Abstract :
The negative effects of non-renewable fossil fuels
have forced scientists to draw attention to clean energy
sources which are both environmentally more suitable and
renewable. By using the wind energy, power may be
produced. The project entitled “Energy Produced by using
the Wind Energy” is aimed to produce power with
renewable source of energy like wind. In this project by
using a small fan blade, electric power is produced by
utilizing the drag force of the wind in a moving vehicle. This
project aims to design a model for using wind energy to
generate electricity which in turn may be used to run
electrical utilities directly or through a storage battery
Keywords – Drag, Wind, Energy

Introduction :
The negative effects of fossil fuels which are
non-renewable have forced the scientists to draw attention to
clean energy sources that are both environmentally more
suitable and renewable. One of these sources is wind energy.
Global wind energy market among other renewable sources
has been experiencing a rapid growth especially during the
last two decades. Wind is a fuel-free, inexhaustible energy
source and does not cause pollution in electricity production.
Today, wind energy is widely used to produce electricity in
many countries in America, Asia and especially Europe.

• At first glance it is not evident why a non
standard solution will be best for a low power
wind turbine set. Nevertheless, car alternators are
very rugged and both they and their spare parts
are widely available in third world
• Countries where other electric equipment is hard
to find, or in any case, hard to repair. Hence the
use of a car alternator as the generator in a wind
turbine set for use in isolated third world
locations is interesting, providing the other
alternator characteristics are adequate for the
application.

Objectives:
• My objective is to discover wind energy
obtained from small wind turbines attached
to an electric car can provide enough power
to charge the battery of the car while
driving.

Car Alternators as Wind Turbine Generators :
• The use of a vehicle alternator as the wind turbine
generator offers the following advantages:
• 1) They are commonly used in widespread applications
such as cars, trucks, buses tractors and other farm and
industrial vehicles.
• 2) Great mechanical strength.
• 3) Spare parts such as windings, rectifier bridges, voltage
regulators, bearings, can easily be found in auto part
dealers shops, in almost all towns in the world.
Also car maintenance workshops, with mechanics able to
perform basic maintenance work in this equipment can be
found even in otherwise very isolated and backward
locations.

• 4) Wide operating speed range, from 400 RPM to 8000
RPM, and good current generating capability, reaching
320 A in modern units.
• 5) Available in standard output voltages of: 12, 24, 32 or
48 V.
• 6) A range of matching heavy duty batteries are also
widely available, designed to be directly charged from the
car alternator.
• 7) A range of matching (and rugged) integrated output
voltage regulators are available in the market.
• 8) Some special models offer three phase AC outputs.
• 9) Low unit and spare parts cost.
• 10) Easy maintenance.
• 11) Tolerance to wide operating temperature changes
without significant performance degradation.

Working principle of wind turbine :
• The unit producing the power from wind is
known as a wind turbine. Wind turbine (Rotor)
mounted on a main shaft collects the kinetic
energy from wind.
• With the help of gearbox the speed is raised on
the other hand it is fed to the electric generator
shaft.
• The electric generator converts this mechanical
energy into electrical energy. Our project working
principle is same as like that, it is water lifted by
pump which is operated by wind turbine.

Conclusion:
• In the field of automobile sector, this kind of
experiment is new. By implementing this
system on an automobile, the fuel efficiency
of an automobile increases without
hampering environment. Moreover, the cost
of the project is low and could be recovered
within three years. In the first trial the
expected results were not satisfactory.
However, in second trial the output of 50W at
the speed of about 100 kmph was achieved

• With this much output, any one of the
electrical systems in the vehicle could be
operated with the help of second
combinations of fans. Again it is observed
that when vehicle is accelerated the output
increases and vice-versa.
