In the past researchers have only been able to "cloak" microscopic objects using extremely complicated physics and so-called meta-materials made on a tiny scale.

But a new study at the University of Birmingham has taken a massive step forward by making a paper clip invisible – an object thousands of times bigger than previous experiments.

The research works by using a naturally forming crystal called calcite which has extraordinary light bending abilities.

By placing the crystals over an object it "bounces" light around it rendering it totally invisible to the naked eye.

Dr Shuang Zhang, a physicist and lead investigator from the University of Birmingham, said: ‘‘This is a huge step forward as, for the first time, the cloaking area is rendered at a size that is big enough for the observer to ‘see’ the invisible object with the naked eye.




"By using natural crystals for the first time, rather than artificial meta-materials, we have been able to scale up the size of the cloak and can hide larger objects, thousands of times bigger than the wavelength of the light."

The new technique is only limited by the size of the naturally formed crystals.

Calcite crystals can be up to 21ft long so it could be used on a car or a military vehicle.

It may also be possible to manufacture crystals with similar qualities.

Dr Zhang said: "Previous cloaks have succeeded at the micron level – much smaller than the thickness of a human hair – using a nano- or micro-fabricated artificial composite material.

"It is a very slow process to make these structures and they also restrict the size of the cloaking area.

"We believe that by using calcite, we can start to develop a cloak of significant size that will open avenues for future applications of cloaking devices."

The research is published in the journal Nature Communications

That crystal doesn't look invisible to me...

I saw an article about this today. It included a demo video. Now I'm not sure if this is exaclty the same technique as they have been talking about but it looks pretty good. I think it would be a freak out to be sitting there and all of a sudden a Terminator or Predator uncloaks right next to you. I wonder how noticable it would be with the shimmering. In the desert it wouldn't matter. On the ocean it would be the same. It looks very effective to me..hmmmm.

It would give off a heat signal though wouldn't it?


Eat your heart out, Harry Potter. Scientists in the United States have created an "invisibility cloak".
"The 'cloaking device' exploits a 'light-bending' phenomena most of us will be familiar with - the mirage - but created by a heated filament of carbon," The Daily Mail has reported.

"The effect, known as photothermal deflection works by 'bending' light beams away from a surface towards your eyes.
"It's similar to what happens when hot air above the ground 'reflects' a watery image of the sky instead of allowing light beams to bounce off the ground. This creates the illusion of pools of water that torment thirsty travellers in the desert."

Researchers from the University of Dallas said carbon nanotubes could be heated extremely rapidly, creating a sharp "heat gradient" similar to a layer of heated air above the ground.

"The extremely high heat-transfer ability of these transparent carbon nanotube sheets enables high-frequency modulation of sheet temperature over an enormous temperature range," they said.

"The remarkable performance of nanotube sheets suggests possible applications for switchable invisibility cloaks."
Carbon nanotubes are a man-made form of carbon that forms hair-like carbon "tubes" that can be millions of times longer than their diameter, The Mail said.

"Nanotubes are formed from 'rolled' tubes of graphene - atom-thick sheets of carbon.
"They are sometimes used in bicycle components or high-strength resins, but the material also has extraordinary heat-conducting qualities - used here to create 'invisibility' at the touch of a button."

oh and I used the search function to find this thread ;D

I wouldn't have enough mana to do this.

[Santa]

Cool. They'll be able to sneak up and kill us invisibly. I'm stoked.

[joboo]

All my dead relatives are invisible, apparently they like to watch me masturbate.

[TheNocturnalEgyptian]

I would honestly be disappointed if certain consortiums did not already have optical cloaking.

How would they be able to see where you are?

If they're invisible to you because the light you see is "bent" around them, it would seem to me that no light would actually strike them. If no light actually strikes them, how could they see light reflected off of you, as it would also "bend" around them.

Fuck if I know...but then what's new? Just the same old vampire tricks. They've been doing that same shit since the 8th century, Transylvania. :)

Invisibility cloak makes tanks look like cows. (http://www.wired.com/dangerroom/2011/09/invisibility-cloak-tanks-cows/)

British defense company BAE Systems has developed (http://www.baesystems.com/Newsroom/NewsReleases/autoGen_1118592745.html) an “invisibility cloak” that can effectively hide vehicles from view in the infra-red spectrum.

http://www.wired.com/about/wp-content/gallery/partner_logos/partner_wireduk.gif (http://www.wired.co.uk/)

The patented system — called Adaptiv — uses a matrix of hexagonal “pixels” that can change their temperature very rapidly. On-board cameras sweep the area to pick up the background scenery and display that infra-red (http://www.wired.co.uk/news/archive/2011-06/22/controlled-hover-test-flight) signature on the vehicle.
This allows even moving tanks to be effectively invisible in the infra-red spectrum, or mimic other objects. “The tank skin essentially becomes a big infra red TV,” BAE Head of External Communications Mike Sweeney told Wired.co.uk. “You can display anything you want on it — including a cow (http://www.wired.co.uk/news/archive/2011-06/29/un-declares-rinderpest-is-gone) — while the rest of the vehicle blends into the background.”
The current system works in the infra-red spectrum, which could hide vehicles from heat-seeking missiles, drones and heat-sensitive goggles. However, BAE Systems engineers have combined the pixels with other technologies to provide camouflage in other parts of the electro-magnetic spectrum (http://www.wired.co.uk/news/archive/2010-11/09/ofcom-white-space-broadband).

“Earlier attempts at similar cloaking devices have hit problems because of cost, excessive power requirements or because they were insufficiently robust,” explained project manager Peder Sjölund. ”Our panels can be made so strong that they provide useful armor protection and consume relatively low levels of electricity, especially when the vehicle is at rest in ’stealth [reconnaissance]‘ mode and generator output is low.”
The pixel panels can also be made at different sizes to achieve practical invisibility at greater ranges. The resolution needed to hide a CV90 tank (http://en.wikipedia.org/wiki/Combat_Vehicle_90) at close range is high, but disguising a building or warship from a great distance can be achieved with a lower resolution, and larger panels.
In tests earlier this summer, BAE systems has been able to make one side of a Swedish CV90 tank “effectively invisible” in infra-red mode, and will be showing this off at the UK Defence and Security Equipment International exhibition later this month (Wired.co.uk will be attending). Over the next few years, the company hopes to see similar success in other parts of the electro-magnetic spectrum.

Yawn. GS-US has had an invisibility cloak for a long time! Just go into settings, click General Settings, and at the top click "Invisible Mode On". It keeps Henny Penny from finding me and nagging about fixing the leaky faucet when I'm posting here!

Always one step ahead of TPTB Hehehe! ;D
