Disclosed apparatus enables us to harvest wind power in high altitude atmosphere by taking advantage of kite, airfoil and dual purpose circular fan. The kite keeps the wind power turbines floated at high altitude when wind power is sufficient enough to sustain them. With help of stepping motor, the circular fan can be positioned either in vertical or horizontal position. In former position, the fan drives wind turbine to generate power as it is in angle of attack. In latter position, the turbine is converted into electrical motor with power provided from external source. It drives the fan providing floating forces when wind speed is too slow to keep the apparatus floated only by the kite or while the apparatus is ascending or descending.
