I've been reading up about graphene a lot lately

This could go into a turbine motor, and not just as a lubricant but since graphene also can have magnetic properties, it could improve the power output of them not just by reducing friction in the motor but an additional magnetic field that would amplify its output.
Really really cool stuff.
