Abstract
The Savonius rotor was initially developed as a wind turbine. Here, we present power data for use of the rotor as a water current turbine. The data is presented in nondimensional form. Two different geometries and two different sizes were tested in water and in air. The data shows that for the Savonius rotor the scaling laws work and so can be used to predict prototype behaviour
