The Earth doesnt emit any rays, or so you thought. After being baked by the sun all day long, infrared rays are emitted by the earth even at night. By making a nano skin that specifically targets this wavelength of rays, scientists have been able to ensure that the nano skin is able to keep on producing juice even at night.

Engineers are now working on converting this absorbed energy to electricity. Once that is succesful all you need to do to charge your cell phone (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.
