Here, is the first presentation on slideshare on how to make a working model of a hydroelectric and solar power plant and present your model through the presentation. It will provide you enough information on the model when you are going to present it from school. It will prove to be very helpful for your science projects.

Hydroelectric And Solar Power Plant

2. You probably have listenedthethermal
powerplant.It uses coal toproduce
electricity.Hydroelectric power plantalso
works in a similarwaybut itdoesnot use
coal, onthe otherhandit usesthepotential
energyofwaterwhich isbetterthan
producing electricityin thermalpower
plants.Damsare thestructurewhich helps
inits production.
What Is A Hydroelectric Power
Plant?
SolarPanelconverts solarenergy to
electricalenergy.

3. MATERIAL REQUIRED
Front Wheel Of A
Tricycle With Shaft
Plastic cups
DC Motor
Small Gearing System
Chain. Front And Rear
Derailleur of Bicycle
Other small things like LED’s, wires, tape etc.
Solar Panel

4. Making Of The Turbine
ORIGINAL TURBINES
MODEL TURBINE
(Small Scale)
To make the turbine of the model, paste plastic cups around the front wheel of the
tricycle containing the shaftso that it can be fixed on a stand.

5. ENERGY CREATION
In the model, we can create energy by setting a bottle at a position
vertical above the turbine. When water is poured through the bottle on
the turbine cups clamped on a stand made of wood, turbine starts
rotating with a speed and this can be used to rotate the dynamo. Only
mechanical energy is produced.
Energy can be directly produced by the use of solar panel in the model
which directly converts solar energy to electrical energy.

6. DYNAMO

DC MOTOR

DC MOTOR
(with gears vertical view)
 I have used a small scale of generator to convert mechanical energy
into electrical energy which is known as the DYNAMO. This is the
main part.
 When the turbine rotates, it also rotates a chain which thereafter
rotates the gearing system of motor. Gearing system is used to
increase the number of revolutions per second of the motor.

7. SOLAR PANEL
Solar panel is a device
consisting of solar cells.
These cells convert the
solar energy falling on
them to electrical energy.
I have used the solar panel to increase the output of my
model. Hydroelectric power plant and solar panel together
can easily produce an electricity enough to charge a mobile.
It does not require any other thing to produce electricity.
Electricity produced by it is combined to the electricity
produced by hydro project to increase voltage.

9. WORKING ( R e a l D a m )
In it water is made to fall from a height on to the blades of a turbine, and the blades start
rotating. This rotating turbine transfers energy from a shaft to a generator which in turns
rotates and produces electricity which can be used for a number of purposes.

10. WORKING ( M O D E L )

11. Why Should We Prefer These Projects
Over Others?
The production of energy from hydroelectric, solar, tidal power plants do not
cause any pollution whereas thermal, nuclear power plants causespollution and
environmental problems due to burning of fossil fuels and nuclear waste.
These are renewable resources, so ones set up, they will work indefinitely by
proper maintenance whereas most of the current electricity project are of non
renewable resources and will be of no use after exhaustionof fossil fuels or
nuclear material etc.
