That's pretty good; that 2cc device is providing 2 Wh of energy in
~5500 mm^3 of volume.  A 9V alkaline provides ~5.85 Wh (~650
mAh) in ~18000 mm^3, or less than 3 times the power in more
than 3 times the volume.  And I'd be willing to be it has a much
flatter discharge curve, too.

Can't wait to take one of these things camping!
