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?
