New "nanoantenna" material sucks heat from any source to cool devices, generate electricity
Engadget — ... the sun, earth, or even your PC's warmth. The antennas can be tuned to different parts of the infrared spectrum, and the thin material can be sandwiched together to cover the full desired range. Unfortunately, the resulting current generated alternates at rates too high to be converted to DC with current technology -- new manufacturing processes will needed -- but once that problem is solved, nanoantennas should easily best solar cells in efficiency and production costs.

Nano Skin to generate power by absorbing Earth Rays
Fashionfunky.com — ... (coated in this skin) is leave it out of the pocket at any time - day or night - visible light or not. Another application of the nano skin is cooling objects such as microprocessors which have traditionally had a heating problem. As heat typically is emitted as IR rays from many objects, the antennas could cool objects by collecting these rays and reemitting them at a harmless wavelength. This could be used on a large scale, or on a smaller scale for computer component cooling. Source
