Another week, and another graphene breakthrough has been made, with the creation of a new graphene-based device that could be placed in fossil-fuel-powered cars to make their engines ultra-efficient.

This new graphene device, built by a team at the University of Manchester led by Prof Aimin Song and Dr Ernie Hill, is being dubbed a ‘ballistic rectifier’, with the intention being to cut down on the wasted energy produced by a vehicle.

Based on the team’s concept, the ballistic rectifier would use electrical nanotechnology to convert waste heat from a car’s exhaust and engine and turn it into a useable electrical current for the car.
