DRAWBACK ASSOCIATED WITH KNOWN ART
Millions of people in the world are in the need of electrical power for their better
living. Different power generation/production methods or systems are existing in
the world. Wind Energy -A Renewable Energy- is one of the main sources. Wind
Energy has been used since 3000 BC, in the world for sailing and other purposes.
Wind turbines are erected in different countries in various places by using larger
area of land with heavy structures to produce electricity.
Many kinds of electricity generation systems are in the world needed larger
infrastructures and sufficient capital investment.
Wind energy based electrical power production in the mobile train is a unique method
and a novel technological step in the world. It needs no extra infrastructure and huge
capital. It is produced up on readily available mobile structure. Wind turbines are erected
upon the rooftop of railway coach bodies. So, there is no need of large area of land or
any infrastructures.
The cost of generation per unit is also an important factor in the world. Huge capital and
heavy infrastructures with vast area of land and other needed sources are adding the
expenses of electricity production.

FUNCTION OF THE NOVEL PROJECT
Ref: - Figure. 1
The exploded view of the Wind Turbine mounted upon the rooftop of the running
railway train coach body (12) with Rotor, blades and necessary parts, facing open
air flow. It is erected on the mounting b&e (I), which is especially fitted upon the
coach body for this purpose.
Railway train coach bodies are available in many states/countries in the world; it
has been build for passengers and other transportation purposes in general. It is
ready made and easily available structure; which can also be utilized for the
production of energy - electrical power for mankind,human society in the world.
The coach body has sufficient surface to erectlmount the Wind Turbine on its
rooftop.
The Mounting Base (1) is fixed both sides on the rooftop of the railway coach to
erect the Wind Turbine and all its accessories with required parts. The Mounting
Base holds all these, in all running conditions of the railway train and its coach.
The Wind Turbine also erected on both sides of rooftop of the coach. At least two
Wind Turbines - one on each side - can be fitted on a coach to operate.
Ref: - Figure. 2
View of main parts of wind turbine and its attachments.
The RotorIHub (2) of the Wind Turbine is fitted vertically in the mounting base
and spins in the same manner according to the kinetic power applied on the
blades (3). When the train and coach takes its running movement, natural air flow
added with speedy motion based on train's speed the kinetic energy of wind and
its force called lift on the blades, causing the rotor to rotate.
The blades are rotating in horizontal direction. It is designed just cup like curved
shape so as to keep its rotation in a same direction, even in the to-fro movement
of the coach changes its direction. The design of the blades can be changed as per
requirement or as decided.
The Turbine Shaft - Low Speed Shaft-(4) is to spin according to Rotor. It is a
main shaft. Turbine Shaft is connected 10 the Gear Box (5). When Rotor spins,
the Turbine Shaft also rotates. It is vertically fitted with rotor.
The Gear Box (5) is operated by the rotation of Turbine Shaft. The Gear Box is
helpful to increase the speed or as required speed or as designed; according to
this, the gears are fitted and arranged in side of the box. The gearbox steps up the
revolutions from the low-speed shaft and the Rotor, to the high speed shaft of the
generator.
The Generator Shaft (6) is also fitted in the vertical position. It can be fitted or
arranged to fix in horizontal manner, if needed or designed so; the gear box and
the gears are to be fixed according to this. It is operated and rotated by the Gear
Box as per required or decided speed. The rotation of Generator Shaft helps to
produce electricity by the Generator (7). Generator is working as per existing law
and rules of Physics.
Naturally available Solar system a d S d s beaming rays heat the Earth, but not
evenly. Many attributes of the Earth - such as its atmosphere, topography, bodies
of water, rotation and other factors - contribute to uneven heat distributions,
which create air movement, or wind. Wind turbines are used to generate
electricity from the kinetic power of the wind.
On this basis, when the Railway train coach moves in the open air; the wind force
acts with more kinetic power according to the speed of the train. Kinetic power of
wind becomes many folds due the running speed of the train coaches and its force
called lift on the blades, causing the rotor to rotate. The blades are mounted to the
central hub at a pitch, or angle. Blade rotation causes gears to spin inside a
transmission system contained within the turbine.
The spinning rotor then turns the low speed rotor shaft which is connected to the
gear box. The gear box rotates the generator shaft - high speed shaft - and
generator produces electricity. Thus, generator then converts the spinning gear
motion into electricity.

(8). The novel and inventive method of producing electricity as claimed in the
claim (I), wherein the invention of renewable energy method of producing

Wind energy is kinetic energy of an air motion. Total wind energy flowing
through an imaginary area 'A' during the time t is:
Where p is the density of air: v is wind speed: Avt is the volume of air passing
through A (which is considered perpendicular to the direction of the wind): Avtp
is therefore the mass m passing per unit time. Note that ;1pv 2is t he kinetic energy
-
of the moving air per unit volume.
Power is energy per unit time, so the wind power incident on A (e.g. equal to the
rotor area of a wind turbine) is:
Wind power in open air stream is thus proportional to the third power of the
wind speed; the available power increases 'eight fold' when the wind speed
doubles.
Railway train and its coaches are under high speed during the travel as per
engine speed; thus, the wind speed also in many folds. It helps naturally to
increase the speed of wind in many-folds. The high speed of wind and its kinetic
energy converts mechanical energy to produce more and more electrical power.

electricity by wind power from running railway trains is, economic by installing
wind turbines on readily and easily available rooftop of railway coaches. At least
two wind turbines - one in the front side (engine faced side) of right half part and
another in the backside (guard van side faced) left half part of a coach - are
possible to install on each coach means, 'a train contains five to twenty coaches
can carry minimum ten to forty wind turbines to produce sufficient
electrical power is more beneficial and economical.
