what you could do is make one of those SE's on beam-online that turns on in
the dark and hook up a led flasher circuit instead of another motor or
circuit!

what if we could make a bot with a tiny hydro-electric plant inside! then we
could really call it an aquavore!

either provide electrolyte (like the salt water) or water to activate
the dry electrolyte. Quoting from a webpage I once saved:
"The first electric cell is believed to have been developed by an
Italian scientist, Alessandro Volta, in the late 1790's. His cell, known
as the voltaic pile, consisted of a stack of zinc and silver disks
separated by cardboard disks moistened in a salt solution. One can get
similar results with copper pennies, filter paper and aluminum foil."
So technically you are consuming more than just water.
