Battery-electric “Infinity Train” will charge itself using gravity

 

Australian mining company Fortescue is working to clean up its own operations by 2030, while developing green solutions it can sell to others. It’s forking out into green tech through a subsidiary called Fortescue Future Industries, which has recently acquired Williams Advanced Engineering. Today, the two companies announced their first project together: an electric “infinity train” designed to move loads of iron ore without ever needing to be charged.
