Gravity Light

Project Overview

The Gravity Light project was an innovative approach to off-grid lighting. The goal was to design and build a device that could generate usable light purely from the potential energy of a falling weight, providing a clean and fuel-free alternative to kerosene lamps.

Technical Details

The core of the mechanism is a gearbox that translates the slow descent of a heavy bag into high-speed rotation for a small DC motor/generator. The electrical energy produced by the generator powers an LED. The design required careful mechanical considerations to maximize efficiency and light output duration from a single lift of the weight. It was a fascinating challenge in mechanical-to-electrical energy conversion.
