Abstract
Conserving energy is definitely a necessity. It would prevent running out of resources and make it last longer to help the environment. One help in conserving energy is by using generators. Electric generator is a device that converts mechanical energy to electrical energy. In order to make it cost less or cost free, variations of sources of mechanical energy for it is designed and innovated. A gear can be used as a driver for a generator, and a series of gears or a gear-train will provide gear ratios for an increase in the output mechanical work. With a help of a spiral torsion spring of metal ribbon used as a power source in mechanical watches, some clocks, and other clockwork mechanisms or what is called a Mainspring, winding it with a key will store energy in it by twisting the spiral tighter and when it unwinds, the force of the mainspring will then turn the connected gear on it meshed with the other gear in the gear train. By using the mainspring and proper application of gear ratios, continuous work will be produced in a specific amount of time as an input source of mechanical energy for the generator. The purpose of this study is to determine the capability of themainspring-powered prototype in lighting LED. The design is to make a little effort on winding the mainspring which will result in a long time of electric current generation. This study will serve as a theoretical model for future studies to innovate a device that will generate electricity without an AC/DC input. Future researchers will benefit from this study, and it willprovide them the data needed to compare their study during their respective time and usability.

CHAPTER 1
Introduction

1.1 Background of the Study
There are several major problems that our country is facing nowadays, including power shortages. A power outage is a short- or long-term loss of the electric power to an area. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, or the overloading of electricity mains. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, mines, and the like will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost.

This is why the researchers intended to know if any element could be used for generating electric current, such as mainspring, a spiral torsion spring of metal ribbon used as a power source in mechanical watches, some clocks, and other clockwork mechanisms. Winding it, by turning a knob or key, stores energy in the mainspring by twisting the spiral tighter. The force of the mainspring then turns the gears as it unwinds, until the next winding is needed and a gear train that is formed by mounting gears on a frame so that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next.

1.2 Statement of the Problem
The proponents aim to present the general problem and specific problem. 1.2.1 General Problem:
The purpose of the study is to observe the capability of the portable devicein energy conversion, and to determine if the mainspring can be a source for electric current generation. 1.2.2 Specific Objectives:

This study aims to answer the following:
Can this portable deviceproduce electricity to light an LED bulb? 1.3 Hypothesis
The energy produced by the mainspring is mechanical energy. From the winding of the spring from human power (chemical energy) it would be converted to mechanical energy when released of tension. Turbines in power plants uses mechanical energy before the generator could convert this...
