Gravity Light: Using Gravity for Producing Light—Cost Report

Abstract

In this modern world, we all have the pleasure of using electricity and other amenities, but there are places where there is no electricity and so no light, where the people’s day starts when sun rises and ends when the sun sets, and so they do not perform any activity after sunset like the medieval people. Now the answer to this problem rises, why don’ they use solar and wind energy; well, the problem is that they both are not available at every corner of the world, especially in the hilly regions and some remote villages where the sun is hardly visible, and so to solve this problem, we need a force or energy which is available everywhere on the surface of earth, and that is gravity. The gravitational force is available equally and constantly without any hindrance on every corner. This mechanism is new, but some regions use it; this mechanism is used by entrepreneurs as a product. This mechanism is called gravity light, which works on the concept of bicycle dynamo electricity generation. The only difference is that here we will be using gravitational force instead of pedaling. The overall setup can be made indoors by any layman having a little understanding of bicycle, and it can be operated just by hanging some weight to gear train which in turn rotates the wheel and which rotates the motor which generates current producing light. It is a very low-cost setup and the cost can be recovered in 3–4 months as compared to the cost of kerosene lamp or using wood to burn, which will cause harm to health.
