World Gravity Energy Storage System
The earliest form of a device that used gravity to power mechanical movement was the , invented in 1656 by . The clock was powered by the force of gravity using an mechanism, that made a pendulum move back and forth. Since then, gravity batteries have advanced into systems that can utilize the force due to gravity, and turn it into electricity for large scale energy storage.
