Can't wait to get my food that way! But jokes aside, that's a nice breakthrough!

Correct me if I'm wrong but from what I read the laser is an energy source for the graphene-SiO2 composite structure to heat the gas molecules behind and move.

More of a laser powered graphene engine than tractor beam ? Oh well.
