If $H_2O$ ions have a net electric charge and electric current is the flow of electric charge, can a stream of water ions be considered an electric current? If so, is it conceivably possible (not necessarily feasible) to use a flow of water ions in place of a copper wire carrying an electrical current in an electrical circuit? For example, in a bizarre Rube Goldberg contraption sort of situation.
Edit: I guess this question applies to any sort of ion in either gas or liquid state. I don't know enough chemistry to know if $H_2O$ ions are even a thing that exist in the real world
