'Eco destructive' electric car motors need to change

Carmakers and EU legislators are pushing electric cars as the future of eco-friendly, sustainable transport – yet their motors are made using rare earth metals, the mining of which is "incredibly destructive to the environment."

They're the words of James Widmer of Newcastle University, who is part of a team looking to replace these rare earth metals with steel, which is cheaper, less damaging to the environment and more widely available.
