In this invention, some unique blades are embedded which start from the top of the glass dome, extend around it and ending up below the dome plate. All of these blades are used to slow rotation of the tower. This vertical wind turbine, while rotating the structure to see the various views and landscapes around the tower, provides the electrical power required by the penthouse from wind power by the generator. Three blades are embedded in the top of the turbine, which is the upper part of the main blades. Lower and inside the container in roof of dome, the gearbox and generator are located to which harnessed energy by blades is transferred.
