This document discusses a Buoyant Airborne Turbine (BAT) that uses high altitude winds to generate electricity. The BAT is a helium-filled doughnut shape that floats around 1,000 feet in the air, holding a wind turbine. It is tethered to the ground and can generate enough power for over a dozen homes. BATs take advantage of winds that are 8 times stronger and more consistent at high altitudes compared to near the ground. They have benefits like lower installation costs than tower-mounted turbines and can be rapidly deployed. However, safety during bad weather and public acceptance of large floating devices are challenges.

3. INTRODUCTION
Renewable energy is energy which comes from natural resources such
as sunlight, wind, rain, tides, and geothermal heat, which are renewable.
Buoyan airborn turbine worked by using high altitude wind energy
,which is 8 times stronger than low altitude wind.
BAT is one of the classification of Air born wind turbines.
BAT is float about 1000 to 2000 feet in the air.
It produce 30kw of energy.

4. WIND POWER
Wind power is the conversion of wind energy into a useful form of energy,
such as :
*wind turbines to make electricity,
* wind mills for mechanical power,
*wind pumps for pumping water or drainage,
*used to propel ships
Wind energy has been the world’s fastest growing source of electricity
during the past decade, with over 20% annual growth

5. AIRBORN WIND TURBINE
• Those Turbines which float in air, with a rotor supported in air,
attached to a tether.

6. TYPES OF AWT
Ground-Gen systems - In which the conversion of mechanical
energy into electrical energy takes place on the ground.
Fly-Gen systems - In which such conversion is done on the aircraft
in the air.

7. TYPES OF FLY-GEN AWT
Plane with four turbines
Aircraft composed by a frame of wings and turbines
Buoyant Airborne Turbine
Static suspension quad-rotor in autorotation

8. An airborne wind turbine is a design
concept for a wind turbine with a rotor
supported in the air without a tower
Known as the BAT — or Buoyant
Airborne Turbine
white helium-filled doughnut
surrounding a rotor will float about
1,000 feet in the air
feed enough electricity to power more
than a dozen homes through one of the
cables tethering it to the ground

9. BUOYOANT AIRBORNE
TURBINE
Airborne wind turbines may
operate in low or high altitudes
An aerodynamic airborne wind
power system relies on the wind
for support.
Tether reeling speeds and
directions can be adjusted in
response to tether tensions
9
10. WORKING
Turbine starts rotating due to
the flow of wind through the
blades.
By this way the generator also
starts rotating, since the
generator is coupled with blade.
The energy produced in
generator is stored in battery
which is placed at ground
station, by connecting with high
tension wires.
This stored energy can utilized. 10
11. HIGH ALTITUDE WIND
Winds at higher altitudes become steadier, more persistent, and of higher
velocity.
High altitude winds are more consistent and average around twice the
velocity, with five to eight times the power density, than those found near
ground-level.
11
12. In the U.S. alone, over 60% of potential wind sites for tower-mounted
systems were found to be uneconomical.
High altitude winds are one of the largest untapped renewable resources
in the world
Power increases by the cube of wind speed.

14. COMPONENTS
Shell - A proprietary helium-filled shell made from low weight,
industrial fabrics that lifts the turbine up and stabilizes it in the air.
Turbine - A lightweight conventional four blade, horizontal axis wind
turbine fixed within the shell.
Invertor: Used for converting to DC into AC for external power
supply
Generator: An AC generator is used for converting mechanical
energy into electrical energy

15. COMPONENTS
Ground Station - The portable ground station is
rapidly deployed from a shipping container and
includes an autonomous control system and power
conditioning equipment
Tethers – The lightweight, high strength tethers hold the turbine in
place in all weather conditions and transmit power to the ground.

16. BENEFITS
High Capacity Power
1. Operating up to 600 meters, the Airborne wind turbine generates over
twice the energy of similarly rated tower-mounted wind turbines.
2. The power output from high altitude winds is smooth, consistent, and
easy to integrate
Siting and Impact
1. It minimizes human and environmental impact when compared to
conventional tower-mounted wind turbines.
16
17. Automated and Reliable Operations
1. Optimize energy generation
2. Manage the docking of equipment to protect it during severe
weather.
Low Cost
1. Floating turbine reduces the installation and transport cost by up to
90 percent, as it does not require a tower, crane
17
18. Mobility and Rapid Deployment
1. Easy transport, setup, and redeployment
Additional Revenue from Airborne Services
1. It provides additional services like communication, surveillance, and
sensory equipment
2. It provides a line of sight over 60 miles in any direction, offering a
powerful platform that fixed towers cannot reach.

19. DISADVANTAGES
Bad weather in the form of thunder and lightning strikes pose very
serious risk to the destruction of any airborne device.
No power is generated if the device is retracted during bad
weather
Safety hazard as the airborn devices and power cable may become
detached or damaged falling to the ground.
Public acceptance of these large floating airborne devices over
land and residential areas.
Electrical energy losses in the long conducting cable from the
airborne generating system to the ground.

sectors:
Rural communities
Island and arctic communities
Mining and Oil & Gas sectors
Agriculture sector
Entertainment sector
Military sites
