I see what you mean, can you show me how you calculated that to get those numbers?

I don't see how it'll be a terrible waste of money. I mean a PMA is going to cost around $200, the impleller is $100, I already have a pump (20FT head/120 GPH). The pump uses 18w of power so anything generated after that is free power.

I could easily build one of these things (that retails close to 2 grand by the way) from home depot:

I saw this pic and thought if I could built a small scale hydro-power turbine to experiment with.



I basically want to buy a PMA (permanent magnet alternator), connect a pelton turbine (pic below) and use a pump to drive it in a closed looped system.



The power this will make depends upon what kind of pump I have on this, right? Has anyone does something like this bfore. Having this run all day, everyday will generate a good amount of power with the right parts (that's where I need some help). Can you guys recommend some good parts to build something like. I would eventually like for this to generate enough power to run my computer and offset the pump power.

By the way, this is my first time with things like this.
