Here is how they would accomplish this:

The most direct application of this research is the creation of longer-lasting nanomachines made out of single molecules, which currently are worn down by friction far more rapidly than larger objects because they have so few atoms to lose. But if scientists could one day work out how to control superlubricity on a larger scale, it could make pretty much everything – from cars, trains, powerlines and computers – more efficient.

To do this, the team simulated friction at the nanoscale by engineering two special surfaces: an optical lattice with peaks and troughs of electric potential, sort of like a tiny egg carton; and an ion crystal made up of charged atoms held in place using specific voltages and something known as the Coulomb force.

We want to see more efficient transportation and this seems like they are on the right track. (no pun itnended)
