Nanotechnology Mirage Effect

Researchers at the University of Texas Dallas recently demonstrated that transparent carbon nanotube sheets, which can have the density of air and the specific strength of steel, can be used to make objects invisible.

WOAH!!

This news is a couple of weeks old but somehow I must have missed it.

Their website goes on to say:

“This invisibility for light oblique to the nanotube sheets is caused by the mirage effect, in which a thermally generated refractive index gradient bends light array from a hidden object.”

Okay, so it only works on the oblique, so you’re not going to use this to sneak up on anyone anytime soon, but this still blows my mind.

Of course, the research is being funded by “Office of Naval Research, NASA, the Air Force Office of Scientific Research”. Uh huh. Invisible battleships, anyone? I hated playing BATTLESHIP as a kid.
