Just got this on the news and thought everyone else here would be interested in this . Not sure how it works but first of its kind today they tell everyone they got it working . For some time people have been trying to come up with invisibility cloak by some how bending light waves around. > [@](#): > > Canadian camouflage company claims to have created perfect invisibility cloak, US military soon to be invisible > > A Canadian company called Hyperstealth is reporting that it has developed Quantum Stealth, a material that renders the target “completely invisible by bending light waves around the target.” If the mock-up photos are to be believed, Quantum Stealth basically works like Harry Potter’s invisibility cloak.

Canadians are pretty much invisible in the first place, so it’s nice to see one of us about to make a profit from it. ---

“It is completely invisible. Here are some photos of it.” Why does this put me in mind of other current “[Canadian](http://boards.straightdope.com/sdmb/showthread.php?t=675621)” thread? ---

This seems… doubtful, especially if the material needs some kind of electric power. Of course, as a Canadian, I may have been required to say that. ---

I have been reading about developments in this area but on a very small scale. The photo doesn’t seem real. How does the cloak know that when it bends the light, it should do it so that the grass field shows but the human doesn’t? ---

The media loves stories like this. Invisibility cloaks have been announced for years with little to show in the end run. Technology like this is advancing, but it’s like jet packs and flying cars. They’re dreams whose reality is impractical, for now, but may one day change our lives. ---

> [@RaftPeople](#): > > I have been reading about developments in this area but on a very small scale. The photo doesn’t seem real. Yes - it’s been done with a small ring, that only worked within a limited range of wavelengths. For objects as big as a human, for the whole visible spectrum, it’s practically impossible. The article is a load of tripe. ---

If you look at the video, it seems the picture of the girl in the invisibility cloak is a still shot – not a video. That tells me the technology has a long way to go. Another problem – seems to me that an invisibility cloak can be easily defeated by a heat sensor. If technology improves to the point where invisibility cloaks are really good, I guess it will be very easy to carry around a very light, sensitive heat sensor which lets you easily bust someone in an invisibility cloak. My other guess is that before it becomes practical to put a soldier in an invisibility cloak, it will be cheaper and easier to have a remote control device do whatever it was that the soldier was supposed to do. ---

Quote from the article: > [@](#): > > All of the pictures that you see here, and on Hyperstealth’s site, are mock-ups, because “for security issues we can not show the actual technology.” In other words, “It’s not actually really even remotely close to working, but we can’t admit that, because then we wouldn’t get any [del]suckers[/del]investors.”. If it really _did_ work, there couldn’t possibly be any security issues with showing real pictures.
