I used to work with a guy that built a ram pump to water his garden that was uphill from a creek. It seemed impossible that something like that could work. If I remember it would take in so much water and a portion of that was shot up through a hose.

And also for my pond but never carried through, I bought plans from a guy in Ireland to build a three bladed wind turbine fastened to a brake drum generator that you wound an armature and placed rare earth magnets around the inside edge of the drum housing to produce electricity for a pond aerator. So good luck on your project, I can identify with that.
