Star Trek tech No. 9: Cloaking devices
How do you know the Romulans and Klingons were truly badass? Because they had cloaking devices. Since the early days of the Stealth bomber (pictured), the U.S. military has been seeking ways to make its own warbirds less of a target. Using metamaterials not found in nature, scientists at the Karlsruhe Institute of Technology have developed cloaking tech that can bend light, heat, and sound around objects. Unfortunately, the current iteration of the cloak is thinner than a human hair. The next challenge: Figuring out how to build really tiny star ships.
