Finnish invention, a vertical axis Savonius wind turbine can be further improved according to doctoral thesis of Svetlana Marmutova from the University of Vaasa.
Due to the mechanical modification of the rotor the power coefficient was shown to be increased by around 8 percent (2% units). The power coefficient is the ratio of the power extracted by the rotor to the available kinetic power in the air flow.
