Graphene is diamagnetic, which means that it will levitate magnetically in a manner similar to the Meissner effect with superconductors and magnets. In addition, a sheet one atom thick has a specific area of 2,630,000 m^2/kg. It takes 60.2x10E6 J/kg to propel an object to escape velocity. So build a 200 km diameter coil of 20 turns of 10 ga copper wire on the ground. In the middle, place a graphene balloon 1,381 m in diameter. Slowly ramp up the current through the coil until it reaches 1 amp, and voila! The balloon will have been levitated to escape speed.

No need to thank me.
