4. INTRODUCTION:
Wind energy is the fastest growing source of clean energy worldwide. A major issue with the
technology is fluctuation in the source of wind. There is a near constant source of wind power on the
highways due to rapidly moving vehicles. The motivation for this project is to contribute to the global
trend towards clean energy in a feasible way. Most wind turbines in use today are conventional wind
mills with three airfoil shaped blades arraigned around a horizontal axis. These turbines must be
turned to face into the wind and in general require significant air velocities to operate. Another style of
turbine is one where the blades are positioned vertically or transverse to the axis of rotation. These
turbines will always rotate in the same direction regardless of the fluid flow. Due to the independence
from the direction of the fluid flow, these turbines have found applications in tidal and surface current
flows. To see how effective this sort of
turbine would be in air, a helical turbine based on the designs.

5. ABSTRACT:
The objective of the project is to design a wind turbine to recapture
wind energy from vehicles on the highway. Wind energy is
considered the fastest growing clean energy source however; it is
limited by variable natural wind. Highways can provide a required
considerable amount of wind to drive a turbine due to high vehicle
traffic. This energy is unused. Extensive research on wind patterns is
required to determine the average velocity of the wind created by
oncoming vehicles. The wind turbines will be placed on the medians
therefore, fluid flow from both sides of the highway will be
considered in the design. Using all of the collected data, existing
streetlights on the medians can be fitted with these wind turbines.
Additionally, since the wind source will fluctuate, a storage system for
the power generated will be designed to distribute and maintain a
constant source of power.
Ideally, the turbine can be used globally as an unlimited power
source for streetlights and other public amenities. The design of the
wind turbine must include storage of power and a system to
distribute the generated power effectively. Operational noise level
and space are other important design considerations. The design of
the other parts like Shaft, Flange, Bearings etc. is also same important.

6.  WHATISWINDTURBINE..?
It is all about to produce electricity which generates energy from the traffic of passing vehicles.
along with natural wind, moves the blades of the turbines and transforms it into electric energy.
In this way, they say, highways become “sources to generate renewable energy.” also has a panel
to capture the sun’s energy,
Generating electric energy through the movement of cars also has economic advantages. “The
fact that each street light, traffic light, sign or SOS point has its own generator on the motorway,
and also that this generator is activated and fed by the cars that drive by, eliminates a large part
of energy production cost, and reduces installation and maintenance costs and favors the
environment,

7.  HOWITWORKS
In addition, the environmental impact of these turbines is rather low. They don’t need a lot of space, because they
are installed in already-existing median strips. They produce hardly any noise, especially when compared to that
from traffic, and animals –especially birds– would not be in danger because the blades turn slowly. Finally, they
could even replace medium-voltage electric cables.
The air stirred by these passing vehicles, along with natural wind, moves the blades of the turbines and transforms
it into electric energy. In this way, they say, highways become “sources to generate renewable energy.” Wind
turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a
rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.

8. The generator in a wind turbine produces alternating current (AC) electricity.
Some turbines drive an AC/AC converter—which converts the AC to direct
current (DC) with a rectifier and then back to AC with an inverter—in order to
match the frequency and phase of the grid.

Turbine (Motor) is used
Depending on wind conditions, the blades turn at rates between 10 and 20
revolutions per minute. Considering the length of the blades with average wind
speeds of 13 to 15 mph, the tips are traveling at 120 mph. At maximum wind
speeds, the blade tips are spinning at an estimated 180 mph.

9.  HOWDOWINDTURBINESWORKIF THEREIS NO WIND?
If there is too little wind and the blades are moving too slowly, the wind
turbine no longer produces electricity. The turbine starts to create power at
what is known as the cut-in speed. Power output continues to grow as
the wind speed increases, but at a slower rate than the wind rate
it does trigger the power point.

10.  DESIGNANDCONCEPTOFWINDTURINE

12. CONT:
The turbine must be able to store energy for use when there is low traffic, bumper to bumper or stop and go traffic.
The design must be sustainable and environmentally friendly. The motivation for designing a highway wind
turbine is to contribute towards the global trend in wind energy production in a feasible way.
Flat blades are the oldest blade design and have been used for thousands of years on windmills, but this flat broad
shape is becoming less common than other types of blade design.
Principalsof windturbines:
Wind turbines operate on a simple principle: they capture the kinetic energy in the wind and convert it into
electricity. The wind direction determines the design of the turbine. Upwind turbines face into the wind while
downwind turbines face away from the wind.17-Jul-2019.

16. Someimportantpartsof turbine:
Generator:
In a turbine generator, a moving fluid—water, steam, combustion gases, or
air—pushes a series of blades mounted on a rotor shaft. The force of the fluid
on the blades spins/rotates the rotor shaft of a generator. The generator, in
turn, converts the mechanical (kinetic) energy of the rotor to electrical
energy.
Anemometer:
Anemometer is an instrument used to determine the speed of the airflow in
the atmosphere and in wind flow tunnels. It can check the total velocity
magnitude of fluids on a horizontal plane or in a specific direction. The
effect of fluid on mechanical equipment is also determined by
an anemometer.

17. Electric Break:
The primary braking system for most modern wind turbines is the aerodynamic braking system, which
essentially consists in turning the rotor blades about 90 degrees along their longitudinal axis (in the case of
a pitch controlled turbine or an active stall controlled turbine ), or in turning the rotor blade tips.
Gearbox:
A gearbox is often used in a wind turbine to increase the rotational speed from a low-speed main shaft to a
high-speed shaft connecting with an electrical generator. Gears in wind turbine gearbox are subjected to
severe cyclic loading due to variable wind loads that are stochastic in nature.
Nacelle:
The nacelle of a wind turbine houses the drive train and other tower-top components. It sits on top of a yaw
bearing that allows it to rotate as the wind direction changes. The nacelle must be accessible for
maintenance and repair work. Access is usually via a lift and ladders within the tower.

18. The shaft of the turbine consists of a single two foot length of steel
measuring 3/8ths of an inch in diameter. The use of steel over a lighter
metal such as aluminium was based on the availability of materials on
McMaster-Carr where I sourced many of the materials and parts I
needed to purchase. The steel rod that was purchased for the shaft had
a straightness tolerance of ±0.05 inches where none of the aluminium
rods had a tolerance given.
BladeDesign
Blade convert kinetic energy of air from fast moving vehicle into
rotational energy by the turbine shaft. The rotary motion of shaft is
convert into electric energy with the help of PMDC (Permanent
Magnet DC) motor and electricity store in battery. Wind energy
generated by moving vehicles may not be continuous as there may be
idle time with no vehicle traffic and the turbine may need to stop and
start frequently. Therefore, start by itself property is one of the
important parameter in case of highway wind turbines.

19. • Design of Spoke:- The spoke arm component, shown in Fig
4, has three arms extending from the central hub of the
part with extended sections at the end of the arms to attach
the turbine blades. The leading edges of the arms were also
rounded to reduce the drag of the arms. For material, ¼
inch polycarbonate was chosen and the parts were
machined using a CNC machine.
• Design of Blades:- The turbine blades are the most
important part of this design. They are 14 inches long and
follow a helical path with a 5 inch radius over a 60 degree
arc. The cross section is a standard NACA 0018 air foil
with a 1.5 inch chord. Since the air foil is symmetric along
the chord, the mean camber line follows the chord. The
helical path that the blade follows is drawn along the
midpoint of the camber line and the blade is set at a 0
degree angle of attack. The profile of the air foil is shown
in the fig.

20. • The blades were produced using a 3D printer that
built the blades up a layer at a time with ABS
plastic. Due to the size constraints of the printer,
the blades had to be cut in half and then
assembled. The assembly was done with a
combination of plastic cement and pins to
strengthen the joint. Additionally, the joint was
cut in a step shape to increase the surface area for
bonding. While the glue and pins created a strong
joint,

2. Design of a new method of generation of electricity using the wind energy generated by the
moving vehicles on the highways.
3. Development Stand-alone system for providing the power to the highways.
4. Provide Charging Port for Electric Cars .

24.  ADVANTAGES
1).It's a clean fuel source: Wind energy doesn't pollute the air like power plants that rely on combustion of fossil
fuels, such as coal or natural gas, which emit particulate matter, nitrogen oxides, and sulfur dioxide—causing
human health problems and economic damages. Wind turbines don't produce atmospheric emissions that cause
acid rain, smog, or greenhouse gases.
2).Wind is a domestic source of energy: The nation's wind supply is abundant and inexhaustible. Over the past 10
years, U.S. wind power capacity has grown 15% per year, and wind is now the largest source of renewable power in
the United States.
3).It's sustainable: Wind is actually a form of solar energy. Winds are caused by the heating of the atmosphere by
the sun, the rotation of the Earth, and the Earth's surface irregularities. For as long as the sun shines and the wind
blows, the energy produced can be harnessed to send power across the grid.
Wind turbines can be built on existing farms or ranches. This greatly benefits the economy in rural areas, where
most of the best wind sites are found. Farmers and ranchers can continue to work the land because the wind
turbines use only a fraction of the land. Wind power plant owners make rent payments to the farmer or rancher for
the use of the land, providing landowners with additional income.

25. CONCLUSION:
The wind energy generated by the moving vehicles on highways can be utilized to
generate electrical energy which can be stored in a battery and used for purposes
like street lighting, Electric Car charging etc. This design concept is meant to be
sustainable and environmentally friendly. If these types of turbines can be
installed on long high speed express highways like golden quadrilateral, a
considerable amount of electrical energy can be generated, which can solve the
issue of energy crisis to a large extend. Using the collected data, a wind turbine is
designed to be placed on the medians of the highway. Although one turbine may
not provide adequate power generation, a collective of turbines on a long strip of
highway has potential to generate a large amount of energy that can be used to
power streetlights, other public amenities or even generate profits by selling .
