ACKNOWLEDGEMENT

The researchers wish to extend their sincerest appreciation to the following people who helped

make this research. They are the people who helped and contributed much for the success of this endeavor.

To the Almighty God, for his gift of wisdom and understanding to us and for answering our prayers in times of our need. To our investigatory project adviser, Mr. Clifton C. Duavis for teaching us the fundamental of research and investigatory writing and for showing a great deal of patience through at times we tend to be naughty. To our Parents and Family members, for the unending love and support that they gave to Us. To the observer/respondents, for their integrity and cooperation. And lastly to the, St. Peter’s College-Basic Education Department for providing us with good environment and facilities’ to complete this project, and lastly, to all those who were part of this work, we would like to extend our deepest thanks to everyone.

DEDICATION This study is lovingly dedicated to our Almighty God, for the knowledge, guidance and protection that he had given to us

To our respective parents who have been our constant source of inspiration. They have given us the drive and discipline to tackle any task with enthusiasm and determination. When we were doing this project,

To our brothers, sister, relatives and friends who inspired us to make this study a successful one, without their love and support this project would not have been made possibe.

And to the future research study and many find vital information for this endeavor.

Chapter I THE PROBLEM AND ITS SCOPE Introduction The Sun is stable source of energy that is transferred to the Earth as light energey and heat energy. Light Energy is a Radiant Energy is that electromagnetic waves while heat energy is a form of energy that is transferred by a difference in temperature. We can use this energy by the use of the solar energy. Potato (Solanum tuberosum) is an important food crop of the world. It is used as vegetable, stock feed and in industries for manufacturing starch, alcoholic beverages and other processed products.

Potato is a highly nutritious food. It provides carbohydrates, proteins, minerals, Vitamin C, number of B group vitamins and high quality dietary fiber Potatoes yield about 97 Kilo calories per 100 gm fresh weight, which is much less than cereals. The net protein utilization or biological value of potato protein (about 71% that of whole egg), is better than that of wheat (53%), maize (54%), peas (48%), beans (46%) and is comparable to cow’s milk (75%).

Potatoes offer more than just a valuable source of nutrition, now they can also power your lights and computers, say Israeli researchers. The scientists from Hebrew University of Jerusalem (HUJ) have discovered that potatoes can be used as organic batteries, providing a cheap, immediate and easy to use source of green power to parts of the world that currently lack electrical infrastructure. It’s a development that could improve the quality of life of 32 percent of the developing non-OECD populations – some 1.8 billion people (http://www.israel21c.org/environment/where-theres-a-potato-there-could-be-light Retrieved: October 29, 2014)

Statement of the Problem This study developed that a potato can light a bulb that will help us to conserve energy.

Specifically the researchers seek an answer to the following:

•

What is a potato?

•

What are the use of potato?

•

How does a potato produce electricity?

•

What are the advantages of a potato out of the other electrical system?

Objectives of the study There are many food crops, including potatoes, which are wasted every day. Most of the crops are discarded or thrown away. Potatoes are often discarded, being the fourth largest food crop with only so many to buy them.

One of the researchers’ goals was to lessen the

wasted food crops by finding other uses for them. The researchers also found that this investigatory project is an introduction to the potential of potatoes to generate an ample amount of electricity fit for rural areas. According to the research of the Hebrew University of Jerusalem, a slice of potato can generate 20 hours of light, and several slices of potatoes could power a simple medical equipment or even a low-power computer.
