A new technology from the startup Gravitricity generates power by dropping weights down mine shafts.
The novel idea relies on weight up to 3000 tons that would be suspended over a mine shaft, where it would be raised or lowered to expand or create energy. According to the team, the system could generate up to 20 MW of power, with a lifespan of 50 years. The system would also eliminate the need of battery storage, and give a new use to old mine shafts.
