Subject:      Savonius rotor and water well
To: mailto:DEVEL-L@AMERICAN.EDU


Hi folks,


as I'm new to this list, I don't really know what's going on, but in the meantime I have some questions. The background 
s that I'm trying to put together a housing project for homeless people here in Mexico, and one of my concerns is, how t
 pump water from a (to be drilled) well. As you can see from the subject line, I'm thinking about a Savonius rotor, conn
cted to a pump with a vertical shaft.


Now, my questions are:
        - does anyone know where to get these pumps?
        - anyone knows an efficient and cheap design?
        - how should I calculate the surface area of the rotor?


Any help is greatly appreciated.
