Hyvää päivää! I'm Sigurd Johannes Savonius. Architect, inventor and environmentalist. I invented the Savonius wind turbine, a type of vertical-axis wind turbine (VAWT) used for converting the force of the wind into torque on a rotating shaft named after me, which will help the environment a bit further. Perkele Saatana, isn't it beautiful? Well, you're free to say something, junior.
