Invisibility cloak

Think of the civilian uses of this nifty little garment. You'll never see another RADAR trap on the road 'til its too late. You won't see all those cameras watching you or the criminal sneaking up on you.

Infra-red sunglasses. Always keep one in your pocket.

As soon as they make infra-red goggles as small as sunglasses, that is.

Very interesting. I wonder how much energy is required to 'bend' light.

The initial headline-grabbing experiment was done here on Duke's campus. The question of how much juice it uses is a good question, but I can say that the initial experiment did not draw enough to flip anything off on campus, which is directly hooked up to a Duke Energy power plant (aren't things convenient when the institution you attend owns half of the surrounding area/infrastructure?).

It also doesn't say about the size of an experiment; it might be on a molecular level, although even on molecular level to accelerate molecule to near speed of light requires enormous energy.

Actually IIRC it talks about 'invisibility' in April 07, Scientific American. Doesn't seem same thing though. Here's quote:

"...the cloaking device would be a thick shell constructed of metamaterials, which exhibit unusual optical properties. This shell could bend electromagnetic radiation around its central cavity,..."
