ABSTRACT:
A vertical axis wind mill with retractable sails comprising a central core which has vertical side walls in a generally cylindrical configuration. The core has an upper end and a lower end and a drive shaft positioned along the central axis therefor. The drive shaft has an upper end and a lower end. The core also has curved vanes extending radially outwardly therefrom for rotation under the force of the wind to rotate the core and the drive shaft. The device also includes a fixed support which receives the shaft through bearings to allow for rotation of the core while the upper support remains fixed. Also included is a housing with a generator located within the lower extent of the housing beneath the core. The generator has an upper end secured to the lower end of the shaft for generating electricity in response to rotation of the shaft. The sails are radially retracted by coiling up into a lower portion of a U-shaped bracket, with a drive system for raising and lowering the sails.
