I already have.... Some Crystal Cell battery's in series, running a variation of the Joule Theft Circuit lighting a couple hundred+ LED's in camping lamps. Just add water, and you have a real Energizer Bunny.... I know Small Scale, but proves the point.... Too bad one cell broke during the move, and will need to be fixed before i can use the setup again on a camping trip....
