Apparently the "supercaps" hold their charge over a long period of
time.

I find those sizes very hard to believe. Even a one farad capacitor is
pretty large and in some cases, larger than an average flashlight.Depends upon the working voltage. I had seen 1 farad caps 20 years ago that
were not much larger than a couple of small mercury cells. I'm sure they've
gotten them even smaller by now.

BAD,

"The existence of a One-Farad Capacitor {Super-Cap}
is due to modern materials development and is now
useful for general experiments."
Size : This Capacitor is only 2.9cm in diameter and 2.5cm high.
