Now you see me, now you don't

Researchers from the University of Kansas outfitted a six-and-a-half-foot drone with an "electroluminescent surface" -- a material that lights up in response to a current. Then they took a pair of pictures, when the drone soared to a thousand feet. The left picture is with the electroluminesence system off, the right was taken with it on. Squint hard, and you'll see the difference - the drone is a small, gray blotch in the middle of the left frame.

Rico says technology like this can only piss off the little countries, who'll have to steal it since they can't afford to develop it...
