ya, it's all a matter of energy density for the caps. a group of MIT scientists have made ultra caps with energy density of 60Wh/kg, NICE.

Better yet EStor has a capacitor with if im not mistaken, 120 Wh/kg? Don't quote me on that, i'll have to look it up again.

For my setup, 232 grams for a 38.75 Farad, 20 volts cap bank is pretty fair. i've emaile Maxwell Technologies for a price quote on the caps.
