We could soon have an electric Infinity Train that’s continuously powered by gravity and never needs to stop.
The Daily Mail explains:
“Train delays and cancellations are every commuter’s biggest bug bear.
But those relentless hold-ups would surely be minimized if there was a locomotive that never needed to stop to refuel or recharge because it had a constant power source.
And that’s just what scientists are developing with the help of a £38 million ($50 million) budget.
Their task is to create the world’s first ‘Infinity Train’, powered by the force of gravity, which will then be rolled out to a rail network later this decade.
It will run on an electric battery that won’t need to be recharged using conventional charging infrastructure because it will instead harness gravitational energy on downhill sections of a track.
The friction of braking to slow the train will re-generate electricity and theoretically mean the locomotive could transport materials and one day people without having to stop.
This echoes the 2013 post-apocalyptic science fiction movie Snowpiercer, where the Earth has frozen and a train carrying survivors must stay in perpetual motion circling the globe.”
But hopefully passengers won’t have to fight their way to the front of the train.
Greatest. Idea. Ever.
