The researchers named their project as “Eco Clock.” They chose to investigate on this project because they are aiming to promote the use the natural resources as a source of electricity. They were able to look for other possible substitutes for dry cell batteries. The use of the fruits in producing current is a revelation that fruits are not only nutritious foods that give vitamins and minerals to keep the body healthy but also a very important tool that help people live comfortably.


The investigatory project is entitled Eco Clock. The group aims to help people from rural places, most likely the ones living in the provinces to benefit from their research. The purpose of the project is to discover substitutes for dry cell batteries because although it is very useful, it has a disadvantage which is that it is flammable and hard to dispose. They found out that some basic material at home can be a great substitute for a dry cell. It shows that fruits and vegetables are not only for giving nutrients but helps in making an electronic device work which is supported by the current. Fruits and vegetables also have the some disadvantages but we can easily replace rotten fruits and vegetables with a new one for there is an abundance of fruits and vegetables around us. The energy for the battery comes from the chemical change in the zinc when exposed to the acid and potato. The zinc is oxidized inside the lemon, exchanging some of its electrons with the acid in order to reach a lower energy state and the energy released serves as the power. The reason is that there is no such thing as electricity found in fruits, but perhaps, the chemical properties stored in some...
