I invented an invisibility cloak ten years ago. Unfortunately I put the plans in the pocket of the cloak, been looking for it ever since I put it down somewhere...

Based on the photo, it seems that while the object is hidden, the \"cloak\" itself is visible. That would seem to limit the practical uses a bit, don\'t you think? It\'s an interesting exercise, but I don\'t think teenage boys will be using it to sneak into the girls restroom anytime soon.

Now you c-rystal it, now you don\'t!



Perio....blame it on the cloak!

Brill!!!

@bobmeyerweb:

That is a remarkably shortsighted comment. The military potential of this technology, even in its *current form*, is simply overwhelming. Imagine a platoon of units closing in on your location, but you can only tell that \"something\" is approaching - you can\'t even know whether it\'s infantry or armour! This is the sort of thing that can decide world wars, nothing short of the atomic bomb.

Gizmag gets a blue ribbon for having the first popular article about this kind of tech in the last decade that doesn\'t mention Harry Potter.

It will be intersting to see the next step : Embedding Calcite nano crystals in a metamaterial cloak ... Calcite will block things sideways and metamaterial the rest or multiple layers of nano-calcites reducing the size of the seen object to minimal some mild metamaterial input ....Intersting.

That is a remarkably silly comment. A giant wall made of cardboard could do exactly that in a military situation, and doesn\'t break when it gets shot. I am fairly sure that cardboard does not have the same destructive power as an atomic bomb, nor will it win any battles. This trite idea of military use is currently much too complicated, even from a geometric standpoint.

This article screams for a video clip. That would make it much clearer what\'s supposed to be invisible and what\'s not. It\'s hard to show what\'s hidden AFTER you hid it, unless you show what it looked like BEFORE you hide it.

Seems to me magicinas have been rendering things invisible for a long time. Nothing new here.

While non sequiturs are a great deal of fun to imagine up, they are useless if you\'re trying to make a point. A giant wall of cardboard? This has nothing to do with an invisibility cloak. Your conclusion does not follow. Also, it is incredibly naive of you to say that invisibility will not win any battles. The art of being hidden, believe it or not, is an enormous tool that is decisive in battles, one example being the sniper. jules_c does have a point. Take the destructive power and psychological power that one sniper can create, multiply it, and you have a fantastic advantage. As to your claim that using this technology is too complicated, I reply with a question-when has a revolutionary advancement in science ever been EASY to use when it was first developed?
