Abstract: Wind – an energy source that is available almost everywhere. The force of the wind, harnessed using wind turbine system is admirably suited for power generation. Maximum availability of the wind turbine system is secured through the perfect interaction between the various products and systems. The cost of crude oil is continuously increasing hence the need to find alternative energy sources. One source is harnessing the power of wind which does not harmful for environment. Usually, wind turbines are fixed to the ground and can only reach up to height of125 meters. There are also issues with the consistency of the wind speeds and direction at these heights. Wind turbines installed at these heights do not produce as much power as they could due to the inconsistency of the winds. The goal of this review paper is to enlighten the way to elevate the turbines up to heights of 300 meters and above using a lighter than air structure. At this altitude, the wind speeds are more constant and the direction of the wind does not vary. These two factors can significantly improve the turbines operating efficiency and hence can increase maximum potential. Many steps were involved to reach these goals. To start off, a preliminary design of the structure including the support beams, tether and turbines was created. The summation of the forces from weight and drag associated with the structure were found. These numbers were needed to determine the volume of helium required to overcome the total weight. With the drag forces calculated, the strength of the tether combined with the angle formed between the tether and ground were determined. The turbines are aligned facing backwards so they do not interfere with the tethering system. Wings were added to provide additional lift to reduce the amount of helium needed.
