I'm toying with the idea of building a domestic hydro electric generator. The basic premise is a wind powered pump to elevate a body of water to a header tank, which then drives a pelton wheel as it discharges to an ideally lower-than-ground-floor reservoir.
Has anyone done any work to determine what amount of energy might be recoverable in any real-world scenarios? Further, has anyone looked into what sort of COTS equipment might be available for such a project?
I'd be interested to hear what you think, especially with regard to bottlenecks in terms of both cost to build and efficiency on the other end, once built. There are many ways to skin this cat, and I'd like to think about finding a good balance between capital cost and energy return.
