONE THAT I KNOW OF ARE COMPLETE. BUT THEN IF THEY WERE HOW WOULD WE KNOW?
Hmm!
TRICKY!

anyone whos seen any youtube video on black (military) technology has seen this. this is neither new or news. lame!!!

Why should we trust anything they have to say, how do we know what thye really have. They probaly already have this anyway. So that’s all we need, great.

theyve also also got nano technology

they also have nanotechnology go to these sites
http://www.zyvex.com/nano/
http://www.nanotechnology.com/
http://en.wikipedia.org/wiki/Nanotechnology
these are just 3 theres more do a search on nanotechnology
also does anyone play or have ever played Anarchy Online?
guess what those who have played it know that the game is based on
nanotechnology

This will help McNobb achieve raping qoutas. Better watch out, espeically straight men, gonna have your blackcherrys

This technology has been around since the late 1980’s.

Let’s see this is going public today that means they have perfected it about 40 years ago….. We need to replace our government with ONE THAT WILL SHARE WITH US!

Now! Comming soon Martial Law Invisible soldiers! YYEEAAHH!!!!!
August 11th, 2008 at 10:35 pm
Invisible Martial Law Soldiers with duct tape and tasers!!!!!!!

Old new’s this has been around for decades!
The only reason your hearing more about it is the fact that it’s going to be made available for commercial use ie. hunting, PI’S. ect.
Just like all the chip’s which are being used today in video game consoles.

At least the duct tape and the tasers will be hard to concel ))

The invisibility cloak was allegedly first developed during the Montauk Project years. There is optic invisibility technology installed in the B2 bomber, apparently.

What Difference does it make Our Government thinks and act as if they are invisible anyway!
August 13th, 2008 at 5:15 pm
I’ll take one! ( And which way is the girls dorm?)
August 13th, 2008 at 5:20 pm
How could this have been around for years if they are using nanoscale structures?
I don’t doubt there are other ways of doing it, but it sounds a little far fetched.
