ABSTRACT:
Floating wind generators are the new dimension for the generation of power by converting the energy of conventional air currents in the atmosphere at high altitudes for the generation of electricity and power with the help of MARS technology.
MARS (magenn power air rotor system) is a Wind Power Anywhere solution with distinct advantages over existing Conventional Wind Turbines and Diesel Generating Systems including: global deployment, lower costs, better operational performance, and greater environmental advantages.
MARS is a lighter-than-air tethered wind turbine that rotates about a horizontal axis in response to wind, generating electrical energy. This electrical energy is transferred down the 1000-foot tether for immediate use, or to a set of batteries for later use, or to the power grid. Helium sustains MARS and allows it to ascend to a higher altitude than traditional wind turbines. MARS captures the energy available in the 600 to 1000-foot low level and nocturnal jet streams that exist almost everywhere. MARS rotation also generates the "Magnus effect" which provides additional lift, keeps the MARS stabilized, and positions it within a very controlled and restricted location to adhere.
INTRODUCTION:
The Magenn Power Air Rotor System (MARS) is an innovative lighter-than-air tethered device that rotates about a horizontal axis in response to wind, efficiently generating clean renewable electrical energy at a lower cost than all competing systems. This electrical energy is transferred down the tether to a transformer at a ground station and then transferred to the electricity power grid. Helium (an inert non-reactive lighter than air gas) sustains the Air Rotor which ascends to an altitude for best winds and its rotation also causes the Magnus effect. This provides additional lift, keeps the device stabilized, keeps it positioned within a very controlled and restricted location, and causes it to pull up overhead rather than drift downwind on its tether.

MECHANISM OF MARS
All competing wind generators use bladed two-dimensional disk-like structures and rigid towers. The Magenn Power Air Rotor system is a closed three-dimensional structure (cylinder). It offers high torque, low starting speeds, and superior overall efficiency thanks to its ability to deploy higher. The closed structure allows Magenn Power to produce wind rotors from very small to very large sizes at a fraction of the cost of current wind generators.
DESIGN PARAMETERS OF MARS
Computational Fluid Dynamic Simulation allows Magenn Power to simulate various designs quickly and efficiently without the need to build or test hundreds of prototypes in an actual wind tunnel.

With the Magenn MARS "Wind Power Anywhere" technology, there are less limits on placement of our wind turbines as we are able to get into the "low level wind jet streams" that exist the higher you go in elevation. The 270 meter wind map clearly shows that most areas of Ontario have winds above the 8 m/s range when you get to a height of 270 meters.
MARS technology of a tether versus a tower enables more areas around the world to utilize wind power.
FLOATING WIND TURBINE INSTALLATION AND DEPLOYING:
1. Its easy to install and deploying the FWG.
2. To setup a wind turbine it takes nearly about few minutes.
ENVIRONMENTAL CONCERNS:
These are usually the main environmental concerns that arise in association with the set up of a wind turbine.
1.Visual Impact
Wind turbines are highly visible structures often opposed by homeowners or real estate developers owning land near a proposed site. Several studies have shown that opposition often diminishes after the turbines are in place as homeowners find the structures aesthetically pleasing and realize their environmental benefits. Thus, opposition related to visual impact can be reduced through careful arrangement of the wind turbines, rendering them impressive against a landscape and through the education of the benefits of wind energy. Less opposition arises in rural settings where farmers are often paid rent or fees by the owners of the turbines.
Magenn Power has an added benefit in that our MARS units may be deployed much higher above surrounding terrain than conventional systems, thus capturing more wind. Conventional systems are positioned in areas where winds are higher such as coastal areas and high terrain. These locations are typically at greater distances to customers. MARS, due to it ability to reach greater winds at higher altitudes can be placed closer to demand centers, reducing transmission line costs and transmission losses.
2.Avian Mortality
Birds and bats occasionally collide with wind turbines, as they do with other tall structures such as buildings. However, collisions with Magenn's Air Rotors should be significantly less.
Birds and bats tend not to fly into objects directly in front of them. Birds can see these objects and bats can sense them. Current terrestrial wind turbines are large fast-moving blades slicing through the air, hitting birds and bats from the side without the animals sensing the presence of blades. In contrast Magenn wind turbines are three-dimensional, softer objects. Birds and bats will more easily be aware of the turbine's presence.
A large number of studies have addressed this issue. The findings indicate that overall, bird deaths due to wind turbines are low, especially when compared to other manmade structures. An extensive literature review was conducted and a comparison of annual avian mortality in the United States was presented. The table outlines the results.
