is it just me?or is this something more than a "water battery"?

the most interesting thing to think about is how this creates a current...

well,what i was referring to is that at some point during the process the water is split into hho,hydrogen and oxygen,then turned back into h2o.

not necessarily. By aligning the ions or even the polarized ends of the water molecules you would end up with a positive charge at one end and a negative charge at the other end. Sort of a water electret. But since in a water solution it is usually the electrolyte which allows current to flow and there isn't any electrolyte in this device there must be another process. It could be that electrons enter at the OH- end and are pased from water molecule to water molecule and then exit at the H+ end. I found it interesting.
