Sam: Your site seems a very hard one. Things for water catchment goes for conduct the water aside the natural stream, if it is possible to do that. Propeller turbines are for low head (some 1,5 - 5 meters). Your idea looks bad for me, because you must have "control" on the water flow always, at normal/low flow time and with floods flows also. Please look at www.powerpal.com for some views about picohydro low head propeller turbines and how can be mounted. Scale the sites shown, in your mind for larger propeller as per the power you need. Other greater 'S' type propeller turbines can be see in www's from Orengine, Ossberger or KWV, among others. Kind regards,

My name is sam. and iam a newbe. hmmmm sounds like an aa meeting. I have looked at all the past post for the last year and a half,some good info. But nothing for my situation, So here we go. I have a stream that at low water is 4ft deep,8ft wide,moving at 6ft p/s between two large rocks. problem,in winter(rainny season)these numbers are tripled. I cannot use a dam. so I believe I must anchor a prop. to the bottom of the stream. I know there are machines out there but they are to large, and trying to extrapolate from pictures has not worked,trying to get info from prop builders has been fruitless. The questions are, 1 should I be looking at one large prop or several smaller ones?. 2 Were can I find a design for a prop that is turned by water?. 3 Am I going in the right direction?. Best regards to all Sam. Does your company feature in the microhydro business directory at http://microhydropower.net/directory ?
