Vertical Axis Wind Turbine/ VerticalAxis Windmill  V.A.W.T system is an advanced Vertical Axis Wind Turbine System ( Patent No.200420081310 ) of efficient and nice-looking. The set-up power is from 200W to 100KW. The vane is made on the principle of the wing of the aircraft while the structure is made on the principle of vertical wirlwind which is of the advantage of no influence caused by the winddirectgion. This efficiency of electric energy production is 18% higher than the horizontal wirlwind generator being used at present. This system is of a position-fixed system, hence the electricity transmiission wire will not be stranded in operation. Such system is of a silent Vertical Axis Wind Turbine, thus makes it possible to be installed at any places including in some bad locations like on the roof of the house, on the boat, in the snow area and on the lighthouse and in the sea or river area. Such system is developed to replace the old system used at present. The old system is of the horizontal wirlwind. In operation the face of the vane of such old system is heavily pressured by the strong wind which will easily cause the vane deformed and which will definitely cause the heavy noise and the reduction of the turn speed and the deficierncy of electric energy production.
