Improved High-Performance Energy Storage

Physicists at the University of North Carolina have developed new improvements for high-energy-density capacitors that can store up to seven times as much energy per unity volume as common capacitors. "The amount of energy that a capacitor can store depends on the insulating material in between the metal surfaces, called a dielectric. A polymer called PVDF has interested physicists as a possible high-performance dielectric. It exists in two forms, polarized or unpolarized. In either case, its structure is mostly frozen-in and changes only slightly when a capacitor is charged up. Mixing a second polymer called CTFE with PVDF results in a material with regions that can change their structure, enabling it to store and release unprecedented amounts of energy."

Wrong University

From TFA, it is North Carolina State University. You are about to be set upon by wolves!

Great...

Now first year EE students are going to actually *die* when they forget their cap is still charged.

It was bad enough to just get your shiny new needlenose pliers welded together. =/
