Perhaps only in the movies would you hear something about an invisibility cloak. But battery powered? It can only get interesting.
And it seems that researchers over at the University of Texas in Austin are on to something, a battery-powered cloaking device which is said to be something that would boost invisibility.
By using existing invisibility cloaks, ones that make use of metasurfaces to deflect and refract light, adding batteries into the mix is said to boost the signal and ensure invisibility in all kinds of conditions.
Don’t get your hopes up though. The said cloaks are still a concept/theory although a prototype is said to be up and coming.
