A Finnish invention, a vertical axis Savonius wind turbine can be further improved shows a new study. 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.
