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. So review has been made in order to make this project successful.

6. WHAT IS WIND TURBINE..? 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. How it works 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. 24V 400W Permanent Magnet Electric Motor 3-Phase Synchronous Alternator NE-400 Permanent Magnet Electric Motor Generator DIY for Wind 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. How do wind turbines work if there is 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. DESIGN AND CONCEPT OFWIND TURINE

11. 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 . Principals of wind turbines: 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.

12. COMPONENTS AND MATERIALS The turbine blades are made of durable lightweight material. A mold is created and used to produce all 3 blades. The shaft is made from PVC pipe. The generator, alternator, batteries and other components are bought. 6 PARTS OF WIND TURBINE: Wind turbine components : Foundation Connection to the electric grid Tower Access ladder Wind orientation control (Yaw control) Nacelle

13. 6 PARTS OF WIND TURBINE Nacelle Generator Anemometer Electric or Mechanical Brake Gearbox Rotor blade Blade pitch control Rotor hub MATERIALS USED IN : wind turbines are predominantly made of steel (71-79% of total turbine mass) Fiberglass resin or plastic (11-16%) iron or cast iron (5- 17%) copper (1%) and aluminum (0-2%).

14. Some important parts of 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.

15. 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.

16. 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. Blade Design 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.

17. 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.

18. 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,

19. Important terms: Impact Wind Energy Anemometer Impact pressure thrust depends on different factors as follows:- The intensity/frequency of the vehicles traffic. The size of the automobiles. The speed of the automobiles. Distance between the harnessing system &vehicles. Angle of Impact. Velocity of natural wind.

20. Applications: the peak efficiency of a cross-flow turbine is some times than a kaplon, fancies or Pelton turbine it has a low price, and good regulation. cross-flow turbines are mostly used in mini and micro hydropower units. its efficiency decreases as flow decreases. Francis type units cover a head range from 40 to 600m(130 to 2,000ft). there exist in multi to Pelton wheels mounted on vertical oil pad bearing in hydroelectric power. industrial applications including, road signage, remote telemetry, mobile base stations and for houses, schools and farms generator acting as a large electrical motor during periods of low power demand

21. Objective of Project: In corporation of more renewable energy to the power system. Design of a new method of generation of electricity using the wind energy generated by the moving vehicles on the highways. Development Stand-alone system for providing the power to the highways. Provide Charging Port for Electric Cars .

22. 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.

23. 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 .
