I am planning a small waterfall inside my new greenhouse project. The water will be gathered and treated in a tank ten feet about ground level. The water will originate from run-off water that I capture, but once inside it will be pumped up from the lowest of my two pools. The entire system will be about 6,000 gallons in total.
Part of the use of the pond/waterfall is for solar mass. It will help keep the temperature moderated day and night. It is also for esthetic purposes and I want to light it and use a couple of fountains. I thought that I could use the energy of the small waterfall to power to lights and fountains for the water system. I know I won't get a lot of energy, but every little bit is good, otherwise I'm wasting it.
So, I am looking for advice on a tiny hydro generator I can either build, or get locally. No expensive hydro-systems, the energy recovery isn't worth it.
Anyone got advice for a newbie?
