pass electricity with zero resistance and make stuff float. Superfluids have zero viscosity and can climb vertical walls to escape containers. Supercapacitors
? Well, they don't do anything quite so dramatic, but they could result in batteries that charge faster and hold more charge than ever. Capacitors in general have to run a balance between capacity and fast charging, but these fancy ones with diamond-shaped nanopores in zeolite-templated carbon, developed at Tohoku University
in Sendai, Japan, are said to offer the best of both worlds. How good? Cellphones that charge in minutes, electric cars with longer lasting batteries, and free Superman Underoos for all. Naturally there's no word on when these things might actually escape the lab and show up in real batteries, but you already knew that, didn't you.
