>And surge current!

Olin, only the special (i.e. $pecial) supercaps are capable of high
current. The normal ones normally found in consumer equipment and on the
shelves of retailers don't. Please trust me on this, I did some study on
the matter and the conclusion was that NiCd or Lithium cells beat them in
price, volume, and availability. This was not that long ago.

A 1F supercap will appear as a good quality (but inductive) 0.1uF
capacitor when examined with 'normal' C-meter instruments. It reaches 1F
when discharged at under 100uA (5-10uA is better).
