SAVONIUS WIND TURBINE
A wind turbine, of the savonius wind turbine type, comprises a rotatable member extending along a longitudinal axis and a plurality of blades extending radially outwards from the rotatable member and spaced apart around the circumference thereof. The rotatable member is arranged such that, in normal use, the longitudinal axis extends in a substantially vertical direction and the blades travel around the longitudinal axis. The wind turbine further comprising a wind deflector operable to deflect wind to provide a sheltered region for the blades as they travel towards the wind and thereby substantially reducing the drag induced on the turbine.
