This study explored the possibility of using a combination of spoiled Kamias, Banana, and Pineapple (KaBaPine) fruits as an alternative source of power. It aimed to make dry cell contraction with KaBaPine fruits as the electrolyte and to be able to generate a substantial amount of potential difference from it.
The combination of fruits was pretested and yielded the potential difference of about 0.80 Volts. Factors that may affect potential difference, acid and base and the rate of the fruit’s spoilage, were tested on the KaBaPine combination. The test results revealed that there was no significant difference between the voltage produced by pure KaBaPine and those produced by KaBaPine combined with basic or acidic solutions.
Using zinc containers of old size C dry cell the contraptions were constructed. The KaBaPine was placed inside as the new electrolyte. The copper wire was soldered to the base of the cap and was used to seal the cell to replace the carbon rod in common dry cells. The improvised KaBaPine cells were connected in series and were able to generate enough amount of voltage that could compete with the commercially available ones.
Making an SIP (Science Investigatory Project) is not like a “walk in the park”. It needs perseverance, determination and hard work. Although it requires money, the investigators were able to comply the needed materials for our mind blowing experiments.
Because of the infinite support, trust and devotion, people who truthfully deserve worth and appreciation, this price of work was made possible. And now, we the researchers would like to thank and acknowledge the people who served as cornerstones and gave us a strong foundation to finish our project with finesse.
To our parents: Mr. and Mrs. Simplicio T. Balleza Jr, Mr. and Mrs. Romeo M. Gania, Mrs. Vernicita A. Lopez, Mr. and Mrs. Ernesto Matulac, Mr. and Mrs. Daniel Mercado Sr., Mr. and Mrs. Ernie Monterde, Mr. and Mrs Joseph Palmes, Mr. and Mrs. Rey Sayon and Mr. and Mrs. Benigno Toribio for showing us their never ending support. To our teachers, Mr. Fortunato Bacus, Mr. Jonathan dela Peña, Mrs. Emilita Sunga, Mr. Dionisio Dionaldo, Mr. Elmer Espia, Mr. Darwin Locsin, Mr. Ismael Fantilanan, Mrs. Maylene S. Orencio, Mrs. Julieta Javier for the advices and considerations that they have given to us and to Ms. Girlie Cabale and Mr. Julie Gentison for guiding us in working our project.
And the most important is our Almighty God for the countless Blessings and Guidance, for the knowledge and wisdom that we may understand our project and granting.
A. Background of the Study
Since the beginning of year 1992 the country has been experiencing daily brownouts as a result of power shortages especially, nowadays that we are in the middle of global crisis. One logical solution to this major problem is to look for non-conventional sources of energy such as dry cells or batteries which provide a source of power when electricity is not available.
A battery produces power through chemical reactions that produce electrons which is called electrochemical reactions. A simple example of this is seen in the classic children experiment where electricity is generated from a lemon. By suspending two types of metal in an acidic...
