Gravity Sourced Pedaled Personalight (GraSPP)

Abstract

INTRODUCTION

Appropriate understanding in searching for alternative energysource should be regarded as an essential research in the world. Renewable energy are energies which came from natural sources like sunlight, water, and etc., and numerous studies have already claimed useful alternative energy sources to help serve communities. But there are billions of people who have limited access in electricity which made the researchers explore this innovation, an accessible source, which is gravity in generating power.

METHODS

The project is designed as a pedal and gravity-powered light wherein the pedal will pull the weight up from a high altitude that would drive a handcrafted gear to a main wheel, where the rope is attached, so the gravitational energy of the weight will be converted to electrical energy. When the weight falls from a high altitude, the potential energy of it will be converted to kinetic, thus converting it to electricity that would came from a generator, and it produces energy that powers an LED light and a charging port.

RESULTS

The wholly measures and procedures were shown in the prototype. The force exerted on the pulley system, duration, velocity, and the voltage produced by the generator was strictly observed. Individual observation for each condition was conducted, expected number of trials were determined depending upon the result of the proposed designs: when weight is constant, when height is constant, when both parties are not constant.

DISCUSSIONS

Researching alternative energy source has become an essential for people, and to the researchers. Today, they make use of renewable energy such as gravity which this study explored. The GraSPP project, with its fundamental concepts provided solution to some of the complications the researchers might experience. This project helped by using the weight's potential energy to be converted to kinetic energy that was would react to a certain force (gravity) once the weight starts falling very slowly. This kinetic energy produced electricity that came from a generator that would eventually produce light energy from the LED light.
