Invisibility cloak created in 3-D

WOW!! How cool is that. Allthough I'm sure some of you will agree a little scary also

Ahhh I see the confusion here.

The technology I have pointed to uses meta materials to bend light around an object.

The technology you are pointing to is just a clever staged way to show the effects of invisibility.

Check this to learn more about metamaterials



here is a demonstration of how the cloak works based on results.



And here is what it could do if it were to be perfected.



See now why we are so excited about this? and why its an important news story??

All the best,

Korg.

Imagine being able to cloak say? Buildings on the moon or mars
Would explain the dodgy pics?
bending light and trying to take an image of it? interesting

Or even better build on the dark side of the moon and use meta materials to bend light around so the dark would be light if you see what I mean??

great.....maybe ill finally be able to get to see inside the female changing rooms at the baths

hahahaha an obvious one... but seriously this tech could be used for crime...

I mean who is going to get caught if you are invisible??

Maybe this will spawn a whole new department of the police, ICID - invisible criminal investigation department

all the best,

If these scientists wanted to know how to make gold disappear, surely the cheapest & easiest route would have been to pick up the phone and give Gordon Brown a call.

It's scary where this technology is taking us and it will no doubt be abused. I expect fake terrorist attacks will go through the roof once this technology becomes available, that's if it doesn't already exist.

Make it a cream and you'll have the world's most effective sunscreen!

Downside is no-one would actually see you at the beach...

Seriously though, I could see tons of uses of being able to bend light. But it seems outright silly that only a team of 4 relatively young scientists would be working on it. Since this could in fact revolutionize modern warfare, I would think different nations and private armies were having a bidding-war right now.

Well, If I had had this tech in highschool i can think of a certain locker room that would have become a target

Yes. It would be interesting. But you don't really even have to do that. You can use simple camo for it, and they do it a lot already. In the hunt to build the first nuke, they had built entire cities underneath a false landscape that was picture perfect from above.

The real awesome idea would be being able to cloak items in the atmosphere/space by controlling nano's that are actually in the upper atmosphere. HAARP would be a great way to achieve this.

I think that the military has had this tech for a while now, so think that the only reason its finding its way into the public domain is just a logical step with the common knowledge and experimentation with meta materials at university level.

I think as the video above suggests that this technology will trigger a 'photonic revolution'.

Image covering your wheels on your car or bike in this kind of tech... Would make you look like your car or bike was hovering But then how would you know when it’s time to change a tyre??

I'm guessing that this tech cannot work in some instances... the light needs to have the ability to go around, so my earlier suggestion of covering your wall may work for a building on the outside but you couldn't cover your internal wall in the stuff and see through it as the light has nowhere to go around to... if you see what I mean?

I see the fashion industry making a killing out this... a bit like the emperor’s new clothes.. But image having a nice warm thick coat that actually looks like it’s just a small jacket because parts of it are cloaked so to speak??

All the best,

Korg.

Well for one thing I can see this technology being used in the security industry quite extensively. One of the key rules in securing property or information is to first make it difficult to locate. Thats why floor safes and vault doors in oppulent private dwellings are often near impossible to find unless you know where to look. This technology could be used to mask expensive items, or entrances to sensitive areas in both the well to do home, and corperate offices of the worlds rich and powerful in the short term. In the long term you could see this being used by police on stakeouts and so forth.
And I guess where the benifits end, and the uses end, would depend on the sort of surface area that this tech would remain effective on. If the best they can do is give you say , five square meteres then maybe it stops at covering a door or a safe on the wall, but say they can get it effective up to 25 to thirty square meteres, well , you could wrap a whole BUNCH of stuff in invisibility. Whole vehicles, portacabins, sheds, I mean seriously the possibilities are quite far reaching. I think alot depends on the physical limits of what can be hidden with this stuff. Can it be mobile and still provide good cloaking ? What scrutiny would it hold up to ? How reliable is it under weather, wear and tear, and what are its energy requirements. Also , whats the user interface like ? Will it be fully adaptive, or require constant recalibration by a proffesional user? These are all things I would have to know more on before compiling a comprehensive list of possible uses.

From what I can understand of this technology the energy requirements for this technology is non other than manufacturing process. As the negative refraction is a result of the material itself rather than the result of any mechanical or electronic system.

In other words it doesn't require power to work.

I also think it would be interesting to know how effective this will become, will be able to create zero distortion etc? and how will deformations in the material if it can be applied to material effect the refration ect...

I'm thinking along the lines that this material will only be effective on hard flat surfaces as opposed to flexable surfaces... but who knows... it's early days yet.

Where there is a will there is a way..

All the best,

Korg.

I read this and it was very interesting. They made invisible a little bump on a piece of gold in 3-D, which is truly amazing. I hope the ind. mil. complex doesn't keep it under wraps and it makes it to the Consumer market.

Thanks for the post.

Thanks for clarifying that for me . I suppose then that there are both pros and cons to this stuff.
You say that this material does not require a power source in order to produce the cloaking effects and if this is the case, then its far more useful than other cloaking methods that have been discussed in recent years. However, if it can only cloak relatively flat sided , uniform objects, then that will reduce its versatility. For instance, this would make it unsuitable for masking the presence of a person, being as we are, a rather strange shape from a geometric point of veiw. Also , the military will not be able to use it to cloak man portable heavy weapons due to thier interesting shape.
I would love to see this material demonstrated. This subject has always fascinated me to a large degree, mostly due to its implications, but also as a practical excersize in impossibility !

Awesome! You know this will never be available to the general public. Some day soon a troop of 20 men will be able to sneak up to you in broad day light and haul you off without you or anyone else seeing. Yes, I'm super glad they are developing this .

o.O I want to see it! Just kidding. I find it interesting that cinema has influenced science to this point. Such films as Star Wars and perhaps with such a cloak Harry Potter, have pushed the minds of science to make new novel ideas.

Yeah I don't think it will be possible to say cloak an uneven surface such as a motorised gun turret or something, but....

It would be possible to have a flat shield with a small hole where the mussel of the weapon could be.. then it would shield the weapon..

Though I think it is more likely that the munitions would be cloaked such as a cloaked cruise missile or drone spy plane / missile.

Incidentally I saw a documentary a few months back on drone craft and the interview took place where they showed how they control the drone. The cool thing was they had rigged the controls for the drone up to a playstation controller. So they were actually flying this thing as if it was a video game..

Maybe another use could be to store munitions in plain sight so to speak. One of the major problems with fighting units is the munitions supply, but if you could dump store munitions actually inside a zone of operations and then cloak it, you could replenish the men on the ground much easier.

Or what about the negatives??

Image cloaking a nuke in a city... right in the centre of a city in plain sight but cloaked??

The military aspects of this technology are so many...

I wonder though if this technology could be used for other things other than invisibility.

If they are able to control the flow of light so precisely, does that mean higher efficiency in any object that requires lasers to work? Wouldn’t this mean we could focus light far more efficiently??

I wonder if that means better telescopes. Would we be able to look further out into the cosmos using meta-materials as lenses?

I wish there were some experts on this material here who could explain a little more about what the other uses would be.

A photonic revolution... sounds so post - futuristic.

I would love to see this material demonstrated. This subject has always fascinated me to a large degree, mostly due to its implications, but also as a practical exercise in impossibility !

Having been an avid reader and quantum physics enthusiast over the last 10 years I can say with all finality that nothing is impossible, just varying degrees of improbability.



All the best,

Korg.

It could be used quite effectively to hunt Arnold Schwarzenegger and Carl Weathers through a Central American Jungle...
