INTRODUCTION:

INTRODUCTION Wind is a clean, renewable energy source. Wind's eco-friendly power can help to reduce the environmental damages. Following are some important properties for today’s energy need: Eco-friendly Cost-effectiveness Mobility of the power station (Ex. In Rural areas, Sea, Desert, etc) Efficiency of the power station Low installation cost, running cost and maintenance 3

Wind at high altitude:

Wind at high altitude At low altitude (below 400 feet), wind has low speed and is non-steady. At higher altitude (600-1000 feet), wind has high velocity and is turbulence free. At high altitude wind is more persistent, so capacity factor for wind turbine can increase. 4

Conventional wind turbine:

Conventional wind turbine A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. The towers range from 60 to 90 metres (200 to 300 ft) tall. They are efficient and highly reliable. 7

Limitations of conventional wind turbine :

Limitations of conventional wind turbine Wind below 400 feet have low speed and are not steady, so turbine’s efficiency decreases. Can be installed only at specific geographical locations where sufficient wind speed is available. The productivity of a wind-power system depends heavily on the prevailing weather. Wind turbines produce noise. 8

Floating Wind Turbine (FWT):

Floating Wind Turbine (FWT) Anchored by tether at high altitude (1000 feet) Have large cylindrical balloon filled with Helium Capable of producing electricity at any wind speed between 5 - 65 mph Generated electricity is transferred from balloon to transformer via. tether Rudder at centre stabilizes it and direct it towards the wind Rotation causes Magnus effect which gives additional upward lift 9

Materials Used:

Materials Used Tether Made of Vectran , strongest plastic composite materials in the world does not stretch or absorb water, nor does it fractures when you bend it Balloon envelope made of polyurethane, a high-strength woven cotton fabric resistant to UV damage, scuffing and abrasion Helium inert, non-flammable and lighter than air creates a lift force that is in excess of the total weight of the FWT 13

Weather and Lightning effect:

Weather and Lightning effect Tether and balloon envelope are strong enough to bear bad weather conditions FWTs are equipped with lightning arrestors In case the unit breaks loose from the tether or base, a rip cord type device cuts a hole in the envelope and the FWT unit safely floats back to the ground (instant deflate device) 14

FWT Specifications:

FWT Specifications Size (Diameter x Length) 45 ft x 100 ft (plus blade height of 22 ft each) Rated Power 101,000 Watts Weight Under 13,000 lbs Volume of Helium 200,000 cubic feet Tether Height 750 ft standard - up to 1,500 ft optional tether length Start-up Wind Speed 2.5 m/sec - 5.6 mph Cut-in Wind Speed 3.0 m/sec - 6.7 mph Rated Wind Speed 12.0 m/sec - 26.8 mph Cut-out Wind Speed 24.0 m/sec - 53.7 mph Maximum Wind Speed 30.0 m/sec - 67.1 mph Temperature Range -40¼C /-40¼F to +45¼C/+113¼F Generators 100 kW Total Output Form 380 V 3 Phase 50 Hz, 480 & 600 V 3 Phase 60 Hz or Regulated DC Life Cycle 10 to 15 Years Price (Estimated) $500,000 USD (approx. ₹2,50,00,000) 15 Source: http://www.magenn.com/products.php

Advantages of FWT:

Advantages of FWT Deliver time-averaged output much closer to its rated capacity Can be placed closer to demand centres, reducing transmission line costs and transmission line loses Can operate in wind speeds between 5 – 65 mph can be raised to higher altitudes without having to build an expensive tower can be easily moved to different locations 17

Applications of FWT:

Applications of FWT Can be used off-grid for cell-towers, exploration equipment, communities, farms and factories Can be rapidly deployed to disaster areas for power to emergency and medical equipment, water pumps, and relief efforts Wind farm deployment For military purpose Can provide off-grid combined wind and diesel solutions for island nations, farms, remote areas, cell towers, exploration equipment, backup power and water pumps for natural gas mines In developing nations where infrastructure is limited or non-existent it can easily provide electricity 18

Environment Concerns:

Environment Concerns Visual Impact Highly visible structures often opposed by homeowners or real estate developers owning land near a proposed site Opposition often diminishes after they realize their environmental benefits Avian Mortality Birds and bats occasionally collide with wind turbines FWTs are three-dimensional, softer objects. Birds and bats will more easily be aware of the turbine's presence Noise Generated noise can be reduced through improvement in rotor design 21

Conclusion:

Conclusion Conventional windmills are approached their maximum energy extraction potential relative to their installation cost. FWT is the efficient, cost-effective, eco-friendly, mobile, low maintenance way of generate electrical energy out of wind energy. It could be one of the solutions for the power-crises faced by whole world. FWT also need further development in design and materials to make it more efficient and cheaper 22
