Pretty cool.. It only works if you're looking at it directly from the side, but still impressive.

Wow, maybe a (somewhat) invisible cloak really is possible in the future. Also, stunts like this are why I love science!

It's not if it's possible, but when it's possible..there are ways to make this camera and projection technology 100x smaller, so it would be even harder to see the difference between the car and background..add some microscopic lights to that and you can almost let the sun light go right threw you, so the front doesn't project your shadow..
in the future helicopters and tanks and soldier are almost invisible

I don't think this would make a very efficient invisibility cloak though. Since it uses LEDs, it will only work if you are looking from exactly the right direction. If you are looking at it from say a 45 angle, then you will see a displaced image. Now, this cloak (http://www.youtube.com/watch?v=kR4e2G0NAcQ) on the other hand looks a lot more promising. It creates a mirage which conceals an object.

in theory that could be used on the plates of a tank... but looking at that not for a long time. that idea would only work on flat 90* surfaces which would affect the silhouette of the vehicle and make it more vulnerable to anti-Armour weapons if it was mounted directly onto the Armour plating due to the huge design change they will have to go through.

but looking at it if you suppose they adjust a design like the Amphibious Sherman (a rubber skin on a frame around the tank) than can be deployed and erected either by the crew or automatically it would make for some pretty impressive ambushes. but the idea is flawed, it would leave the driver blind and unless the turret had a separate one the gun would not be able to move so it be a one use wonder before running away and laying up again

^ And let's not forget our old friend dirt and mud which can and will coat the vic and basically render the camo worthless. It was impossible to keep our MATVs clean in Afghanistan even if you stuck to the roads so I couldn't even begin to imagine what a nightmare it is for tank crews - especially if you're working in a wet and sloppy environment.

Because nano is so small the camera's and screens could be made in different postitions within one square cm, or panoramic, or hollow..filming the front and projecting the back..but they probably invent something even more crazy, by just bending the image around an object..there's allready a nano product invented to deflect mud water and even oil and honey..

this tank is in a way invisible

you realize that Armour only makes the tanks THERMAL signature disappear? it requires the tanks crew to be able to aptly hide it using traditional camouflage methods. it is NOT invisibility its designed to counter the thermal eqipment used in tracking and deployment of modern anti tank missiles and reconnaissance flights

the video before is pure speculation. you forget that they have only made that tiny spot of fabric at the cost of several million pounds. it it nowhere near military application and i would argue it never will be unless they can truely deliver what they are claiming at a applicable funding level

I can't shake the feeling we had this exact discussion already :-).

Mean, it also only works if you are the right distance away so it neatly demonstrates why see-through (invisibility cloak) optical camo is near enough a physical impossibility.

Take anyone of those shots and move closer or further away and the image portrayed will be out of line with the background. It will be too big or too small.

This type of camo can only work if the object using it knows and can track where the observer is looking from so it can portray the correct image that it is obscuring. Even if you got that bit solved (highly ulikely) then you only need to add a second observer at a different distance and the camo is defeated.

In the advert the crew know where the second camera is so know where to zoom the camera capturing the image.

i know the tank isn't invisible, that's why i said" in a way invisible".
the fabric is expensive now, but that wil change as soon as they tweeked it..it's only another way of creating a cloack
Soul is right though, we could do this over and over..until one of us has acces to places like area 51, it's all speculating..

It's a cool tech demo, but the military applications are seriously limited. It relies on LED's, which are Light Emitting Diodes. As a potential target, the last thing you want to be doing is emitting light. I think color-changing fabrics and other materials are a much more likely scenario for military use. These materials already exist in some form - both in heat-sensitive or triggered via electric current.
