Star Trek fans might be hoping we have a cloaking device ready for the Klingons and Romulans. According to an article on Fox News' tech page, the answer is yes. Invisible tanks, planes, and armor could be in use within 5 years. Rather than the whole "bending light" theory, this tech would use cameras and a high tech display to project the surrounding environment onto the hull of the vehicle rendering it effectively invisible - similar to a chameleon blending into the surrounding.
One thing I found cool is that I use a tech like this in my draft sci-fi novel, but not for military applications. The tech is used on the roof of an flying limousine and effectively makes the roof disappear so the occupants can stare at the stars. I one-up it by adding some touch-screen tech (like an iPad). Touch a star visible and get the info on it.
With this new tech coming out, I may have to tone down the surprise or make a comment that the characters hadn't heard of the tech used on anything besides military vehicles. Something to incorporate the science facts of this tech. Regardless, it's cool to see this tech really coming about. It's one of the great things about sci-fi. Things we dream can become reality.
