Green Technology Airborne Wind Turbines
[attachment=65543]
Abstract
the airborne wind turbine is the next generation of wind turbines which is currently in development process. This windmill doesn’t require axis or tower and is capable of producing greater and constant current. The turbine is actually suspended high in the air where the wind speed is high. While the conventional wind turbines appear to harness only 30% of the total wind, airborne wind turbines harness about 54.5%. Challenges include safely suspending and maintaining turbines hundreds of meters off the ground in high winds and storms, transferring the generated power back to earth, and interference with aviation.
INTRODUCTION
Day after day, the desperate need of power is increasing, India hoped to find the answer by opening the Koodam kulam Nuclear power plant which has the capacity of generating 2000MW of power. But, the power cut problem hasn’t ended. One of the many ways to solve this problem is the airborne wind mills. These wind mills can be set up in the middle of the farm or on a building roof top or in the shores of the sea. They have the capacity to generate about 2500MW of power when operated in a large scale. Its works based on the fact that wind gets stronger with the increase in altitude. Hence they are more productive and more efficient than the traditional wind mills.
PRINCIPLE OF OPERATION
The principle behind any windmill is that the wind passes through the airfoil section which rises the fan. This produces torque which is converted into electricity. It is basically the conversion of the wind energy into the mechanical energy of the turbine and then finally to electricity

POTENTIAL OF AIRBORNE WIND TURBINES
Researches show that the current extractable power from the wind energy is greater than all the power sources together put. Axel Kleidon of the Max Planck Institute in Germany carried out a "top down" calculation on how much wind energy there is, starting with the incoming solar radiation that drives the winds by creating temperature differences in the atmosphere. He concluded that somewhere between 18 TW and 68 TW could be extracted. Cristina Archer and Mark Z. Jacobson presented a "bottom-up" estimate, which unlike Kleidon's are based on actual measurements of wind speeds, and found that there is 1700 TW of wind power at an altitude of 100 meters over land and sea. Of this, "between 72 and 170 TW could be extracted in a practical and cost-competitive manner”. They later estimated 80 TW. These researches refer on the energy obtainable from lower altitudes.
As the wind gradient gets higher with altitudes, the estimated extractable power is assumed to 380 TW. According to the survey conducted at the end of 2012, India generates about 2,336 MW of power from traditional wind turbines. But the survey states that the true potential of India is 18,481 MW. With proper utilization of the wind energy, the power demand can be subdued.
ADVANTAGES AND DISADVANTAGES
• They produce the same power as that of TWT for about half the cost.
• Since they are conceived to higher altitude , they have access to winds with higher velocity and consistency
• The construction costs are 90% lesser than that of the conventional turbines. They are way cheaper.
• The installation process is easier.
• They require lesser maintenance.
• Lesser maintenance refers to lesser maintenance personnel, which reduces maintenance costs further.
• The airborne wind turbines allows for deployment outside of environmentally sensitive locations.
• They occupy about the same space as that of the conventional wind turbines.
SUGGESTIONS
The government must also focus on setting up and expansion of the laboratories to promote the non-conventional sources of energy. Severe steps must be taken in order to gain control of the power crisis. Private industries should be given the license to take over the Electric boards for quicker recovery from the crisis.
CONCLUSION
The recent researches tell that NLC can operate only for another 300 years. We have depleted our resources and are supplied with plutonium by Australia. The conventional sources of energy cease to exist in time. Going along with the green and non-conventional technologies happen to be solution to the problem we laid upon us. Wind energy has broken its limits and can be one of the suitable solutions to the problem. The government must consider these new valuable expansions in this energy crisis and must help for the betterment of the country. Resources at hand must be greatly considered rather than importing
