    Yes but I think you will need to tell the readers what size capacitors and chager you have.

    To be honest the energy stored in Capacitors isn't that great you would need a true monster to drive an LED for say an over night light.

    If it was that easy the cheapo solar cell Lights for the garden would get rid of the batteries as they are a pain to charge propperly

    Personally though I think I would make a spot welder with them to weld like battery terminals and the likes.

    Or at least  fun stuff  like imploding cans !!
