Puff... (invisibility cloak)

''Call it what you will -- the world's first 3D nanoantenna or an invisibility cloak -- but a new metamaterial created by Rice University scientists could hide objects from human sight.
Practical uses for the nanoantenna go beyond hiding things.
Solar collectors reflect light on a single point, but to work at maximum efficiency they must be mechanically tilted to stay in line with the sun as it moves across the sky.
The new nanoantenna would concentrate light on a single point without having to mechanically tilt it, eliminating one of the biggest costs involved in solar panels.

Metamaterials rule!
