Magnetic 'Spin Battery' Announced

  1. Mar 12, 2009 #1
    Has anybody heard of this concept?


    Somebody seems to have now actually shown one in practice. A magnetic 'spin battery'.

    Can anyone tell me if this thing is supposed to be capable of greater energy storage density than a conventional chemical battery? Is it capable of even having greater energy storage density than a chemical fuel cell?

    What kind of energy density should it have, in Wh?

    no, it's all voodoo to me. a primer on spin would actually be nice.

    So far, the lab prototypes hold up for 10 minutes, or so, before self discharging. I think that's what I read...
