You read that right- (2). In August I wrote about a different invisibility cloak, one that was bending light rays around objects to make them so they couldn’t be seen. The latest invisibility cloak is not meant to trick your eyes, but to trick sensors, specifically, heat sensors. So yes, it’s more of a heat shield than an invisibility cloak, but the purpose is really the same.

Of course, what it seems like we’ll really use this thermal diffusion ability for is to make our computers run quieter, by getting make them cooler and therefore eliminating the need for fans.
