My micro-hydro has worked fine for several years with minimal trash screening. Recently, I have had the turbine nozzles blocked with dead frogs. Now I know that Egypt was plagued with them when Moses was around but they have suddenly appeared in the stream that provides the water for the turbine. They have never been present before. So, this hill stream and its surrounding area seems to have warmed up significantly enough to make the habitat suitable for frogs. Proof of global warming ? The trash screen has had to be extended over the top of the forebay to stop the blighters jumping in and commiting suicide David www.OffTheGrid.co.uk ------------------------ Yahoo!
