The document proposes the SURBEL mobility system as a solution to mobility problems in Medellin, Colombia. It notes that the average travel speed is 34 km/h for short trips. The population relies heavily on cars for transportation, including 38.4% of trips under 5 km. However, the hilly terrain and lack of parking create mobility restrictions. The proposed solution is a clean, low-cost electrical mobility system using hydrogen cells, solar energy, magnetic levitation, and brushless hub motors for maintenance-free transportation.
