Researchers Tout Electricity Storage Tech That Could Recharge Devices In Minutes

Posted by samzenpus on from the but-I-want-it-now dept.

coondoggie writes "Vanderbilt University researchers say they have come up with a way to store electricity on a silicon-based supercapacitor that would let mobile phones recharge in seconds and let them continue to operate for weeks without recharging. The Vanderbilt team said they used porous silicon -- a material with a controllable and well-defined nanostructure made by electrochemically etching the surface of a silicon wafer. This let them create surfaces with optimal nanostructures for supercapacitor electrodes, but it left them with a major problem: Silicon is generally considered unsuitable for use in supercapacitors because it reacts readily with some of chemicals in the electrolytes that provide the ions that store the electrical charge, the researchers said."

      Be a little patient.

      It's taking a while to teach editing to the dolphins with their new Minority Report-style interfaces.

      Also, between the data caps and the slow GPU progress, there's almost no band left. And the NSA is using most of that to monitor Chancellor Merkel's mobile phone, which, coincidentally, is powered by a silicon supercapacitor.

      It's taking a while to teach editing to the dolphins with their new Minority Report-style interfaces.

      The twin inverted post repeater (TWIPR) approach uses the same technique as dolphins do to capture page views. Like dolphins, Slashdot editors post two times in quick succession to cancel out background noise. This finding, as demonstrated by this duplicate post, explains how Slashdot editors post two times in quick succession to cancel out background noise.

      Yeah. You laugh now, but one day they'll manage to reduce the interval to minus 6.5h and publish the dup hours before the fact has even happened.

    To find, first thing on the front page - a nice nifty dup. Glad to see nothing has changed. ;)
