3. “Renewable energy”- Any sustainable energy source that are replenished on a human time scale. Example , neutral sources Like., Sunlight, Wind, Rain, Tides, Waves, And Geothermal Heat, etc., However with the progress of humanity also came, a rise in the demand of energy resources. Led to over-exploitation of non-renewable resources and many problems associated with them. A need for developments in renewable energy technology Wind is the fastest growing energy source in the world and one of the lowest priced renewable energy in todays technologies. Introduction

4. LITERATURE SURVEY SL. NO TITLE AUTHORS VOLUME/ EDITION SUMMARY 1 Magenn Air Rotor System (Mars ) Kamini N.Shelke,et.al (2012) Vol.2 Author said that MARS is a lighter-than-air tethered wind turbine that rotates about a horizontal axis in response to wind, generating electrical energy. 2 Electric Energy Generation by Magenn Air Rotor System (MARS ) Rakesh Chaudhari (2015) Vol.4 MARS is most effective, cost effective, eco friendly, mobile, low maintenance way of generating electrical energy out of wind energy.

5. 5 SL. NO TITLE AUTHORS VOLUME/ EDITION SUMMARY 3 MAGENN AIR ROTOR SYSTEM (M.A.R.S.) Dhilipkumar ( 18 July 2013) Author Magenn Power Air Rotor System  (M.A.R.S.), helium filled wind generator that rotates around a horizontal axis and sends electricity down a tether that can be used immediately, stored in a battery or routed to the power grid. 4 Flying Electric Generators as Alternate Source of Energy Sanket P. Wankhade,et.al (10 oct 2018) Vol.5 In this paper author side that Flying electric generator are proposed to harness kinetic energy in powerful, persistent high altitude winds

6. WHY WIND ENERGY? Renewable Source of Energy. Reduces dependency on fossil energy supply. Contributes to a healthy environment. Cost effective energy solution It‘s Sustainable 6

7. It is a windmill similar to a conventional one in its working principle but here the rotor and generator will be floating in air just like a hot air balloon CANADIAN ENGINEER FRED FERGUSON. Specialized in airships, proposed an innovative system called as Magenn Air Rotor System (MARS). Magenn’s design is radically different from other windmills on the market it would not use propeller blades. Instead, it would be a helium blimp, with Sovouries -style scoops causing it to rotote around motors at the attachment-points to its tether. WHAT ARE FLYING WIINDMILLS?

8. Magenn air rotor system Magenn air rotor system The altitude being the main factor of wind energy if the height of the wind mill is increased then the efficiency of the plant can be automatically increased. This step would encounter serious problems. The problems would be More capital cost. Overall increase in size of wind turbine. Increase in maintenance cost. To solve the above problems the idea of M.A.R.S have been developed which can be easily understood by a phrase “a flying wind turbine ”

9. Thus the idea of a flying wind turbine came into existence by some major modifications based on basic principle of a conventional wind turbine. The magenn air rotor system does not contain a tower which forms a major restriction to increase the height of wind mill. Just floats in the air as a gas balloon and generates energy by means of rotating wind turbines placed inside it.

10. Construction of MARS The MARS is constructed with Composite Fabrics used in Airships. the fabric will be Dacron with an inner laminated coating of Mylar to reduce porosity and an exterior coating of Tedlar which will provide ultra-violet protection. MARS is filled with helium gas, which is inert and non-flammable. For, a 10KW system, helium of about 10.500 cubic meter s required. 10

12. LIFTING MECHANISM The Helium gas creates a additional lift force that is in excess of the total weight of the system. The helium provides at least twice the positive lift versus the overall weight of the MARS unit. Additional lift is also created when the rotor is spinning in a wind. The aerodynamic effect that produces additional lift is called the Magnus Effect Magnus Effect: This effect was discovered in mid-1800’s that creates Lift when a spherical or cylindrical object is spun while moving in a fluid. The combined lifting effect from buoyant ( hetium ) lift and aerodynamic (Magnus) lift help stabilize the Air Rotor against “leaning” in the wind. In tests, on Air Rotor went straight up and held a near vertical position in various wind speeds, since the Magnus effect increases as the wind speed increases. Research indicates that maximum lean will never be more than 45 degrees from the vertical

13. WORKING The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. Utility-scale turbines range in size from 50 to 750 kilowatts. The wind rotates the turbine at a speed of 30 to 60 rpm. A reduction gear box is provided to increase the speed to 1200 to 1500 rpm for the generator to produce electricity. The wind turns the turbine which spins the generator and the Electricity Is Generated. This electricity is sent to ground by the tether and can be consumed readily, stored in batteries for later use or can be supplied to grid.

14. ADVANTAGES Low cost electricity. Wide range of wind speed. Natural resource of energy. Ability to install closer to power grid. Can used like mobile since we can take it from one place to another. Ideal for off grid applications or where power is not available. Bird & bat friendly. Lower noise.

15. LIMITATIONS MARS units cannot be installed within five miles of the boundary of any airport. Initial cost is high. As output power is dependent on wind speed so, it gives varying output. The drawback of the technology is that the balloon has to be re-filled with helium every 6 months, seeing as the gas leaks. Another disadvantage of floating windmills is that, they have to be taken down in extremely powerful winds, whereas common wind turbines are simply shut down.

16. Applications Off grid for cottages and remote uses such as cell towers and exploration equipment. Developing nations where infrastructure limited or non existent. Military applications. Rapid development to disaster areas for power to emergency. And medical equipment, water pumps and relief efforts.

17. Conclusion MARS is most effective, cost effective, eco friendly, mobile, low maintenance way of generating electrical energy out of wind energy. It would be an ideal for the country like India which is having varieties in geographical landmark to implement such power stations as it could be installed where it could be. It is the best solution for the power-crises faced by the world.
