How gravitational energy creates sustainable transport

You know times are finally changing in Australia, when a mining company run by the country’s second-richest person, Dr. Andrew “Twiggy” Forrest, opens a green hydrogen and renewables business. And when they acquire a bunch of engineers doing something amazing with trains, that’s when things start to get really interesting.

This week, Fortescue Future Industries (FFI), the green arm of Forrest’s ​​Fortescue Metals Group, acquired UK company Williams Advanced Engineering (WAE).

To mark the purchase, WAE and Fortescue announced the development of a world-first, zero-emission “Infinity Train.” 

What the heck is an Infinity Train?

It’s all about battery innovation. The Infinity Train project will use gravitational energy to fully recharge its battery-electric systems without any additional charging requirements for the return trip to reload.

In other words, the train will recharge the battery using gravity while it’s loaded with the extremely heavy iron ore it transports. Then, it can return home without the need for manual recharging. 

Erm, ok, so what is gravitational energy?
