GraviPower is a wearable, gravity-powered energy generation system designed to harness human motion for clean, off-grid electricity. Using a magnet moving through a copper coil embedded in a walking bag, it converts kinetic energy into electrical energy to charge small devices like phones or power LED lights. This low-cost, portable solution promotes sustainable energy access, particularly in remote or underserved regions. GraviPower directly supports several UN Sustainable Development Goals, including affordable clean energy and climate action. With its innovative design, eco-friendly approach, and practical real-world application, GraviPower offers a new path toward greener, self-sufficient energy use through everyday movement.
