Project Overview
In response to the growing dependence on coal based power and the limitations of lithium-ion batteries, this project looks at alternative ways of storing renewable energy. Gravity batteries are a new big hope for storing excess renewable electricity. It proposes a potential and kinetic energy based system that could be applied in mountainous regions of India.
The model functions as a proof of concept, demonstrating how energy can be stored, released, and visualised through a physical working model.
Concept
The idea is to store energy by converting it into gravitational potential energy. Renewable energy, such as solar power, is used to pull a heavy load upward on an incline. Once stored, this energy can be released and converted back into usable power when needed.
Mechanics
A pulley system pulls a wheeled load, a car or train, up an inclined path. The system is powered by a dynamo connected to a solar source, simulated using a DC battery. As the load moves upward, the string winds around a coil. When released, the gear system ensures the load descends slowly and smoothly. During this downward motion, an LED lights up, indicating energy generation.
Conclusion
This project highlights the value of simple, physics driven systems in supporting renewable energy storage and encourages design approaches that combine scientific understanding with long term environmental thinking.
