Researchers from the University of Texas at Dallas, correctly using the unique physical and electrical properties of carbon nanotubes and optical effect, whereby in the desert or the sea can be seen mirages, created a kind of underwater invisibility cloak — a device that can hide objects by a simple movement of the lever of an electrical switch.
The developed technology is not yet ready to integrate into the diver’s wetsuits and spy equipment, but a working demo copy of this «fabric», the effect of which you can see in the video below, gives hope for a very speedy appearance of working prototypes. Underwater invisibility cloak in his work uses light rays refraction effect is exactly the same, which causes a mirage in the desert. This effect occurs at the boundary of the mass of air or water, with a significant difference in temperature.
Precisely because of this people often can see in the desert nonexistent water. What they see is actually a reflection of the sky, but because it is near the surface of the earth and has a blue color, the human brain finds that he sees water, writes DailyTechInfo. The same effect can be observed in action video in the illustration below. Using conductive carbon nanotubes, carbon tubes whose walls are one atom thick, on the surface of the sheet of transparent material, it is possible to quickly heat the water near the surface of the sheet material to a high temperature.
