2. 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. 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. For this project we
are looking for “Vertical Axis Wind Turbine”. The price of turbines is increasing
in accordance the cost of designing the turbine, calculated in energy savings
must be recovered in a reasonable time period. Each vehicle on the highway
offers an intermittent and uncontrolled source of wind power. 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.
3. Most people may be familiar with the horizontal
axis wind turbines that dominate wind farms.
These turbines have much of the major
components at the top of the tower. The blades
must be configured in the direction of the wind.
They also have gearboxes which amplify the
angular velocity of the rotating blades. The
blades must be very rigid and offset a certain
distance to avoid collision with the tower. Three-
blade designs are generally used for commercial
production of power with the assistance of
computers to orient the blades into the wind.

5. Savonius turbines are one of the simplest turbines. Aerodynamically, they are drag-type
devices, consisting of two or three scoops. Looking down on the rotor from above, a
two-scoop machine would look like an "S" shape in cross section. Because of the
curvature, the scoops experience less drag when moving against the wind than when
moving with the wind. The differential drag causes the Savonius turbine to spin.
Because they are drag-type devices, Savonius turbines extract much less of the wind's
power than other similarly-sized lift-type turbines. Much of the swept area of a Savonius
rotor may be near the ground, if it has a small mount without an extended post, making
the overall energy extraction less effective due to the lower wind speeds found at lower
heights.
7. This design methodology is to increase the efficiency of the windmill at first the designing
steps starts with the design of windmill blades. Because this blades will mainly affects the
overall efficiency of the windmill. For a particular application the wind mill blade should
be in required size. Before this getting knowledge about the aerodynamic style of
windmill blade in order to get the full efficiency is very much important.
8. India has vast supply of renewable energy resources.
India is currently suffering from major shortage for electricity.
India should become one of the leading power produce in the
world, but the current technologies are not sufficient to
achieve our goal.
To overcome the above problem we need to implement the
new technologies in production of energy. Smart wind power
is the conversion of wind energy into useful from of energy
such as electric by using wind turbine in the middle of either
or sides of the highway to generate electricity.
