ABSTRACT
In the present scenario of our environment wastage or
misuse of energy, destruction of forest, pollution etc are
some of the serious issues. People need comfort and they
are busy in buying comfort in terms of money. Rich and
middle class people are busy in arranging all the amenities
in their homes. One such example is an Electric Geyser.
But, very few people think about our original home to live
in: The Earth.
An electric geyser is a commodity of modern society
which runs in electric current. Use of such electric geysers
emits CO2 gas besides consumption of electric current. In
winter, many of us use hot water for taking bath and we
use firewood for this purpose. All these activity actually
lead to serious environmental issues.
Since a hot bath is essential in winter, it is necessary
to develop some alternative means to obtain hot water for
taking bath or for other domestic and industrial uses,
which is economic and above all eco-friendly. In this regard
the concept of Solar Geyser is an important one.
In our project work, we have made a model of a Solar
Geyser with a metallic container (tin) and covered it with
thermocol on its outer sides. A thick layer of black paint is
applied on the inner surfaces of the tin container which
makes the container capable of preventing heat loss up to
certain extent from inside. The upper open surface of the
container is covered with a glass which would allow the
sunlight to enter the container.

We kept the container in the sun by filling it with
water and used to record the temperature of water inside
the container in every half an hour with the help of a
laboratory thermometer. We also kept an ordinary
container of equal size and filled with equal volume of
water (as in the experimental container) and took the
temperature reading of the water at the same time. We
continued this for 7 days from 16-09-2009 to 22-09-2009
from 8:00 am to 12:00 noon.
After analyzing the data, we found that the water in
the model geyser (experimental container) was warmer than
the water in the ordinary container. This indicated that
water can be made warmer by using sun’s heat and thus
the concept of a solar geyser in our homes or in office can
be a good alternative to electric geysers.
Since a solar geyser is eco-friendly, economic and easy
to use, we suggested our parents and neighbors to make
necessary arrangements to construct such solar geysers for
hot water supply. We discussed the importance of such
solar geysers with our classmates and teachers as well.
Use of such solar geysers can definitely save energy
and also will protect our mother nature from getting
polluted by the emission of harmful CO2 gas.

INTRODUCTION
In relation to the theme of NCSC: 2009 “Earth: Our Home:
Explore, Share and Care” we have selected a subject for our
project with the title: ASPECTS OF SOLAR GEYSER IN SAVING
ENERGY ANDNATURE.
In the present scenario of our environment wastage or
misuse of energy, destruction of forest, pollution etc are
some of the serious issues. People need comfort and they
are busy in buying comfort in terms of money. Rich and
middle class people are busy in arranging all the amenities
in their homes. One such example is an Electric Geyser.
But, very few people think about our original home to live
in: The Earth.
An electric geyser is a commodity of modern society
which runs in electric current. Use of such electric geysers
emits CO2 gas besides consumption of electric current. In
winter, many of us use hot water for taking bath and we
use firewood for this purpose. All these activity actually
lead to serious environmental issues.
Since a hot bath is essential in winter, it is necessary
to develop some alternative means to obtain hot water for
taking bath or for other domestic and industrial uses,
which is economic and above all eco-friendly. In this regard
the concept of Solar Geyser is an important one.

NEED STATEMENT
An electric geyser is a device which is used to get hot
water in our bathrooms, hospitals, hotels, office etc. It
consumes electric current and very expansive too. In our
state, Assam there has been a huge shortage of electric
power supply and therefore, using such electrical devise
adds more problems in this field. An electric geyser also
emits harmful carbon dioxide gas which adversely affects
our environment in rising the global temperature.
Some people, who don’t use such geysers, use firewood
for obtaining hot water. This is another issue as per as
environmental pollution is concerned. Burning of carbon
produces harmful carbon dioxide gas and to get the supply
of firewood people cut down trees in large scale.
Since, a hot water bath is essential in winter, it is
necessary to develop some alternative means of obtaining
hot water which is eco-friendly, non-conventional and
cheap. Keeping this urge in our mind, we have selected this
project for making a model of solar geyser and to test its
efficiency in getting the supply of hot water without using
electricity.

WORK PLAN
After selecting the subject for our project, we made a
model of solar geyser with a metallic container and covered
it with thermocol on its outer sides. A thick layer of black
paint is applied on the inner surfaces of the tin container
which makes the container capable of preventing heat loss
up to certain extent from inside. The upper open surface of
the container is covered with a glass which would allow the
sunlight to enter the container.
We kept the container in the sun by filling it with
water and used to record the temperature of water inside
the container in every half an hour with the help of a
laboratory thermometer. We also kept an ordinary
container of equal size and filled with equal volume of
water (as in the experimental container) and took the
temperature reading of the water at the same time. We
continued this for 7 days from 16-09-2009 to 22-09-2009
from 8:00 am to 12:00 noon.
We then decided to compare the rise of temperature of
water in the model geyser with the temperature of water in
the ordinary container to find out the efficiency of our
model of solar geyser. We also planned to carry out our
experiments for a period of 7 days from 8:00 am to 12:00
noon.

METHODOLOGY
At first we made a rectangular metallic container ready
and cut out its one surface. All the other five surfaces were
painted with clack colour from inside to prevent heat loss
from inside the container. Further, the outer surfaces were
covered with an insulator, thermocol to prevent conduction
of heat. We collected a piece of transparent glass to cover
the upper open surface of the container. This glass piece
will allow the heat and light of the sun to enter the
container and will prevent the heat to escape.
We filled the model of the geyser (experimental
container) and an ordinary container separately with cold
water of equal volume and kept the two containers in the
open sunlight everyday from 8:00 am to 12:00 noon. We
did it from 16th September, 2009 to 22nd September, 2009
regularly. We recorded the temperature of water in both the
containers at an interval of every half an hour.
During our project, on 16th, 17th and 18th September,
2009 the weather was cloudy. So, we didn’t get an effective
result. By the evening of 16th September that has
compelled us to think about arranging a solar heat
collector and accordingly we put a mirror near the model of
the solar geyser so that the mirror could reflect the light
and heat into the container even during a gloomy weather.
After arranging this heat collector, we started getting
comparatively better result on 17th and 18th September.
After collecting the data for 7 consecutive days, we
compared the temperature rise of the water in the two
containers to detect the efficiency of the model geyser.

RESULT
The data of the temperature recorded of the water in
both the model solar geyser and ordinary container have
been placed in a chart from 16th September to 22nd
September, 2009. This data chart gives us a clear idea that
the water in the model solar geyser becomes hotter than
the water in the ordinary container in same time interval.
Of course, the rise of temperature is rapid in the sunny
days than the cloudy days or partially cloudy days.
The recorded data of the temperature of water is given
below:
FIG 3: TEMPERATURE OF WATER

DATA ANALYSIS
From the recorded data we have to come to know that in a
cloudy day the temperature rise is not up to the mark. On 16th
September, 2009 at 8:00 am the initial temperature of the water
was 310 C in both the containers. But at 12:00 noon the
temperature recorded was 320 C in the ordinary container and
33.60 C in the model solar geyser. Thus there was a difference of
only 1.60 C on the cloudy day of 16th September, 2009.
!7th and 18th September, 2009 were partly cloudy days and we
arranged a solar heat collector with our model solar geyser. That
resulted in a much rise of temperature of water. On 17th September
the difference was 3.50 C and on 18th September it was a difference
of 4.10 C.
19th to 22nd September, the days were sunny and we observed
remarkable difference of temperature in those days.
Date of
observation
Temp difference in
ordinary container
Temp difference in the
model solar geyser
16-09-2009 10 C 1.60 C
17-09-2009 1.50 C 3.50 C
18-09-2009 1.80 C 4.10 C
19-09-2009 4.60 C 8.30 C
20-09-2009 5.60 C 9.40 C
21-09-2009 6.50 C 10.30 C
22-09-2009 3.50 C 10.30 C
These data clearly show that in the solar geyser during the 4
hours of observation the 20 liters of water becomes hotter than in
the ordinary container and the average temperature difference was
found to be about 100 C. this indicates that such solar geysers can
be used in our homes during winter seasons.

SOLUTION TO THE PROBLEM
During our project work we explained our findings to
our parents and neighbours besides informing them about
the necessity of such solar geysers. We also informed our
classmates and teachers about this.
During the discussion we let them know about the ill
effects of using electric geysers. We tried to make them
understand that we have this earth not from our ancestors,
but taken it for lend from the coming generations and we
will have to leave this mother earth for our next
generations to come.
If we really want our future generations to enjoy a
better living earth for them, then it is our time to get up
with this alarm bell and start thinking and acting from
today for a better earth of tomorrow.

CONCLUSION
In order to save our earth from pollution, we must stop
burning the conventional or traditional fuel and this could
only be possible if we can get some eco-friendly alternative
source of energy.
In winter as we warm water by using firewood or by
using an electric geyser, we actually disturb the
environment by:
a) Emitting harmful carbon dioxide
b) Cutting down the trees for firewood and
c) Using electrical energy.
But we can save our environment or control the
pollution besides moving one step ahead to conserve our
forest recourses by using this proposed solar geyser. Such
solar geysers would be effective even in schools, hospitals,
offices, hotels and laboratories etc. We can make such
solar geysers of our own at a very low cost.
If we really want to Explore, Share and Care of our
Earth, we must come forward to use solar geysers instead
of an electric geyser.
