The role of transport in sustainable development was first recognized at the 1992 United Nations (UN) Earth Summit and reinforced in its outcome document—Agenda 21. It is also part of objective 11 of UN 2030 Agenda for Sustainable Development. The improvements in the traditional methods of transportation lag behind the necessities. This video shows that Magnetic Levitation (MagLev) can fulfill the demand and fits with smart grid concepts. Moreover, the levitation method based on the diamagnetic property of high-temperature superconductors in the proximity of rare-earth permanent magnets presents advantages in comparison with other levitation methods. This technological solution was tested with the operation of a real scale prototype inside the campus of the Federal University of Rio de Janeiro (UFRJ), operating since 2014. The video presents a technological overview of the steps necessary to turn this prototype into a commercial product. The development is framed within NASA’s Technological Readiness Levels (TRL). A new transportation paradigm is on the verge of becoming a reality.
