Australia has deployed a groundbreaking freight train system that turns gravity into a renewable power source. Designed to haul heavy iron ore downhill from remote mines, this fully electric train generates its own energy as it moves—eliminating diesel fuel entirely. As the massively loaded train descends, its electric motors switch into generator mode through regenerative braking. Instead of wasting momentum as heat, the system converts the downhill motion into electricity, charging large onboa

Renewable energy company Green Gravity will install its electricity-generating technology at Number 4 Shaft coal mine at Russell Vale. 🔋 The deal between the company and mine owner Wollongong Resources is the first opportunity to demonstrate the technology beyond a prototype. | ABC Illawarra
