The Magenn Air Rotor System (MARS) is the next generation of wind turbines with cost and performance advantages over existing systems. 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 tether for consumption, or to a set of batteries or the power grid. Helium sustains the Magenn Air Rotor System, which ascends to an altitude as selected by the operator for the best winds. Its rotation also generates the “Magnus” effect. This aerodynamic phenomenon provides additional lift, keeps the MARS device stabilized, positions MARS within a very controlled and restricted location, and finally, causes MARS to pull up overhead to maximize altitude rather than drift downwind on its tether. It’s become mandatory rather than option to go for the renewable source of energy today in the whole world. The system Magenn air rotor system (M.A.R.S.) is one of the types of Offshore Wind Turbine. This kind of turbine is lighter than the air. It uses the wind power to produce electric energy. The reason why it is possible to stay in higher level of atmosphere is the Helium that is used to fulfil the turbine. This helps the turbine to be in areas where wind has higher speed, than on the lower levels of atmosphere. This way is produced more energy from the wind power, which is transferred to the surface transformer station using the cables. It has a lot of advantages comparing to the conventional OWT (Offshore Wind Energy) e.g. low cost of produced electric energy, lower noise, turbine is placed in higher location, lower constrains where it can be placed, high mobility level, and it is not required to use a heavy-duty machine. The OWT M.A.R.S can be taken out higher over the surface than the conventional systems, so it can catch more powerful wind. The most suitable areas are in national parks, areas far away from the consumers of the electric energy, which raise up the energy losses during the long-distance power transmission.

2. WHY WIND
ENERGY?
• Renewable Source of Energy.
• Reduces dependency on fossil energy
supply.
• Contributes to a healthy environment.
• Cost effective energy solution

4. What is MARS?
 Generation electrical energy by using MAGNUS
effect
 A spinning object is moving through the fluid
departs from its straight path because of the
pressure differences that develop in the fluid as
a result of velocity changes induced by spinning
body.
 The Magnus effect is the manifestation of
Bernoulli’s theorem fluid pressure decreases at
points where the speed of the fluid increases

5. Why MARS?
MARS is a lighter-than-air tethered
wind turbine that rotates about a
horizontal axis.
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.

Balloon Generator
Wind
Vane
Stabilizer
Ropes or
Wires

8. BALLON:
• The balloon is cylindrical in shape and is filled with helium air which is
lighter then air, hence it could be placed above 300m height.
• A Helium balloon is a balloon that stays aloft due to being filled with a
gas less dense than air or lighter than air. Helium balloons work by the
same law of buoyancy.
GENERATOR:
• It the actual machine which converts the rotary motion into electrical
energy.
• There are two conventional generator used for power generation. And
transfers power to the base station unit.
WIND VANE STABILIZER:
• It is one of the important parts of the air borne turbine. It restricts the
turbine in horizontal direction, and gives stability to the balloon.
ROPES AND WIRES:
• Tethered rope (Kevlar, 450Kg tensile strength) 4.46 Kg per Km
• Ground and provides the electric link between the balloon to local
power network and the ground based power and control station, which
is connected to the grid

10. 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.

being filled in the inflatable structure.

12. LIFTING MECHANISM:
• The Helium gas creates a 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 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.

15. FEATURES OF MARS:
• It offers high torque, low starting speed.
• Low transmission loss.
• Operable between 2 m/sec and in excess of 28 m/sec.
• Quick installation and needs no crane or tower for
lifting purpose.
• No noise
• Reliable winds
• Less expensive power.
• Superior overall efficiency.
• Altitudes from 400-ft to 1,000-ft above ground level are
possible

16. CABLE: MATERIAL
• The cable must perform two essential tasks – it
must be strong enough to hold the balloon, and it
must conduct electricity
• The cable is made up of a twisted Vectran core
composed of 330 individual strands of Vectran.
• Vectran is one of the toughest plastics on the
planet.
• Can withstand extremely high heats.
• It is very resistant to chemicals and moisture.
• Good abrasion resistance.

20. LIMITATIONS
• MARS units cannot be installed within five
miles of the boundary of any airport.
• Initial cost is high.

21. CONCLUSION
• This Kind of technology can reduce our Dependencies
on Fossil Fuels which are Depleting at a rapid rate.
• As there is no Pollution in this system Green Energy
can be produced which can reduce green house gases.
• As it can be near Demand centers cost on Power lines
is reduces.
• If this technology is implemented it can eliminate
power problems of all Nations in coming years.
