savonius wind turbine - Google-haku  Eräs mitoitusehdotus Savoniukselle  Unfortunately, Savonius wind turbines typically only have an efficiency of around 15% - i.e. just 15% of the wind energy hitting the rotor is turned into rotational mechanical energy. (This is much less than can be achieved with a Darrieus wind turbine which uses lift rather than drag.)
