The past is the future (of batteries)!

A team of researchers at Massachusetts Institute of Technology are redeveloping the capacitor to be better in most every way than the standard battery.  This new capacitor could be charged in seconds rather than hours, and would last much longer than standard batteries.  Problems with capacitors in the past have been due to their storage capacity being proportional to surface area.  This has been overcome by covering the electrodes in the battery with millions of tiny nanotubes, thereby increasing the surface area.  The article refers to a bath towel soaking up more water than a bed sheet due to it’s greater overall surface area.  A prototype is expected within the next few months.
