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."

    The world's most dangerous person commutes the sentence of one of his
    brownshirts.

    And you chipheads continue to talk about iPods, iPhones, and Winbloze.

    Scooter ASSHOLE libby was just pardoned by BUSH.. That fucking CRONIE. yes he will have to 'ay a fine' which by all accounts he has plenty of money from lobbying.. Fucking shit. The fallout guy gets off scott free while the real criminals are still in office. Fucking shame. No other persons sentance EVER gets commuted right off the bat.

    Paris Hilton? HAAHAHAHAHAHAA No pardon for her, make an example out of that bitch!!

      Cute post. Not technically correct, however: Bush has commuted Libby's sentence, which may be considerably different than a pardon.
