    in my engineering class this year we made a backup lighting system in case of power failure using capacitors. Granted, we were limited to .8 farads, so we couldn’t power nearly that much, but going by what I see there it looks like you could power some LED’s for quite a while

    I’ve always wanted battery free remotes. How about induction coil wireless charger and aerogel caps as battery substitutes.

    How about flipping them on ebay for $20 a piece as some high tech lifetime universal cmos battery replacement kit?

    Just draw off the hd power rail for contiuous recharge.

    I think an army of BEAM robots is in order! Light-tracking ‘photopoppers’ … turn on the lights and the tiny bot army comes to life seeking the brightest light. Just goto http://www.solarbotics.com for the rest of the gear.

    a solar powered, sling back(right term?) charger/power storage using said supercapacitors. have the sling backed electricity run through a usable/working bug zapper designed to take the load, and slowly feed the capacitors at a safe rate. that way you can have a bug killing, electricity making, energy machine. could charge batteries with it if im thinking about it right too. make it portable, so a person could transport it to where ever bugs need a genocide, and voila. awesome use of super capacitor.
