Rainbow power do micro-hydro generators. You need a good flow, & fall: about 1 atmosphere pressure for every ~10M drop. But you need to take losses into account. A friend built a hydro using a 3 phase motor: think he got ~ 300W from it. He used the Rainbow impeller (that he actually got from the developer, before Rainbow sold it I think.)
Try googling micro hydro systems. regards Doug On Saturday 29 September 2007 04:51:22 pm Bob Molloy wrote: > Hi all, > I'm exploring the possibilities of minor hydro power in my local > area from waterfalls, lake outlets etc. but need a good rule of thumb for > calculating the power potential.
