Ivan: Francis is not a Turgo.
Look into Turgos, easier to build, there are some manufacturers in South Africa Francois Swanepoel [EMAIL PROTECTED] maybe still producing Bankis in south Africa Calculate around 2500 to 5000 installed KW ( variations due to the engineering work). Around 1000 dollars per KW looks OK ( Turbine, generator and controller), though make sure that the generator is a BRUSHLESS Type. Can you down load large files ?. http://microhydropower.net/download/layman2.pdf 10 MB long good hydro manual http://microhydropower.net/download/bestpractsynthe.pdf may be good for you as well.
