With the biggest anchor to progress of truly seamless mobile technology being the battery it is encouraging to read this article which outlines the discovery of a completely new way to store energy. It does not involve chemical reactions and could offer much greater engery density than current solutions. As an additional benifit this came technology could be applied to data storage allowing for solid state magnetic drives.

The device created by University of Miami Physicist Stewart E. Barnes, of the College of Arts and Sciences and his collaborators can store energy in magnets rather than through chemical reactions. Like a winding up toy car, the spin battery is "wound up" by applying a large magnetic field --no chemistry involved. The device is potentially better than anything found so far, said Barnes.
