How to Become Invisible

mdm42 writes "Looks like a theoretical physicist at St. Andrews University in Scotland believes that invisibility may be possible. And its not going to be a potion or a cloak, but will come in the form of a device. " Let's just hope that when the invisible woman arrives, she's played more convincingly than Jessica Alba.

Old news! Wired ran this story three years ago. The technology isn't any more advanced now than it was then. Military.com published an extremely informative guide to invisibility last year. Much better than TFA.

It would depend on the conditions, though - in a rural setting, letting 95% of the light through would be fine at any reasonable distance (20-50 ft or so) - the slight distortion of colors or bending of a line isn't too easy to spot when colors are gradient and lines are curves.

In an urban setting, though, you'd be more likely to notice the distortion around a 95% invisible object if it was passing between you and a straight line, like the edge of a building, or making one portion of the car across the street appear a different color.

But combined with current stealth techniques (sticking to shadows, stay in buildings, etc.) this would be a tremendous advantage to the equipped force. Probably not quite as much as, say, power armor, but DARPA's got money going into that, too.
