WASHINGTON – Top scientists in Israel are on the verge of a revolutionary breakthrough, creating a cloak that can render a person invisible.
In their real-world quest for invisibility, scientists at Ben-Gurion University have developed a device that scatters light away from an object so it cannot be detected, making the object invisible to the eye.
Physicists developed the method for concealing objects based on the study of “metamaterials,” which focuses on exploiting and controlling light by examining how it interacts with objects.
Those arrays of minuscule components bend, scatter, transmit or otherwise shape electromagnetic radiation in ways that no natural material can, according to Nature.com.
Bending electromagnetic radiation, such as light, around an object, gives the appearance that the object isn’t there at all, but still can be located by infrared sensors or radar.

Interesting for sure. Glad you liked it.
A life without broken things! Now that would be the ultimate Christmas present.
It will make spying.....and turkey hunting a lot easier.
It just occurred to me some of the non-military/covert stuff that this could be used for. Want to make the neighborhood look better - coat thestreet side of the utility boxes and/or the dumpsters in it.
Want to make a utility room feel more expansive - coat the front of your water heater/furnace in it.
A hole new tool box for home designers and city planners.
Thermal and thermal plus light amplification goggles both still pick up what's not visible to the naked eye, at least that's what I read about this or something very much like it a few years ago.
Hogwarts has had it for centuries.
“Think how much groping Al Franken could do wearing one of those babies.”
As a kid I was fascinated by “The Shadow” radio show. Oh what a gift to become invisible on demand! My devilish side has all kinds of ideas!
“Possible solution to the “Man in the Woman’s room problem”?”
Fir those weird enough to want to watch.
Younger kid’s black lab turns 2 years old in about a week and he’s super hard to get a good photo of, especially indoors. On a side note, we refer to him as the BDITHOD*.

No. They actually have no spines.
“Not long ago, the biggest civilian market for an invisibility cloak would have been boys wanting to hang out in the girls locker room. That market has probably dried up now; because boys just have to declare that they’re actually girls, and waltz right in.”
Can you declare it for the moment then afterwards declare back to being a male?
Just another quintessential Lab.... ;-)
Decent series too.
The often rumored Philadelphia Experiment where they made a ship disappear is becoming reality.
Per Wiki:
The Philadelphia Experiment is an alleged military experiment supposed to have been carried out by the U.S. Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, sometime around October 28, 1943. The U.S. Navy destroyer escort USS Eldridge (DE-173) was claimed to have been rendered invisible (or “cloaked”) to enemy devices.
The story first appeared in 1955, in letters of unknown origin sent to a writer and astronomer, Morris K. Jessup. It is widely understood to be a hoax;[1][2][3] the U.S. Navy maintains that no such experiment was ever conducted, that the alleged details of the story contradict well-established facts about USS Eldridge, and that the claims do not conform to known physical laws.[4]
The experiment was allegedly based on an aspect of some unified field theory, a term coined by Albert Einstein to describe a class of potential theories; such theories would aim to describe — mathematically and physically — the interrelated nature of the forces that comprise electromagnetic radiation and gravity, in other words, uniting the fields of electromagnetism and gravity into a single field.
According to some accounts, unspecified “researchers” thought that some version of this field would enable using large electrical generators to bend light around an object via refraction, so that the object became completely invisible. The Navy regarded this of military value and it sponsored the experiment.
Another unattributed version of the story proposes that researchers were preparing magnetic and gravitational measurements of the seafloor to detect anomalies, supposedly based on Einstein’s attempts to understand gravity. In this version, there were also related secret experiments in Nazi Germany to find anti-gravity, allegedly led by SS-Obergruppenführer Hans Kammler.
Diffused lighting camouflage was a form of active camouflage using counter-illumination to enable a ship to match its background, the night sky, prototyped by the Royal Canadian Navy on corvettes during World War II. The principle was discovered by a Canadian professor, Edmund Godfrey Burr, in 1940. It attracted interest because it could help to hide ships from submarines in the ongoing Battle of the Atlantic, and the research project began early in 1941. The Royal Navy and the US Navy carried out further equipment development and trials between 1941 and 1943.
The concept behind diffused lighting camouflage was to project light on to the sides of a ship so as to make its brightness match its background. For this purpose, projectors were mounted on temporary supports attached to the hull. The prototype was developed to include automatic control of brightness using a photocell. The prototyped concept was never put into production, though the Canadian prototypes did briefly see active service. The Canadian ideas were, however, adapted by the US Air Force in its Yehudi lights project.
That was on before I ever got Direct TV. I lived in the country on 12 acres and they told me they couldn’t get a bead on the satellite because of the trees. Sorry I missed that. Perhaps they have it on DVD.

One of the Predator movies I take it. 8>) Never actually watched the entire movie, but have seen a few scenes.
