I know nothing about the topic, but this comes to mind: the mechanical energy of moving water. When I rub a comb through my hair in low humidity conditions, I can generate sparks. It doesn't seem implausible that water flowing past some alloy might cause some small fraction of H2O rubbing against it to split via some electrical or chemical process.

There's the magnetohydrodynamic effect, which can be used for propulsion[1], guess the reverse should generate electricity? edit: Hunch correct[2]. Off course requires magnetic field, and while naturally magnetized rocks exist AFAIK, not sure how strong they are.
